My car frequently goes crazy and locks and unlocks itself rapidly and I have to pull the lock fuse, I reinstall it and it's alright for awhile(a day tops) and then it goes crazy again. When it's doing this I can hear a clicking under my dash like a relay maybe. It's locked my keys in the car 3 times now.

 

Anybody?

 

Might have some water leakage or a short in your car or possibly even some condensation in your key fob.
