Programming keys for your Land Rover
Most high end cars have two parts to their keys. There is a mechanical key blade that physically unlocks a mechanism, and there is an invisible electronic component that talks to the security system in the car to authorize starting.
That’s why you can’t copy keys at a locksmith anymore . . . they can duplicate the mechanical part, but without the electronics the key is useless. Even worse, if the lock turns without the electronic authorization, the alarm may go off and the car may enter a locked-down state that necessitates a tow to the repair shop.
Programming or coding keys for Range Rover 4.0 and 4.6 - 1995-2001
The pushbutton keys are numbered Key 1 through Key 4. When ordering a key, you specify the number. You can only have one of each number. So for example, if you have a Key 2, and you order a second Key 2, only one of those keys will work the remote locking system.
The keys are identified by stickers which unfortunately wear off with time. The result: you kind of take your chance on key numbers when ordering new keys, unless you have the foresight to write your numbers in your owner’s book.
Synchronization of keys on these models is pretty easy. Put the key in the driver door. Turn it to lock while pressing the lock pushbutton. Hold for 5 seconds. Turn to unlock, press unlock and hold 5 seconds.
At that point, the vehicle should lock and unlock via pushbutton. If you cannot synchronize any keys the switches in the door latch may be bad, and I suggest you attend to that right away as the car will be stranded is security sync is lost.
Programming or coding keys for Range Rover – 2002 to 2005 and BMW 7 Series 1995 to 2001
This version of Range Rover was designed while BMW owned Rover, so the key programming is shared with the big Beemers . . .
1 Make sure the vehicle is unlocked and the doors are closed with windows down (so you can’t lock yourself out by mistake)
2 Put one of the keys in the ignition and turn it to the first click and then back off within five seconds to put the car into initialization mode. From this point, you must continue key programming within 30 seconds or the system times out . . .
3 Remove the key from the ignition
4 Press and hold unlock button for up to 15 seconds. While doing this, press the lock button three times within 10 seconds.
5 Release both buttons
6 If you did this right the car will answer you by locking and then unlocking the vehicle. If this does not happen, repeat from step 4
7 Repeat steps 4 and 5 with all the other keys for the vehicle (maximum of 4)
The pushbutton keys in Discovery II models can only be coded by a shop with the Autologic, T4, or IDS diagnostic systems.
