Disabling The Automatic Door Lock

[Lum]

My A31 (1993 SE-4) has always done this thing where once the car starts moving it fires the central locking and locks all the doors, except the drivers. It's always annoyed me a little bit but not enough to do anything about it.

Unfortunately this system seems to have developed a fault, if you attempt to unlock one of the doors it instantly locks it again. It appears that the door lock actuator is being fired continually which I imagine is going to wear them out sooner or later.

I'd like the keep the central locking working, but disable this one specific feature, is there any way to do that?

sounds similar to what the new Hyundai's do where all the doors lock after 15km/h it's part of the safety and i believe it can be disabled at the service department.. not sure if that's of any help but i'd take it to someone that knows their way around a locking system.

Chris Rogers for instance.

It's a factory feature, it's not a fault & it's not constantly firing, the master unit for the central locking detects when the locks actuate and will try to lock them again.

They won't 'wear down' over time because of this.

If anything, trying to manually unlock the door while moving will wear our parts, hitting the button on the driver's door probably doesn't do much good either.

I know of one dude that ended up with a bent door lock actuator rod from a passenger trying to constantly override it.

Central locking is controlled by the passenger side power window switch (it's built in)

Other than removing your speedo, or removing your central locking and/or passenger's power window switch, I don't know of any way to remove it.

You could get someone else to drive, , unplug the passenger window switch and use a multimeter to look for a signal that comes on around 10kmp/h (often 15 or 20kmp/h with older/stretched speedo cables), theoretically there's a wire off the dash that triggers something inside that switch to lock all the doors.

Don't know if it's a simple as cutting one or two wires and if that'll cause other issues, but if you're that desperate to get rid of it, it's worth a shot.

Had a look but apparently my search abilities suck, not helped by the fact that all the results for "lock" are about steering, probably also not helped by my lack of knowing Australian English.

The reason this came about is my GF managed to get her hair trapped in the door and didn't notice until I was joining the motorway, when she unlocked the door the dam thing fought back hard enough that it bent her fingers back.

The car will only lock the passenger doors, not the drivers side....so, the safest place for your girlfriends hair is probably in your lap....just saying....

Why was her hair near the lock anyway? that's a mile away from the headrest.....

Windy day and her hair is waist length so easy to trap it when closing the door, hell I manage to shut my own hair in the door sometimes and mine's only armpit length. I usually notice before reaching a sufficient speed for the doors to auto lock.

As for your other suggestion, while it has appeal it would be somewhat easier if I were a bloke
