Automatic locks not engaging

Lately, when I hit my locks, either with the keyless or on my door panel, the 2 front doors and the rear door won't lock/open/etc. It is very random when it does it and what door it choses to either open or lock. Sometimes it is just fine too. The battery in my keyless is fine. Any advice?? Thanks.

Your dock lock actuators are most likely bad, I was having the same problem with my driver side door. You will need to remove door paneling and door module to get to actuator, its good one hour job, make sure all the necessary tools handy. The door actuator I bought cost $90.
