Central Locking broke

N5Fav · Oct 9, 2014

Bah.
Just when I think I'm getting on top of things P38 wise.

Went to it this morning and it didn't unlock on the fob, let myself in with the key, turned on the ignition and it's immobilised and wont' de-immobilise by pressing either of the fob buttons.

Checked the fob operation on and it is sending an RF signal, so now to decide where to start the checking process. Dig out the Nanocom again.....

Just as well it's not my only transport, but it is supposed to be the workhorse

Old type RF receiver burnt the locks or duff fob, how do you know the fob is sending?

How did you let yourself in with the key? Did you use the eka code? You'll need to follow the handbook instruction to re-mobilise.
Check the state of your battery as well.

+1 how did you check its transmitting?

1. I let myself in by using the key blade in the door lock.

2. I know the key is transmitting because I have a sealey key fob tester - it has an LED which indicates that either a RF or IR signal is being sent.

Now this seems strange - but then we are talking Range Rover.
I plugged the Nanocom in and started having a look around. In settings, I had to change it from GEMS to late EDC, from LHD to RHD, from Manual to Auto. I had to remind it that actually it doesn't have a sunroof.

And behold, everything started to function again - central locking, immobilisor, and it started up

I haven't had any flat battery issues, and it has recently performed quite well towing a caravan up to the Lake District and back with no issues.

Low battery voltage, dodgy alternator, wet carpets or bad connections, even a dodgy underbonnet fuse box.

+1. Low voltage throws up all sorts of gremlins. Rangeys like a big healthy battery. Even if it hasn't gone flat before, worth checking the condition and sorting before winter.

OK, will test the battery tomorrow.

Carpets are all dry by the way

Rick-the-Pick · Oct 10, 2014

It sounds like the becm has been replaced sometime in the past.
It may of reverted back to it's original settings. They can do this occasionaly, but it's not common.

After all I'd said, it was a bit slow starting the other morning. So i got a new battery lined up to fit. Took the battery cover off and tested the battery = good.

But then I noticed the negative bolt had become loose!

So good call from Datatek and Kevwill

Thanks.

PS just done two 5 hour round trips up and down the M40 twice the last couple of days.
