Locks and keys: understand and choose home locks

Many homes rely on external residential door locks as their primary home security system. Whether you are replacing a single lock or renovating a home, it’s important to understand the options when choosing the right access control.

Access using the key is the most common external door lock. Key input functions are often used with auxiliary locking tongues for added security. The inside of the single-cylinder fixing bolt has a thumb turn, and an entry key needs to be input from the outside. It is recommended to use double cylindrical fixing bolts for doors with glass panels and use keys on both sides of the door.

Another option for the outer door is the mortise lock or interconnect lock, which includes a unitary lock tongue that locks the key from the outside and inside of the house. Rotate the knob to pull out the retaining bolts and latch bolts for faster exit in an emergency.

Locks are an important part of the entire home security system. Let’s take a look at what types of common home locks are and how they work, so you can choose the most appropriate lock to protect your home.

Pin and pin lock mechanism

This conventional household external lock has a spring pin that is loaded into a series of small cylinders.

How it works: When the correct key is inserted into the lock, the spring compresses and lifts the pin. This will push the driver into the cylinder and unlock it.

Tubular lock

One of the most common types of interior locks for bedrooms, bathrooms, passageways and closets.

How it works: The tubular lock consists of a tumbler lock or an inside knob or button in the knob on the outside of the door.

Rim lock

These types of locks are usually mounted on the surface of the door, usually inside.

How it works: Unlock the door from the inside with a small latch. If used on the outside of the door, the rim lock typically has a smaller rim with a keyhole.

Mortise lock

The lock (very popular in Europe) has two different locking devices – the latch and the locking tongue. Unlike conventional door handle locks, the mortise lock is mounted in the lock pocket or in the tamper cut from the door. A board is also placed in the frame to which the door is attached.

Working principle: The mortise lock has a pin-shaped pin lock mechanism on the cylinder and the interior includes a single lever that is engaged by a flat-blade key. Since the mortise lock is installed in the actual door frame, it is very safe and prevents the lock from coming into contact.

mechanical lock

These popular home external locks require the use of a key.

How it works: A mechanical lock is prevented from moving by one of one or more metals (toggles, levers or latches) that fall into the slot of the bolt.

Electronic locks

This type of independent lock has an electronic control assembly that is mounted directly to the lock.

How it works: The electronic lock operates with current and can be accessed or opened with a personalized password or key.

Before choosing a door lock, you must be aware that this is only part of the family safety challenge. There are many locking options available, and you can protect your home and family life in the best possible way.
