: rear doors wont lock when key fob is used

Hey everyone,

Sometimes when I use the remote key fob to lock the truck, my rear doors wont lock but the front ones will. It happens randomly. All the doors will lock if I use the lock/unlock buttons inside the truck.

When I use the key fob and the rear doors don't lock, it will set off the alarm if I open one of the rear doors.

Whats the deal here? Fuse? Relay? I'm confused as to why they lock with the regular switches but not with the remote.

Thanks everyone! Merry Christmas!

Try the electrical section, I think I saw a few posts there about this...

searched.. similar issues but everyone is having issues where they totally wont lock or unlock. My issue is random and only happens when the key fob is used

sounds like the relay is starting to go bad if i remember it is in the drivers door jamb there are 2 of them one for the front doors and on for the back doors,
