Got out of my car 2 days ago, locked it, went into a shop, came out and fob wouldn't work. Then I find the normal problem that driver's door lock won't turn with the key. Had to unlock the boot lock with the key, climb through the boot and manually override the alarm.
Drove the car home and the fob started working again. My other key hasn't worked in the year that I've had the car.
Took it to Audi and they replaced the batteries in both fobs and resynced them. Now the key that did work doesn't work and my other key now does work. The Audi parts key siad the keypads are knackered on the fobs and it may work if I replace them at £60!
Anyone got any other thoughts on this - should I try and source new style keys from internet instead?
