When I lock the car with the remote my drivers door lock drops down then immediately pops up and remains unlocked. All other doors operate correctly. Any idea what the problem is? Any hel;p would be much appreciated. Les Howard

If it locks immediately, the locking motor in the drivers door is doing the locking. Sometimes due to the manual locking knob getting stuck. If it locks 5-10 minutes after the door is closed, your remote control needs to be reprogrammed.
Obtain all keys/remote controls. Remove driver's side kick panel/lower 'A' pillar trim. Connect central locking registration connectors (white) - black wire and black/blue wire Fig. 2 . Unlock the vehicle using the key. Program first key/remote control as follows: Press unlock button Fig. 1 , then lock button . The door lock should lock and unlock in sequence confirming programming of first key/remote control. Repeat programming procedure for remaining key(s)/remote control(s). Once the last key/remote control is programmed disconnect central locking registration connectors. Check operation of all programmed keys/remote controls.
The pin solenoid that activates the remote locking is not receiving any electrical signal, it must have been unhooked. This solenoid is right by the filler door, inside the boot. The alarm activates on electrical differences, such as dome light, boot light or filler door electrical demand when it is activated. Hence, the alarm wont trip off if door is opened manually from the outside.
It may be set in the main menu to lock only by the fob. I know on GMC's there are about 7 different locking options. I'm not a specialist in Land Rovers but the cheapest way out is to check all your options on the dash/steering wheel buttons.
you either have a faulty central locking motor or the wiring harness may be damaged.
Remove the door panel and check if you have a live feed to the central locking motor when you use the fob to lock or unlock. If you have power, then it will most likely be the motor that is at fault.
