Why choose additional locks?

An additional lock makes your door harder to force. It works differently than your main lock, which means burglars need two different techniques. Modern additional locks also have core pull protection and a security cylinder.

You can mount an additional lock at any height. Many people choose a lock at knee height or just above the main lock. This makes it even more difficult for burglars. From € 75,00 you can have an SKG-certified additional lock including installation.

Professional installation of additional locks

An additional lock must be mounted exactly right. Our fitters first determine the best position on your door. They check the construction of your door and frame. Then they drill the holes for the lock and the striker plate exactly to size. This way your lock works smoothly and safely.

Suitable doors for additional locks

Front doors

An additional lock is perfect for front doors. It strengthens your existing security. We mount the lock in a strategic place where burglars have difficulty reaching it.

Back doors

Back doors are often vulnerable. An additional lock makes them immediately more secure. The lock also works well on plastic and aluminum doors.

Office doors

For companies we often install additional locks with special cylinders. These can be incorporated into a central lock.

Recognize a worn out additional lock

Problems with the key

A good additional lock works smoothly with the key. Do you notice that the key is turning harder and harder or is regularly stuck? This often indicates wear in the cylinder lock. Also, if the key no longer goes smoothly in the lock, this is a sign that the lock needs to be replaced.

Sounds when closing

An additional lock should work almost silently. Grinding or creaking sounds are a warning. This usually means that the moving parts in the lock are worn. A rattling sound when turning the key also indicates that the lock is no longer working optimally.

Lock not working properly

The lock should lock firmly and immediately. If this no longer happens, it could be because:

  • Worn parts in the lock
  • Misalignment with the striker plate
  • Damage to the lock mechanism
  • Sagging of the door

Visible problems

Check your lock regularly for:

  • Play in the housing
  • Loose parts
  • Rust formation
  • Damage to the exterior
