Spotted this on Pistonheads, and thought it would be worth posting here:
"Found a bundle of keys including a Porsche key on the A4 near Maidenhead.
Going to hand them in at the Maidenhead police station later today, so if you've lost the keys to your pride and joy hopefully you'll be able to pick them up from there."
