Difficult to lock and unlock.

Once unlocked system will lock itself again .

Will also lock and unlock itself repeatedly .

Occasioanaly will lock OK but then open both front widows and leave the car unsafe.

Using Key rather than button press makes no difference.

Car in motion problem can still occur.

I also have a problem with my central locking. The locks are stiff to operate with the key (the only option on my model) and both front windows sometimes open by themselves.
