MT5 Mul T Lock Oval Dual K&K Cylinders

The Mul-T-Lock MT5 UK Oval Dual Key & Key (K&K) Cylinder provides high-security protection for doors fitted with UK oval profile lock cases. Operated by a key from both sides, this double cylinder is ideal for residential and commercial applications where controlled access is required from both the interior and exterior.

Built on Mul-T-Lock's advanced MT5 patented mechanical platform, the cylinder features a dual-locking mechanism. It combines a high-precision telescopic pin configuration with the innovative Alpha Spring at the tip of the key. The Alpha Spring engages a unique pin at the rear of the chamber to create an additional shear line, offering exceptional resistance against picking, bumping, and drilling.

For superior key control, the MT5 system uses a coded magnetic duplication card. Additional keys can only be cut by authorised locksmiths upon presentation of this card, preventing unauthorised duplication.

These cylinders are available in a 70mm (35/35) size in both brass and nickel finishes. Please select your preferred finish from the options below.
