AccuReader for GM-Z Keyway – Non-Ortec

AccuReader for the GM 10 cut Z keyway (B106) WARDED and UNWARDED locks. Designed to read each space in any of the GM 10 cut Z locks (excluding ignitions). Comes with directions and a handy storage container.

This system will allow you to read the new GM locks commonly called “Z-key.” Following a few simple steps it takes only minutes to read the depths for each cut in each position of a given lock. (ignitions excluded)

The AccuReader works on the process of elimination to decipher the correct depths of the lock. By checking the deepest cut first you eliminate what the cuts are not. Therefore it is essential to always read depth slide #5 first.
