Burglary and trespassing are just two of the many dangers lurking just outside your home. Any homeowner knows the importance of installing quality deadlocks to protect your home from such unfortunate scenarios.

A deadlock, also called deadbolt, can be installed in almost the same way as locksets. The best position for a deadbolt is about 200/300mm above the existing lockset or 200mm below it. This can vary and is dependent on the lockset height and security door hardware.

Use a Template

Use the template supplied to mark the hole locations. These are generally a 51 or 54mm hole through the face of the door (using a hole saw bit) and 22 or 25mm hole into the edge of the door and into the door frame (using a spade bit). Read more about deadlock installation Sydney.


Remember to drill all holes square and parallel to the door and when drilling through the face of the door don’t drill right through right through as this will tear the face of the door. Drill the holes as per the template. Hold the door with wedges when drilling into the edge of the door.

Fitting the Deadlock.

The lock bolt will need fitting into the door edge and its plate recessed flush. Mark the outline of the plate and scribe these lines. Use a sharp correct size chisel to cut out the depth required for the plate to sit flush on the door edge. Screw the bolt/plate into position. Install the lock body making sure it is the correct way up. Now the striker plate will need to be recessed into the door jamb. Mark this position using the centre of the latch onto the jamb, the striker plate must be in the correct position vertically on the jamb so the latch engages when the door is closed and doesn’t ‘rattle in the breeze’. Scribe the lines marked for the striker plate and chisel out so the plate finishes flush, mark the centre of the hole on the plate and drill out with the spade bit used previously. Screw the striker plate to the jamb. Test for correct operation.Read more about deadlock installation Sydney.

Important Tips

1. Buy “keyed alike” deadbolt and door knob lock sets for all external doors.

2. Purchase a high quality deadbolt from a hardware store.

3. Study the instructions carefully before the installation.

4. Get a professional’s help if you are not that confident with your carpentry skills.

5. Consider a lever style handle/deadbolt combination; levers can be easier to operate if your hands are full.

6. Check the height/location of the security door handle prior to fitting door hardware
