Mul T Lock MTL500 / MT5 Euro Double Cylinders

The Mul-T-Lock MTL500 (formerly MT5) Euro Double Cylinder is a premium high-security lock designed to provide outstanding protection for both residential and commercial properties. This advanced mechanical platform integrates Mul-T-Lock’s field-proven technology to offer next-level security and key copy control.

At the heart of the MTL500 / MT5 cylinder is a double locking mechanism. It combines a high-precision telescopic pin tumbler system with the patented Alpha Spring - a unique mobile element located at the tip of the key that engages a special pin at the rear of the cylinder. This multi-layered design provides exceptional resistance against picking, drilling, and bumping.

To prevent unauthorised key duplication, each cylinder is supplied with a unique coded magnetic card. Additional keys can only be cut by authorised Mul-T-Lock dealers upon presentation of this card.

These double cylinders are available in a variety of overall sizes, ranging from 31x31 up to 45x55, and in either a classic Brass or modern Satin finish. Please select your required size and finish from the options below.
