Default 03 Suburban locks

While off, idling, or driving the locks will lock and unlock when ever they want. Changed the relay but still does the same thing. Any help would be greatly appreciated.

You may have issues with your key fob. Take the battery out of it and see what happens.

Thank you we have tried taking the fob batteries out and replacing them and it still locks and unlocks with the batteries out of the fobs.

2x, do the door switch's one at a time so you know which one is acting up. Those lock switch's are powered up all the time key on or off.
