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.

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.

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.

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

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

You bought a P38 without possessing any mechanical skills? Something tells me this thread is going to be EPIC!

I rebuilt the top end because it was pressurizing the cooling system and it had two flat cam lobes. I think the cam lobes were on their way out since I bought it as it always felt pretty sluggish (although it's a pretty big vehicle for 4.0L to haul around). I've fitted the H180 cam from Turner Engineering. The gas-flowed heads were a lucky find. A chap over in Devon listed them on eBay for £250 BIN or Best Offer. I offered him £200 and he came back saying someone up north had offered him £225 and if I matched that price they were mine if I came and collected him. I don't think they were on eBay for more than a couple of hours.

Unfortunately I haven't had it running much since the rebuild thanks to the current electrical malarky, but it's feeling a lot peppier now.

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?

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

I've posted up a thread in the Electrickery section that explains where I'm at. I've tested both front latches and they're both fine. It appears I've got a bad connection between the BECM and the NSF Door outstation.

Unfortunately the passenger front door lock quit working some time ago so that is why I can't enter the EKA. You're right that the Nanocom won't work on mine. Apparently the Faultmate MSV-2 can be used to disarm it, but only if I buy the multi-vehicle software module.

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!

My name's Drew and I own a 1995 base model Range Rover 4.0 who I've named Calamity Jane. You can guess how she got that name. She's currently dead thanks to the dreaded key code lockout and non-functioning central locking. This is doubly frustrating as I just swapped in a high lift cam and some Turner gas-flowed cylinder heads. I'm in South Somerset.
