Master Lock
Master Lock has been making padlocks and security hardware since 1921. Nearly every keyed lock it sells carries a code, and a replacement key can be cut from that code alone. Everything we stock for those locks is here.
The code is stamped on the lock itself, usually on the back of a padlock body or the face of a cabinet lock. Padlock keys cover the laminated, brass and disc padlock lines. Office furniture keys cover desks, files and cubicle storage. Key blanks suit locksmiths cutting their own. Everything else is cut from our general Master Lock keys.
Can't find what you need? Contact us by phone, email or live chat. Our US-based customer service team is here to help.
