Meridian Security Systems provides high quality lock and keys for business offices and domestic residences. There are several reasons to select Meridian keys and locks, including the company's standard one year warranty. Meridian also offers ASSA products and makes its own ASSA master keys at its Horsforth shop.

ASSA High Security

ASSA is a lock-making company that produces durable and heavyweight locks for a variety of applications. Prisons, military sites, and security businesses all trust the ASSA brand name to provide exceptional locks. Meridian carries a wide selection of ASSA locks in the UK.

ASSA DP Cylinder Lock

ASSA uses a patented dp cylinder lock system. Cylinder locks consist of a pin and tumbler lock core. There is a set of six puzzling pins cut at different lengths inside the main lock chamber. Only the correct key fits into the lock and uses its blades to push the pins upwards. The pins then turn the cylinder, which in turn activates the cam and releases the deadbolt. Turning the lock the other way pushes the deadbolt and locks the door.

High Security Locks

Meridian offers three different security levels of ASSA dp cylinder locks. The High Security version uses a 2400 dp cylinder. This model features a patented locking mechanism and keys along with a false gate that prevents picking. There are billions of differs for the High Security lock. Every Meridian key combination is unique, and no other lock contains the same key pattern anywhere in the world.

Extreme High Security Lock

The Extreme High Security lock uses a 4400 dp cylinder for increased security protection. This model takes extra steps to protect against picking by including both a false gate and drill-resistant inserts. It too uses billions of differs, and each key consists of a unique combination. The extra-thick nickel silver keys fit perfectly with the heavy duty 4400 cylinder lock.

Maximum Security Lock

The Maximum Security Lock uses a high-tech CLIQ dp cylinder that combines mechanics with electronics. CLIQ uses a patented system that includes an electronic sensor inside the lock. Each CLIQ key has a encrypted electronic code, and if they two do not match, the lock does not work. Even if the key fits inside the lock, the electronic sensor prevents it from activating the lock. CLIQ is effective against picking and one of the safest locking systems on the planet.

CLIQ Keys

The CLIQ key might look just like any other ordinary key, but it’s a bundle of high security technology packed into a very small design. Each key contains an individual ID code for its particular CLIQ lock. Each one uses a miniscule Lithium battery that lasts for 2 years. The battery powers the electronic signal as well as an internal quartz clock and LED light. The electronic signal contains an encryption code that makes it impossible to copy the key. Meridian offers both standard and master versions of the CLIQ key. Since these keys cannot be copied on the user's end, for security reasons owners need to purchase several copies from Meridian in case one copy goes missing.

Meridian combines traditional lock design with innovative technology to offer market-leading products. These heavy duty locks carry a worldwide reputation that does not compromise on safety and security. Pick from three different protection levels, or create a custom system that uses different levels on separate areas of the office for an effective yet affordable anti-theft system.
