Thread: Rear door not unlocking.....

I had the same issue with my MY2012 90. I thought it was dust in the lock so took the lock out and cleaned it and lubricated with Silicon lubricant and it OK for a short time but then started playing up again. It deteriorated to a stage where the key wouldn't unlock the door either.

Replaced under warranty and no problems since.

I'm currently working with the dealer on trying to find out what's wrong with the central locking on my 2014 110. Sometimes it sounds like it's dying but we can't work out which sensor it is. They're considering replacing the rear sensors as they appear to be the main problem.

Take yours in to your dealer and they should replace under warranty.

I also had the same issue with my 2014 110 rear door lock. Ended up having the actuator replaced under warranty about 5 months ago and no issues since.

The driver's side rear door on our Defender doesn't lock/unlock with the remote either. Replacing the actuator made no difference. Must be electrical somewhere I guess. Will be looked at again at the next service.


Have you lubricated your rear door lock? If it's locking then it must be receiving a signal.

It lock fine.

But it doesn't electronically unlock. And to do it with the key you have to hold the handle up, and you can feel a clunk with the key as it does unlock. I will have to book in for replacement under warranty I think.
They can do it at the same time as they are doing the rear main. :-(


Thanks gents. :-)


Cheers,

Get them to check the wiring where it goes through the convoluted rubber conduit at the b pillar. They pinch and eventually break the wires. Have repaired heaps of them.

Any one else have this problem?
Tyre issue perhaps? Just as well I haven't been over any serious corrugations.......


I am going to need to take it in for warranty work soon anyway.... There's engine oil leaking (weeping) from the bell housing, so the rear main is leaking..... And some other minor stuff. So I want to get everything done at once......


I will have to take my computer out though, and put the original back in..... :-(

What a drab run in that will be..... The 170 remap is to live for..... :-)

Phill,
My 2013 Defender 110 has gone out in sympathy.
Back door lock would not unlock after I blew air into it to remove dust. Was working fine prior to that. Anyway put some lubricant in there and once again blew it around with compressed air and it is working again. Don't know how long that will last before dirt gets in there again.
My rear main seal is weeping as well, just very slightly at only 19,000km. My other Defender leaked and so did my 2012 Mazda BT50 3.2, all about the same time. Not too confident in the seals!

4Wheeler,

I can't believe what I am hearing here.... Admitting to owning a Mazda.... The shame of it....
But..... I suppose.... You have seen the error of your ways. And, come back to the fold. Hallelujah Brother! You've seen the light.

Perhaps the weaping rear main is problematic with the puma series engine. And there I was thinking that, with my luck, I copped a dud. My leak was spotted at the 20K service. It's due now for it's 40K, so I get it all fixed up soon. I will ring around to check prices on the service though. It's marvelous how much it can vary, according to company and who you talk to.

Tomorrow I will spray some gun oil into the lock. I don't know how much good it will do. As it's not catching when you initially turn the key, as it would be for the pins and barrel. Instead it's at about 45? that it catches and then feels like it manages to slip past what ever it is catching on. It certainly won't get past what ever it is without the handle held up. Holding the handle up wasn't required at the start, but it is now.


Cheers,

Phill.
