Anti Snap Locks

3 star TS007

Lock snapping burglary is a prolific method of entry that has been used by criminals for over a decade.

It is believed that this method originated in the West Yorkshire area of the UK sometime in 2007 and quickly spread throughout the country.

The method targets inadequate euro locks and UPVC handles on doors such as composite, UPVC, Patio and french doors to name a few.


Why Choose Us

Year on year statistics and our own personal experience as former Police officers has shown that burglars commit this method of entry at all times of the day, whether persons are in the property or not due to this method of entry being relatively quiet and scarily quick to commit.

On many occasions, if the offence is committed whilst people are asleep in bed, they awake to discover that they have been burgled but unfortunately heard nothing.

As a burglary prevention company we attend lock snapping burglary scenes routinely as the majority of homes and businesses are still unaware of the dangers of non-accredited euro locks being installed.

Layered Protection

The unfortunate reality is that inadequate locks and handles are fitted as standard to the majority of doors installed everyday, who are unaware of how vulnerable to burglary they are.

Clean Design

If your euro lock does not display the accredited 3-star and diamond stamp mark underneath where the key goes in, it is a fact that the lock can be snapped and entry gained.

Cutting-edge Features

This is proven time and time again as we attend burglary scenes whereby so called anti-snap locks that are not accredited have been snapped and entry gained.

About Our Lock Fitting Proccess

Standard UPVC handles are only on average approximately 3 x the thickness of a coke can and are also usually made of aluminium which is snapped extremely easily.

The maximum accreditations available for a security handle is TS007 2 star diamond accredited.

Can this method of entry be prevented?

100% this method of entry can be prevented by installing the TS007 3-star diamond accredited ULTION euro lock from SheffLOCK.

This lock has never been snapped and entry gained.

Atempted break-in

After an attempted break-in via snapping my euro cylinder lock, ShefLOCK turned up within two hours (I'm based in east Doncaster) and fitted Ultion Locks and secured by design handles. Very thorough with their explanations and careful with installation including cleaning up after themselves.

Burglary Prevention Advice

We often speak to customers who were victims of a burglary over 20 years ago, who remember the details of such an incident, recalling what an awful experience it was and wanting to do all they can to prevent such an event occurring again.

The facts are that Burglary is and always will be a real concern for all of us. We started SheffLOCK as a burglary prevention company because we knew that the vast majority of victims of burglary and the public as a whole are receiving either completely wrong Burglary prevention advice, outdated information or simply not receiving any advice what so ever.
