GCD Security Locksmiths have an unrivalled knowledge of & access to, a wide range of locks.

Locks have been around for over 4000 years & have been developed & improved by some great locksmiths who have become household names without even trying!

Jeremiah Chubb patented his first lock, the detector lock, back in 1818 & formed the now famous Chubb Company 2 years later with his brother Charles in Wolverhampton, then the lock making capital of Great Britain.

Linus Yale Senior, the inventor of the pin tumbler lock in the USA in the 1840s also formed a lock manufacturers company with his son. These two great lock producing companies still have locks on many of the world’s front doors & ironically now are both owned by one giant lock company, the conglomerate Assa – Abloy.

• Our own engineers have between them some 60 years experience of identifying the type of lock most suited to a particular application. They are also able to source a replacement for your damaged lock or offer an alternative should yours be obsolete.
• Adequately locked doors and windows provide the first line of defence for your premises and we can offer a wide range of door and window locks available for both wood, metal construction & composite doors such as UPVC.
• It is recommended that all entrance doors are fitted with a mortice lock. mortice locks provide greater front, side, and back door security by being "morticed" into the door itself. A mortice lock is therefore less vulnerable to ram or forced attack than a surface mounted lock. We fit mortice locks that are certified to BS 3621 and which can be identified by the British Standards kitemark symbol.
• We can supply cylinder operated mortice deadlocks & most of our locks have the facility to be keyed alike, which means to make a number of locks on the same key.
• Cylinder rim locks are fitted to the surface of the door and are used primarily as a convenient security lock for front doors and can also be used for back doors.
• Window locks secure the window to the frame by a simple bolt or clasp operation. This means that forced entry can only be made by breaking all the glass in the window and climbing through. The time it takes to do this, the noise it creates, and the prospect of injury is often enough to deter the opportunist burglar, yet fewer than 5 out of every 10 households have fitted window locks.
• We stock Lock manufacturers such as; Bramah, Union, Legge, Asec, Willenhall, Lowe & Fletcher, Era, Cisa, Briton, Ingersoll, Evva, Wellington, Adams-Rite

• There are two basic designs of padlock, open shackle and close shackle. Open shackle padlocks are the more familiar design where the looped shackle is exposed. Close shackle padlocks have concealed shackles which make them less vulnerable to cutting or sawing attack.
• We stock Padlocks from suppliers such as Kasp, Abus, Burg Wachter, Masterlock, Abloy, Chubb, Ingersol, Squire, Asec, Cisa, Evva & Era.
