The SheffLOCK Home Security guide gives you tips on how to best keep your home secure, such as improving door & window lock security, how sash jammers work to how a poorly fitted lock can lead to break-ins.

The main security advice for your home is to speak to SheffLOCK with regards to the security products that you have fitted to your doors and windows.

In terms of some general security advice we suggest:

Upgrade Your Door Handles

Upgrade Your Door Handles

Consider upgrading your door handles when you change your locks. Standard door handles offer little protection and can be broken in seconds.

We highly recommend that 2 star Lock Lock door handles are fitted with 3 star Ultion anti snap locks to provide you with 5 star protection. This is the highest standard of protection available.
3 star security standard

Upgrade your Locks to BS3621 British Standard

Have your home locks upgraded to BS3621, a standard which most insurance companies require your locks be fitted to.

BS3621 is a British Standard where locks are tested against common burglar techniques such as drilling and picking.

Locks that can be upgraded to BS3621 include Mortice Locks, Night Latches ( Yale Locks ) and Rim Cylinder locks.

If you live in a block of flats or apartment the standard BS8621 is recommended which allows anyone to exit in an emergency without needing a key.
