Default Keyless problem

Keyless does not work. The open/close button on Remote does not work. It still does not work even replaced the battery. Only the physical key can open/close the door. Anyone comes across on that ?

Does the remote led flash when remote buttons are pressed? It should. Also, when using the keyless system, when you touch a door handle to open/lock the doors or use the start button, the led should also flash. This would mean the remote is receiving a signal from the car and sending the authorization signal.

Mine stopped working for a few days after I used the vag cable on it to tweak a few things. Started working again soon after though.

Default Keyless problem

Thanks for the tips ! The LED does flash when I press the button on the remote. But it still can't open/lock the door. It seems to me the Central Lock System has some problem (might not the keyless sensor on the door handle) ?
