Weak Lock Mechanisms
The most targeted vulnerability by burglars is inadequate locking systems. Standard single-point cylinder locks can be quickly opened using a crowbar or shimming technique. Research shows that 40% of burglars prefer this method.
Door Body Weakness: Thin Steel and Poor Welding
Many doors appear sturdy from the outside but are easily breached due to thin steel sheets (0.8 mm-1 mm) and insufficient weld points. Burglars can gain entry through these weak spots with a small drill or saw. A steel door with at least 1.5 mm thickness and fully welded edges should be preferred.
Hinges and Pivot Points
Even if hinges are mounted on the interior side, some models have external access. Hinges without rivets or locking pins instead of screws can be removed with a screwdriver. Additionally, the blind locking points on the hinge side are often neglected. A double-sided locking system and central internal lock eliminate this vulnerability.
At Işıldak Çelik Kapı, counter lock points and security pins are standard on all our models.
Door Handle and External Accessories
The exterior door handle can serve as a leverage point for burglars. Non-fixed or non-lockable handles can be broken with a crowbar to open the door. Also, some smart locks with weak encryption or open Bluetooth connections are vulnerable to cyber attacks. Systems with high mechanical security and stainless steel handles should be used.
Door Cylinder Security Vulnerability
Cylinder locks are more fragile than deadbolts and combination locks. Especially bump key or drill attacks can disable standard cylinders in seconds. Burglars frequently use this silent method. As a solution, high-security, drill-proof, and pick-resistant cylinders should be used.
- Security measure: Replace your door cylinder at least every 3 years or have it checked by an authorized technical service.
- Security measure: Cover all visible screw heads with decorative or welded plates.
- Security measure: Reduce leverage effect by leaving at least 10 cm distance between the door handle and the lock.
- Security measure: Use a double-sided locking system and side bolt on your steel door.
Conclusion and Recommendations
Door security is not limited to lock selection. Steel thickness, weld quality, hinges, and accessories must be evaluated holistically. At Işıldak Çelik Kapı, we offer proven solutions against these vulnerabilities in every door. We recommend having a security inspection done as soon as possible to protect your home.
