Lock Fitting Locksmiths

There are a number of reasons why you may want to change your door locks. For example, you may have lost your keys and be locked out, believe someone has a set of keys who is not authorised to have them, have a broken or faulty lock, or be concerned that your existing locks do not provide the level of security you want. There is a wide range of locks available, including options suitable for DIY fitting and higher-security locks that may be better installed by a locksmith.

Types of Locks

The main types of lock associated with timber doors are cylinder rim locks, often referred to as Yale-style locks, and mortice locks, sometimes referred to as Chubb-style locks. Many home insurance policies specify minimum lock standards for external doors, so it is worth checking your policy before choosing a replacement. Five-lever mortice locks that meet BS3621 are commonly used for this purpose.

uPVC doors are generally fitted with multi-point locking systems. The number of locking points varies depending on the door and lock design. Over time, movement in the door or frame can affect how the lock operates, which may require adjustment or repair. If a replacement lock is needed, the correct type must be identified before fitting.

If the problem is simply lost keys, replacing the cylinder may be sufficient. If the multi-point lock itself is faulty or damaged, the locksmith may need to identify the exact mechanism before ordering a replacement. This can sometimes require a second visit. Window locks are relatively inexpensive and key-operated locks can be fitted to many types of windows, particularly those that are easily accessible from outside.

Door Locks

External doors are an important part of home security, so suitable locks should be fitted and maintained. Depending on the door type, a locksmith may recommend options such as a five-lever mortice lock, night latch or multi-point locking system.

A mortice deadlock can provide an additional locking point on a timber door and can only be operated with a key. The most suitable lock will depend on the type of door, frame and existing hardware, as well as any requirements set by your home insurance provider.

Cost of Replacement Locks

Replacing the barrel in a Yale-style lock can sometimes be carried out as a DIY job and may only take a short amount of time. A replacement cylinder and keys can be relatively inexpensive, although the cost will depend on the type and security rating of the lock. If you hire a locksmith, labour and callout charges will also apply.

Replacing the entire lock will usually cost more, and multi-point locking systems fitted to uPVC doors can be more complex because there are many different designs and mechanisms available. If a burglary or attempted break-in has damaged the door or frame, additional repair or replacement costs may also need to be considered.

Choosing a Locksmith

Before hiring a locksmith, compare several local options where possible and ask for a clear written quote. Check what is included in the price, such as labour, callout charges, parts and any additional work that may be required.
