Some locks have 5 pins, others have 6, Ultion has 11

Which means it has... 294970 different key combinations. The Ultion cylinder is one of the most secure on the market - so much so in fact that no test has beaten it. The cylinder has passed all major British standards test for security without the need for cylinder protectors or extra secure door handles. These tests include the highest TS007 standard (3 stars) and the extended Sold Secure Diamond test, which is more rigorous and designed by the Master Locksmith Association. No test has beaten the Ultion lock.

Yale TS007 3 handle/cylinder combination

Yale’s Superior cylinder and Platinum handle combination is accredited with the coveted TS007 3* BSi Kitemark - the most secure available for composite doors and locks, introduced by the Door and Hardware Federation with the GGF as an answer to vulnerable cylinders. The cylinder has been subjected to extensive tests and is one of the most secure cylinders on the market. It's anti-bump, drill, pick, tamper, torque and force resistant.

ERA Vectis cylinder-free lock

The ERA cylinder free lock is our latest high security option. With a traditional mortice key the door doesn’t need a euro cylinder because the key engages directly with the multi-point lock. No cylinder means no risk of the door being opened by a burglar snapping, bumping or manipulating the cylinder. The lock edge of the door is then completely wrapped in a 3mm powder coated aluminum strip, top to bottom and front to back creating a seamless single finish.
