The new concept - three mechanisms for more security

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 new MT5 locking system from Lockwood will achieve both of these.

Lockwood MT5 provides the highest possible level of protection against illegal key duplication via the revolutionary Alpha spring. In addition every Lockwood MT5 key will be covered by patent protection well into the future.

There are two levels of security, the base level is the MT5 cylinder that uses a telescopic pin and alpha spring for restricted security. MT5+ builds on this by adding a locking bar for optimum security and high level master keying capabilities.

1. Alpha spring

At the tip of the key is a revolutionary mobile interacting spring - the alpha spring. The alpha spring engages a unique pin at the rear of the cylinder mechanism creating another shearline.

2. Telescopic pin

This new-generation product is also based on a new configuration telescopic pin technology.

3. Locking bar

The locking bar mechanism is the third technology featured in the MT5+ cylinder. 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.

With Lockwood MT5 originals are hard to copy

All MT5 products have a double-sided unique MT5 key. One set of cuts are for the telescopic pin mechanism and the other cut, the milled pattern, is for the locking bar in MT5+ products. The MT5+ combination provides enhanced key security and a higher manipulation resistance.
