Front Side Door Lock Cylinder Coding
The door lock cylinder only uses 7 of the 10 cut positions, 3 through 9. The tumbler positions are staggered from side to side, 4 on one side and 3 on the other side, are self-retaining. The left and right door lock cylinders are identical. The lever assembly determines which side of the vehicle the lock cylinder is for. After removing the current lock, record which lever is used and the orientation of rod clip.
Note: All lock cylinders for side milled keys have right and left tumblers. The location of the tooth of the tumbler determines whether it is right of left. Illustrations in this procedure show the right tumblers on the top and the left tumblers on the bottom. All tumblers are marked 1R, 1L, 2R, or 2L. The number being cut depth and the letter meaning right or left.
