Hi all. Hoping someone can help. I had the unfortunate pleasure of having my rear screen smashed in a smash and grab having parked in central london. Drove home with a smash rear screen. Now i wanna lock the car but the alarm keeps going off. I suspect its because of the interior sensors - ie no rear window. I have deactivated keyless go by tapping twice but this just locks it. How do I go back to full manual mode? Ie no keyless at all? Thanks in advance
