Precise diagnosis · Explained quotation · Installation & adjustments

UNDERSTAND YOUR NEED
Three options, one explained.
Replace your keys
A compatible cylinder may be sufficient following a move or after losing your keys.
Repair the closure
A available component or adjustment can restore a mechanism that is still sound.
Strengthen the entrance
Assess the lock, cylinder protection, and door condition as a complete system.
LE BON DIAGNOSTIC
A solution tailored to your access requirements.
At Cran-Gevrier, a move-in, a lost key, or a forced closure may prompt considering a new lock. The first step is to distinguish between the need for new keys and a genuine mechanical failure. This distinction prevents unnecessarily replacing a functioning lock.
A sticking key may indicate a worn cylinder. A handle that is difficult to lift or bolts that rub may point to the lock case or misalignment. We check the lock, door movement and strikes before recommending adjustment, a targeted repair or replacement.
For a co-ownership property, indicate the presence of a common key at the hall and your door. If the request concerns a commercial or office space, specify access restrictions and the number of users to prepare an appropriate solution.
COMPATIBILITÉ & QUALITÉ DE POSE
Prepare for your intervention at Cran-Gevrier.
Indicate the address of intervention, whether the door is open or jammed, and whether you still have a working key. A general view of the door, an interior-side photo, and a photo of the frame help identify the equipment more accurately. Technical dimensions are confirmed before final supply.
The quotation takes into account the selected model, the cylinder if applicable, installation, and adaptations. A pre-opening may be required if the door is jammed; this is distinct from a replacement. The lead time depends notably on the availability of the part and is specified upon exchange.
For 24-hour locksmith assistance, contact us by phone to confirm availability and next steps. For a planned project, the form allows you to describe your needs. You can also discover our other interventions at Cran-Gevrier.
BEFORE WORK
What the quotation must specify.
The lock reference, supply, installation, adjustments, and any necessary adaptations are detailed according to your situation. If the door must be opened initially, this operation is noted separately. Also see our pricing details.
To facilitate the first replacement: a general view of the door, a photo of the internal mechanism, and photos of the markings on the edge. Avoid dismantling a lock that is still functioning.
YOUR QUESTIONS
Before replacing your lock.
Should the entire lock be replaced after losing keys?
Not always. If the mechanism is in good condition, replacing its cylinder may allow for new keying. The choice depends on the model and existing security features.
Are you working on a security door?
We can assess the replacement of its full-length covered multipoint lock or cylinder after identifying the doorset. All components and features of the complete system must be respected.
What is the cost of a lock change at Cran-Gevrier?
It varies according to the material, the condition of the door, and the required adaptations. A photo helps prepare the request, but the final quotation takes into account on-site inspections.
