Restore security instantly and economically!
Interchangeable core padlocks and door locks don't require disassembly in order to change the cylinder. The figure-8 interchangeable core can be removed and replaced with a single control key.
This convenience addresses common security issues:
- Preventing access when a key has been lost or stolen
- Resetting individual doors or gates with different locks to selectively limit access to authorized personnel
- Re-securing a building after temporary or contract employees end their term
- Securing a building against terminated employees
The Master Lock assortment of cylinders includes 16 distinct keyways to match existing profiles from Best®, Falcon®, and others. Cylinders, ProSeries® padlocks - Solid Steel, Solid Brass, Solid Aluminum, Weather Tough® and High Security Shrouded locks, with cylinders and mortise or rim cylinders for door applications are all available.
