Theft Relearn Procedure For 2008 Chevy Malibu

My security lock light is on and don’t know why or what to do! but my car will not start! Please help!

Protech:
What year and model car do you have?

2008 Chevy Malibu.

You can try a theft re-learn procedure, but it may only be a temporary fix. More than likely you have a problem with the ignition cylinder and/or key, with the security light on there will be a trouble set in the body control module.

Can you explain to me how to do that so i can at least take it to my car dealer tomorrow!

It will take about 30 minutes, so you need to make sure the battery is fully charged, or have a charger on it while doing the following procedure…. take the ignition key, and turn on the ignition….do NOT attempt to start the car, just turn it to the ‘on’ position. After about 10 minutes, the security light will go out. Now turn the key off and wait 5 seconds. Now, turn the key to the ‘on’ position again… do not crank. After another 10 minutes, the light will go out again…..do this procedure one more time for a total of 3 times and 30 minutes. After the last time, and the light has gone off….turn the key off and wait about a minute, then start the car. That is the procedure.

Thank you will give it a shot.

Glad to help, hope it works for you!! have a great evening!

I’m back no luck with the re learn procedure for the Chevy Malibu! any other suggestions.

Unfortunately, no…if it still will not start, you’re going to have it towed into the dealership. there must be something wrong with the actual theft module or other wiring problem/module failure. just to check, you are using a factory key right? if you’ve had a key made or are using a non PK3 key, the car won’t start no matter what.

Yes.

OK, then sorry to say there is no other way to start the vehicle….maybe retry the procedure in case you didn’t do it completely or correctly. Do you have any aftermarket accessories, like an alarm or remote start on the car?

Keys were stolen about a month ago just have the other factory key! do you think if i got another starter for it it might work and fix it?  Remote i mean.

OK, let’s start from scratch again…..was this the first time you were trying to start the car with the other key? and NO, another remote will not help the problem.

No been using it for 4 weeks this Friday!

So it did work previously….you must have a theft deterrent module problem, or a cylinder that has gone bad. you’re local dealership will be able to scan the Malibu and tell for sure.

I’ll just have it towed tomorrow thanks and have a good one.

Thank you, you too!

Without notice the securiy system will activate and the car will not start. we go through the process and reset the system… however it does not stop the security system from activating again. can i de-activate the system?

ProTech:
October 23, 2011 – 6:59 PM.The relearn procedure that you are doing is just a temporary fix, the problem will always come back. You cannot de-activate the security system or the car would never start. Most likely you have a faulty ignition cylinder and Passlock sensor. It would need to be replaced and reprogrammed. That should take care of the problem.

Car wont start. Good battery good connections starter tested good.

ProTech:
Does it crank?

No.

Well if you’re sure the battery and starter are good, I would look into an ignition switch or security problem.

Someone told me even though the starter tested good that under load it could still lock up.

True, but if it’s not even cranking it is not getting a signal to start the car. Unless you’re hearing a loud ‘clunk’ or ‘click’ type noise when you turn the ignition to ‘run’, it probably is NOT the stater.

Earlier i jumped the solenoid and it engaged but no crank.

I would check for power on the purple wire at the solenoid when you turn the key to ‘crank’. If you have 12 volts there when you are trying to start the car, then you do have a bad starter.
