My 2009 Nissan Hatchback trunk will not unlock or open even though all the other doors unlock with the remote key. I have checked the fuses and am wondering if I need to replace the door lock actuator. If so where it is located and is it easy to replace? Has anyone had any success with this?

Try to look for a key hole around number plate or anywhere else, if there's non, bad luck

Maybe it's just a fuse? My trunk wouldn't open or my gas tank door, all it was was the fuse but it took me a month lol

Do any of the other buttons on the remote work, like the horn or trunk-open buttons? If they do, then you might have a blown fuse or relay switch for the specific problem. On my Grand Am, there are relays for "Door Lock", "Door Unlock" and "Driver Door Unlock".

Typical failure with the Nissan Versa,You need to find a auto electrician that is willing to go to the passenger side where the lock and unlock for the trunk module is located and and jump the wire together,This solves the problem forever, other than that the module needs to be replaced and yes you better make it a hobby it always fails

there is a release threw the trunk check the latch after you open it

Either via an actual theft attempt or you (or someone with your keys) not realizing that you/they actually armed the vehicle and opened the door or trunk afterwards.

Essentially this sounds like the vehicle was entered after being armed and the proper precedures not met to reset it.

The car may just need to be locked from the outside with the key (not the remote or keyless entry) while the doors are closed and windows are up, and then also unlocked with the key...

However it sounds as though you have perhaps driven it since then. If this is the case

You may want to check all your fuses and replace the ones affected by the anti theft system.
Security - Pwr Locks - Horn - Pwr Trunk Release _ Int Lights - and maybe The Emergency Flasher as well.

Be sure and check under the Dash, Hood and under the Back seat.

Cadillac recommends after a theft attempt, the vehicle may need to be serviced. So I recommend going through the fuses first, even replacing the battery in your remote fob and then if the problems still persist. have the vehicle serviced.

Good Luck and Happy Motoring

Respectfully

you may have to replace the remotes and then have them reprogramed for the car because they do go bad but if there is an autozone near you they will test the remotes for free

try getting some dry lubricant and applying it in the lock this usually works well. cold weather usually makes the problem worse.
