Mate, you’re a bloody legend as you’ve saved me $165 to do a 5 min job. Who knew the Mazda emblem on the fob came out and a screw was hiding underneath. Thank you so much. Best TH-cam video in years. 👍👍👍
This is the best video for Mazda key fob replacement because it opens the key-spring assembly and points out the immobilizer. Here are some tips though: 1. If you are using a new key fob, your new fob won’t work without the immobilizer. The immobilizer is simply a small magnet as pointed out in the video at about 4:15. 2. Remove the immobilizer by simply turning the opened assembly over and tap it out. In my case it simply dropped out without any extra effort. 3. If you are using a new fob with a blank key, any professional key cutting service can cut it for you. For me it cost about $10 and took 10 minutes. 4. Instead of programming a new fob, you can just transfer the battery and electronic components from your old fob to the new one.
you are the only video that mentioned the mobilizer. I switched a fob & car would not turn over. I've been working on this for hours and not one video mentioned mobilizer chip. Thank you so much
Thank you for helping me save nearly $200 for my 2008 Mazda5 fob replacement. I ordered a generic fob/case form ebay, and had Home Depot copy the key. I used everything from the new fob except the radio circuit and the small part of the old fob that houses the immobilizer, and the old screw for that part. Spent
Thank you so much!!! I was panicking when I accidentally broke the tooth part of the key while I was trying to replace the battery... I will follow your instructions! Thanks for the video. You saved me a lot of money and a major headache!!
Very nice video to show how to change the key & spring. Bad ass looking switch-blade action there Mazda! As a guy who has repaired vehicles from the late 60’s and ASE Master Tech in 1978, please use a finder cover if using the hood as a light duty work bench. It is, at least to me, disrespectful to the customer and protects the finish. Painting the hood on a solid color 10-15 year old vehicle is not easy to match and a lot of work. Also, every good tech has some super glue in the tool box. Right!
You should at first split the fob part of the key and the second part with electronics however this DYI is useful for those who need to change battery and cannot split mentioned parts because somebody glued them together because of broken hook in fob part. So in this case you can replace a battery by removing upper part of the key (with buttons) as on video at 1:29 min.
You probably already figured it out, but the immobilized is just a magnet in a small slot that was pointed out in the video. To remove it, you can simply turn the opened fob upside down and it should drop right out. At least it did for me.
My key fob fell out of my pocket and fell on the ground and everything came apart. I put it back together but for the life of me it would not turn. After watching this I realize the immobilizer fell out and it was so small I did not notice. Do you know if I can buy only the immobilizer from Mazda?
Great video! The whole time I was thinking please put everything on a nice clean towel so it wouldn’t scratch the paint or the parts roll off the car. Good job though! 👍
My Mazda 3 key no longer pop up. Open the key as shown in the video to find out that a plastic part was broken. Searching and found key flip shell on ebay for $3.80. Thanks a lot.
when you put your key into the ignition. The immobilizer is just a small transmitter, it sends out a signal to a receiver in the ignition area, and that tells the car that the key is the 'match' to the computer car memory records and allows it to start. if you simply flip around the silver key and forget to take the immobilizer with it, that silver key will fit the ignition...but no transmitter means the car computer will think your key is 'invalid' and won't allow the car to start. that's about all i know from googling it all. hope that helps. best of luck!
Yo lave mí mazda 3 M-2011 lo usé escuchando música, y lo lave, cuando quice encenderlo, ya no encendió, y estaba muy bien antes de lavarlo, pero metí la llave para arrancarlo y no arrancó.

How did you have Home Depot copy the key? They usually don’t do keys unless the key is bought from their machine.

Perfect instructions. Fixed my keys in no time! Thanks a bunch!
Great tutorial sir. I just fixed my Mazda keys with your help. Much appreciated and "liked".

Great video. I didn't know about the inhibitor until I saw your video. Now my key starts the car. Thanks
Anyone knows how to remove the immobiliser to transfer it to new case ? Unfortunately the video is missing the most important parts

I don't tend to do such projects on the bonnet of my car - high risk of scratching and losing something small

Thank you I am your fan now. You save a lot. OF TIME AND MONEY
Okay guys, thanks for the info guys, good video guys, I love your style guys, keep up the good work guys.....guys.

So the immobilizer is linked to the circuit board correct? If you are just swapping the key then the immobilizer and the circuit board must be paired?
Yeah he didnt even show how to switch the immobiliser
Thank you for the instructions! 👍🏼
Gee thanks, you showed me the easiest way to open the battery compartment. The other video showed the difficult way
This worked on my mazda 3 2008.. why is it there is no beep sound when locking and unlocking?
None of these parts open this easy. You will end up breaking them or have major scratches on them. But, thanks for the video.
Great explnation, only bit confusing switching keys and you went bit too fast had to replay certain parts. But fixed my keys less tham €15
Thank you so much 😊 wonderful
How about Mazda 2? Will this work?
Yes but he didnt show how to take the immobiliser out
Can you explain what the immobilizer is or does because i dont know why my key cannot start the car anymore 😭

I took apart the key fob and put the metal key part in a new fob, and now I’m getting the security system on my cx7. Any idea what happened?
The immobiliser. He didnt show how to replace it but did mentioned it in his vid
Need to switch internal components of old into the new
What battery does it use? Just wondering
Thats CR1620
Clip the point off a small nail and drift out the pin. It's not in there super tight and it's way easier than fking with that spring.
Thank you very much.!!! Done.!!!
Cool. But don't put tools on the bonnet for gods sakes.
How make the same but with new smart key???? (mazda 6 year 2015)
You got the wrong key You took the replacement key and you turn around and took it off and then you put it back
Mazda you are fired. I can't even open the trunk without the keyfob.
Ofcourse the key spring bit u cover entirely with ur hands so i cant see anything i need
I lost keys for CX9 what are my options?
$$$$$$$$
So what did you do? I would imagine contact the dealership and they would make a new key based on your vin number.
How the hell do you get the spring to match up with key before putting together, total crap.
The spring should be attempting to force the key open and the button should prevent it
