I had the same problem. Try cleaning the key with alcohol and a Q-Tip
Then reset the clock. Also, check the ignition switch. Your ignition switch could be worn or lose. It can also be dirty. Blow air into the ignition switch to clean it.
The key is not sending the single to the ignition switch properly and therefor the radio is not getting the voltage to the memory in the radio to keep the clock set.
I had the same problem when the Security Light came on and I thought it was a Passlock problem.
My key was dirty and my ignition switch lose. I'm going to try to tighten up the ignition switch and see if that solves all my other problems. If that doesn't work I will have to replace my ignition switch.
