I found it took 4 presses of the fob today to unlock my Jazz.
Thinking that the battery was in need of changing, I tried prising the fob apart.
It didn't really want to co-operate but I persisted to the point where only that part of the fob in contact with the blade of the key would not separate, and then "mechanical sympathy" made me feel I should pause there
The two halves of the fob appear to have been glued together.
Before I apply more strength to force the fob fully apart, I'd like to ask whether anyone else has been in this position?
