Here is a quick look at what is better known as “Spilt Wafers” car door lock .
This is a Honda HON 66 lock which contains Seven spilt wafers and one full wafer in the door lock.
The lock is divided into Axis A & Axis B , on the door lock there are 3 A wafers And 4 B wafers and another full wafers (B5)
The 3 wafers are named A 2, A 3 &A4 the full wafers is B5
The other side is B1-B4
There is total of 6 heights and 12 cuts when cutting the key if I’m not mistaken.
Picking the lock is very awkward as you must pick it twice to open the door and then pick it twice to return to the orignal position. I did see one lock that was caught in the 45 degree position because of what seems to be a worn key (the owner swore it wasn’t picked or played with).
Cutting the HON 66 key is not easy even on the Quattrocode as the key must be measured before.
