press the key twice to activate the alarm

dear friend-when you use the remote it activates the alarm,and when u use the key it only activate the central locking,please open the bonnet and look for the bonnet switch,if you find the switch look where the bonnet and switch come together there should should be a rubber grommet that will push the switch when closing the bonnet.if it is not there the alarm will not work,do the same with the back door.

check the alarm and central locking computer on your right of the steering wheel , unlock it and reset it after 1 hour you can try again and it should be reset and the alarm will sound if its active.

If im not mistaken,your car should have an alarm reset/override.Below the steering column,on the dash should be a slot where you put your remote transmitter to deactivate the alarm.If that works,you then need to have your remote checked and coded by a vw dealer.Good luck.

It means that the remote is not passing the signal to the car . The alarm has triggered because the system has detected an illegal entry. Replace the remote batteries
