Those silly little things ...

Most cars today have some form of radio frequency based remote keyless system for locking / unlocking a car.

Many of these use small internal batteries within the fob, which need to be replaced when they run down.

Why?

The key is connected to the ignition when driving, the car has a walloping electricity generator and a battery to boot. Can't these key batteries be recharged whilst driving?

grumble, grumble...
