Replace or Protect a Cylinder
The cylinder is the main security component of a lock and one of the first targets during a burglary attempt.
Depending on your existing installation, replacing the cylinder is not always necessary. Installing a cylinder protector or upgrading to a more resistant cylinder may be enough to significantly improve your security.
Before carrying out any work, we assess your installation to recommend the solution best suited to your door, your needs and your budget.
Reinforce Your Door
The weak points of a door are not limited to the lock. Depending on your door configuration, installing anti-pry angle bars, reinforced hinges or other reinforcement devices can significantly improve its resistance to forced entry.
We recommend only the reinforcements that are genuinely appropriate for your installation, without replacing components that are still in good condition.
Install a Multipoint Lock
A multipoint lock improves the resistance of a door by securing it at several locking points.
Depending on your door, we can replace your existing lock or install a suitable multipoint lock. We recommend the best balance between security, reliability and budget.
Upgrade to a Security Door
Not every door requires the same level of protection.
Depending on your installation, we can recommend several solutions, including pivot door reinforcement, steel door cladding or the traditional Paris-style door reinforcement. After assessing your door and frame, we will recommend the solution that best matches your security requirements and your budget.
Install A2P-Certified Security Equipment
A2P certification identifies security products that have successfully passed recognised burglary resistance tests.
We assess your installation and recommend A2P-certified equipment whenever it offers a genuine benefit, taking into account your needs, your budget and any requirements from your insurance provider.
