Deadlock
A mortice deadlock is used on a timber door. It is fitted with in a pocket (mortice) inside the doors edge. This lock comes in different types, in order to fulfil all of your security needs. High security, insurance approved locks are available for final exit doors, and low security available for internal doors. A deadlock includes a single bolt that is operated by a key, and it can usually unlock or unlock the deadbolt from either side. There are pros and cons to a deadlock:

Cons: It’s not usually possible to use a deadlock as a stand-alone lock. A deadlock is usually used in conjunction with a latch, meaning you need two products to correctly close and lock the door.
Sashlock
The next lock is a Sashlock. A Sashlock is also used on timber doors and fits within a mortice inside the doors edge. Again, this lock has different features, there is low security available for internal doors and high security insurance approved locks available for final exit doors. A sashlock includes a deadlock and a latch within the same case. The key can usually lock or unlock the deadbolt from either side. Once again, there are pros and cons to a Sashlock:
Pros: A sashlock can be used as a single locking solution. The door can be closed and held in to place by the latch and the deadbolt with lock the door securely.
Cons: This type of lock needs to be used with a handle and cannot be used on it’s own.
Rim Lock
A Rim Lock is fitted to the surface of a door and is sometimes fitted to a gate or a bedroom or bathroom door. A Rim Lock includes a deadbolt to enable the door to be locked and in many instances, it includes a latch. Some Rim Locks can be fitted so that a key can be used from either side, but it is most common for the key to operate just from one side. The pros and cons to a Rim Lock include:
Pros: Easy to fit to the door without having to make a mortice. Relatively low cost.
Cons: Not designed for high security applications.
Night Latch
A night latch is fitted to the inside of a timber door and is used to lock a door, just by closing it. These are usually used on final exit doors as they are high security. The Night Latch includes a latch bolt which is opened by the key on the outside or by the thumbturn on the inside. Often, Night Latches include a snib button which can be used to hold the latch open.There are are pros and cons to the Night Latch:
Pros: Easy to close and lock the door. Can be used as a standalone lock if insurance approved.
Cons: Because it’s easy to lock, you can get locked out by mistake if you don’t have your keys with you. If it’s not insurance approved, you also need to install a deadlock to your front door.
Multipoint Lock
A Multipoint Lock is used on composite and UPVC doors where you typically need to lift the handle when leaving the house before you can lock the door. A Multipoint Lock usually includes a deadbolt and a latch in the center as well as a further 2-4 bolts/rollers that also secure the door in to place. The pros and cons of Multi Point Locks include:
Pros: With multiple points of locking, this type of lock is one of the most secure and that’s why it’s the most common type used on UK houses.
Cons: These can be tricky to install if you are installing one on a new door. If you are replacing and old lock, you need to be careful and get the measurements right.
Cylinder Door locks
A Cylinder Lock is always used with a lock case and is used to lock and unlock a door with a key. These are usually seen on door locks. As well as this, a Cylinder Lock can work with a Deadlock case, a Sashlock case and a Multipoint lock. Cylinders are available with either Euro or Oval profile. The Euro profile is the most common and will work with any lock that accepts a Euro profile cylinder. The lock includes a centre cam which turns, when used with a key and throws the deadbolt. There are pros and cons to Cylinder Door locks, which include:
Pros: These locks are usually held in place with one screw, making them very easy to change on a DIY basis.
Cons: Lock snapping is extremely popular with burglars who can snap lower security cylinders, to manipulate the door lock, and break in. It’s vitally important to buy an anti-snap cylinder if used on a final exit door.
