4 things you should know before changing the lock on a door

Whether you want to change the lock on your front door to reinforce the security of your property or because the existing lock is damaged, having a clear idea of the options available to you will help you make the right choice.

Here are four elements you should consider in order to ensure your success when changing a lock!

1. The basic criteria for finding the right lock

While changing the lock on a door may seem mundane, you should be aware that not all locks are suitable for all types of doors. Before purchasing a lock, it’s important to consider certain technical aspects, such as the following:

  • What size was the previous lock?
  • What are the dimensions of the elements of the current mechanism (the locking points, cylinder, knob, etc.)?
  • How thick is the door?
  • What are the materials used in the door panel?
  • In which direction does the door open?

Are your locks in good condition but you’d like to increase the security of your home or commercial building? Here’s a factor you’ll want to consider during your search. The fact is that not all locks offer the same degree of protection. Therefore, being familiar with the requirements of your insurance company in that regard could help your find the most appropriate lock.

2. Should you replace a single part or the whole lock?

If your lock is malfunctioning, it may be that only one of the components is to blame. If so, it’s possible to replace only the part in question. Do you only want to change the key? Replacing just the cylinder represents a simple, economical solution. If that’s what you want to do, you have several different options, including a disengageable cylinder, which allows you to open the door even if there’s a key inserted in one side of the lock.

However, if you’ve decided to change your locks to reinforce the security of the premises, it won’t suffice simply to replace the cylinder. The best course would be to opt for a model of lock that features multiple locking points, thus providing optimum security.

3. The different types of door locks

Even though most people know that door locks are essential for ensuring the security of their home, not everyone necessarily knows the different types of locks that are available on the market. Choosing the appropriate door lock is extremely important, especially since certain types of locks are better than others, depending on the situation.

This is why it’s useful to have some basic knowledge regarding the subject. You’ll have a clearer idea of the best locks to choose so you can sleep soundly at night.

Common models of residential locks

Deadbolts

Very popular in residences and commercial spaces, deadbolts consist of a full metal cylinder with a flat end. You lock and unlock the deadbolt with a key on the outside or by turning the twist knob on the inside.

Push-button locks

Easy to install, a handle or knob with a push-button lock is activated by a key on the outside and a button on the inside. This type of lock is especially popular for use in front doors, sheds and certain rooms of the home, including bathrooms, offices and attics.

Cylinder lever locks

Used primarily in businesses, cylinder lever locks are somewhat similar to deadbolts. Although they’re easy to use, these locks are generally better for interior doors than for exterior doors, as they unfortunately offer little resistance to anyone trying to force them open.

Mortise locks

While it isn’t unusual to find locks of this type in residences, they’re much more common in commercial spaces. The locking mechanisms are built in to the door, itself. The main components are a threaded cylinder and a cam lock. Known for their resistance, mortise locks are among the most reliable locks on the market.

4. Which locks are the most secure?

If your priority is to reinforce the security of your residence or building, certain locks are more suitable than others. The available locks on the market fall into three different categories according to their quality. Of the three grades of locks, Grade 3 is the least expensive. Grade 2 locks are of better quality, while Grade 1 locks offer the best possible protection.

Are you looking for the most secure lock? You might want to think about replacing your current lock with an electronic lock. Used primarily in stores and other types of businesses, they have become increasingly popular in residences.

Electronic locks: relying on technology for reinforced security

You can combine an electronic lock with a conventional lock or you can get one as part of a complete system. The electronic locks available on the market function in various ways. You’ll find locks that use a keypad, a wireless signal, an internet connection or finger print technology (biometrics).

Electronic locks (or smart locks) offer numerous benefits to anyone looking for an easy-to-use high-performance system.

The advantages of electronic locks include the following:

  • They’re suitable for business and residences
  • They’re versatile, with a vast selection of options
  • You can modify access as you wish
  • You can combine them with an alarm system
  • They offer enhanced protection
  • You can operate them remotely
  • They simplify key management
