How do I reset the memory on my 2002 impala after the battery has been replaced

Asked by Oct 25, 2015 at 12:30 PM about the 2002 Chevrolet Impala Base

Question type: Maintenance & Repair

I have a security issue with my 2002 chevy impala. I let it sit 10 mins and it
usually resets and the car starts. My battery died when I was doing this and I
took it to bee charged and found it was bad, so replaced it. It had been out of
the car for 24 hours, now it wont start. I need to know ow to reset my
computer since there has been no battery keeping the memory.

This should have no effect on the security system. The only things you should lose by disconnecting the battery are the clock a radio presets. Your Impala is currently under recall for the ignition switch. Contact your local Chevrolet Dealer and have them take a look at it. Sounds like a problem with the anti-theft module in the steering column. HTH. -Jim

When you say you usually let it sit 10 mins it resets. This has me concerned, how many times have you had to reset this? why have you had to reset this? Yes the reset procedure is to let leave the key on for ten mins then shut it off then try to crank If it does not start you do this up to three times. But if you are doing this on a reg basis you need to have your ignition switch replaced, As Jim has stated there is a recall on a large number of GM cars and yours may be one of them.
