Security standards

SM4 Locksmith Morden are careful to install the most secure locks available.

The following information is important about marking security products that demonstrate that the products meet recognised security standards:

  • Security testing of doors, windows and locks is handled by the British Standards Institution (BSI).
  • Security testing of doors, windows and locks is handled by the British Standards Institution (BSI).
  • The British Standard number you need to look for is BS3621.

The technical specification shows it meets all the security standard requirements that protect against all known methods of forced entry, which is what TS007 stands for in terms of replacement cylinders and protective door furniture.

The BSI has adopted a new standard for smart locking devices, TS621:2018.

Standard insurance locks

The BSI has adopted a new standard for smart locking devices, TS621:2018. However, most insurance companies require the BS3621 standard.

Types of lock

In addition to providing and installing numerous types of locks, we also offer service to:

Sash locks

The door is morticed with a sash lock. It has a deadbolt that locks the door as well as a built-in latch so that the door will remain closed without having to lock it.

Dead-locks

The door is also morticed with a dead-lock. There is only a deadbolt with no latch on this door, and it is often seen on older doors.

Rim locks

As opposed to a mortise lock, a rim lock is screwed into the door rather than being morticed in. Rim locks are often applied to doors that are too thin for a mortise lock.

We stock a variety of reputable brands including the popular Chubb and Yale brands.
