Turn the key on and wait for 10 minutes, watch the security light, when it goes off turn the key to the off position, wait 5 seconds then turn the key back on for 10 minutes, wait for the security light to go off before you turn the key off, do this 3 times and your car should start after the 3rd time.
Same happened to me when I used the spare key one time turn the key to on for ten minutes then turn off car for five seconds then turn back to on repeat 3 times then the car will start I've never had any issue with it since my 2011 Impala has been great haven't had any issues with it but have heard alot of bad problems with them
Whoever still needs this ik the problem. Just happened to me today I guess the transmitter fell out my key onto the mat. Luckily I found it. Put it back in the key started right up
when your turn key to on position, headlights turn on(for 10 minutes, twice) hence battery saver mode.. your can turn off lights by just turning headlight knob to left then letting it go & it springs back to where it was & lights off. when you did that 5 second thing, that was more then 5 seconds & you only did it 3 1/2 cycles, like on off on, as opposed to 3 full cycles.
I just fixed my car from this problem a 13 Malibu its the newer model after ur model so idk how similar they are under the hood , but unfortunately they have multiple reasons as to why the theft service system could be triggered for me it was as simple as buying a new battery if ur battery is faulty it will set it off because of the quick changes in voltage which will set off the alarm or theft system. My battery seemed fine but would drop to 8 volts under the load of starting the car bought a new battery and it’s gone and back in business I hope this is the case for u 2 bud 🤙🏽.
have you tried turning the alam off? turn key to on position- hold tune/dsply until menu comes up-use seek to change setting selection until ALARM is displayed-use the required key (not sure on that year car) to change to ALARM OFF-hit tune/dsply to exit settings-leave key in on position for 10 min (until the power shuts off) the alarm (passlock system) is now off & shouldn' keep the car from starting
@@vincek72 tune/display is a smaller knob on the sound system (with a dial) it should say tune/display on it but it could be worn off bc of the age of the car
I lost my only key to a 2013 impala and had a new one cut from code (85 bucks). I did the 30 minute program process many times thinking I was doing it wrong, that on/off 30 minute process. The key was starting the car after the first program process but I had that "Service Theft System" message and indicator still showing. I tried so many things I found on the internet and the last thing I found and tried, weeks later was to disconnect the battery. So I disconnected the battery for a couple of minutes and mine cleared out the message. I was just worried that later down the road the car would shut off if I didn't get the message to go away. One other weird thing was I found the old key I had lost in the middle of this mess but was told the old key would no longer work after programing the new key with that 30 minute process, but now the new and old key works, I can only assume that I had done the program process so many times with both keys when I was trying it so many times in desperation and I must of had programmed them both.
Hello guys I no longer have this vehicle anymore. lol but if I remember I had to purchase a new key fob to disable the problem. The old key I had the chip inside the key somehow stop working
Smart move trading it.Had mine for 10 years and it started giving me tracking control problems and the rear end starting make horrible noise.Replaced struts,wheel bearings sway bar links and still couldn’t find the problem.
@kerrybriggs1128 probably a speed sensor. Need a advanced scan tool to read live data to see what the pcm sees. If it has a glitch in it it'll disable the traction control and stability track😊
I’m in the same position. I did the process twice and yet again, nothing. I have a 2014 Chevy Impala limited. My car starts with the message, but I did just replace a dead battery with a new one and I’ve tried to disconnect the new battery to see if it resets and it didn’t. Please help
@@imdatguy80 wow man i just bought a used one and got a spare key made at walmart for 35 bucks. worked fine and it took me less then 15 seconds to program it myself. so if you ever need a spare hit up walmart.
honestly it’s up to you. I believe the impala line are very reliable cars with minor issues that can be fix. As long as whoever your buying it from kept up with the maintance on the vehicle you should be ok.
@@rockets4life701 okay, thanks. I'll try it. I got a message first saying "engine power reduced" then the car won't start... so I cleaned the negative terminal cause it was due for a cleaning, then I try to start the car after and then I got that "service theft system" bs.

I'm having this problem with my car was really hoping a reset would do it somehow and not a new battery but sounds like I might now .

You’ll have to go to the dealership and buy a new key fob and pay for them to reprogram it
There's a a video of this year car you have on how to clear the anti theft
My cars doing the exact same, did you get yours fixed if so how? Please reply
Chris Lolol yes i did get it fix. I end up having a bad chip in my ignition key so i had to pay for a new key and for the dealer reprogram it

Dante josey how
Turn your key to acc push in an hold tell your setting pop up an scoll through tell u see security or anti theft and turn it off
You make no sense can you type it again

I do recommend try buying a new key fob from the dealer and have them program it.
@@imdatguy80. Did you sell the car because of problems. ??? I’m going to buy one that only has 50k miles. Should l get one

@@cincoy3679I’m sorry to answer your question no I didn’t sell my car because of that problem. I traded in for a new impala which I have now
Put the key in driver door and hold for 60sec.. that’ simple
Do you turn the key for 60 seconds? Or just leave the key in?
@@dhatbwoy696 turn key and hold for 60sec, then turn the other way and hold for 60sec
