The ultimate in home security is here. The Ultion 3 Star PLUS is our strongest lock ever — easy to install, packed with the latest in anti-break in technology, and comes complete with a £5,000 guarantee.
What makes an Ultion lock so incredibly tough is the molybdenum core that forms its independent central cylinder shield. 25% denser than iron, this metal is not only extremely ductile and resistant to corrosion, but has one of the highest melting points of all pure elements.
We tested the Ultion 3 star PLUS for over 1,000,000 cycles — not just the 100,000 needed to pass the TS007 durability cycle test.
Inside every Ultion 3 and 3 PLUS door lock is an additional hidden lock, another layer of protection against intruders. Encased inside a solid molybdenum core and secured with a dedicated retaining pin, the lock is triggered when signs of forced entry are detected – activating LockDown Mode™. Once activated, your home and family are safe.
We’ve gone above and beyond to load the Ultion 3 Star PLUS with as many security features as possible, because nobody should feel unsafe in their own home.
Anti-pick. Anti-bump. Anti-drill. Ultion 3 Star PLUS gives complete protection against break-ins attempts.
We’re so confident in our locks that we’ll put our money where our mouth is — £5000 to be exact.
Every Ultion lock comes with free KeyControl to stop unauthorised key copying.
Precision-cut keys that are 60% thicker than the rest of the market, meaning more resistance to snapping & bending.
New and replacement Ultion locks are easy to use and install.
Police preferred, approved by locksmiths, secure-by-design. Ultion is simply the industry’s choice.

Ultion 3 Star PLUS is designed to stop the most common type of cylinder attacks: snapping, picking, bumping, and drilling. It features Lockdown Mode (which activates if someone tries to snap the cylinder), a molybdenum core for extreme drill resistance, anti-pick pins, and anti-bump technology. It exceeds TS007 3-star requirements and has been tested to over 750,000 cycles which is 7 times longer than the industry benchmark.
Lockdown Mode is Ultion's unique anti-snap technology. If someone attempts to snap the cylinder, instead of breaking and exposing the locking mechanism, Ultion locks solid. The internal mechanism seizes, preventing any further access. It's an active defense system, not just a sacrificial cut.
