Land Rover Repair: 95 RR Clasic LWB tone alarm, range rover classic, centre position

Question
My 95 Range Rover Classic has a new quirk that is getting more frequent.
After I have driven over 15min or so a continuous tone comes on. The tone
comes from the same place as the "key left in the ignition" tone except it is
consatant. When I stop and try to remove the key it is locked in the ignition.
The key will release after 15 min or so. I do know that the ignition switch is
not the problem(I just replaced the entier assembly to no avail). Any ideas on
where to start with diagnosong this?

Answer
Hi ER,

have you tried to resync your alarm system?  

If you are in the UK, refer to your owners manual and try the EKA (emergency key access) procedure.  Perhaps it will correct itself.

If you are in N.America, there is an unofficial procedure (LR dealers only) that has worked for some Rangie owners:

Using just your key, procedure was done on drivers door -

Unlock once
lock 5 times,
unlock once,
and then lock 5 times.

You could also try a remotes resync:

"Close the car.  Insert the new remote in the drivers side lock pressing and holding the button with the lock symbol.  Turn the key to the right as if locking, still holding the lock button down.  Hold in this position for 3 seconds. Turn back to the centre position and pull the key out - STILL HOLDING THE KEY BUTTON.  Once the key is out release the lock button."

I hope one of these helps.  

Try the resync procedure first.  If it does not work, try either the UK EKA (if you live outside N.America) or the above variation if you are here in N.America.

Let me know if this does not work.  IF so, I'll try to find some other methods.  Otherwise, it may be a door sensor or the security ECU itself.
