Both keys for my car have had the rubber pushed through/split so I've ordered new buttons.
However, the spare key had the boot opening switch broken away from the PCB.
I've just replaced both switches on the spare key, using switches off ebay @ £1.70 for 3 of http://www.ebay.co.uk/itm/390368257141. I might have been lucky that the pads on the PCB weren't too badly damaged so changing it was a doddle.
I then synced it to the car using the method that I read about on here, cycling the lock using the working key until it no longer responds, then press the lock buttons on each key fob
= two working switches
Just thought I'd share if anyone else has the same issue and is worried about giving it ago.
