What are Ultion Locks?

Ultion locks are high-security euro cylinder door locks engineered to protect against the most common break-in methods, including snapping, drilling, bumping, and picking. Manufactured by Ultion (founded by Steve Stewart), these locks use a molybdenum core, Lockdown Mode™, and unique key control to offer advanced security not found in standard cylinders.

Ultion locks are trusted across the UK and meet the highest security accreditations: TS007 3-Star, Sold Secure Diamond, and Police Preferred Specification (Secured by Design).
