Hi my central locking is playing up. Passenger door is locked closed and does not unlock either with remote key or pulling the button up. Can anyone advise how to get at the actuator without damaging the door panel? It doesn't seem designed to be removed from the closed position!
 
Have you tried the pull handle ? It’s pure mechanical,try pulling up button at same time.
I cannot recall how you do it but doors can be made to all unlock by using the button under the bonnet passenger side which activates if you roll over. It’s on the passenger side.
Somebody clever on here will be a long to tell you and will be along I am sure.
 
Hi thanks I've tried the pull handle, simultaneously pulling the button etc in all combinations. Stuck fast! Intriguing idea about the roll over button. Wasn't aware of that. Will do some research but if anyone can help locate that it would be great!

Hi. So if all the other doors are working on remote then the title of your post is wrong cos there's no problem with the central locking but with that particular door. Seems that the actuator is stuck in superlock mode then if you can't activate that motor it's no way to unlock it other than brutalise it. Put your ear on the door and listen if you hear any activity when you lock/unlock with the fob, if it's silence it's possible to be a wiring issue so check if the loom is not chafed where it passes between the body and door
 
Thanks Sierrafery. There is movement so there is current getting to the actuator. The button tries to pop up but doesn't make it. Maybe stuck in superlock mode. I have a nanocom on order due next week. Is it possible to disable superlock via that do you think? worth a try before hacking in? The drivers door is also not responding to the remote (there is no visible lock / unlock button on the drivers side) but I can use the key after disabling the alarm / immobililser with the fob. Rear doors ping open as if brand new using the fob.
 
Unfortunately it seems that the superlock motor is dead then(there are two in there) so as long as it's stuck in superlock no way to open it without "invasion". You can disable superlock with nancom but that would help you only in the future to not end up in the same situation.

PS before I close this.... the 'roll over' button. Is that a red herring? Looking around online it seems to be a fuel isolator and not an 'unlock' button. Am I right?

I think that's right. It's a cylindrical thing placed vertically on the bulkhead with a button on the top to reset it if it actions. Nowt to do with unlocking the doors as far as I know.
The only switch I know that unlocks all the doors is the one we all know about on the dash.
 
Sorry if i got this wrong.I was sure I had read somewhere about a chap with same situation as you.I may have got confused.
But with experts like SF if it was possible he would know.
I am sure you will fix it.

If you mean the inertia switch it would unlock all doors once triggered(beside cutting the fuel pump's feed) but the action has the same effect like the dash switch so as long as the dash switch is working the inertia switch will not do more
 
SF thanks. I'll have one more go with everything before destroying the door!
Westone, don't apologise you helped me get familiar with another bit in the engine bay.
Thanks for the advice.

Before you destroy the door, it may be possible to defeat the superlock, but it does rely on you being able to get the door card off with the door closed.

I recently replaced the 2 motors in my OSR locking mechanism and had a really good look at how the superlock worked, not wishing to be stuck at any time with a superlocked door!:D I was in 2 minds whether to put the superlock bits back in, but I did in the end.

If you can get the door card off, it may be possible to "dremel" a small access hole in the mechanism plastic cover and pop off the superlock lever. The inside door handle should then unlock the door.

I've got some photos I took of the mechanism and could mark these up showing the lever etc. This was for a rear offside though, but hopefully they are all similar enough.:confused: Access is not good either, but if you've got nothing to loose.....

Good luck.

PP could you send me those photos please? That would be very helpful! I don't think I can get the door panel off with it closed, but I can hopefully cause minimum damage with a strategically drilled access hole.

OK, give me a while to mark them up and I'll post them.

OK, I hope this works.

The first photo shows the lock mechanism with the plastic cover in place and the electrical connector for orientation. I think you would cut an access hole in the cover where arrowed "superlock under cover"

The next photo shows the lock with the plastic cover removed so you can see the mechanism. The superlock lever is the small light coloured piece at the end of the "arrow". You should be able to pop this off the black plastic crank with little force with a screwdriver etc.

The next photo shows the lever (and the crank) removed.

As the superlock bits are quite close to the electrical connector, you stand a chance of popping off the lever, the lock should then open using the internal handle. I've never tried this, I just hoped it was possible in case I need to do it myself.

Good luck, you will need to be a contortionist, gynecologist and have fingers like ET!!

I think I got confused, easily done...this was what I read......Its from Nanocom instructions...I am not a good Nanocom pilot.


  • Inertia: The permanent battery feed is connected from fuse 13 in the engine compartment fuse box to the inertia switch. From the inertia switch the feed is connected back to the engine compartment fuse box. From the fuse box the feed is connected to the passenger compartment fuse box where it is then connected to the IDM. From the IDM the feed is connected on the BCU. When the inertia switch is operated, the battery feed to the IDM is removed. This is sensed by the BCU, which automatically unlocks the doors, only if the ignition is in position II and the alarm is disarmed.
