In Paris, burglaries are unfortunately frequent, especially in residential buildings. However, most break-ins could be avoided with simple actions and appropriate equipment. As a locksmith in Paris, we regularly encounter situations where security mistakes make the burglars' job easier. Here are the 7 most common mistakes to avoid to effectively protect your apartment.
1) Not locking your door with a double turn
One of the most widespread mistakes is to leave your door simply closed. Burglars often test by pressing at the top or bottom of the door to check if a lock point is engaged. If the door is not locked with a double turn, it can be opened in a few seconds.
👉 To reduce risks, develop the habit of always locking with a double turn and favor a multipoint lock that secures the top, bottom, and side of the door.
2) Having a European cylinder protruding outside
A protruding cylinder is extremely vulnerable: it can be torn off or drilled in an instant. This security mistake is still common in many Parisian apartments.
👉 The solution is to install a high-security cylinder with anti-tear and anti-drill protection, flush with the door. These devices significantly complicate the burglars' task.
3) Hiding a key in the mailbox or under the doormat
Many think they secure their home by leaving a spare key in the mailbox or under the doormat. In reality, mailboxes are not secure: most burglars have universal passes to access them. This mistake is responsible for many burglaries in Paris.
👉 Entrust your duplicates only to a trusted person and avoid any hiding place immediately near your door.
4) Not installing an A2P certified lock
A basic lock can be picked or broken quickly. Experienced burglars can recognize a fragile lock in a few seconds.
👉 Installing an A2P certified lock (1, 2, or 3 stars depending on the resistance level) with anti-drill protection is a real guarantee. This certification is recognized by insurers and strengthens the security of your apartment.

5) Neglecting the installation of a reinforced door
In Paris, where burglaries often target the front door, not considering the installation of a reinforced door is a mistake. A standard door, even equipped with a good lock, remains fragile.
👉 The installation of a reinforced door or door reinforcement reduces the risk of break-in to almost zero. It is an investment that combines security, insulation, and added value to your home.
6) Neglecting lighting and alarm systems
An apartment without automatic lighting or an alarm system is an ideal target. Burglars favor dark and poorly protected places.
👉 Install motion detectors, a connected alarm system, or visible surveillance cameras. These deterrent devices greatly reduce burglary attempts.
7) Not calling a professional locksmith
Installing a low-end lock yourself or neglecting the advice of a specialist is a common mistake. A poorly done installation can leave significant security gaps.
Conclusion
By avoiding these 7 security mistakes, you significantly reduce the risk of burglary in Paris. Properly locking your door, installing a certified lock, considering the installation of a reinforced door, and calling a professional are essential steps to effectively protect your apartment.
