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.

Bad power lock in door.

If you hit the unlock button in the door 2 times, it should unlock the tailgate. Otherwise you may have to go back to the dealership and have them program a new remote for you. If the battery in your remote went dead, it may work again by replacing the battery.

There is no keyhole and switch on the rear hatch in Jeep liberty.
You can control the hatch by remote key and window/door switch on the driver seat side.
I don't know why they make like this, it's inconvenience.

it programmable.
and new, car its a double click to unlock all.
did you read the manual yet, its all there. every word , in the glove box.

here it is , get it and keep it , on hand.

read locks section. and how to program it.
if its not programming then its bad.
check fuses first.

Mine did this too....the latch kept getting stuck. If you put the key in the ignition and unlock the power doors, pull on the gate door (don't open it, just enough to release the latch), and it should come out so the hatch will latch.

This will help.

Thanks.

Sounds like you have a key without the chip in it. Replacement keys without the chip will only unlock the doors and will activate the theft alarm when you start the vehicle.

Your security system could have a problem, replace battery in keyless remote. If not helping you may have to take it somewhere and have security system checked
