    Hi Danny.
    I would go to O'reilly auto parts (not sure about other parts stores), they have a key fob checker, this will let you know if your fob is working or not. They also have replacement cases that you can put your circuit board in if your fob is bad. Hope this helps.

I would suggest visiting the dealer, as that is the only place for a new one. I had the same issue with my fobs. They're not as durable and long lasting as one would think, unfortunately.

SOURCE: power locks for rear doors and hatch not unlocking

you have two relays on the interior fuse block one for locking and one for unlocking. Swap them and see if the problem is now such that they will not lock. If so you have your answer.

SOURCE: the power door locks stopped

Sounds like body computer is malfunctioning or the module that controls the door locks lost it's program.Disconnect the battery for few minutes then reconnect and check.In some cases this resets the system computer and all starts working.But if that does not helps then problem has to be checked with the power door lock system.Either a power door lock actuator or the power door lock switch. Usually the most common problems with power door locks are the actuators. They are small electric motors used to lock and unlock the car doors when activated by a switch or remote. Like any electric motor sooner or later it will fail. Replacing an actuator involves removing the interior door panel for access. Some are part of the door latch and some are independent.
Either way, door lock actuators need to be replaced if they are buzzing, working only in one mode or are not working at all. if the problem is with the door lock actuator or just the switch. If a All the door locks, only work when locking and NONE of them work to unlock, then the switch is most likely the cause.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

How can I figure out why my hatch, power lock buttons, and power mirrors on my 03 Chevy Blazer aren't working? And how can I repair them?

bought it like this.
so fob buttons work, but not hatch.
but lock inside locks fail (elect. buttons)
driver and shotguns side both fail, lock sw?
ext, mirrors dead.
door looks in the service manual has 5 pages of schematics, is well advised to read that first
not scanning the PCM/BCM first is never good.
oK if the speed sensor on the car fails, doors will act up. (for sure if it see car moving and is not)
the radio receiver (fob) works mostly
Fuse MIR /LKS must not be blown door buttons fail
why not check all fuses, save work and not need books to fix it if a fuse blew.?(underhood box)
IP fuse PWR/LKS not blown
the BCM runs the 3 Door lock relays
possibles
Fuse MIR /LKS blown 3amps
this kill local door power to LF and RF door swithes dead. and Rear glass to. the relay board does not fail with fobs. is the key fact.
your post is not clear on all for doors.
or LF an RF door switches. but assumed both are dead, me.
so it is just blown fuse.
we always check fuse first. a 20 cent part.

Back hatch won~t open with remote or inside door locks will open manually nothing stuck or jammed?

Found this wiring diagram for lift gate, if that is what we're talking about? Not only check the fuses, check fuse circuit for voltage. Use a testlite.
