Door lock/actuator stuck and door won't open at all!!!

Hi,

The rear passenger door actuator failed recently but was working manually and opened/closed fine. I purchased an OEM door lock actuator for it and was going to change it myself. Unfortunately the door is now locked and I can't unlock it at all. Manually locking/unlocking does nothing and using the inner or outer handle also does nothing. I was able to pull the door panel off from inside the car while locked. I pushed/pulled on the lock/unlock cable as well as the handle unlock cable, outer door lock and still nothing. I even switched the child safety switch button back and forth while trying to manually open the door but didn't work. I can hear the actuator making noises as I pull the handles/cables but it never releases the lock. Just wondering if there is any other way of disengaging this door lock from the inside? The dealer wanted 2 - 2.5 hours of labour at $118/hr just to replace the actuator. If I bring it to them like this it's going to cost a fortune.

Any ideas would be appreciated.

Thanks.

Borrow someone and have them push near handle while you open from inside?

Unfortunately the actual locking mechanism is stuck in a locked state. Pushing from inside, outside or heavy banging on the door near the lock doesn't even get it to budge. I think I'm either going to have to obliterate the actuator and try to move the pieces manually or drill/cut the actual latch from the inside.

Re: Door lock/actuator stuck and door won't open at all!!!

FIXED IT! With the door panel removed I hammered the plastic casing with a long screwdriver/hammer. Ripped almost all of it off piece by piece exposing the internals. It took a while but once in I was able to partially unlock which allowed the door to open about an inch. With further manipulation I was able to push pull some mechanical parts allowing it to unlock all the way. Overall about 2-3 hours in total and no need to have my money ripped from my wallet at the dealer!

Thanks for the suggestions.

Re: Door lock/actuator stuck and door won't open at all!!!

I'm having the exact same problem, after taking out the actuator to examine the inside handle cable for problems unlocking the door.

Now i cant even open the door with the other cable either that was working before. After messing around with the small torx screw on the side of the actuator(turning it left and right), and forgetting to put blue loctite on the torx screws when putting it back in, my door is stuck.

Anyone have info on removing the rear window and window regulator? Its a little different then the front windows, from my experience installing the $5 aftermarket actuator.
Can you tell me where you banged your actuator and did you do any drilling? Thanks.

Cool FX35 All locks moving back and forth by themselves!

Just bought a 2007 FX35 yesterday. I heard clicking noises while sitting inside and from the outside of the vehicle. My husband said "Don't worry about it." (He's in the car business) I go in the garage this morning and hear this constant clicking with the loudest coming from the driver's side rear door. The locks are actually moving on their own back and forth! I tried everything to make it stop. Apparently, this went on all night and killed the battery. Had to disconnect the battery to make the constant clicking stop. Does anyone have this problem or know what to do? THANKS!

I found a company that makes a repair kit for the infiniti door locks . It hooks into the factory system and powers your door locks like new . It is quick and easy to install and cost less than $50 per door and they have a lifetime warranty . took me less than a hour to do and the kit comes with everything you need and has good instructions and photos .
Check them out USActuators.com

Thumbs down fx35 door lock

How hard was it to get the door panel off while the door is lock and can't open. I am having the same problem.

I have the same problem - my mechanic wants $500 for each actuator.
I found a mobile specialist in my area who is much cheaper (he also does windows!) For some reason now the locks are working but my back gate is stuck shut. Would love a new Infiniti... but this is the only problem I have had in 125,000 miles. Kathy

How did you resolve the tailgate lock issue?
I am struggling with same problem; lock is stuck - when button is pushed in the gate latch does NOT release.
The manual emergency lever inside the little window is also NOT releasing the Tailgate.

Any advise from anybody is appreciated.
