key system error

Postby eclipse95blk » Thu Mar 26, 2020 6:52 am

Anyone found the reason for the key system error light on dash. I know its not the Key Fob battery or the main battery cause they were all replaced and still having the issue. tried resetting computer and nothing. Everything work fine with the key only the annoying dash light. Last option it the dealer, but they may say replace BCM and reprogram

I had my fobs randomly flat out die. I had two get two new fobs and a reprogram under warranty. Only way I could start the car was pushing the start button with the fob.
