Asked by Trick2008 May 10, 2008 at 08:21 PM about the 2002 Chevrolet Impala

Question type: Maintenance & Repair

Is there a known repair for the security light/passlock problem that causes Impala and other GM products not to start for 10 to 30 minutes? If it's replacing the BCM at $500 that's fine, I just want to know that it will work. Thanks.

Does this have the PASSkey ignition system, with the little resistor button in the key, or does it have an RF chip in the head of the key which you can't see?

I wouldn't look at the BCM with passlock it could be a ignition issue or a the passlock cotrol module your gonna need a scan tool or you need to find the electrical values and ohm them out

I had the same problem with my impala and what i did was go in though the radio in the settings area and reset the FOB and the car started fine but i did have to get a new ignition put in the car not the BCM

I am having the same problme with my 2001 Impala LS. Unfortunately, this problem is not limited to Impalas nor Chevys, but is a GM wide issue. The first thing to try to replace is the ignition switch (not the whole ignition, just the electronics). It's a little pricey at the dealership, but for those that are technically inclined, the part is relatively inexpensive. If that does not solve the problem, the Body Control Module (BCM) will need to be replaced (500-600 dollars) and that will also need to be programmed at the dealer (or by any mechanic that has the proper equipment). Even after all that is done, it is only a temporary fix per se. GM in a Technical Service Bulletin to its dealerships admits that after replacing all the components of the PassLock 2 system, that the problem can recur. I have heard stories of it recurring within a year to 2 of the initial repairs. Anyway, time for me to find a new ignition switch and see if that is where my problem lies. Best of luck

Here's the "fix" I just did for my 99 tahoe. Took the cover off the steering column, unplugged the sensor from the cylinder *while* the car was running. it's a 3 wire plug red w/ white, orange w/black and yellow. From then on, the car will always start and ignore the sensor. The only negative is the security light stays on. But, I plan to just remove the bulb. Replacing the BCM only postpones it from happening again. Check out the following links. As an electrical engineer, I also believe there is an inherent design flaw because there are too many issues reported. Good luck. http://car.justanswer.com/for/ce07-bypass-lock-sensor-1998-chevy-tahoe http://general-motors.pissedconsumer.com/gm-passlock-ii-system-has-major-inherent-design-flaws-20080502119601.html

Thank you!!!!! I changed the FOB Light setting to OFF and it started right up. Been having this issue intermittently for years. Haven't had it for more than 6 months and then today. Argggh! I was going to beat my car with a bat! Then I googled & found this post. The dealer thought I was just a stupid girl who didn't know what I was talking about and brushed me off because they couldn't duplicate the problem. They can suck it!!! Thank you. I love the Internet!
