One of the nicest convenience features fitted to Land Rovers since the 1987 Range Rover hit the US shores, was the power door locking system. With the touch of a button you can quickly lock and unlock all of your doors and tailgate. Unfortunately after years of use the system starts to malfunction, turning one of the most convenient features into one of the most frustrating ones. The good news is that the system is very straightforward and you can somewhat easily service the various parts to get everything working again.

The central door locking system is activated from both driver and front passenger doors. A switch/lock actuator is fitted in both front doors.

Front and rear passenger doors can be independently locked or unlocked from inside vehicle but can be overridden by further operation of driver’s door locking control.

Now according to the instruction and repair manuals, failure of one actuator will not affect locking of remaining three doors, tailgate or fuel filler flap. I have found that if one of the front doors is not locking properly, it can effect the operation of the entire locking system, because the front doors control the locking and unlocking of all doors. For instance, if the driver door is not properly locking, you may find this inhibits the other doors from locking and often sends the system into a rapid/erratic locking/unlocking “loop.” But by following the procedures here, you should be able to return all four doors to their original condition.
