Door Handles Keep Disconnecting/Not Working

Recommended Posts

My 2007 LCI E60 front passenger and driver side door handles (both inside and outside) keep failing.
The car doesn't has comfort access and usually works like normal with the key to lock/unlock the car and all doors, and I have to put the key inside the ignition and hold the clutch in whilst pressing the start button to start the car.

My door handles have always worked perfectly since I owned the car.

A couple of weeks ago, a friend who owns a vehicle wrapping business and I vinyl wrapped my car which involved removing the door handles. We followed instructions to remove the handles and then reinstall them, and they worked fine for a couple of days until one night I got home and went to go and get out of my driver door and it wouldn't open from the inside.
I rolled down the window and it would not open from the outside either.
I then tried locking and unlocking the central locking using the dashboard centre button and also the key but it made no difference - the door was locked shut and won't open. For a couple of days I had to climb over the centre console into the passenger seat and open the passenger door to get out and back into my car (very annoying).

Then a couple of days later the passenger side door handle also failed in exactly the same way as the driver door. Wouldn't open from the inside or outside.

The locked front doors will then not open until we go through the process of removing the rear doors to be able to access the the lock mechanism on the front doors where i have to remove the front door handles and assemble them all again properly before putting it all back together. The handles then worked perfectly again from both the inside and outside.

A few days later and the exact same thing happened again, first the driver door and then the passenger door.

This has now happened twice (where both doors have randomly stopped opening after a couple of days) and I suspect it may be some sort of electrical/safety measure/deadlock issue.

I think it must have something to do with the unlock/lock mechanism itself and not the handles because they "feel" as though they are still connected and the 'pin/knob' at the top of the door card that raises/sinks to indicate if the door is locked will raise up as normal when the interior handle is pulled if the door is locked. For example if i sit in the driver seat with the key in the ignition and press the centre dash lock/unlock button to lock the doors, and then pull the interior driver door handle, the pin will rise up at the top of the door card as normal, but then a second pull of the handle does nothing (where it would normally open the door).

Please can anyone help me??? What is happening? How can the doors open fine for a couple of days and then randomly not work? But then if I take the doors apart and reassemble everything in the same way I did each time, it all works fine again??? I am extremely puzzled.

I appreciate any help at all!

The front doors won't open at all using the inside handle or the outside handles. If i press the unlock button on the key or the unlock button on the dash inside the car it makes no difference, the pins pop up at the top of the door cards as if the doors are unlocked but won't open when i pull the handle. However if I press the lock/unlock button again, the doors will lock and all the door card pins will go down, and if I then pull the inside door handle of my driver/passenger front door, the pin will come up as normal (suggesting everything is connected normally inside) but then a second pull of the handle does nothing, where it would normally open the door.

Are we talking about comfort access or regular remote locking?

Sounds like the locks are sticking in a deadlocked burglar proof state, likely caused by the dissassmbling process. Only stating the obvious, as sadly I'm not that familiar with the mechanism.

 

Edit: From the outside of that car, can you turn the physical key onward a little more to dis-engage the dead locks?

Turning the key in the lock seems to work as normal as far as unlocking and locking the doors (the pin goes up and down on all doors) but it makes no difference to the doors opening. Anyone got any ideas??

I had a similar problem with the front N/S door, it wouldn't open from inside and outside. I thumped the area around the 'arbag' tag with side of my fist, which seems to have done the trick. It happened twice and haven't had any issues so far.

 

I tried to 'correct' the outer handle on the rear N/S door. However, I accidentally pushed the lock further and door handle clip/hook would not slot in to the lock. I had to remove the door card and membrane. There is a hole below area of bowden cable where you can disengage the lock using a long screwdriver which will avoid removing the membrane.

 

Refitting the handle was tricky, however I realised that I had to push on to the lock from the inside with the screwdriver whilst tightening T20 screw from the side.
