This is a Medeco 11JR500 Maxum M3 BiLevel Residential Deadbolt Lock with 5 Pins, a Single Cylinder, and Bright Brass finish.
With patented key control you will have complete control over who has keys to your locks. No more wondering if someone you gave or lent a key to, ran to the nearest hardware or big box home improvement store and made duplicate keys to your locks. Only you are authorized to request additional keys. A unique authorization card is issued with each key combination and is required to order additional keys in the future. Medeco accomplishes this by owning the patent on their technology, therefore no other key blank manufacturer is permitted by law to reproduce their key blanks. Medeco strictly enforces their key duplication policies through their dealers.Features
