Blockstory Safe Lock Replacement Cylinder

The Blockstory Safe Lock Replacement Cylinder is a drop-in key lock cylinder for residential and small business safes that use a standard 22mm diameter external cylinder format. Safe lock cylinders wear over time and can be compromised if keys are lost — replacing the cylinder with a new Blockstory unit restores full security and eliminates the risk of unauthorized access with a copied original key. The 7-pin tumbler configuration provides significantly higher picking resistance than the 5-pin cylinders typically installed in budget safes. The anti-drill protection plate — a hardened steel disc behind the cylinder face — resists drilling attacks that attempt to reach the locking cam mechanism. Blockstory machines the cylinder to standard 22mm × 55mm dimensions and includes the cam adapter set for both left-hand and right-hand safe installations. Supplied with 3 keys. Compatible with most Blockstory safe models and common third-party residential safes using standard cylinder formats. Dimensions: 22mm diameter, 55mm length. Weight: 95g.
