Hi all
The open button on my key has stopped working

The lock button still works fine but I just can't unlock the car remotely

... I wasn't thinking straight when I noticed first thing this morning; still half asleep I unlocked the car with the key, put my bag on the passenger seat, sat down then nearly put my head through the sunroof when the alarm went off!!

I had to check my pants after that one, phew!
Unfortunately, I bought my car privately and didn't get a spare key. I will speak to the Stealers in the morning and prepare myself for the worst. I've heard of people paying silly money for key faults. Has anybody had this fault before whilst out of warranty?
