I believe that vehicle has a 'PATS' antitheft system. There's a special 'chip' in the key that tells the car it's the original key and not a copy.
There is a way to 'hack' the antitheft but, to maintain the security of everyone that has a system like this in thier vehicle I won't post it.
Like for most factory codes for radio's or other antitheft system problems if you bring your vin# and/or registration (vin is on there too) and maybe state licence to prove you own the car, you can walk into a dealer and get the help you need without bringing the car in.
Decent dealerships will know everything from a vin#.
If they wan't you to bring it in, it's because they wan't to make money for it because they need to get a number off of a module or other service that you may not be able to do. Try a different place.
Also a car audio place can help if the installer's are talented and familiar with remote starts.

Most likely the starter wasnt the problem but rather the anti theft security that comes standard on these cars. It all stems from that chip in your key. When not funtioning properly, the SECURITY light comes on and the starter turns off to prevent theft due to not getting the correct signals to the computer. Look for the security light, if its there, then this is your problem. This site will help with info and DO IT YOURSELF solutions.

99 Grand am Security light comes on every time and car wont start


you cant disable the unit.. it is integral with the engines computer.. turn the key to the on position and leave it for 10 minutes.. the security light should stop flashing in 10 minutes or so , when it does , start the vehicle.. if it is a recurring problem , replace the ignition lock cylinder as it is a common problem with these cars.

TRY THIS RESET FOR THE SECURITY SYSTEM.

PASS LOCK RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
