Passengers door lock failed to open when car parked after a drive, car would not start, trying to get lock to open. A day later car would not recognize key (red light flashed on key). Analog clock looses synch with computer time. Problems, except clock, seem to fix themselves after a few minutes. Car had a moment of hesitation while accelerating as if something shut off, radio went off at same time. Car says that key needs new batteries even though I just put in new ones,( car said I needed them last week) This just popped up
What makes this problem better or worse?
Nothing, just fixes itself

Hello, I would not recommend rushing to judgement about replacing this component. I'd suggest testing to find out what's going on. What if there's a wiring issue? A water leak on an electrical component? Something else going on. Guessing at part replacement - especially one that would require a proper diagnostic tool to program when replacing it -- is not the best choice.
There's no real guess here either, no "common" thing to look at; hands on testing is needed.
