A standard apartment door gives way in under three minutes to a crowbar. A certified security door resists for ten, fifteen, sometimes twenty minutes — long enough for almost every burglar to give up, since most abandon an entry after five minutes of resistance. AMG Serrurerie supplies and installs security doors and door armouring across all eight departments of the Paris region, from the first advice visit to the final adjustment.
Two approaches: new door block or armouring your existing door
The security door block replaces your door and frame entirely: a steel structure, a multipoint lock integrated at manufacture, hinge-side pins, and certified performance as a complete unit. It is the reference solution for main entrances, and the only one that carries a full A2P BP certification (BP1, BP2 or BP3 — roughly 5, 10 and 15 minutes of certified resistance).
Armouring keeps your existing door and reinforces it: a steel plate on the leaf, a reinforced frame, a certified multipoint lock, cylinder guard and hinge reinforcement. It is lighter on the budget, often preferred in co-owned buildings where the landing-side appearance must not change, and dramatically better than the original door — without reaching the level of a full certified block.
How the project runs
A visit first: we measure, check the frame and walls, and discuss what you protect and what your insurer requires — many French policies impose A2P-certified equipment above certain insured values. You receive a written quote with options. Installation takes half a day to a day; we finish with the adjustment, the demonstration, and the certification documents for your insurance file.

FAQ
Do I need my co-owners' approval? If the landing-side appearance changes, usually yes in France. Armouring that keeps the original panel visible often avoids the issue — we advise on the best route.
Do you also open and adjust existing security doors? Yes: see our security door opening and adjustment pages.
