DIY: Identify your early Datsun keys
1st: Definitions!
Now Start!


FRONT SIDE or FACE of the key: this is the face where the cuts bite into a groove. It may or may not be the face with the logo, that can be on either face.

REAR SIDE or FACE of the key: will also have a groove, but one that is intact, not bitten into by the cutting.

SINGLE-SIDED key has cuts on one edge only and the front and back sides or faces are not identical.

DOUBLE-SIDED key has cuts on both edges and both sides or faces are identical.

SHOULDER or STOP is the part that sticks out after the cuts and determines how far the key will enter the lock. When there are two shoulders at different positions we are interested only in the one nearest the tip.


Is the key single-sided?
(see definitions).

YES -- continue.

NO -- email for further instructions.

 

Measure the distance from the tip to the first shoulder.

If it is 21 mm (= 13/16 inch) -- go to A.

If it is 17 mm (= 11/16 inch) -- go to B.

If it is 25 mm (= 1 inch) -- go to C.

If it is 27 mm (= 1-1/16 inch) -- go to D.

Look near the head. On each side one groove will be consumed by the cutting but the beginning is there.
