Been having a bit of trouble with the remote central locking on the
medway handyvan this week.

I suspect I need a new battery in the key because the range that it
works at is steadily getting smaller.

So, I've been using the 'hold the remote to your head' ploy - which
to my surprise actually works - it easily doubles the range of the
remote.
How the hell does that work? It certainly isn't the power of my
brain.........
