Anti Snap Locks

Anti snap locks guarantee that when you close your door and lock it, no person can break in to gain entry. This method of forced entry is known as Lock Snapping. It is important to know that this anti snap lock is designed to break at the cut point when enough force is applied. This disables the lock from whatever side has been attacked.

You can still use the lock as normal from the inside which still allows use of that particular door in the short term until the lock is replaced. Not surprisingly, no one has ever claimed the £1000 guarantee and Burglars continue to be unsuccessful in attempts to snap Anti-snap locks and gain entry into peoples homes and businesses.

An Anti-snap lock installed by SheffLOCK is proven time and time again to prevent Burglary.

Ultion Locks

Ultion locks come with a manufacturer’s £2,000 guarantee that it cannot be snapped and entry gained as a consequence. The TS007 3 star accredited Ultion door lock is fast becoming the number one choice for all upvc and composite door companies and is the staple for many householders who are conscious about home security.

Your door may look great, feel solid, and have a great multi-point lock, but what’s the point if it can be disabled in a few seconds via an inadequate cylinder lock.

As well as being approved by the Police and achieving the highest Kitemark star rating, Ultion locks are tested by locksmiths with the Master Locksmith Association and accredited with their highest standard, Sold Secure Diamond.

Ultion Keys

SheffLOCK are one of only a few official Ultion key centres in South Yorkshire and we strongly advise all households to have these burglary prevention locks supplied and fitted.

Only genuine Ultion keys guarantee protection. Counterfeit Ultion keys are a threat to your home security. The Ultion logo is your guarantee against broken locks and leaving you stuck. Your home is secured with a lock that has passed every security test. So, when it come to spare or replacement keys make sure you only use genuine Ultion keys. Counterfeits will damage your lock and invalidate your guarantee.
