Rear door not unlocking on central locking

As per the title, one of my back doors is not unlocking under central.locking. Before I start ripping stuff apart, anyone have any suggestions ?

Thanks

faulty solenoid in lock assembly, replace lock assembly, budget for around £75 main dealer or £50 ebay, plus an hour or so if you've not done it before.

good luck

If you can here the CL solenoid operating on the door in question then it's possible that this little lever has seized preventing the solenoid decoupling /coupling the actual mechanical lock .
You'll have to remove the door card and gety your hand up between the inner door skin and the solenoid shown. Spray copious amounts of three in one oil in and around it and then free it by hand until it operates.
Alternativly detach the two rods from the green couplers ,the multi plug and unscrew the three torx screws on the solenoid body and remove it on to bench
I had the same problem and found that this was the source of it.
Good luck.

Thanks for that Steely. Yes I can feel the solenoid popping so I guess it's off with the lock tomorrow.

Ocassonally, my passenger side rear door acts as if the 'childlock' is engaged, but won't even open from the outside either.

Last time it did it, I gently hit the door skin in the area of the lock mechanism (from the outside of the vehicle) with the flat of my hand, and it opened and has continued to work normally so far...

On a previous ocassion, when it stopped working, I found by applying a little forward pressure on the door handle assembly complete (inside the car that is) then it started working.

Obviously I suspect a mechanical problem rather than an electrical one.

Any suggestions?

Ok had a closer look today. It will lock on CL, but not unlock.

Tried to take the door card off but the plastic plugs holding it on feel like they are glued in ! Started to break the door card so decided to leave it.

Any further ideas ?

Well,

Its just like OP says - the solonoid is faulty.. Youll need to buy a new/2nd hand one and youll have to take the door card off come hell or high water.. Its a common problem

My freeleander did it on the drivers front door to start with, then the passenger front door went.. they all locked no problem, but when i pessed the unlock button, only my rear doors and boot opened..i bought a solonoid for each door off ebay for about £33 each, then took about 45 mins per side to fit them (and grated the skin off my knuckles!)

There are no other suggestions really... as for your door card, mine popped off easy enough.. you sure that youve undone all he screws and popped all the rivets??

At the end of the day, it depends on how much you want the door to unlock.. if you can put up with reaching over from inside to unlock it, leave it and spare your door card (if it really is that stuck).. if its something you really want sorted, then you'll have to get the door card off, even if it means breaking it..

Screws no problem, but the rivets I assume POP out when you pull the door card ? This was my problem though, I had great difficulty popping them out
