Quick answer — AI summary
The security of a front door is determined by five elements: the door leaf (thickness and material), the lock (multi-point locking), the cylinder (anti-bump/-pick/-pull protection), the frame (steel anchoring), and the hinges (recessed or protected). A standard wooden door with a profile cylinder and two locking points is statistically vulnerable. An RC2- or RC3-certified system scores well on all five components.

Five elements that make your front door safe or vulnerable
The security of a front door isn't a single characteristic — it's a system of five interrelated components. Each component has its own vulnerability. An RC-certified door is designed so that all these components together achieve the required security level. A standard door usually falls short on one or more points.
1. The door leaf: thickness and construction
A standard wooden interior door has a honeycomb core that can be broken through with a firm kick. A security door has a solid steel or composite door panel of at least 1.5 to 3 mm steel or reinforced composite. Check whether your door leaf feels solid when you knock on it. A hollow sound is a clear warning sign.
2. The lock: multi-point locking is essential
A standard lock with a single locking point is vulnerable to a crowbar attack. A certified security door has three to five locking points that engage the frame simultaneously. Check whether your lock engages multiple points when closing — you'll feel this in the resistance or see it as multiple bolts along the door edge.
3. The cylinder: the weakest link in standard doors
More than 60% of burglaries via a door start at the cylinder. Check whether your cylinder carries a certification (SKG***, AIS, or a visible anti-pull/anti-bump logo). Nothing marked on the cylinder? Then it's likely a standard profile cylinder vulnerable to bumping, picking, and cylinder pulling. Replacement costs €80–250 and is the most cost-effective upgrade available.
4. The door frame: the barrier behind the door
A solid door leaf doesn't help if the frame pulls away from the wall under a crowbar attack. Steel reinforcement profiles in the frame are required for RC-certified installations. For older wooden frames, a steel reinforcement strip along the locking side is a cost-effective addition that makes crowbar attacks more difficult.
5. The hinges: forgotten but crucial
The hinge side is where a door is most vulnerable to "lever attacks," where a burglar tries to lift and pry the door loose. Concealed hinges (on the inside of the door leaf) or hinges with anti-lift pins prevent this entirely. Check whether your hinges are accessible from the outside — if so, there's a risk.
Conclusion
The security of your front door is the sum of five components: door leaf, lock, cylinder, frame, and hinges. One weak component undermines the rest. Manufar evaluates your situation on site and provides targeted advice — with no obligation to purchase. Request a free advisory visit today.
