Master Lock 5UP 2 in universal pin laminated safe

Universal Pin Padlock

This laminated steel padlock uses Master Lock’s universal pin system so it can be keyed to an existing Master Lock key in minutes. The 4-pin tumbler cylinder and dual steel levers secure both sides of the hardened boron alloy shackle. It is sold without a key and requires the universal punch tool for key matching. The 2-inch wide body provides a 1-inch vertical and 15/16-inch horizontal shackle clearance.

Installers matching existing Master Lock keys

Suited for locksmiths or facility managers who need multiple padlocks operated by a single Master Lock original or M1 blank key. Buyers who do not already own the universal punch tool or compatible key blanks cannot use the keying feature. Anyone needing a padlock that works with a different brand’s key or a keyless combination mechanism should look elsewhere.

4-pin tumbler with universal pin keying

The lock cylinder accepts Master Lock’s universal pin technology, allowing pins to be sheared to match a customer’s existing key. This specific mechanism only functions with Master Lock original or M1 key blanks and the dedicated punch tool. Without those components the padlock cannot be keyed to the desired key code.
