It sounds like the drivers door latch has failed. So when you unlock the door manually, the key switch isn't triggered, so it thinks its being stolen, immobilises itself and sets the alarm off.

The only real way of fixing it is to replace the door latch. I don't know how easy that will be to do where it is. Are you able to leave it in the parking whilst a latch is found?

Otherwise it might be a case of having to get it recovered (somehow) to where it can be worked on.

Depending on how technical you are, it could be possible to pull the door card off and 'mimic' the door latch key switch whilst operating the remote to fool it onto thonong the key is in the lock whilst you try to sync the remote. But it might not want to do it whilst alarmed..

Either way the door card needs to come off, I don't know the reaction if you pull the battery to work on it...

Yes, it can be towed in neutral. There is usually a fuse you can put into slot 11 to put the transfer case into neutral for towing. You put a 5A fuse in, turn ignition on, and it should move the transfer case into neutral. Turn ignition off again, and it will stay in neutral until the fuse is removed and ignition is cycled again.

However, I'm not 100% sure if this still works again, as the vehicle is alarmed/ immobilised. If it's only a short tow, then it should be fine to just put the transmission in neutral and do it that way.

Best of luck!

You'll have to pop the door card off at some point - you might be lucky and find there's just a damaged wire in the loom, as they sometimes get swiped by the window mechanism. But of it locked OK, then it does sound like a failed latch.

Good to hear!

So have you got it out of the car park and back home?

Now is the time to start doing some tests on the door latch and the micro switches inside it to see what has failed.

http://www.p38rangerover.com/central-locking/door-lock-actuator.html

That site has a load of information on testing the door latches, that page is the first page about the actual door latches, but on the menu on the left hand side it has individual tests for each or the internal micro switches in the latch.

I personally unplug the outstation when doing the tests (with the vehicle unlocked) as I've found that when the latch is unplugged (with outstation connected), the vehicle then locks itself. Its not a problem, as it re-unlocks when latch plugged in again, but if you're having lockout and alarm issues, then unplugging the outstation temporarily will stop the 'lock' command getting to the BECM.

If the latch fails any of the tests, then it's time to find a replacement.

If the latch passes all the tests, the try each one also with wiggling the handles, sill lock, and key in the lock in case there's something loose in the latch causing an intermittent problem.

If the latch still passes, then the next place I would check is in the gap at the door hinge where the cables go into the vehicle body (in the rubber cable tube) as there is a connector in there which goes green and can produce issues with the outstation communication to the BECM. Though if this was the issue, I would expect the mirror to stop working too, as I think (from memory) those commands are sent via the outstation aswell.

Hope this helps,

Marty

I would definitely be looking at it sooner rather than later..

Take this as a 'lucky break' and make sure your door latches are OK, and the wiring is good. You had a stroke of luck that it decided to work again. There are plenty of threads on here about people who have not been so fortunate, because they haven't fixed the small problem when they had the chance, which has then turned into a bigger problem.

If your key didn't unlock/turn the alarm and immobiliser off when used in the door then SOMETHING isn't working right. maybe it is a sticky micro switch, or a chafed wire - but the outcome of this for most owners who haven't taken the warning signs and delved into it a bit more and fixed the issue have usually ended up with a completely locked BECM, which then requires removing from the vehicle to be sent away for specialist unlocking.

My words of advice... I personally wouldn't be using the vehicle until I'd got it sorted for fear if it happening again, further from home or in an even more remote/difficult area...

Hey Marty,
I have had similar issues. My keyfob is damaged and I am attempting to "repair it" by switching out the internal "card" with another keyfob in working order. Do you think this might provide a solution? Also, I apparently have a bad rhd latch as it is increasingly difficult to open. Is that the type of thing a hard working amateur might repair himself? Thanks for any input.

Hi

The latch replacement is a fairly easy replacement for a DIYer, if not a bit fiddy.

There are 3 rods and the internal pull handle wire to disconnect which require a bit of twisting and wiggling inside the door, and reattaching them all inside the door can be a touch tricky, I was cursing a bit the first time I did one, but you get the knack of it pretty quickly!

You need a torx head bit to undo the latch itself from the door, but that's about the only out of the ordinary tool needed.

Hope this helps,

Marty
