Are you worried someone could snap or force your door lock?
If your lock does not meet modern security standards, your home could be at risk. This is true even if the door itself looks strong.
At Stephen Fretwell Locksmith, we recommend Ultion anti-snap door locks. They are among the top security upgrades for homes across South Yorkshire and North Lincolnshire.

Most burglaries do not involve smashed windows or forced entry.
Instead, they often begin at the front or rear door with minimal noise.
If someone can snap, drill, or pick a lock with little effort, it becomes the weakest part of the property. Because of this, upgrading the lock is one of the smartest and most cost-effective security upgrades you can make.
Ultion locks stop the most common burglary methods used today.
Our standard recommendation is the Ultion TS007 Alps three-star plus cylinder.
Ultion cylinders are designed to handle modern threats. They are also tested against real-world attack methods. Many standard door locks are not.
✓ 11-pin internal locking system (stronger than standard 5–6 pin locks)
✓ Almost 300,000 unique key combinations
✓ Exceptional resistance to picking and tampering
✓ Designed to counter modern burglary methods
✓ The chance of another key matching yours is low
This is not cosmetic security. Instead, it is genuine mechanical protection.

Lock snapping is one of the most common burglary methods used today.
It usually starts with someone breaking the door handle. This exposes the lock cylinder. The cylinder is then snapped at its weakest point. Many older or low-quality locks can fail in seconds.
Ultion builds locks to stop this type of attack.
✓ Strong molybdenum core (around 25% denser than iron) ✓ Designed to resist snapping, drilling, twisting, thermal attack and forced entry ✓ Defeating it requires significant effort ✓ Forces intruders to waste time and create noise
Ultion locks include an intelligent lockdown mode.
If the lock detects an attack, a spring-loaded pin activates. This locks the central cam in place. As a result, someone cannot turn the lock. This remains true even if someone damages part of the cylinder.
Once the lockdown triggers, the lock remains secure.
This is practical, real-world protection — not a gimmick.
