Sounds like the key got wet and the battery inside it is going dead /// chances are if you use your spare key then you won't see the security light

Changing the battery is easy but I like to do it quick so it won't lose'memory.(most have flash memory but this old dog can;t break old habits) Keys are easy to program but you have to have 1 good working key to do it..... Ebay has keys for your car at less the $10 for 2 but you have to get them cut then it's east to program the (the car does all the work .. all you do is follow the simple instructions

Sounds like an intermittent electrical problem with the security system. These are a real bugger to diagnose and repair. Normally I don't condone throwing parts and money at a problem. But you might want to have your local Chevy Dealer replace the ignition lock cylinder assembly and program new keys to the car. The lock cylinder is prone to wear, especially on a 14 year old vehicle. Also, if the security system has any stored trouble codes that will lead them to the problem. A scan tool that can communicate with the anti-theft system is required. Most little shops and garages don't have the proper tools or people who know about this kind of problem to be able to deal with it a fix it correctly. HTH. -Jim

My last mechanic spliced​ a wire why he was trying to fix the anti theft system and now if it doesn't start I have to raise the hood and take that wire and put it to the battery and Spark it up to make it start and I don't like that???
