I only had one remote for my vehicle, so I bought another one, I tried to program it but did not work and now my working remote quit working, the key pad did not work also, a mech tried to reprgram it but says I have a bad pcm, traced to a bad eeprom, if the pcm is bad wouldnt that affect the rest of the car, goes the keyless entry have its own module?
Do you

The keyless entry system uses the Central Security Module, not the Powertrain Control Module.

It is possible, the EEPROM is actually a computer chip inside of the main computer. The EEPROM is part of the receiving portion of the keyless entry, so if it fails then the transmitter's signals will not be read by the receiver (EEPROM).
