The main reason homeowners request an Ultion cylinder upgrade is protection against lock snapping. Lock snapping is a common burglary method used against inadequate cylinder lock systems found on many uPVC and composite doors.

Ultion cylinders are specifically designed to stop this attack. When someone attempts to break the cylinder, the lock activates Lockdown Mode, a built-in security response that blocks the internal mechanism and prevents intruders from gaining access.

Inside every Ultion lock is an extra-strong molybdenum core. This core is 25% denser than iron, making the cylinder incredibly tough and resistant to forced entry. The strength of the material adds another layer of physical security against drilling and snapping attempts.

The lock also features a 20-point drill protection system, designed to stop intruders using power tools to gain entry. Combined with anti-pick and anti-bump technology, these features create what Ultion describes as an anti-everything cylinder.

Because of these features, Ultion locks are widely recognised as some of the most reliable high security locks for protecting homes against break-ins.

Sold Secure Diamond and Police Preferred Security

Ultion cylinders have achieved the Sold Secure Diamond certification, which is one of the highest security ratings for quality locks. The Sold Secure Diamond standard is awarded after rigorous testing designed to simulate real burglary attempts.

The locks also meet police preferred specification security requirements, giving homeowners confidence that the product meets recognised security standards.

Another important rating is the TS007 3-star certification. This means the cylinder provides strong protection against snapping and other attack methods commonly used against standard locks.

Ultion locks are also recognised by locksmiths and security professionals. Many consider them locksmith-approved due to the combination of advanced materials and practical installation design.

With these certifications, Ultion cylinders are widely used to upgrade older locks that do not meet modern insurance company security requirements.

There are many great aspects about Ultion locks. Here are just a few examples:

• Replacing an Ultion lock requires a screwdriver and accurate measurements (you can change it yourself in the future if you know what you’re doing, no special tools needed).

• Ultion locks have an 11-pin cylinder, which provides a higher number of key combinations for enhanced security.

• Ultion locks are recognised as police preferred specifications and meet high British Standards for security.

• For maximum security, the lock should not protrude more than 5mm from the handle.

• Only specialised, non-oil-based lubricants should be used on Ultion locks to avoid damage (you don’t need to go as far as to buy branded Ultion lock lubricant).

This all means that professional locksmiths in London(like ourselves) can provide same-day service and fitting for Ultion locks.

Security does not stop with the lock itself. The Ultion key control system is designed to prevent unauthorised duplication of keys.

Each lock comes with registered keys, meaning copies cannot be made without proper authorisation. This adds an important level of control for homeowners, landlords, and business owners.

Additional extra keys can be ordered when required, and multiple cylinders can be matched so they operate using a single Ultion key.

Ultion locks are also compatible with modern systems such as Ultion Nuki smart lock technology. This allows homeowners to combine mechanical security with digital control features.

For properties that require the highest level of protection, Ultion cylinders can also be paired with great multi-point lock door systems to create a fully protected entrance.
