These two bypass shanks are made to reach that shaft on suitable locks, with two serrated-grip sizes for different shafts. Use the right bypass only where the mechanism allows it. Why these work The target is the drive shaft, not the button code Two sizes Two serrated-grip shanks for different drive-shaft sizes. Push-button focus Made for suitable mechanical push-button code locks where the shaft can be reached. Bypass learning Useful for understanding how some mechanical code locks should be protected. Build the bypass kit Different doors need different approaches For latch bypass work, compare the Shove-It Lock Bypass Tool. For door-gap and spacing work, see the Wedge and Crowbar Set. Details What to know before buying Tool type 2-piece bypass lock shank set Use case Suitable push-button mechanical code locks with reachable drive shafts Sizes Two serrated-grip sizes SKU SHAN Fit note Not every push-button lock exposes the right mechanism for this bypass. FAQ Questions buyers usually ask Does this decode the combination? No. It bypasses suitable mechanisms by reaching the drive shaft. Will it work on every code lock? No. The lock design must allow access to the shaft this tool engages. Why are there two sizes? The two serrated-grip sizes help with different drive-shaft sizes. Is this a picking tool? No. It is a bypass tool for a specific mechanical weakness. Know the mechanism before you reach for the tool For the right push-button code locks, these shanks are a clean way to study and demonstrate the bypass.
