It is of paramount importance that all doors are secured to a sufficient level in order to prevent unwanted intrusions into your home.
Installing locks properly is often an arduous and time consuming task. That’s why the Handy Squad has a team of highly-skilled Locksmiths, to ensure security concerns are a thing of the past. They will be able to fit, change and repair any locks with ease.
The two most popular types of lock for entrance doors are the mortice lock and the cylinder rim lock.
In order to open a mortice lock, you will need to insert a key from both the inside and outside of the door. This is most commonly referred to as a deadlock.
Mortice locks are typically equipped with 2 to 7 levers. The difficulty of picking mortice locks will increase as you install more levers to the mechanism. In the case of entrance doors, you will be required to have a mortice lock with five levers.
A majority of mortice locks come in a standard size. You also have the option of replacing old mortice locks as long as the distance between the door edge and handle are the same.
On the other hand, cylinder locks are highly beneficial for people moving house since they can be installed and replaced with ease. They simply slot into place and come in a variety of different sizes.
Cylinder rim locks that use a deadlock will have a key for the outside and a key operated knob for the inside. The key used for internal use will provide the option of a deadlock system. This basically means that the door cannot be opened if someone smashes the glass in the door and attempts to turn the knob.
It is suggested that cylinder locks and five-lever mortice deadlocks should be fitted 45-60cm apart in order for them to be effective.
Mortice door bolts have the option of being fitted onto the edge of doors. The best way to maximise security is placing one close to the top and one close to the bottom of the opening edge on the door.
There are a number of useful supplements to increase security, which includes: door limiters, security chains and surface mounted bolts. All of these are simple to install and are guaranteed to provide long-lasting quality results.
Many uPVC doors run the risk of damage from retro-fitted security systems. If you have any concerns about the types of locks that are appropriate for your door, you should always contact the manufacturer. If you have a modern door in place, you will most certainly have a multi-locking system already in place.
Any doors which have glazed panels should be equipped with a deadlock since they don’t possess the same structural integrity as solid doors. You should consider replacing any glass panels with either laminated or toughened glass.
Finally, patio doors are commonly used by thieves, which means you should consider installing extra locks. The best options for this type of door is push-to-lock or key-to-open, since they are simple to use and will fit perfectly within a frame.
How to fit a mortice security bolt
1. You firstly need to mark out the position of the bolt within the door edge. Then drill a hole with the same depth as the door bolt.
2. Insert the bolt and then mark a clear line around the outside perimeter of the end plate. This can now be used as a guide for chiselling.
3. Using a chisel, you then need to carefully take away enough wood in order for you to fit the door bolt end plate in a flush manner.
4. Using the chiselling as a guide, hold the bolt up against the inside part of the door and make an accurate marking to position where the keyhole will be placed.
5. Then drill a hole in accordance with the depth of the door. You need to ensure that you don’t drill all the way through the door.
6. In order for the bolt to be installed securely, you firstly need to drill a series of pilot holes for the fixings. The most suitable sized drill bit would be 2-3mm. You will then be able to slide the bolt into place and fix securely.
7. You can now drill the required pilot holes before fixing the key plate into its place. You must ensure that the plate has been aligned correctly with the keyhole.
8. Finally, you need to check that the key works properly.
How to replace a five-lever sashlock
1. You firstly need to remove the handle that is placed on the inside. This is done by unscrewing all of the retaining screws that are holding the handle in its place. You can then place the handle onto one side for reattachment at a later time.
2. Then remove the spindle bar that fits through the lock as well as both handles. Once removed, make sure you place them to one side as they will be reinserted later.
3. All the screws that secure the lock then need to be removed. It is possible that you may need to push a screwdriver through the spindle hole to help release the lock.
4. The replacement lock can now be screwed and fitted into position. If you have difficulty putting the lock into place, you will need to chisel away any excess wood.
5. Finally, you can now reposition the spindle as well as the inside handle. You must ensure that the new lock works methodically and engages with the strike plate in an effective manner.
How to replace a cylinder lock
1. You firstly need to remove the body component of the lock. This will need to be fitted back into place once the new lock has been installed.
2. Then unscrew both retaining screws that go through the door and keep the cylinder component of the lock in its place. You also need to ensure that the mounting plate remains in position.
3. You can now remove the old cylinder from the outside. Once this is done, slide the new cylinder through the drilled hole and refit using long screws.
4. The lock body can now also be re-installed. If the connecting bar exceeds the required length, you will need to remove the lock body and cut down the size of the bar with a hacksaw.
5. Finally, once you are certain that the lock body has been securely put into position, you will need to ensure that the door opens and closes smoothly when operated with the new key.
