Door Locks
When it comes to home security, not all door locks are created equal. Knowing the different types of locks can help you decide. The main types of door locks are:
Mortice locks
Cylinder locks or a euro cylinder lock
Deadbolt locks
Smart locks
Mortice locks are built into the door, so they are a robust choice for external doors. These locks are hidden within the door and are very secure. The more levers a mortice lock has, the more secure it is; standard models have 2 to 7 levers. They’re suitable for wooden doors and have a hidden locking mechanism, including mortice sash locks.
Cylinder locks are versatile and can be used on all types of doors, timber, metal, and uPVC. However, they can be vulnerable to lock snapping, a common attack method. To combat this, anti-snap cylinders have been developed to increase the security of a euro profile cylinder lock. These locks are easy to change, so they are a popular choice for many homeowners.
Deadbolts are known for their high resistance to forced entry, often reinforced with hardened materials for added security.
Smart locks are the latest innovation, using technologies like WiFi or Bluetooth to offer features like smartphone control and real-time alerts. These locks offer convenience and security, so they are a great option for tech-savvy homeowners.

Tools Needed to Change a Door Lock
Changing a front door lock doesn’t require a whole toolbox; the right ones will make the process smoother. You’ll need screwdrivers, pliers and the original cylinder lock key. These basic tools will cover most tasks.
To remove a cylinder lock, you will need a Phillips head screwdriver and a flathead screwdriver. An Allen wrench may also be required.
How to Choose the Right Replacement Lock
Choosing the right replacement lock is key to home security. A wooden door may need specific locks like mortice deadlocks, sash locks, and night latches. Look for locks that meet British Standards, as insurance companies often require them, particularly on external doors.
Locks that meet British Standard BS3621 or are Kitemarked will offer sufficient protection and meet insurance requirements. Accurate measurements and correct positioning of the lock are key to security.
A locksmith can advise you on the best locks for your door and security needs. An expert can guide you through the options to choose a lock that offers security and convenience.
How to Change a Lock - Before You Start
Preparation is key before changing locks. Get all the tools you need, including a new lockset, screwdriver, tape measure, and pencil. Having everything ready will save time and make the process smoother.
As a quick guide, ensure the door is unlocked before attempting to remove the old lock. Ensure the door hole is the correct size and aligned with the lock mechanism. Follow the manufacturer’s instructions to avoid installation mistakes and ensure security.
Euro Cylinder Locks
Remove the screw holding the euro cylinder lock in place. This will be on the side of the door aligned with the lock itself. Insert the key into the lock, turn it to align the cam and gently pull the lock towards you.
Push the new cylinder in to insert the new lock. Turn the key to rotate the cam within the cylinder. Replace the fixing screw once the new cylinder is in place.
Mortice Lock or Mortice Sash Lock
When replacing a mortice lock, you need to be careful. Start by removing the screws from the faceplate. Turn the key to engage the bolt, and pull the lock out by hand. Pliers can pull the lock out if it is too stiff.
Insert the new lock into the mortice once the old lock is removed. Position the faceplate and screw it in with the provided screws. This will ensure the lock is in place and ready to use with your new house keys.
You may also need to change the strike plates on the other side of the door frame.
Night Latch
Night latches are single point locking mechanisms fitted against the inside of most wooden doors. When replacing a nightlatch, buying an exact like-for-like is strongly recommended. Once acquired, unscrew all retaining screws from the nightlatch to allow it to be removed. Once removed, place the new nightlatch where the old one was, and screw everything back together as it was before. If any screws are missing, it is highly recommended to replace them, too, as a loose night latch can compromise security.
Rim cylinder locks
A rim cylinder is almost always found paired with a night latch. It is a circular cylinder in which you insert the key upside down. When changing a rim cylinder lock, you first need to remove the night latch on the other side of the door, as it covers the retaining screws for the rim lock. Once done, there should be two retaining screws, which, when undone, will release the rim cylinder. You may replace the old with the new and fit everything back together.
Lock Replacement Safety
Be safe when replacing locks. Get all the tools and work in a well-lit area to avoid mistakes.
Don't over-tighten the screws as that will prevent the lock from working. Fitting the correct size lock is key.
Test Your Door Lock
Test your new lock after installation to ensure it’s working smoothly. Use the key to ensure it’s smooth. Make sure the key turns and that the bolt engages and disengages smoothly without resistance, and test on both sides.
Regular checks on the lock will prevent future problems. This will ensure your new lock is secure.
Reasons to Change Your Locks
There are many reasons to change your existing lock. High security locks, like British standard locks, make your home less appealing to burglars, reducing break in risk. Modern locks, like smart locks, offer keyless entry and real-time alerts, security and convenience, but are more expensive and cause more significant problems when they fail. This also addresses unauthorised access from ex-flatmates or terminated employees. Modern high-quality locks can reduce home insurance premiums by improving security. You may also need to change the lock if you have lost your keys.
When to Call a Local Locksmith
Although changing locks can be a DIY job, sometimes you need to call a professional locksmith during normal working hours. If unsure about the installation, professional help is safer. Locksmith costs can vary from city to city. A professional installation ensures proper fitting and functionality, which is important for the lifespan of the lock. This may save you from paying for an emergency locksmith, as emergency locksmith costs can be much higher. Most local locksmiths will be able to change door locks for you, and depending on how many locks and keys are required, it may save you a lot of time and effort.
Are you locked out of your home or office? Call a locksmith as soon as possible to get back in safely. Lock malfunctions, like a stuck lock, usually require emergency locksmiths to inspect and fix or replace the mechanism.
Aftercare and Maintenance of New Locks
Proper maintenance will keep your new locks working and secure. Regular cleaning and lubrication will keep the locks in good condition. Keep the area around the locks clean and clear of dirt and debris.
Suitable lubricants for the material and finish will extend the life of the lock. Regular lubrication and not slamming the door will extend the life of the lock.
