Replying to Topic 'What kind of keys?'
Never saw a Lexus key up close so I am not sure...
The concept of the VW key is that it is thicker than a normal key. Normally, keys have straight grooves on their "sides" and teeth on their "edges" (sorry, I can't find better terms).
The VW key has a smooth flat edges. In addition, it has only one large groove on either side. That groove however, is not straight. It moves up and down along the key. So instead of using the edge of the key, the tumblers in the lock use the grooves on either side of the key.
Technically, I don't know whether this is better than any other system. However, it does look cool.
