Hello All,

I have read a large number of threads covered on this board to try and find a solution before posting.

I bought my p38 about 3 weeks ago. Initially the fob would only unlock the car as the button to lock it was totally messed up. I used to lock the car via the key and unlock using the fob and didnt seem to cause any problems starting the car untill a week later i dropped the fob on the floor and it totally stopped working. At this point the car would open using the key but would not start and the engine disabled error would come up. I have tried various times using various techniques to put in the key code which I confirmed is correct without any luck (possibly door latch problem?)

I went down the route of sending my key off to a specialist p38 key programmer (there is only a few in UK that deal with p38 key programming) and received my new key + transponder (fob). The next part is to sync the new key to the vehicle so i can get it running. I tried once again various attempts to use the ignition to sync it as well as the drivers door without any luck. My vehicle is 1998 reg 4.0 HSE.

At the moment all other doors remain locked and only the drivers door opens/closes via the key but the engine disabled error remains. Could this be a case of a BECM lockout? Is there anybody (electrical mechanic) in London that anybody knows who could reset the BECM without having to take it out and send it off somewhere?
What about buying the resync mate from ebay? Would this do the trick?
Any help would be appreciated.

Your key will never sync as it sounds like your latch has failed. See the latch testing stickie above.

Thanks for the response. I will definately check out the latch. Can it be the BECM is in some sort of lockout state because i entered the EKA code incorrectly too many times? ( I dont mean lockout mode on the dash as that goes away after 30min).

The reason i say this is because the key when inserted in the drivers door to unlock only unlocks that door and no other door seems to open. It appears as they are in super lock mode. If i get my hands on nanocom or Faultmate MSV-2 system I will be able to reset the becm / resync it? What about sync mate from ebay - Could that be my solution?

It is indeed possible that the Becm has entered into a locked down state, as it will when it is annoyed enough by someone trying to "Steal it"
If this is the case, you have Marty over on your side of the pond with the gear to unlock it.
With an MSV II or Nanocom, you would be able to read the code from the ECU and and enter it back into the BECM (IF the Becm has not locked down)
If it has locked down, you will not be able to get into the Becm to enter the code.
I have never used a synch mate, but suspect, again, if it is locked down, that will not work either.
Oh, and if the Becm is in any sort of alarmed state, it will not allow keys to be re synched. You need the EKA, and if you have a bad microswitch, you are basically doomed......
"Hello, Marty?"

No. Dealers are absolutely useless when it comes to repairs. They only know how to throw parts at things until eventually it is fixed.

Because you are still seeing this message - AFAIK - this is shows it hasn't locked out, make sure the EKA is correct, its able to be entered (latch) and your EKA sequence is correct for your MY.

Your other doors won't respond until your able to re-sync the fob, if they are truly superlocked you can't open them at all (i.e. from the inside).

When u say key reprogramer u mean a main dealer yes
NO,
I mean someone who can open the Becm up, solder on a couple of wires, and unlock the processor.
IF and I am saying IF the Becm has gone into hard lock down, it is the only way to recover it.
There is nothing wrong with your key as such, it is just not synchronized, and if the car is alarmed, you cannot re synch it.
As stated above, confirm the EKA is being accepted via the side light indicator on the dash, and look up the proper procedure your YM requires

So the fact that i am seeing the code lockout message on the dash when I fail to enter the EKA code means the BECM is still not in a lockout alarmed state? Yes all doors cannot be opened from either inside or outside apart from the drivers door via key blade in the door.

Have you tested the latch? Until you do that there is no point speculating on BECM problems.

Yeah i had taken the whole door card off - i dont know whether its responding the way it is due to becm lockout or if its faulty. It locks fine and key returns to center position.. but when i try to do the unlock it doesnt feel right.

I mean, have you done the tests in this sticky: http://www.rangerovers.net/forum/7-range-rover-mark-ii-p38/131722-info-front-door-latch-tests.html

There's more to it than whether the latch turns, you need ensure the microswitches are all functional.

If you try to enter the EKA and get it wrong, it goes from Engine Immobilised to KeyCode Lockout which will clear after 10 or 30 minutes depending on the year of the car. If you are getting that, the BeCM hasn't locked out, it's doing what it was designed to do to stop people from being able to steal the car. Are you sure you have the correct EKA code? It isn't the 1515 that is often quoted that was used on some US spec cars (others didn't even have it programmed) but will be one that is unique to your car. If it isn't in the owners handbook, then take your V5 into a Land Rover main dealer and they will provide you with a printout showing all the codes for it.

As said though, this assumes that the microswitches in the latch are working and the code is being sent to the BeCM. However, one thought is that if the switch wasn't working at all, then the BeCM wouldn't see a failed attempt so wouldn't go into KeyCode Lockout. Sounds to me more like you are entering the wrong code or entering it incorrectly. Depending on the year you either enter the EKA directly or start with 4 turns to the lock position.

It could be that one of the switches has failed and the BECM is just randomly seeing input from one switch, which it then interprets as someone trying to nick the vehicle.

As you are getting the KEYCODE LOCKOUT message, the BECM isn't in alarm lockout yet, so it should still accept the EKA. Do the tests in the document attached to my door latch sticky post. If one of the switches fails, then it's time for a replacement latch. I do refurbished units at about half the cost of a brand new one... though I am not home for another week or so before I could send one off unfortunately.

Once you know that the latch is working (or not and you get it replaced) as GilbertD mentions - get the EKA code that the dealer has on file. There should be no charge for this, usually just proof of ownership is required.

Once you know the correct EKA and know the latch is good, then have another go. There could be a slim chance that the BECM has been previously changed and the EKA is different to what the dealer has on file - but even then, I can retrieve what is stored in the BECM with the programming equipment I have - should it come to that (which is unlikely!)
