door lock problem

Door lock mech's have gone out on all but RF. I replaced the LF. The control on the arm rest works fine on both front doors.The two front doors lock and unlock with no problem. When using the key remote; however, the door will unlock but when I press lock, I get a long beep and nothing happens. Any thoughts would be appreciated. Thanks. Tony

 

the long beep usually happens if a door is open when youre trying to lock the doors, which leads me to believe that theres a sensor issue assuming a door is open

 

All doors are closed. Also when each door is opened, the red open door symbol lights up on the dash display. Where are the sensors? Thanks.

 

i think they're built into the rubber spring type sensor that activates the lights found on the jamb

 

Rear hatch sensor must be intermittent. When I slammed it, everything started working as it should. Thanks Ethan.

 

glad to help!
