Because it is easier to choose the right solution when you understand how it works.
Understanding Your Home Security
At Serrurier Vert, we believe that informed customers make better decisions. We explain how locks work, how burglars typically attack doors and which upgrades genuinely improve security.
Main Components
Euro Cylinder
The component that receives the key. High-security cylinders provide improved protection against drilling, snapping, pulling and lock picking.
Lock Body
The mechanism installed inside (mortise lock) or on the surface (rim lock) of the door.
Multipoint Locks
Lock the door at several points simultaneously. Their effectiveness also depends on the door, frame and installation quality.
Security Hardware
Security escutcheons, reinforced handles, anti-pry protection and hinge reinforcement increase resistance against forced entry.
Door Reinforcement
Many existing doors can be reinforced without replacing them. Paris-style reinforcement is commonly used on traditional apartment doors.
Armoured Door Sets
Replace the complete door assembly and provide the highest level of protection.
Opening Techniques
Whenever possible we use non-destructive methods such as the slip-card technique. Drilling is used only when necessary. Modern cylinders are designed to resist lock picking.
Standards & Certification
A2P certification is the main French security certification recognised by many insurers.
Insurance
French home insurance policies sometimes require specific security equipment. We take these requirements into account before recommending upgrades.
