Central locking problem

[majormorgan]

The central locking in my 2012 Isuzu D-max crew cab pickup has just stopped working. This weekend the rear doors stopped responding to the button or key and now the front passenger door is doing the same - they all stay permanently locked.

The driver's door is currently working correctly and the lock indicator on the other three doors just makes a weak attempt at moving towards the unlocked position when I try to unlock. The same happens if the unlock button is pressed or the key turned in the driver's door (the only one with a physical keyhole).

Has anyone experienced this before? The fuse is fine and I'm guessing the solenoid/motor in each door won't have simultaneously failed on all three doors. Is there a unit somewhere that sends a signal (or voltage) from the driver's door locking mechanism to all the other doors?

Any help much appreciated!
Thanks...

Aren't all Isuzus under a five year warranty? Book it in at the dealer, surely?

[majormorgan]

Yes you are probably right - I was trying to find some paperwork on what the warranty actually covers.
Also the nearest dealer is a three hour round trip drive there and again to pick it up - plus a courtesy car while they do it. So I thought I'd try and avoid the cost and hassle of a day off work if I can just get a replacement relay or something.

Hi did you get to the bottom of your central locking problem on your D-MAX I have one that is doing the same three doors attempting to unlock only the driver door working as it should.

It just fixed itself after a few days in the end. Sorry I can't give you any more info, hope yours does the same?!

This kind of problem can (sometimes) be caused by a weak or discharged battery (the main battery, not the one in the remote or key), try charging the battery and then see what happens.

Thanks for getting back to me I have just changed the battery as it was completely flat so maybe it just needs some time to sort it’s self out.

Did you ever get to the bottom of this problem? I’m having a similar issue
