My remote locking key for my 147 is flashing red when I press the buttons. The manual says that this means I need a new battery. However, I have changed the battery and it is still doing the same thing.
The majority of times the key will only lock or unlock the car after several attempts (or not at all) and there have been a couple of times when I have been locked out completely as I have locked the car using the key which has activated the alarm but then I cannot unlock it using the key so the alarm is still activated (if that makes sense!!).
I have resorted to locking the key manually at the door handle but this obviously does not activate the alarm.
Does anyone have any ideas what could be wrong?
