Medeco locks are amoung the most secure high security locks in the world. Installing a Medeco3 cylinder on your home will provide unsurpassed security for your family and valuables.

Medeco locks started as a small tool and die company named Mechanical Development Company. Mechanical Development Company was out of Salem Virginia and was started in 1968.

The employees of the company developed and patented keys with angled cuts and rotating pins which provided a security level above anything available at that time.

Medeco3
For residential security the only lock system I would suggest is the Medeco3 system. With Medeco3 you have 4 primary benefits you don't have with standard locks, keys and cylinders.



1. Pick Resistance - Medeco3 cylinders are near impossible to pick even for the best locksmiths in America.

2. Bump Resistance - The design of Medeco3 pins, keys and cylinders make them very bump resistant.

3. Drill Resistance - Medeco designed Medeco3 cylinders with special anti-drill material strategically located in vital areas of the cylinder. This makes drilling a Medeco3 cylinder a very difficult task and will likely prove impossible to the average burglar.

4. Key Control - With Medeco3 systems you receive a key that has a patent until 2021. This means only specified locksmiths are able to get the keys. In order to get a key copied you need identification so only you can get a new key. If you lend out a key, you don't have to worry about copies being made before the key is returned.

Medeco3 cylinders have been tested by the UL and have received a UL437 Listing. They also carry a ANSI/BHMA A156.30 Level A certification and are classified as high security.

Medeco3 cylinders can be installed in many different types of locks. In residential situation you may need to purchase new lock and door hardware that will allow the use of Medeco cylinders. Medeco cylinders can be retrofitted into some residential lock. Medeco also makes a variety of residential locks of which more information can be found below.

Medeco lock cylinders
Medeco has implemented Medeco3 into several types of cylinders that include key in knob (KIK) cylinders, mortise cylinders, rim cylinders, cam locks, switches and more. Medeco has done a good job providing you with versatility for your locking needs.

You can purchase a standard commercial knob or lever from a local locksmith or online and install a Medeco3 KIK cylinder into it on nearly all residential doors. The same thing can be done for deadbolts with the purchase of an Arrow or Lori Deadbolt. If you have a front door handle set it may accept a mortise cylinder which can be Medeco3.

If you cannot figure out what will work, call a locksmith out to take a look. It may even be possible to find one that will give you a free quote.
