Ermétis stands out for its burglary resistance: four locking points fitted with 22 mm rotating chrome-plated side bolts that resist sawing. It also has a cylinder guard with an anti-drill insert, which adds to its security. The lock is certified burglar-resistant, with an A2P* rating.
Security goes hand in hand with strict key control. Ermétis comes with four patented Picard VTX keys, sealed in secure packaging, together with a numbered ownership card. Keys can only be copied on presentation of the numbers shown on the key and on the card.
Ermétis is also easy to live with. A noise damper and Delrin rings that guide the bolts make it run quietly, and it locks with a single turn of the key.
This versatile lock can go from four to six locking points by adding two 18 mm top and bottom points. These points have reinforcing brackets that resist being torn out or forced in. Ermétis is available in a three-metre height and in a Tapkey version, so your phone can be used as a key.
To suit different set-ups, the cylinder length can be adjusted with the Picard VTX options. The standard cylinder measures 46.5 mm and can be extended in 5 mm steps as needed.

Frequently asked questions about high-security locks
Another question? Call us, even at night.
What does A2P certification mean for a lock?
A2P is the certification awarded by CNPP to security locks after break-in tests. The stars show the resistance time: 5 minutes for one star, 10 minutes for two, 15 minutes for three. Your insurer may require a minimum level.
How many locking points should I choose?
A 3-point lock locks the door at the top, bottom and side: it is the recommended minimum for a front door. A 5- or 7-point lock spreads the load over the whole height and resists prising better, especially on a tall or exposed door.
Surface-mounted or mortice lock: what is the difference?
A surface-mounted lock is fixed to the inside face of the door: it fits most flat doors and can lock at several points. A mortice lock is set into the thickness of the door: more discreet, it needs a fairly thick door.
Can the keys of a high-security lock be copied?
Yes, but only on presentation of the card of ownership: patented keys are reproduced by the manufacturer or an approved dealer. You can also order your keys by number from us.
How is a lock fitted?
We first check your door, then give you the price of the lock fitted. Fitting is done by appointment, in a single visit; we hand over the keys and the card of ownership. Our fitting is guaranteed for 5 years.
