Cheers lads, got the new fob thru from eBay this morning, just swapped the innards over and it's working a treat (and more importantly, hanging from my keys). You were both right, it was a very simple job. The only thing is, you still seem to need to be quite near the car for it to operate. Not as near as before, with the old batteries, but still within 5 or 10 metres or so. That's not right, is it? I'm not too bothered about it, but it would be nice if it worked from a bit further away. Batteries? Or is it just a shit system?
I even tried the 'hold it against your head' thing, but still no joy.
Excellent news Gordon
I think range is down to the fact its a bit of crap system
I remember mine being the same to be honest.
There 'may' be a way of improving the range and I will see if I can find any info on it!
