The Importance of Learning the Different Parts of a Door Lock

In Singapore, safety is a top concern for most households. We lock our gates, doors, and even bedroom doors to feel secure. Whether you install a digital lock, a deadbolt, or a simple knob lock, each of them has multiple working parts inside.

When any one of these fails, the entire lock can stop working, and that can cause anything from inconvenience to serious security risks. That’s why understanding a door lock parts layout is so useful. This is not only applicable to locksmiths but also to all homeowners and tenants who want peace of mind.

1. Keyhole / Keyway

This is the first thing you interact with when using a lock, where you insert your key. Inside the keyway are small pins or levers that read the cuts of your key. If the cuts match, the lock turns.

Most HDB flats in Singapore have conventional key locks, whereas condos and privately owned homes are moving towards electronic door locks. Still, even many smart locks have a backup keyhole. That’s why the keyway remains an essential part of a door lock.

Different Parts Of A Door Lock

2. Lock Cylinder

Behind the keyhole is the cylinder. This is the essence of the locking mechanism. It contains the wafers or pins which sync with the proper key. Cylinders are available in different styles:

In case your key fits into the lock but fails to turn freely, you may want to check the cylinder.

3. Deadbolt or Latch

That is the heavy-duty portion that fits into the door frame and locks your door. There are two main types:

  • Deadbolt: This needs manual or electronic movement to lock and unlock. Durable and suitable on front doors.
  • Latch bolt: Has a spring that lets it automatically retract when you turn the knob. Used for interior doors.

In most Singaporean homes, the main wooden door typically has a deadbolt, while bedroom doors often have latch bolts. Digital locks also use electronic deadbolts controlled by touchpads or apps.

4. Strike Plate

This is a metal plate fixed on the door frame. When the bolt slides into place, it locks inside the hole in the strike plate.

When your door wiggles or fails to remain closed, the strike plate may be out of position. In a hot, humid climate, such as in Singapore, a wooden frame may expand, causing the strike plate to shift in location each season.

5. Faceplate

The faceplate is the visible metal plate on the side of the door. It covers the latch or bolt and assists in maintaining the lock body in place. Faceplates are often ignored, but they hold everything steady. The entire mechanism may shift due to a loose or rusty faceplate.

6. Thumbturn

This is a small knob or lever on the inside part of the door. It allows you to lock or unlock the door without a key.

For example, many Singapore flats have a thumbturn for locking the main door from inside at night. It comes in handy when you need to lock without a key in case of emergencies.

7. Spindle

A spindle is a slim rod that interlinks both the handles on each side of the door via the latch system. By turning the handle, the spindle turns and moves the latch out of the way, allowing the door to open.

A damaged or broken spindle may result in a loose turning or failure of your handle to open the door.

8. Door Handles or Knobs

To open the door, you grab the handles and knobs.

  • In Singapore, more often lever handles are used, especially in new houses.
  • Knobs are more common in older properties and room doors.

There are also digital locks that have handles integrated with a fingerprint sensor or keypad.

9. Escutcheon Plate

This is an ornamental plate that goes around the keyhole or thumb turn. It also secures the keyhole against tampering. In Singapore, some models come with anti-drill or anti-pick to provide extra protection.

  • Place: The main door should have deadbolts, and the bedrooms should have latch bolts.

  • Usage: When you have elderly family members staying with you, then you should consider using locks that have big thumb turns or smart locks with fingerprint capability.
