- Anti-theft systems are designed to prevent your vehicle from being stolen.
The system "breaks" the flow of electricity to the engine start sequence when the vehicle detects that a key other than the correct one is attempting to start it. Often, the system combines two critical components to keep the vehicle from being stolen. 1) The audible vehicle alarm Essentially, how they work is by an electrical circuit disconnecting to prevent power from flowing in some fashion so your car won’t start or to die immediately. An anti-theft system may also integrate a car alarm or it might be just an engine immobilizer.

2) An engine immobilizer. Essentially, how they work is by an electrical circuit disconnecting to prevent power from flowing in some fashion so your car won’t start or to die immediately. An anti-theft system may also integrate a car alarm or it might be just an engine immobilizer.
If your anti theft / engine immobilizer fails then a possible solution may be found in replacing the vehicle battery. If the battery dies then the key memory may have to be reset OR if the battery in the key remote dies.

Thank you so much for this video saved me because I had this issue the alarm is going off as I was in the car and as I was driving it down the road with everyone staring at me so when it stopped I noticed red light was on and I was in the car so I watched your video and was able to get out and only have to endure another five seconds of the alarm before silencing it
This video isn't a DIY learning tutorial as explained in the video title but merely a brief explanation on how the Honda immobilizer system works.
Thanks for the post. Tried to reprogram my key with a Frankenstein set of parts...now I know why it won't start 🤣😂
Oh boy! I hope this helps 😊
Great video, my brother. Succinct, concise & informative. Wish more on YT would learn from your brevity. Had a broken key, replaced the housing and the car--2007 Honda Fit Sport--just cranked, & cranked & CRANKED! Then I found You! Thanx ever so much. Keep up the informative vids. Stay Safe Cheers!
accord started with the transponders chipped keys since 98.. civic started in 02
Question... can thieve Hotwire the car? I have 2008 Honda Accord EX-L V6 with anti theft system. I have lock club that locks brake. Can a thieve comes inside and somehow unlocks or cut the club and Hotwire the car? Will kill switch do any good?
Do you know why the 2009 Honda fit sport factory alarm goes off at night when you use the key remote to set the car alarm on.
If the immobilizer circuit fails intermittently is there an output that can bypass this? Is there multiple outputs from the computer to remove voltage from the coil, injectors, etc? My Pilot is 17 years old and usually works but randomly does not crank flashing the key icon. Don’t want to spend $1000 on a car this old if it can be bypassed
Hello i have a 2005 Nissan 350z, when i put in the key, the car CRANKS but wont start, when i put in the key and try to start it, the NATS Alarm red light doesnt disappear..the red light stays ON.. After 20 attempts and 20 min unlocking the door, turning the key on and off the ignitation, etc, it will finaly recoginze the key and will start perfectly. On other days, the car will start perfectly and will disable the alarm all the time. On other days, i struggle trying to disable the alarm. What COULD this be?! Is it the Key or the NATS antenna amp , Body control module (BCM) or (IMMU) Engine Control Module (ECM??
Honda is sooo annoying why is it I have to pay every time this car goes into theft protection. Whenever it dies I have to do sooo much just to undo it
My key fob was broken and fell apart recently, and I lost that chip inside the key.
What exactly are my options now because the chip is definitely lost. I do still have the key so what I just need to go to the Honda dealership and hopefully they can make a chip?
so if the green light stays on ANY longer than this video, its the immobilizer? my 2003 honda crv is no crank no starting. i might needa change the fuses but i'm not entirely sure
I have an 05 honda and it looks like someone tried to steal my car overnight. Does the engine immobilizor stop the engine from starting if the key isnt present?
does a 1996 Honda Anti-theft system P/N 08E51-SV4-100-F have the Honda Immobilizer System? Thanks
I just blew some fuses in this exact car and fixed a few and now my car cranks but won’t switch out of park. I’m assuming it has something to do with anti theft and I have the easy peasy card so I reset my radio but I didn’t give me an option to reset the anti theft. Any tips? Or from anyone in the comments?
Thank you
very clear infos!!!
so all hondas have this? i have a 2014
So it’s a good thing that green key flash fast for anti theft?
Sir can you make a video how to program Honda Civic key
Question: when auto insurance asks what anti-theft category this is.... what number would that be?
I have a custom alarm on my ridgeline….im so glad it works
Would this cause my door switches to not lock when i press them??
So basically if all i have is a backup key that doesnt have a fob on it and this happens im screwed?
Mine doesn't start when the green light goes off if the light stays on it starts it chooses when it wants to start and when it doesn't
I have a 1998 honda accord, it also has the key chip feature. I got a new master key made for $100, they looked up the code and cut it from factory specs, instead of copying the 25 year old key.
Im trying to take the chip out of my key fob that is broken and use it in a new key . But I cannot find the chip . It looks to be aftermarket key fob but it is able to start the car so should have a transponder
What if the light doesn't even come on at all weather it matches or not because my car won't start (2009 Honda civic exl) my key light doesn't even blink wen I turn the key and its not staying on to inform me of a new key programming. Any ideas?
Fuse ???
Tengo un city 2016 y el control no abre ni cierra los seguros se queda el foco rojo prendido
My car like this flash key and don't starting ... How can fix ithis ... Honda civic 2008!!!
I have a similar issue with green key but my car starts and then one second later it does … I hired a locksmith to reprogram my key and it did not work .
Hi, thats an really usefull video. I have a doubt, I bought a new key without a chip, because I already have one original chip but the key case broke. Well I put the chip in the new and plane key, I made it match with the car and now I can open the Doors and stuff with the remote. Me question is, ¿Will I be able to turn the engine on once the keymaster had copied the key shape from the original one? Sorry for my limited english
Did it work?
@@JC-hu1wd it did! Also, the key wasn't an original!
How are Accords being stolen if the immobilizer is effective against theft?
I need to change entire lock cylinder in my 2002 crv. Will it work if I do
Nope . Did you figure out how to fix it ? Cause o just did it now my car won’t start
Hey I have a 2009 Civic GX that cranks but won't Start. The Green Key light goes on and off when the key is turned on. The Engine cranks fine, but the engine won't fire up. You hear the engine fire or pop now and then but won't run.
What should I look for?
Is there a PGM-FI main Fuel injector relay on the right side of the car behind the glove box like on other gas models?
Does this relay open a high pressure control valve to the fuel pressure regulator and power the ignition coils?
Same problem!! Any ideas ??
@@120DangerousHoldever get it situated ?
So does this mean the valet key has a chip too? Because my Fob stopped working last year so ive just been using the valet key.
Makes sense that it would
how could valet driver, start your car if it did not have a chip ??
My honda Civic car is showing the key green light and is steady on the dashboard.. i tried to program the car but its saying immobilizer not normal.. i have change more than 10 immobilizer yet not starting. i need help pls.
I need help too!
Thank you,
any idea about this issue. I noticed last night my electronic doorlocks did not respond aswell as the interior lighting didnt go on, then noticed the green ket flashing. Ifound that is Immobiliser issue, though i wonder why the doorlock and interior light would not go on, these are not connected to the immobilser are they? I tried looking at most of the fuses biut have not found a burned one yet, in the manual i dont see a ACG fuse as well. I got a European Honda Civic 2001.
The interior light still works when i switch it manually but not using the doors, kinda weird one
I am having the same issue. Anybody got any ideas how to fix it. I don't want to get locked out of my car again.
@@deelenagraves956 somehow i thought nk something shortened. The edu or EDC, can't remember the correct name. It's the computer board behind he glovebox did not recognised my key anymore. They tried things they knew but could get it to watch to. Even with a different second hand jelock and board. Now the chip is bypassed. Yet many electronics don't work no more. It does start now. But i have no electric doorlocks anymore, no airco, no interior automatic light. Lights on dashboard won't work.
Very informative. I'm stuck outside my car, my fob immobilizer died, finally broke into the car but alarm won't stop, have battery unplugged. Gonna see if I can program the key while dang a alarm goes off. Sorry neighbors 🙏
Did you get it fixed?
Plot twist when you get a key programed at honda and your battery dies along with the key fob battery it wipes the program entirely
Thank you for the input!
How come I am able to start my car with only the key and not the fob part...does that mean my security system isn't good anymore....it is a 15 year old car
Call a Locksmith, or even better, an Automotive Locksmith. They do keys with transponders for less than dealers.
My experience, honda does it cheaper than many locksmiths I've called.
what if the key light blinks?
Also don't put a blind ring around the switch! It will not start and the key light will flash!
is the chip inside the key itself or in the fob? - 2005 element.
Noseefood in the fob
my wife's 09 fit just started to do this today 3/14/18. her original key was replaced about 2yrs ago. i am not sure if it was reprogrammed at the dealer at that time. i find it strange that it just now started to do this after so long.
question is it the battery on the key fob or should i try the dealer first?
Marcus J. The battery in the key fob should be just for the remote. It’s my understanding that the transponder chip in the key does not need a battery; I.E. the owner’s manual of a 2002 CR-V says, “Do not open the key, there is no battery inside.” In 2002, the keys and the key fob remotes where not one piece. If the 2002 key doesn’t need a battery for the transponder chip, why would newer keys need a battery for the transponder?
Forget the expensive dealer, a locksmith that has current technology will be able to program a transponder key.
A good rule of thumb is change the key battery once a year just like you do your fire alarms in your house !!!
I have a 2003 Honda Civic and the key sign shows up and flashes twice for a few seconds then goes away is that normal?
+jay gets buckets That means your key battery is low. You can actually replace the battery pretty easily!
HowToCarGuy ok thanks. I thought my immobilizer was malfunctioning
HowToCarGuy i have the same problem this morning my car dont detect my keys anymore both of them at the same time, its not the battery, because they are not remote key they are only black rubber key Honda Fit 2005 so now im stuck in a friend driveway 385KM from home. i have this car for 2 yeat now, it never happened before... i have the green key flashing in the car, it try to start but no fire..
HowToCarGuy I have a 1998 Honda accord there’s no battery in the key ??

Hello, I have an emergent question for the video publisher really. My car (grand cherokee 2004) was stolen inside, but the theft didn't take anything away from my car as there is nothing valuable there. I found this happened this monday as I noticed my car's door is ajar and pretty massed up inside. However, I didn't use my car since then, and today I want to drive for shopping and found it doesn't work. It looks like when I started it, it sound like "clicking", and no crank up. I am just not sure if it is the starter problem or the anti-theft programming problem. The car has enough battery and power. Thanks for any reply.
Hey Derrick, I am having somewhat similar issues with my 2011 Honda accord that I bought just a week back, It is really cold here but I don't think that's the issue my car is not starting up, rather something with the anti theft as you mentioned because I am thinking I might have messed something up while I was wondering around the car and the alarms also went off once
@rushil505 it's quite funny that you tried to help him despite the fact the comment was 5 years old when you replied.
please help me my key car was working great until I try programing the original key to make my lock button work now I cannot remove the alarm and my car wont start any advise or help you can provide me with please and thank you
Did you ever find out what it was?
@@jaimeslife2953 nope I just had to deactivate the alarm
@@marthaocampo5856 how’d you deactivate it?
@@jaimeslife2953 my dad remove the fuse and that’s all he did
So, does this make these car unstealable with a screw driver or hot wiring?
Any car that you can program a remote starter on the IF key check should be able to be bypassed.
PizzaLover I’m sure 👍🏻👍🏻👍🏻
So then, my Mom's old 1996 Honda Accord does not have a chip in her one key? Thanks
Wow how much mileage is on that car?
If the key fob was dead would it trigger the same response?
Yes
That being said, are accords a safe population from theft? I've commonly heard hondas are most easiest to break into
Can you copy a key w/o the remote - that would work?
All cars are easy to break into. Remember honda and toyota are the best selling cars so theyll naturally just be stolen more simply because of the odds. Most honda and toyota cars arent stolen. There just the most stolen because they are what exists the most
Well, they are kinda the easiest to break in. Just used a flat ruler like tool and you're in. I think it was honda accord 2007 or so that was the most stolen vehicle. But yes they are reliable that's why they're stolen also.
still there?
A VERY BASIC SNAP ON SCANNER CAN WIPE ANY MODULE AND REPROGAM KEYS ECU ETC IN A 2003 UP HONDA FYI
Really
How?
First of all it needs to be used by a technician or someone with basic level of understanding of how to use a scan tool. From that point on it is intuitive and the question of how it is done can be answered a multiple of ways depending on the scan tool used. Basically you open the scan tool and get to special function menu for the pcm and look for pcm replace or immo functions
Would this prevent the alternator from doing its job if it was like this for too long. I have a Honda fit key that is broken so I’m using the piece of the key the rest missing.
Some cars lock the steering up when its started without the key but i figured out you can just take an angle grinder and cut the collar holding the bolt in off
What are you cutting?
Brock, which honda is this?
Neal Singh
If you replace the transponder, do you have to sync it with your keys or ecu?
Yes
Both
What is the DIY in this video??
Have the same key, can't get the little screw out to change the battery.
Hi komit73 Thanks for the comment! I will be posting a video that may help you with that! Is the screw simply "stuck" to where it will not turn? Thanks again!
Brock Frady
Yes, it won't turn.
+HowToCarGuy i will also be interested in that video. subscribing now.
You've been miss informed, honda uses transponder keys on honda as early as 1996 in UK, and 98 and up on usa.
+chinolashtla I know the US Accords had the transponder since 1999. I think by 2003, all Honda models have it standard.
chinolashtla *98 accords
Yes my 1998 Honda does not have a battery in the key so it must be a transponder !
2003?
No sooner than that.
2001 in civic.
You can also program your key at third parties or diy.
I have a 2001honda Accord with key n chip
But I don't see no light in my car
I bought a honda from used car dealership and I opened the key to change the battery and I try to start the car the engine starts but shut down immediately i though I bought a lemon car so I go to the dealership and start a fight 😆😆😆😆 all along this was the problem thanks for the video
WOW! I am so glad I could help you. Thanks for stopping by!
That's me lol
Problem when disconnecting car battery as well.
Use your factory system to a amp and watch.facttory hit hard without battery problem.
what if the green key light is coming on and the car wont start?
eileen Clow Your anti theft was activated. It needed to be reprogramed and then it would have started.😳 but this was a year ago.
Mine is doing the same. Green light but no start.
Julie K Munden is the battery in your car key dead? Go find the 1616 battery for it, that's what I did and it started right up the first try. Hope this helps.
Yes, got a new battery and it still won't turnover. Ugh!
Julie K Munden just to be clear, are you talking about the actual battery that powers your car, or the battery that powers your key that unlocks and locks your car? Just for clarification
Can these cars be stolen?
any car can be stolen.
My battery in my Honda Clarity 2018 went dead we charged it then it wouldn't shift they told me to tow it in. I found that losing power or changing the battery causes your anti theft to be enabled so not to be able to put the car in gear. All you need to do is put the key in the drivers side door, lock, unlock, lock it will release and you can shift gears. 6 people told me to tow the car.
I can’t get the car to turn over. It turned over first right after the change and now it won’t start
@@stephiecee7232 did you resolve this ?
@@calimestime I did. It was the starter and I changed it all by myself but woohoo
since 03? LOL ok since 98... Honda has put a chip in the black rubber like material on the keys in order for it to start your engine not since "2003"
+LACounty818 he said every car dingus
LACounty818
Yes my 98 Honda doesn’t have a battery in the key Fob !
He said you " have to have it programmed at a Honda dealer " that's a crock of bullshit !
So where's the DIY part?
Someone tried to steal my car :(
OH NO! I hope they were not successful!
HowToCarGuy no they weren't, I have a car like in this video that has an alarm and it's a very quiet neighborhood at night and the man was on foot, it was 3am when he tried but thankfully my neighbors dog was barking and alerted me to look out the window, and I see this man peaking into my car with a flashlight! I was mad but as soon as I was about to hit the panic button on my fob he moved on
Since 1998 guy
waste of time my Honda still will not reliably run because of the anti theft system.
Anti-Theft my ass, it's just a way to keep people from getting replacement keys without going to an approved dealer and paying the royalty.
You gotta understand the way car-companies think: with their wallets first, and the customers second.
Totally agree with you.
or you can take it to anyone who has a scanner, your buddy Joe can do it in your driveway in a few seconds provided he's ever actually worked on cars and owns a scanner lol
Hell yea I agree ☝️
I have the same year Honda Accord and I’ve had so many god damn problems. I hate Honda. I’ve had the alarm go off 3 god damn times, once in the middle of the night. I had the right key, everything was fine, the stupid car just would f up. I hate Honda, I hate the horrible 2.4 engine barely cranking out 200 horsepower, the horrible acceleration, horrible transmission, horrible looking car, horrible cabin noise, horrible god damn everything, I hate Honda more than I can ever imagine, they suck. I don’t care if they’re reliable whatsoever, every car in the god damn world can reach 200k miles. I hate Honda, I hate Honda, I want an actual god damn car like a charger or a magnum, not some garbage box Honda Accord that takes 5 years to get to 60! Hell, entering a highway is so hard because with the pedal to the floor, the car isn’t going anywhere!! I hate Honda so much, I want to sell my pile of garbage to some other owner who will hate it too.
immobilizers were implented in 1997 in the US for the Prelude. 1998 for Accords. Don't misinform people you lose credibility
Well these keys suckkkk
