Can anyone offer any insight?

If it is at the dealer and he has found the problem let him have at it.
The only thing I would check out is.

Tip on going to the dealer
Ask that only a factory certified gasoline engine performance specialist work on your car.
Not all dealerships are concerned with how repairs are dispatched, and not all dealership techs bother to take advantage of the training offered by Factoty (the vast majority of which is paid training). If the dealer is uncooperative, ask for your money back and call around for a dealer that will accommodate you.

Good Luck

Just remember, this can void your warranty!

Mine is an '05 Sedan, not the Maxx, but I'm going to assume that doesn't make any difference in this case.
Guess I need to go buy a few $$$ spare keys!

Thanks!

I just insert the key into the ignition by itself, i.e., no keyring weighing it down. Haven't had any problems since...

There might be something here. It seems that the highest failure is with women. The only thing they've seen much the same is HUGE keychains or many keys and stuff on there. They think that weight causes the failure.

I just want to be sure on the correect fix to my car problems. I have a 1998 malibu with the 2.4 L 4 cyl and 130,000miles. Sometimes when you get in to start it the theft deterrent light flashes and the car will not start. Had it to a dealer and he said it was the tumbler for the theft sys. I assume that is in the ignition switch. Usually after 10-20 min the car will start. Will cutting the yellow wire/switch insertion work or do i have to do something else. PLEASE HELP Thanks

[ponchonutty]

Nope, you have the classic PK2 failure.

2002 Chevy Malibu, I've had the theft light problem a lot and now I have a new problem and I'm not sure if it's related. Occationally I'll go to turn on the car and it won't start, but not only that, none of the gauges show anything (0 fuel, 0 rpm, 0 everything) but the car is getting power. (CD player works, fans work, dome light, head lights). When it does work, the theft light is usually on, and while driving all the gaugess will occationally turn off and turn back on arond 10 min later. Is this theft system problems? What could it be? PLease e-mail me.

I wish I could provide you with some positive or helpful information for your passlock system. I had a 2002 Malibu LS and experienced the same exact problem. I had it towed, several times (I thought AAA was going to drop me at one point). In fact, the local tow truck driver knew me and asked how my roomate and family were b/c of his frequent visits. The local chevy dealer told me the first time I had it towed, that it was the computer and a module had to be replaced. They said if this happened again, the computer would need to be replaced. Well, it happened again and I was told this time that there was an update the computer needed and it should be ok. Then it happened again. I bought a honda 3 days later. Prior to my recent purchase, I had always had chevys, with minimal problems. The malibu I owned was a nightmare. In addition to the passlock system, the breaks and usually rotors required frequent replacing and usually started shaking and vibrating after 3,000 miles, but usually they said the breaks were fine so I would drive it like this. $1700 went to fixing an internal dex-cool leak. I replaced the ignition switch and ignition cylinder 2x. I'm really sorry to hear of your problems with your malibu, in the end I had to get rid of mine. The most frustrating part wasn't so much the car being so problematic, it was Chevrolets refusal to recognize any of these problems which I think sadly has cost them much business.

This is what I've found out and I've read the service manuals, and it sure seems doable.

Connect a resistor that would be within the normal range for the passlock system......

1. Attempt to start car; it will crank and fail, with the security light flashing. Leave the ignition on for 10 minutes, until the security light goes out.

2. Repeat step 1, two more times.

3. Car should now have learned its new key cylinder, or in this case, new resistor.

I don't know about the resistor trick, i just cut the passlock wire and put a switch in. I've even unplugged my battery for a few hours, and switched the switch to enable it. turned the car on, and then disabled while the car is running. It's easy to do, skill level 1 i'd say. You just need wire strippers (a knife could do it) and a switch from radio shack. I soldered long wires to the switch and then just wire knoted it to the other ends of the security wire. I'm sure you could do it with out soldering, just loop the wire in the hole that comes on the switch.

[ponchonutty]

Yes but the switch is totally unnecessary. With this resistor constantly grounded to the "input" wire on the PK2 system, it'll always work. There's no reason to flip a switch.

[Sayguh]

Do you have any documentation on it? And also what resistor value is in the proper range? Has anyone else tried this?

[ponchonutty]

I've talked to a few other remote start installers that have done this to vehicles that are had the security light comming on even before they did a remote start or other installs. The procedure I listed is what you have to do when you replace the ignition cylinder.

HI I am having the same problem as most it seems with the Malibu pass lock. I went to start up the car this morning and the Theftloc light is on and car will not start. I have cleaned the key, left key on for 10 minutes, unlocked the doors with the key etc etc and nothing is working. I called chevy and they want to toe it in and in a not so nice way told them unless they wre going to pay for it heck no. There are to many others having the same problem can anyone else tell me another idea plz i am going nuts over this
