So my next car looks like being one with keyless entry / ignition.
My solution to the current electronic key is to have an old style mechanical key on a string, lock the electronic key in the car, and then use the mechanical key to get back into the car. Works well.
But the newer keyless entry / proximity gizmo's means the car won't lock with the key inside the car, and some new cars don't have an external keyhole anyway.
Taking the electronic gizmo surfing doesn't seem like a good idea.

Anyone with a (sensible) solution?
