Occasionally my 2006 HHR door locks will "chatter," or unlock and lock while driving. Sometimes it is just a "pulse," to ONE door ! Is this a computer problem appearing ? I've checked status of my keyless-entry fob and all is well inside.
Any ideas ?

I would suggest leaving the key fob at home and go take a drive. See if the problem goes away without the key fob around the car.

 

There was a member that had this problem only when his wife was in the car. Turned out she had her fob in her purse and all her stuff was hitting buttons.

Then there was the guy, for reasons of his own, kept the fob in his pants pocket instead of on the key ring.

The fob sends an RF signal to the RCDLR which sends a signal to the BCM which sends a signal to the locks, So, it could be a computer wiring problem, but doubtful. More likely the key pad in the fob is malfunctioning.

 

Those would be my suggestions as well - sometimes the "buttons" on the remote can be way too sensitive when in a pocket or being jostled while on the key ring.

 

X3! The fob keypad needs a good cleaning!

Or replacement!
