The SPARROWS Bump Key Expansion Set covers the next four most common, higher security commercial and residential key ways. Also included is one padlock bump key. You are better off buying this as an expansion to our other set unless you have a special need for one or more of the keys in this set.

All SPARROWS Bump Keys are made with original cuts to the deepest settings to ensure a factory quality reproduction. With proper technique, a bump key will be able to open a high percentage of locks quickly and efficiently.

• 1 x Arrow (AR1)
• 1 x Yale (Y4)
• 1 x Master (M10)
