It's just a bike

You can increase the range of the remotes by holding it against your head...apparantly it has something to do with the signal being magnified by the lenses in your eyes. Try using your central locking while walking away from the car, when you are out of range put the remote against your head and press the button....it works 9 times out of 10.(saw it demonstrated on Top Gear and had to try it for myself)

Sounds a bit like the mobile phone trick but i will giv it a try
