Types of Old Door Locks

Old door locks come in various designs and types. Each reflects the craftsmanship of the period it was made. Here are some commonly encountered types of old door locks:

• Mortise Locks

  This door lock is commonly found in deadbolts. The mortise lock fits into a pocket or cutout in the door edge. The pocket is created with high precision using a chisel. The lock case has a deadbolt and a latch. The bolt and latch slide into the door frame. The strike plate is mounted to hold the lock in place. A mortise lock can be a deadbolt, a latch or both. The lock must be installed in a mortise cut into the door. Therefore, it requires special tools. It is more secure because it is fitted inside the door instead of on the surface.

• Sash Locks

  These are surface-mounted locks. They are fitted on the surface of the door instead of inside a mortise cut. Sash locks are usually found in wood and some metal doors. They are used to secure doors where there is no mortise cut. The Sash lock fits into a mortise cut in the door frame. It has a deadbolt and a latch. A sash lock is usually less secure than a mortise lock. It is not as hard to pick or drill out.

• Deadbolts

  These are popular old door locks. They are still commonly used today. They fit into a metal cylinder. The cylinder is mounted in the door. The bolt slides into the frame to secure the door. There are three kinds of deadbolt locks. Single-cylinder has a key outside and a thumb turn inside. Double-cylinder has keys for the outside and inside. It requires a special shape key. Vertical cylinder deadbolts fit vertically in the door. They bolt doors shut and prevent them from being opened.

• Rim Locks

  These locks were popular in the 19th century. They are surface-mounted locks. Rim locks are installed on the surface of the door. They have a deadbolt that slides into the frame and a latch bolt. The latch bolt protrudes from the door to secure it. Rim locks are generally less secure than mortise locks. They are easier to pick or drill out. They were used in older wooden doors.

• Cabinet or Furniture Locks

  These locks are used in cabinets, drawers, and furniture. They are small and intricately designed. They come in different types and can be key locks or push locks.

• Keyless Locks

  These locks do not require a key to open. They are opened using codes, cards, or biometric data. They are popular in modern homes.

Function and Feature of Old Door Locks

These kinds of locks are not as advanced as modern ones but still provide a decent level of security. Here are some features of old door locks:

• Keyed Cylinder:

  Old locks often use a key cylinder to secure the door. This cylinder is a metal tube with small holes in it. Inside the tube are several metal pieces called keys that make the cylinder work. The cylinder has to turn freely to lock and unlock the door. Turning the key spins the cylinder and moves the bolt in and out of the door frame. If the key fits through one hole in the cylinder, the other holes allow the cylinder to turn freely. This basic design keeps the door secured with just one key fitting through the tube.

• Single Deadbolt:

  Some older locks only have one bolt that slides in and out to lock the door. This is called a deadbolt because it does not have a spring like the regular door bolt. The deadbolt lock turns the key to slide the thick steel bolt into the door frame. When locked, the door is secured in the closed position. Unlocking the deadbolt takes a little more time because it is more secure. One reason for this is that the deadbolt lock takes longer to unlock than a spring-loaded door bolt. Since the deadbolt does not spring back, it requires the key to turn and unlock the thick steel bolt. But this also makes the deadbolt more secure than regular door bolts.

• Knob Lock:

  Older knob locks are not as secure as deadbolts. They have a spring mechanism that can be wiggled open if there is no key. However, knob locks are still used today, especially in rooms that do not require as much security. The knobs on the door can be pushed to open the door more easily than a deadbolt. But knob locks alone are not enough to keep a door secure. Most knob locks also have a deadbolt that can be turned from the outside or inside using a key. The knob lock can help keep the door closed, but a deadbolt is needed for more security.
