Hello, I'm Anthony and I have a 2003 T4. After 17 years and 188.000 miles of enjoyable and mainly trouble-free driving, I now find I can't unlock the car either electronically or with the physical key. It was locked normally with the key fob, but now does not respond in any way to either of the two keys I have. I don't think it can be the battery in either of the keys because the little red light in the fob comes on when I press the open button, but the car lights do not flash in response to either the lock or the unlock button. I therefore conclude that the 12v battery must have failed. But for some reason the physical key won't open the driver's door lock; it turns freely clockwise, which I believe is to lock, but only goes a little way anti-clockwise which I belive is unlock. So I'm completely stuck, there seems no way into the car at all!. Does anyone know of a clever way I can get in at least to release the bonnet lock? Grateful for any suggestions.
