How to choose a high-security lock for your Paris apartment

In Paris, apartment security is a serious concern — especially in high-density arrondissements. Choosing the right high-security lock can make all the difference.

What is an A2P certified lock?

A2P (Assurance Prévention Protection) is the French certification system for lock security. Locks are rated A2P* (15-minute resistance), A2P** (20 minutes), and A2P*** (30 minutes). Most insurers in France recommend at least A2P* for apartment coverage.

Which lock is right for your Paris apartment?

For standard apartments above ground floor, an A2P* cylinder with anti-drill and anti-pick protection is sufficient. Ground-floor or high-risk locations should consider A2P** or a 3-point lock system. Premium brands include Mul-T-Lock, Fichet, Vachette, and Bricard.

How much does a high-security lock cost in Paris?

A2P* locks start at €100 installed. A2P** and above typically range from €200 to €400, including labour and parts.

FAQ

Does my insurance require a specific lock type?
Many French home insurers require at minimum an A2P* certified lock to cover burglary claims. Check your policy before purchasing.

What is the difference between A2P and A2P**?**
A2P*** locks resist picking, drilling, and forced entry for at least 30 minutes — significantly harder to bypass than A2P* (15 minutes).

Can I upgrade my existing lock to high security?
In most cases yes — a locksmith can replace your existing cylinder with a high-security model without changing the entire lock body.
