Book a call-outWhen it comes to protecting your home or business, Ultion locks set the gold standard. Endorsed by the police and rigorously tested by British Standards and the Master Locksmiths Association, they are widely recognised as the most secure option for door lock upgrades in Barnsley.
Ultion has earned the prestigious TS007 three-star rating—the highest level of security certification. Its keys are also designed for strength, being 60% thicker and more durable than standard alternatives.

The Ultion WXM 3-star Plus lock features advanced technology that distinguishes it from its competitors. With 11 security pins and nearly 295,000 unique combinations, it is virtually impossible to pick.
Constructed with a molybdenum core that is 25% denser than iron, Ultion locks provide superior resistance to snapping, drilling, and bumping. If tampering is detected, the lock automatically activates ‘lockdown mode’, securing the central cam with a reinforced retaining pin to prevent damage. If you can’t turn the cam, you can’t open the door.
Another key strength of Ultion locks is their versatility. They are compatible with a wide range of doors, including uPVC, composite, and, in some cases, wooden doors. With professional installation by a skilled locksmith in Barnsley, you can enjoy maximum protection and peace of mind.

Manufactured from premium-grade components, Ultion locks are designed for long-term durability and provide reliable security for years to come.
In addition to providing peace of mind, upgrading your door locks ensures your property meets the security standards required by most home insurance providers. By replacing your current locks with Ultion locks, you’ll protect your home and maintain full insurance coverage.
