Disco 2 TD5 Jammed Tailgate lock

battenberg · Sep 21, 2011

I put a replacement door lock in the tailgate today, shut the door and now it wont open...

The button comes up on key press but the mechanisim seems like it's jammed. I got the door card off from the inside and can get to the levers of the lock but I still cant get the door open, no matter how much wiggling the levers and shoving the door.

Short of taking a plasma cutter and cutting the bloody door out... anyone got any bright ideas on how to get the door open with a lock that the mechanisim is jammed. You can only remove the lock with the door open and you can only get to the hinges with the door open??

Stuck!

I suppose that was done on purpose

don't know if the D2 uses a different mechanism, on my D1 I always had to pry the rear door upwards with some large screwdriver before I could open it, until some kind soul adjusted the fixed part of the lock (but that also needs the door to be open)

My rear door lock stuck several times last winter and did as you did ,took off card as I couldn't open from the key or the inside lever but the reason was the lever on the outside needed loosening up with some silicon oil and a straw ,then operating it many times I freed it up and it opened..I think rainwater from the gutter (which was broken slightly) caused water to seep in to that area..worth a try...so in my case,not the lock but the lever itself .shoot some lubricant up under the black cover at the right hand side

Discomite, I get exactly what you are saying, because that happened to me before, but I disconnected the rod from the outside handle simply to knock it out of the equation, the lever that it acts upon is the one that I'm wiggling from the inside...But no Joy!

Hi I had the same problem last year, you can remove the green oval badge on the outside of the handle/locking mechanism and have a fiddle about, with mine it was the release rod that had fallen off due to having to slam the door due to dropped hinges, don't know if you've tried this but hope it helps

It was the CHILD LOCK that got itself stuck in an intermediate position!

Solution:

I think I was having the same problems as the original poster, and angling a screwdriver (from the inside of the car) past the door weather seal bulb to push the child lock back all the way up into the unlocked position resulted in a loud CLICK and then the door worked perfectly for a few cycles before getting stuck again (requiring the same fix). Even though the child lock switch looks 'up', it isn't all the way up and only forcing it up with a screwdriver push results in it unlocking. When the child lock is stuck in an intermediate position, neither the inside nor outside handles work. I'll be replacing my door lock actuator, as it seems to keep getting itself into this intermediate position.

Problem:

My Land Rover Discovery 2 tailgate / trunk / rear door is stuck shut. All handles feel like they function properly and the door lock actuator sounds normal in each key fob unlock, lock, and superlock. The little door lock tab indicator on the inside of the trunk door pops both up and down as it should when actuated via key fob, and it pops up when the door is locked then the inner door handle is pulled. So all this looks and sounds normal. But the door is totally stuck shut! I've removed the interior trunk door trim to view the actuator and it looks fine and operates fine. But door won't open. Help!
This is *not* the classic Disco II rusty outdoor handle fixed by WD40 issue. The outer and inner door handles pull and spring return just fine.

Thanks to:

LandRoverForums member Rovin4Life who described this phenomenon
Landyzone forum member johnboy02 who also had a good story about it
LandRoversOnly forum member Zershin who also followed up to say what it was

Same issue (suspected):

See here
unlocking the tailgate door childlock from within. you can go for it blind, but i found it to be easier to just pull the weather seal bulb to improve visibility

improved visibility with weather seal bulb removed

diagram of what you're trying to do

you can even see the child lock switch indent in the foam

the goal is to push this switch up to the unlock position. i know it already looks like it's up, and it won't shift much... but it'll shift a bit, and give you a big loud satisfying click when it goes.

Thanks! I got my tailgate door opened thanks to you!!! I registered here just to say thanks!!!

After removing the actuator i could see that the problem was a small plastic knob where the child lock pivots. It should be stuck in the metal casing but it broke and the child lock was behaving badly.

Instead of buying a new lock i drilled the plastic axis, put a thread in the metal casing and replaced it with a 5mm bolt with the head filed down for clearance.

Its been a few days and it's working great.

Sorry i forgot to make some pictures.
