How to Replace a Front Door Lock
You’re concerned about security. Perhaps you lost track of a key and are worried about it having fallen into the wrong hands - or your lock has been damaged in a burglary or attempted break-in. You may have discovered that your current lock isn’t particularly robust, or you’d like to implement new technologies like keyless entry. Whatever the reason, you’re thinking about a replacement. Here are some things to consider before you jump right in and some tips in case you decide to take the plunge.
Replace your Front Door Lock or Rekey?
Lost your key? Worried about who might have a copy? Before you replace a lock, find out if it can be rekeyed. Rekeying means that you leave your existing lock in place, changing the way it will be unlocked instead of replacing the entire locking system.
If you have a master-keyed system in which one key unlocks all your door locks, there’s a good chance it can be rekeyed instead of replaced. A locksmith will know whether rekeying is an option, so if you aren’t sure, check it out. Assuming that rekeying isn’t an option, here are some tips for replacing a front door lock.
More of the Same or Make the Change?
If a lock can’t be rekeyed, changing it for a lock that looks the same but is opened with a different key can be a DIY job. You’re just popping out the old lock and using the same space to install a new one with the same design.
However, this might not suit you. For example, you might want to replace a single-point lock with a multi-point lock, or you might want to switch to keyless locks. In scenarios such as these, you aren’t just seating a new lock into the same space an old lock previously occupied.
You might end up with new hole sizes and positions, weakening the door as you adjust for these. And the finish might not look great. Unless you’re an expert DIYer, you might end up with a world of trouble on your hands. At times like these, we’d recommend using a locksmith to do the job.
How to Replace a Front Door Lock: Switching Like-for-Like
Changing a relatively straightforward type of lock for a new one with the same design isn’t too difficult. Get a new lockset matching your old mortice lock, rim lock, or cylinder lock. A screwdriver or allen wrench and a drill may be the only tools you need.
Simply loosen and remove the screws. With that done, you should be able to remove the lock, slot the new one in, check alignment with the strike plate, and screw it into place.
If you’re choosing the same make and model of lock, you may not need to change the strike plate. If there are slight differences, you will likely have to change the strike plate too. It should be included in your lockset, so that’s not a problem.
Should You Choose a Different Type of Front Door Lock?
If you’d like to go further than installing a lock with a new key, you can improve your home’s security by choosing advanced locking systems. With this in mind, you might want to compare the various options out there.
Mortice locks are mounted flush with the doorframe. They are easy to maintain but rather difficult to install. Unless they conform with BS3621, 5-lever locks are not very secure and can easily be broken through drilling. 3-lever locks are even easier to bypass and will not conform to security standards.
Key operated or keyless multipoint locking systems have several bolts that engage with the door frame. They are much more difficult to break open and offer a higher level of security. However, not all these locks meet security standards, so check their certification.
Rim automatic deadlatch or nightlatch locks are fitted to the inside of the door with a keyhole on the outside. These locks are not particularly secure and are generally used in combination with another lock.
Euro cylinder locks are used with multipoint locking systems and are among the most common types of front door locks these days. Security is variable, so be sure to look for certifications.
The most secure locking systems are standards-compliant multipoint locking systems. Because they secure the door at several points, they can withstand brute force without breaking. Certifications indicate what other forms of attack or tampering your lock may resist. In general, you should opt for professional installation when changing to a multipoint locking system.
Replacing Front Door Locks: The Risks
There are good reasons why you should think twice before deciding to change door locks yourself. The first, and perhaps most obvious of these, is that just about any DIY task is more complex than it looks.
Apart from the task taking longer and being more complicated than you might have expected, you might damage the door, compromising its strength. So, even if your lock fits perfectly, the door itself becomes the weakest link.
If you do decide to change locks yourself, a like-for-like change would be the simplest option. However, you can still make mistakes, and you won’t be able to upgrade your home’s overall security in the process.
Looking to Upgrade Your Security? Doors, Door Frames, and Locks are Equally Important
