1. Most common types of locks
There are several types of locks suited to your needs:

- Surface-mounted or mortise: depending on the door (fragile or sturdy). ([turn0search13])
- Connected: remotely controllable, integrable with home automation.
2. Security standards: the A2P certification
The A2P certification (Assurance Prévention Protection) issued by CNPP guarantees resistance to break-ins:
- A2P* : resistance ≥ 5 min
- A2P** : ≥ 10 min
- A2P*** : ≥ 15 min ([turn0search13])
Make sure all components (lock, cylinder, strike plate) are A2P approved so that your installation is truly secure. ([turn0search4])

7. FAQ
Can I change only the cylinder without touching the lock?
Yes, provided the cylinder is compatible (same height, same series) and ideally A2P.
Does my insurance require an A2P lock?
Often A2P *, or even multipoint. Check your contract, as this sometimes conditions compensation.
What should I do if I fall victim to a locksmith scam?
Keep the invoice and quote, contact the professional first, then appeal to the DGCCRF or a consumer association if necessary. ([turn0search3])
Are multipoint locks really effective?
Yes, especially if they are A2P. They reinforce the door’s cohesion, distribute pressure, and increase resistance to break-ins. ([turn0search13], [turn0search17])
