Electronic lock on rear hatch of 2002 ford escape will not open

Won't open with the key ? Do all the other doors lock an unlock ? You have to understand the electronics involved , you have a remote keyless entry module an all switches are an input to the (RKEM) , an from the voltage input it knows what door to open or unlock or lock . First you would need a wiring diagram to test the circuit an you need to pull the inside panel off the rear hatch to get at the motor to see if the power is getting to it. Can be a very time consuming job. Here check out this video ,it's not the same vehicle as yours but it will give you an idea of what's involved . 2008 2012 Ford Escape Liftgate Latch Won Open Access Diagnosis Repair

Bad lock actuator: (NOTE: If your hatch is locked)
First remove rear panel- pull the plastic panel at the top center, until (2)clips pop off, then pop (2) more clips at the mid-center. Stick your arm down until you reach the lock, with your fingers, feel for the squishy plastic( inside is the bar that goes up to unlock), it is attached to the lever to unlock. Pull up the lever until you can open the hatch. There are four more clips at the top sides and middle sides, and four plastic screws at the bottom which is only accessible when the hatch is opened.
The lock is only sold as an assembly at $100.

This will help.

Thanks.

A fuse does not operate the rear hatch, neither does the remote, the remote only unlocks the mechanism, so you can use the handle to open it. The only way to open the hatch if it will not open is to drill out the lock and ruin the linkage, in order to manually move the linkage.

read door lock actuator gone bad

I had the same problem on my 2002 Escape. Ended up taking it to the dealer and they replaced the Lift Gate Lock Actuator - cost us about $310 (parts and labor). Part #1C3F-18C815-AB

The liftgate consists of the following components:

• liftgate door lock actuator
• liftgate lock cylinder (if equipped)
• liftgate window glass
• liftgate window latch/ajar switch
• liftgate window glass release handle
• liftgate latch remote control which consists of the following component:
  • liftgate release handle
• liftgate latch, which consist of the following component:
  • liftgate latch door ajar switch

1. Remove the screws and the liftgate latch actuator

It is the rear door lock actuator. It controls the window and hatch lock. Unfortunately the actruator is a dealer item and Ford does not sell the actuator by itself. You have to putchase the entire latch assembly whic comes with the actuator. It will run you about $150 for parts.

i would suggest you to change that part fully and not wait till it becomes useless.

1) Unlock all doors from driver's door while it is open. The driver's door is the only door to remain open during this process! 2) Turn the key from OFF to RUN 8 times within 10 seconds, with the eighth turn ending in RUN. All the doors will lock and unlock if program is successful. 3) Turn key OFF and remove key from ignition. Within 20 seconds, press any button on the remote. (Press sliding door or rear hatch and it will open!) 4) If door locks do not respond, wait several seconds and press button again. If doors still fail to respond, try repeating steps (1-3).
