Security Locks

We sell a wide range of home and office security products including window and door locks.

If we don’t stock the item you are looking for we can often order it at short notice, so please just ask.

Naturally as well as selling a range of security locks we can also offer a fitting service. We are always happy to give advice to help you make the right choice for your needs.

UPVC Door Locks & Handles

We carry out a lot of adjustments, repairs or replacement of locking mechanisms on UPVC doors. If you have a UPVC or Composite door and the handle or key seems to catch or is more difficult to turn than usual don’t ignore it! give us a call. If caught early it may only be an adjustment of the lock or keepers instead of needing us to open your UPVC or Composite door and replace the locking unit. Sometimes a minor adjustment of UPVC locking units can save a costly repair.

UPVC Door Locks

There are many manufacturers and variations of locks for UPVC doors. The locking mechanism inside the door can have different styles of locking features i.e.

  • Rollers
  • Mushrooms
  • Shoot Bolts
  • Hook Bolts
  • Dead Bolts

Some of the older ones have been discontinued. Sometimes the cylinder which drives the locking mechanism can be faulty.  

We will ask a few questions before coming out to you so that we can identify the type of locking unit. This will save us time but more importantly it will save you money

We carry a wide selection of door locks in stock. However if we have not got one we can usually get it within a couple of days. If the door lock is discontinued we have a lot of experience in finding you the nearest replacement.

Mortice Locks

2 and 3 lever sashlocks and deadlocks generally provide a low level of security and so they are usually only installed on internal doors. They will sometimes have a key number on the key as there may only be 30 different keys to a particular make of lock. These locks are also available with rebate sets for double doors, but 2 and 3 lever locks should never be installed on any external door.

5 lever mortice sashlocks and deadlocks are operated from both sides with keys, the sashlock having a latch and handles where a deadlock is key operated only. There are 5 lever locks which do not comply with current insurance requirements and 5 lever British Standard locks to the new British Standard BS3621 2004 that have a 20mm lock bolt.

Door locks - Mortice Lock

All locks fitted to external doors should meet or exceed BS3621 to comply with current insurance policy requirements. If there is a need to fit a lock on a set of double doors this can be done by using a rebate kit supplied independently to the lock. 

We stock 5 lever locks from Chubb, Era, Union and Legge. We are able to “key alike” many of the locks from these ranges in our shop.

Mortice Latch

The mortice latch is not a security lock in itself; the main purpose is to hold a door closed against a breeze or wind. Mainly these are the tubular style but other styles are available, these are fitted to wood internal hinged doors with a pair of latch handles but can also be fitted to double rebated wood doors also.

Rim Mortice Locks

Rim locks are locks which are fitted to the inside surface of the door and lock into a box keeper fitted onto the frame. These locks provide very little security but they are widely used on sheds, outbuildings and older properties. 

We stock a range of Rim Locks and can also make keys to older locks already fitted to properties.

Oval & Euro Cylinder Sashlocks And Deadlocks

Cylinder sashlocks and deadlocks give a wider scope of options for the customer as you can choose a cylinder lock case to suit your requirements and then add the cylinder type you require i.e. a standard cylinder key or a registered key cylinder such as Ultion or ABS. You can then choose the door furniture you require, such as brass or aluminium.

Oval & Euro Cylinders

You can buy both products in 3 different formats; Single Sided Key, Key and Thumbturn and Double Sided Key.

Euro Cylinder
Euro Cylinder

These types of cylinder are a component and used in conjunction with a mortice lock case. While the oval cylinder is more common on Aluminium doors, it can be found on wooden doors as well. However the same can be said for the Euro style cylinder.

Both products are standard dimensions in size except for the length i.e. one side to the other, the length can be equal measurement but many are offset especially on UPVC doors. You can replace these door locks yourselves but it is important to know the size when replacing the cylinder. To get the exact measurement you need to remove the cylinder from your door. You then need to measure from the end of the cylinder to the centre screw hole on both sides and this will give you the split measurement i.e. 35 – 45.

We stock a large range of cylinders to suit your needs and security requirements. We provide a service to change these locks for you if you are unable to do so yourself. The oval cylinder is available on different key sections. (The oval does not have the anti-snap, anti-pick and anti-bump facilities.)

The euro cylinders are more widely used than the oval cylinders, especially on UPVC and Composite doors. The security level of the euro cylinder varies from a standard 5 or 6 Pin key to a high security patented key giving added protection.

UPVC and Composite doors have increased in popularity and have multi-point locks giving extra security. However the cylinders on these doors are the weak point and burglars have found they can snap the cylinders and get in easily. There are a range of cylinders available to help solve this problem.

Ultion and ABS have a range of 3 Star Kitemark cylinders that have anti-snap, anti-pick and anti-bump with the added bonus of a dimple security key. Both Ultion and ABS cylinders are available either key both sides or with a thumbturn on the inside and can be keyed the same as another cylinder on your property.

Rim Cylinder Nightlatch

The rim cylinder nightlatch is the name given to the traditional style “Yale” locks. The body of the lock is fitted on the internal surface of the door which is then operated by a rim cylinder which passes through the door to the lock body.

Rim Cylinder Night Latch

Most of the rim cylinder locks are designed to fit a single leaf wood door, but some can be adapted to fit a single leaf outward opening door, and also double leaf doors. These locks can be keyed alike; master suited, and is also available on a patented key system.

Rim cylinder nightlatches come in many makes, designs and options from a basic Yale 77 nightatch to the Yale PBS range of high security deadlatches which comply with insurance BS3621 requirements.

A standard nightlatch should always be fitted with a 5 lever lock on external doors as the nightlatch can easily be broken into if fitted by itself.

  • The Basic Rim Cylinder Lock – This is just a slam shut locks i.e. as you shut the door behind you it will lock.
  • The Outside Deadlock Rim Cylinder Lock – Close the door and then turn the key 360 degrees to deadlock.
  • The Square Bolt Deadlock Version – Close the door and then you have to lock the lock with the key otherwise the door will be open.
  • The Double Deadlocking Rim Cylinder Lock – On this version before you leave the house you open the door, lock the inside handle with the key, then close the door. The handle will then remain locked until released by the key from the outside or the inside. This version of rim cylinder lock is available in a British Standard Version.

Window Lock

Many of the factory fitted casement stay and fasteners on windows are designed to just keep the window closed, and these alone do not provide sufficient security to meet modern insurance requirements for many policy holders.

Insurance requirements for windows

The general advice given by both insurance companies and crime prevention officers is that all ground floor or first floor windows and patio doors that are that are accessible are fitted with key operated window or patio door locks. If you are in any doubt about the security of your windows or patio doors please do not hesitate to call us on 01604 713271 for help and advice.

Sliding Patio Doors

Sliding patio doors should be fitted with two additional key operated patio door locks as well as the standard centre lock. Patio door locks can be installed to all types of patio doors including wood and aluminium to help prevent both the forcing and lifting of the patio doors off of its track.

French Doors

French doors should be fitted with key operated security bolts to the top and bottom of both doors as well as the central sashlock which should be 5 lever British Standard lock to the new British Standard BS3621 2004. The key operated bolts are either cut into the top and bottom of the door, and all that is visible is the keyhole on the inside face of the door, or surface fitted bolts such as Era pressbolt or Yale 8K116. Standard non locking slide bolts should not be fitted to french doors as they are not strong enough and the doors can be opened by just releasing the bolts and pushing the doors.
