I've got a dead Range Rover (1995) thanks to the dreaded key code lockout. Unfortunately the central locking isn't working so I can't enter the EKA. The problem first manifested itself as the passenger door not unlocking on the key. The other doors all unlocked. However the rear doors are now super locked. The front door and tailgate both unlock when I use the key. I can also hear a click coming from the drivers rear door when I lock it with the key.

I've tested both front door latches per Martyuk's excellent guide and everything checks out. I've also replaced the door outstations just in case. Still nothing. A couple of months ago I pulled the trouble codes using my Lynx Diagnostics and it did show no coms with the door outstation and no coms with the centre console. My best guess is that there is a bad connection between the BECM and the front passenger door outstation. Is there any particularly likely spot for the loom to fail?

Also, is there anyone nearby to South Somerset who can unlock the alarm? Apparently the Faultmate MSV-2 can disarm the alarm, but only if I buy the Multi-Vehicle software module which puts the price at somewhere around £900!

Does anything else work in the driver's door?
Honestly, unless you can read the wiring diagrams in RAVE you're going to need Marty to point you at the next steps for diagnostics.

Everything works in the driver's door. Window and mirror work on passenger door but central locking doesn't.

Keycode Lockout will usually go away after 10 minutes on an earlier car and you can't enter the EKA code while it is displayed. If it doesn't go out to be replaced with Engine Immobilised, press remote or enter code after 10 minutes, that means the BeCM has gone into lockout so sending it to Marty to be unlocked is your only option.

If you have windows and mirrors working in both of the front doors, then there isn't a communication problem between the BECM and the outstations or the centre console switchpack, as they all communicate on a serial link to/from the BECM.

The central locking for the front doors are controlled by the outstation, via the serial link from the BECM, so if this is working for the windows/mirrors, then that isn't your problem.

It sounds like the BECM has gone into lockout mode - whether you can still get it open with the EKA or not will depend on if it's in a complete alarm lockout or just an EKA lockout.

If you have KEYCODE LOCKOUT on the dash then leave it alone with the battery connected until it disappears from the dash. Then you can try putting the EKA in. Note that the early ones DON'T require 4x turns to lock to begin putting the EKA in, like the later ones. I think the drivers door just needs to be locked, and then you start by turning to unlock for the number of turns of the first digit. If it doesn't work, and you know that the microswitches in the latch are all functioning as they should, then chances are it has gone into an alarm lockout, which as you have found needs the Faultmate MSV with BECM CPU module to reset the alarm lockout.

I have the equipment to connect to the BECM and reset the alarm lockout. All of the details are on my website - I try to do it for a reasonable price, as I do P38 work as a hooby outside of my normal job. That being said, I am about this week if you need it looked at, but start getting busy and away with work again next week - and then I'm off until the end of December, so won't be doing much P38 wise except on forums until I get back!

Hope this helps,
Marty

EDIT: PS - the passenger door and rear doors won't unlock on the central locking until it's out of the lockout situation (whether it need the EKA entered, or hooked up on the bench). Once it's back in a happy place then the rear doors should automatically unlock from their superlocked state, and the passenger door will start working on the central locking again. If the passenger door still doesn't unlock/lock on the central locking once whatever lockout the BECM is currently in, then chances are the Central Locking Motor in the passenger door latch has failed and not activating to lock/unlock the door.

I've replaced the passenger door latch as I assumed that was the source of the original problem, but I didn't know that key code lockout disabled central locking. I'll let it sit and give it a try. If it doesn't work, would it be possible for me to bring the BECM up to you tomorrow?

Yes, the central locking is all controlled by the BECM, and if it goes into a lockout situation where it expects the EKA to be put in, then the key in the drivers door will ONLY operate the drivers door until the EKA lockout is resolved, and then the alarm will disarm, the immobiliser will switch off, and the other doors will all unlock and respond to the key in the drivers door again, or to the remote when it's resynced.

If you have no luck, then yes, I am about at home tomorrow and will have time to hook it up for you if you want to bring it up, no problem there.

All sorted now. Just needed to wait for the alarm to come out of the advanced lockout state. Thanks for all your advice.

How do you mean the advanced lockout state?

I mean out of the key-code-lockout-rear-doors-superlocked-damn-these-cars-can-be-frustrating state.

The rear doors won't unlock themselves until the EKA is entered, or the BECM otherwise disarmed. If it's a 1995, I'd guess its unlikely to have a recent enough software version to allow the EKA to be entered via a Nanocom, so you'd need to do it with the key in the drivers door, assuming the switches in that door all work properly.

My problem was that I didn't realize that when it is in keycode lockout, turning the key doesn't unlock any of the doors other than the drivers door. So even though I'd changed the faulty latch in the passenger door I was still under the impression that something was wrong as the key wouldn't operate that latch until the vehicle was allowed to come out of the keycode lockout.

So is it out of KEYCODE lockout now, and are you able to get the EKA entered and get it to start?

Yes, I hooked up the battery yesterday morning, left it and came back and entered the EKA. No indication it was working (no sidemarkers flashing) until I unlocked for the last time and the rear doors unlocked.

That's a good sound, isn't it :)

Sidemarkers don't always flash, some do, some don't. But if you look inside the car, you'll see that the sidelamp warning light flashes.

So... is it now willing to start?

Starts... and even drives. Now to sort out some niggles before the MOT and eight months after I started my top end rebuild (famous last words... "This should only take a few weeks dear.") I'll finally have a useable Range Rover again.

Time to make a donation to this forum? ;)

(This should only take a few weeks dear.")

I remember saying something similar the first time I did a set of heads,( on a p38 ) took me 3 days to get the heat shields off.
Doesn't matter how long it takes, that feeling of you've done it, and saved a grand makes it worth it
