Help please with AUII Central Locking

[Chippar]

: I cannot lock the doors on my AUII Sedan with the remote.

The doors lock then immediately unlock and this happens every time. I now see that the "open door" light on the dash is lit up and won't go out no matter how many times I shut the doors to make sure that they're closed properly. I have also tried a new battery in the remote but it does exactly the same thing. The remote activates the boot and panic alarm properly.

I have read a few old threads on this subject, where suggestions are abundant, but none have actually shown what has been done to fix the problem.

Any assistance, except from Fraud, will be greatly appreciated.
