Manually unlock Trailblazer lift gate hatch Trailblazer SS LS2 Envoy

you'd better call a mechanic in your place.

had this problem myself.... you gotta go in through the back and take the plastic/vinal cover off the rear door and look for the lock from the inside..... unlock it .... open the door and then you can repair and lube the mechanism while standing outside like a human being. its not very hard to do.. just take your time and don't force anything.

the switch is bad on the rear hatch cylinder

this might sound silly but, have you tried to open it with the key? sounds like the lock/unlock mechanism is stuck or broken.

Fixed this last week in my Cherokee Classic. I started by releasing the hatch catch from the the interior by manually placing a flat screwdriver (something flat) under the catch, pulling the door inward, and letting the hatch open. From here unscrew all screws around the interior panel including the 2 screws under the rubber caps that mount the interior pull handle. Then carefully pull the panel, one section at a time, (carefully...this plastic is cheap) until all panel clips are free and the panel is removed. At this point you will see the inner mechanics of your door latch. Pushing your key fob lock you will see what you have been hearing, and lifting the outside handle you will see what it is supposed to be doing. As you sit in the interior of the car and face the inside of the hatch door, on the drivers side of the latch mechanism you will see a small threaded rod that is attached to the latch mechanism and the catch on the bottom of the door. This threaded rod must be adjusted/returned to the proper setting in order to lift the door catch. This entire mechanism is so cheaply made that you could have something broken in it also....but after finding the aforementioned adjustment mechanism, I realized that it would not take much for this part to self destruct. Hope this helps!

Hi there,
Try adding a little WD40 to the lock itself. Use your hands to lock and unlock it to get the oil to spread. Put a little oil on the key, then put it into the lock. Use your hand and key to move it through the lock and unlock stages. I hope that this is some help to you. Good luck and let me know. Have a great night.~MWD
