A sticking lock doesn’t always need replacing. In the 9th, where many doors are more than a century old, we start by adjusting and servicing, and only replace the cylinder or lock if it is worn. Price given before we come out, 24/7.
A lock almost always gives warning before it fails. If you recognise one of these signs, it is better to call us now than to wait for a broken key or a jammed door on a weekday evening.
A lock is adjusted on site: realigning the striking plate, resetting the hinges, cleaning and lubricating the cylinder with a suitable product, never ordinary oil, which clogs it up. If a part is worn, we show it to you before suggesting a replacement.
When the cylinder is too worn, we replace it with a high-security model of the same size; if it is the lock, we fit a model with the same dimensions so that the door does not have to be recut. The price is given before we start. Full replacement, lost keys, break-in: our lock change in Paris page covers each case.

In the 9th, the age of the building often tells us where the fault lies. Here is what we come across from one area to the next.
Moulded Restoration-era doors, often repainted several times: the paint ends up catching on the striking plate or the bolts. Clearing the painted areas and an adjustment give the lock back its smooth action.
19th-century apartment buildings built to let, narrow staircases, front doors that have moved with the building. A sticking lock here often comes from a door sagging on its hinges.
In offices, a lock wears out with the comings and goings: several dozen openings a day wear a cylinder out far faster than in a home. Regular servicing avoids a breakdown on a Monday morning.
Large doors in Haussmann-era buildings, often fitted with a multipoint lock installed several decades ago. These locks can be adjusted and serviced; when the original cylinder is no longer available, we fit a compatible one.
Door opening, door reinforcement, metal shutters: find our other services on the locksmith Paris 9 page.
Describe the movement where it sticks, or film it: that is often the key to the diagnosis.
Avoid cooking oil or ordinary penetrating oil: they trap dust and end up clogging the cylinder. A dry lubricant, graphite- or PTFE-based, works better. If the lock still resists, it is often the door that needs adjusting.
Yes, generally: you only pay for the call-out, with no parts to replace. We give you the price before we come, based on your description or a photo. If a part turns out to be worn, we show you before suggesting a replacement.
The wood of the door swells with damp and the cold thickens lubricants: the door rubs and the striking plate no longer lines up. An adjustment that allows for the seasons usually solves the problem.
When its pins are worn, when the key has play in it or when a key has been lost. A high-security Euro profile cylinder costs from €90 incl. VAT; a branded cylinder costs more.
