Right Term For Locking

[Prudie]

What is the correct name to use (if I wanted to do an online search for problems for example) for the system that makes a car automatically lock the doors as you drive off?

[-Talbot-]

car auto lock system

[bednobs]

power door locks

[-Talbot-]

Can't seem to find anything to help though.
What's the problem?

[Prudie]

Oh is it just auto lock :-(
power door looks like that's when the driver pushes a button to make all the doors lock but I mean the automatic system.
Problem is as soon as I turn hard right or go over a bump they unlock and don't go down again. It's minor but something must be wrong.

My Volvo calls it "Automatic locking" - when the car reaches about 5mph all the doors lock.

Central Locking System?

[gingejbee]

VAG call it "automatic speed-dependent locking and unlocking system"...operates at 15km/hr (9mph)

[Prudie]

Yes it does seem to be auto lock (or automatic locking). Not the same as central locking. Thanks for all input, I can search now

Can be abled or disabled ( look in car handbook ), most probably a dodgy connector or printed circuit board in the central locking module.
You can get them second hand fairly cheap.
