Keys lost on the metro, a stolen bag, a new apartment where you don't know who has copies, a lock that has been sticking for months: changing the cylinder or the lock is the safest way to be back in control of who can get in.
Price: from €160 incl. VAT. The exact price is given on the phone and confirmed in a written quote before any work. Day, evening and night prices
Cylinder only, or the whole lock?
In most situations, replacing the cylinder (the barrel the key goes into) is enough: it is quick and affordable. The whole lock is replaced when the case is damaged, after a break-in, or to upgrade to a stronger 3- or 5-point lock.
Understanding A2P stars
The French A2P certification, issued by the CNPP, rates resistance to break-ins: one star for 5 minutes, two for 10 minutes, three for 15 minutes. Some insurance policies require a minimum level: check yours and we will recommend the right model. High-security cylinders come with an ownership card that protects key copying.
Clear options, fitted prices
The locksmith shows you several ranges, from standard to certified high security, with an all-inclusive price (part and fitting). You choose, he installs it, then hands you the invoice, the new keys and the ownership card.

Frequently asked questions
How much does a cylinder replacement cost?
From €160 incl. VAT on weekdays (8am–6pm), €210 in the evening (6pm–10pm, and 8am–10pm on weekends and public holidays) and €230 at night (10pm–8am). A complete lock starts at €250. The final price depends on the brand and security level you choose: a detailed quote is given beforehand.
Should I change my lock after my keys are stolen?
Yes, especially if documents showing your address were taken at the same time. Depending on your policy, your insurer may cover the replacement.
Tenant or landlord: who pays?
Lost keys are usually the tenant's responsibility; replacing a worn-out lock is usually the landlord's. Your lease is the reference.
