ABSTRACT:
The objective of the invention is to allow the user to decipher the cuts (aka. depths) on a key from the lock without disassembling the lock. The current wafer lock readers on the market rely on a sensitive touch to operate and/or do not give the exact depths to recreate a key. Our wafer lock “reader” will give the exact depth of a cut, coming to a definite stop at the reading position for each cut on the key.
