Master Lock

Keeping Our World Under Lock and KeyMaster Lock products for security solutions from Aro Lock & Door 

Founded in 1921 by Harry Soref, Master Lock is proudly Milwaukee-made, and is still North America’s #1 padlock manufacturer. Their product proves strong enough for an impressive television commercial featuring a foiled Magnum .44 pistol bullet fired at the padlock, failing to break the lock.

Master Lock provides top-quality products for both commercial and residential buildings, protecting what matters most. Our experienced Milwaukee locksmith specialists can determine the type of locks and security your home or business needs.
