The lock plays an essential role in the security of your home or business. However, there are several types of locks designed to meet different needs and preferences. Are you looking to replace a lock or simply want to better understand the various mechanisms? Browse our guide.
The main types of key locks
Cylinder lock (or barrel lock)
The cylinder lock is the most commonly used on residential entry doors, belonging to the category of deadbolt locks.
What is a deadbolt lock? It is simply a bolt operated by the key, without using any spring to drive the cylinder. The cylinder lock consists of a barrel (cylinder) and pins. The key must have specific cuts that align the pins perfectly to allow the cylinder to turn. If the key is not correct, the pins cannot rotate the cylinder.
This type of lock is appreciated for its simplicity and value for money.
Rim lock
Less common nowadays, the rim lock operates thanks to grooves (pins) that block or release the mechanism by moving within the cylinder. It requires a specific key that pushes the pins upward to a precise position. This lock continues to be used today for its retro charm.
Bar lock
In the bar lock, you find pistons, key paths, and a bar; the pistons are equipped with springs that maintain tension. The key used has cuts that push the pistons; they then push the bar to allow unlocking. It is also known as a “security lock,” as it is often employed to secure safes.
Multipoint lock
What is a 3-point lock? It is a system that secures the door at multiple points to enhance security. Generally, the multipoint lock offers 3 to 5 locking points for better anchoring. It is, therefore, more difficult to force the door open, for example. This lock is particularly well-suited for armored doors.
Other types of locks used for residential security
Surface-mounted lock
Fitted directly on the door, the surface-mounted lock is ideal for certain older doors or those that cannot accommodate a cylinder lock. It is an easy-to-install and versatile lock, suitable, among other things, for thinner doors or gates. It is a reliable and sturdy option, though less aesthetically pleasing than other types of locks.
Mortise lock (or flush-mounted lock)
Integrated into the thickness of the door, the mortise lock offers a much more discreet appearance. In fact, it is practically invisible: only the end of the cylinder that receives the key is noticeable. However, this entry door lock is also more complicated to install and requires a certain level of expertise.
Sash lock
This type of lock is most often found on French doors (double doors) or doors with two panels. It is also suitable for patio doors. The sash refers to a vertical rod that moves up and down. Two rods connect the lock to its anchoring points, and the sprockets cause the sash to move when the door handle is operated. Easy to install and affordable, it is, however, not the most secure option.
How to choose the right lock for your door?
Desired security level
Not all locks offer the same level of security. The single cylinder lock, for example, provides adequate but quite basic security. Those with 3 or 5 locking points are often cited among the best door locks in terms of security.
Type of door and installation
You wouldn’t choose the same lock for a recessed sliding door as for a double door or a thin door. The standard hinged door generally accepts most locks, but you need to be especially cautious with the other types of doors.
Ease of use and specific needs
When choosing a type of lock, also consider ease of use and your specific requirements. Some models are more durable, while others deteriorate more quickly, such as the sash lock. Among the practical choices, electronic and connected locks can be an interesting option.
Budget and installation cost
The final and not least criteria is price. Some types of locks are more expensive, for instance, multipoint locks that offer enhanced security, or rim locks that feature an antique charm. Others, like the mortise lock, offer several advantages but may incur a higher installation cost. In general, the cylinder lock remains a popular choice for its value for money.
In conclusion, consider your door type, the desired properties, and your budget. Do not hesitate to seek advice from a professional.

FAQ
What is the difference between a multipoint lock and a single-point lock?
The single-point lock secures the door in one place, whereas the multipoint lock secures the door at several points (generally three or five), offering better resistance to break-ins.
Are connected locks secure?
Connected locks offer advanced features, but it is essential to choose models from reputable brands, keep the firmware updated, and use strong passwords to minimize hacking risks.
How can I enhance my door’s security beyond the lock?
Installing an armored door, adding anti-pinch angles, using reinforced hinges, and installing a peephole or a surveillance camera can improve your door’s overall security.
