My sigma alarm has stopped locking the doors but otherwise seems ok ... Is this a common problem or has the central locking module gone US ? IS ther a way to re boot the alarm ?

It will be the motor in the door most probably. It is fitted in the UK to activate the cars OE central locking.

Hope this helps

My GT alarm did this, turns out the locking relay box had filled with water Had to get a new box, £20. I can't say it's the same on yours but it sounds highly likely, have you checked the fuses?

Fuses ok ( under the bonnet anyway unless you know of any others). Is the motor in the drivers door do you know ? The central locking is fine when using the key. It`s just the ultrasonic wont activate it or the self close windows although It beeps and alarms the car?

The motor that Dave mentions will be in the driver door, it fastens to the rod on the door lock, it basically has the same effect as you turning the key.

If the windows aren't closing either I'd say it's deffo a problem with the control unit, I'd take it to a dealer.
