Is it the rain????

[SteveY]

Apropos of my previous post about key fobs .... the process listed before to reprogramme my key fobs worked fine, however, two weeks later and they didn't work again. Reprogramming didn't work so I connected up the trickle charger to see what the battery had in it, after 20 minutes it was at full charge and the key fobs still didn't work, so had to think again, disconnected the trickle charger and went back in the house. Next day they worked again with no intervention from me. Hadn't rained though .... Worked fine for some time and then after a heavy rainstorm ceased working again, though the car is under cover when parked. This has happened a couple of times since, not the battery as a 110 mile blast to the New Forest and back over the weekend means I have a fully charged battery, though it rained when parked down in the Forest the key fob has worked consistently.

My question is .... the unit in the boot is dry, so where should I look now if -- as I believe -- the rain has something to do with it? Where is the aerial located that the unit/fob interact with?

The car is a 2004 XK8 convertible which apart from this gives me minimal trouble for the fantastic experience of driving it?

Help would be appreciated.
