the keyless entry and stereo stopped working at the same time, the key fobs will work when the ing switch is turned on,

Receiver for the fobs? Hopefully (cringe) you're still under warranty.

My stock AM/FM Cassette radio stopped working after 40,000 miles. The AM works, but the FM sounds like the antenna is disconnected. I ended up putting a new stereo in for Christmas. I don't have keyless entry, so maybe its a flaw with the stock radio.
