When i unlock the srx all the doors open but the hatch stays locked on my 2005.

remove rear panel and check latch for damage or linkage disconnect --also check electrical connections to other components

Please write back with more specific details about the issue. What does not work when the hatch fails to lock? Is the issue the latch and that it does not secure the hatch in the closed position? Is the issue the lock itself? Does the lock engauge or fail to engage when you use the FOB, Key or interior door panel switch? Please write back with what you have noticed. Do you hear the lock/unlock servo "Clicking"? Is the key the issue and if so, what happens?

Possible stuck latch mechanism might need to replace. Send me a picture of the door latch. The one in the door

The lock assy

its alot going on if all that started happening at one time check the bcm. body control module.

Sorry, I don't have the data now..... but.Some hatches have a manual release on the inside. There might be a small plate near the door center that you can remove and open the hatch with a screwdriver.

but...I'm not sure tho about your car.

Hi, my 2005 Cadillac SRX rear hatch is locked and will not unlock, do anyone have an idea or have come across the same proble. Thanks

Same problem. Power liftgate won't work, can't open manualy because it won't unlock. Any solutions?

The lock is stuck in the "locked" position.
When you close the hatch, it is jamming the latch hook into the wrong area.

Manually open the hatch. Unlock the hatch (even tho the hatch is already open). there are two bolts holding the metal "loop", the loop has moved. Adjust the metal loop and close the hatch / lock it, etc.

Check with auto parts stores for an aftermarket latch. Dorman Industries may supply one. If not, try for a salvage yard part.
