Triple locking mechanism

The MTL^™800 locking system from Lockwood provides peace of mind!

To guarantee the technical key security of a mechanical locking system it is necessary to select a system that is protected by key patents and also offers a high technical key copy protection. The MTL^™800 locking system from Lockwood will achieve both of these.

Lockwood MTL^™800 provides the highest possible level of protection against illegal key duplication via the revolutionary double alpha spring. The patented platform combines protective elements to create a triple locking mechanism, superior key control, and extensive master-keying capabilities.

Double alpha spring: A unique moving element on the key blade's tip that engages with unique pins, creating an additional shearline.
Locking Bar: A unique locking bar mechanism forms a robust security layer. Correct alignment of the locking bar pins depends upon the correct combination key being inserted into the cylinder.

The milled pattern which runs along the length of the key interacts with the top bar horizontal pins, creating the required shearline.

Telescopic pin: Based on Mul-T-Lock's proven telescopic pinning technology.

What is the key difference between MTL^™800 and MT5+ ?
The primary distinction of the MTL^™ 800 lies in its use of patented active element double alpha springs in the key-way and double alpha pins in the cylinder system.
Are MTL^™800 keys backwards compatible with MT5+ systems?
All MTL^™800 keys are fully backward compatible with existing MT5+, and MT5 systems.
Are there any shared components between the MTL^™ 800 and MT5+?
Yes, both systems use the same pinning requirements, except for alpha pins in the last chambers. Additionally, the profiles are identical in both MT5+ and MTL800.
What are the different components in the MTL^™ 800 and MT5+?
The MTL^™ 800 introduces inner and outer alpha pins, whereas the MT5+ continues to use a single alpha pin. Each system has unique barrels. Additionally, the MTL^™ 800 features a patented key with double alpha springs, while MT5+ keys are no longer available for purchase.
