Things you’ll need

  • Mortise lock
  • Cylinder rim lock kit

The steps to follow

  1. To prevent your home from being burgled, it’s best to fit strong locks and bolts to doors
  2. You can also fit a strong lock that can be bolted from the inside
  3. You’ll need to fit locks and bolts on your back and side doors
  4. Mortise and cylinder trim locks are the best option for your home
  5. Cylinder trim locks automatically lock as the door closes. It can only be opened from the inside or with a key
  6. Mortise locks are sturdy and cannot be tampered with easily. They are best used on back and side doors. Remember to make sure that the mortise lock used on an exterior door conforms to safety and quality regulation BS 3621. This will ensure that the lock is sturdy enough to resist drilling or forcing
  7. Install a strike plate and an additional steel plate on the back side of the door jambs. This will prevent the jambs from splintering when forced
  8. If your door has a window pane in it, it’s easier for burglars to break the glass and unlock the door from the inside. To prevent this from happening, install a deadbolt that can only be opened with a key. Due to fire safety, these types of locks are not normally installed on your primary door
  9. Hang hinges on the inside of the doors
  10. If you install a spy hole, this will allow you to see who is on the other side of the door before you let them in
  11. Another recommended security measure is to install a safety chain below the door lock so you can see who is at the door without opening the door completely when someone calls
