High-Security Anti-Snap Lock Upgrades in Oxfordshire

Ultion vs ABS: The Gold Standard in Protection

Not all “anti-snap” locks are created equal. To provide our clients with total peace of mind, we only install hardware that has achieved the prestigious Sold Secure Diamond rating. Whether you choose the technical innovation of Ultion or the proven reliability of ABS, you are investing in a lock designed to withstand the most determined forced-entry attempts.

Ultion 3-Star Cylinders

Features “Lockdown Mode”—a hidden firing pin that triggers when an attack is detected, securing the central cam. With 11 pick-proof pins and 294,000 key combinations, it is virtually unpickable.

ABS 3-Star Diamond Grade

The only lock with a unique “Snap Secure” technology that blocks access to the internal mechanism if the lock is snapped. Tested to TS007 3-star and BS EN1303:2015 British Kitemark standards.

Security Guarantee

Both Ultion and ABS are so confident in their engineering that they offer guarantees. ABS a free £2,000 and Ultion a free £5,000 security guarantees. If a burglar snaps the lock and enters your home, the manufacturer pays out.

One-Key Convenience

We can “suite” your locks so that one high-security key opens every door in your property, including the front, back, garage, and even garden gates.

Meeting Your Home Insurance Requirements

Many UK insurance providers now specify that uPVC and composite doors must be fitted with TS007 3-star rated cylinders to remain valid. If your property is burgled and you are found to have sub-standard locks, your claim could be rejected, payouts reduced, or your future premiums increased. It is also important to note that maintaining a faulty or damaged lock could invalidate your insurance, as insurers expect your security to be in full working order.

AJK Locks provides a comprehensive insurance-compliance service, auditing your current hardware and installing BS3621 (for timber doors) or TS007 (for uPVC and composite) compliant upgrades. For timber doors, we specialise in fitting 5-lever mortice deadlocks that carry the British Standard Kitemark, ensuring your security meets the elite benchmarks recognised by the police and security professionals across the UK. These upgrades not only guarantee your insurance validity but can also lead to discounted policy costs, providing total protection for your family and your assets.

Total Protection in Action: Ultion Lockdown Mode

Watch the Ultion 3-Star “Lockdown Mode” in action. If an attack is detected, a hidden internal pin instantly secures the lock, stopping intruders even if the outer cylinder is snapped. High-security engineering for your total peace of mind.

We provide high-security engineering across our six primary hubs, ensuring local expertise is always available to reinforce your property’s perimeter.
