Tip 1 for securing the front door – the mortise lock
We can secure the front door with the mortise lock. It’s possible because a mortise lock is one of the most commonly used solutions for front door burglary protection: A cylinder bolt is pushed into a designated opening in the door frame by locking and unlocking the lock. This type of lock is invisible and difficult to manipulate because the lock is built into the door.
There are several variants of this – for the most diverse needs, for example, fire protection doors, narrow door profiles, or a self-locking model with an anti-panic function. With the latter, the locked door can also be opened from the inside without a key.

Tip 3 for Securing the Front Door – (The Digital Door Viewer)
The equivalent of the intercom system for the front door is the door viewer for the apartment door. It is available as a classic version or as a digital version with a screen display. The advantage of the digital variant is that you cannot see from the outside whether someone is looking through the door viewer from the inside.
A classic or digital door viewer has the advantage of being able to check when the door is closed whether the person in front of the door is known, looks trustworthy, and how many people are in front of the front door. As a result, you don’t have to face the other person personally and you have the closed door as protection between you and the person(s) in front of the door. Trick thefts or apartment robberies can be thwarted with a little caution.

Tip 11 for Secure the Front Door- The door bar lock

Doors in old buildings pose a major risk when it comes to door security: Moldings and other decorative elements often prohibit the installation of additional security devices.
A door bar lock, on the other hand, is also suitable for high doors of up to almost three meters, which are often found in old buildings. When locked, the lock snaps in at the top and bottom, locking the entire height of the apartment door.Table could not be displayed.
If you want to make life difficult for burglars, you can increase your door security, e.g by the following measures:
- Replace the existing locking cylinder with a door cylinder with a security card
- Attach a protective fitting
- Mount a protective rosette
Tip: Placing a visible camera in the entrance area can also deter burglars. However, only one’s property may be monitored at a time. In addition, any fellow tenants walking through the picture must be informed about this and have agreed to the recording of the picture.
For optimal burglary protection, both the police and insurance companies recommend reinforcing doors with additional security against breaking open or levering open. After all, the most obvious entry point for burglars is the house or apartment door.
If a door is additionally secured against burglary using hinge side protection, additional locks, and suitable wall anchors, opportunistic thieves usually give up after a short time so as not to be caught trying to pry open it. Just as additional door security measures act as a deterrent for burglars, unsecured doors can be easily recognized by protruding locking cylinders or protective fittings that can be unscrewed from the outside
Extra tip: To secure the front door well, a door leaf that is too weak should also be checked and, if necessary, retrofitted. Because experts generally recommend using a solid wood door that is at least 40 millimeters thick.
