One key for several doors
When several cylinders are ordered together on the same combination, one key opens them all: these are known as “keyed-alike” cylinders. The entrance, the office and the stockroom can then all be locked with a single key.
For this, the locks must take cylinders of the same type, which is the case for most locks with a Euro profile or round cylinder. For a team, you can go further: each person opens only the doors that concern them, and a master key opens them all. We look at how the premises are organised before placing the order. For a flat or another type of door, see our lock change in Paris page.
To prepare the order
- Count the doors: entrance, offices, stockroom, cellar, bike store.
- Photograph each lock: with the door open, from the front and from the side.
- List the people: who needs to open which doors, and how many keys to allow for.

One key for several doors: your questions
One set of premises, several doors, several brands? Describe the situation to us and we’ll suggest a solution.
My locks are different brands: is it still possible?
Often, yes, if they take cylinders of the same format: it is the cylinder that carries the combination, not the lock. When a lock does not accept that format, we suggest replacing it, or keeping a separate key for that door.
What is a master key system?
It is the way the keys for a single site are organised: each key opens a set of doors defined in advance, and a master key can open them all. For an office of a few people, keyed-alike cylinders are often enough.
What budget should I allow for new cylinders?
A high-security Euro profile cylinder starts at €90 incl. VAT. For several keyed-alike cylinders, the price depends on the model and the number of keys: we give you a quote before ordering.
If an employee loses their key, does everything have to be changed?
With keyed-alike cylinders, the lost key opens every door in the set: so the whole set has to be changed, or at least the cylinders on sensitive doors. With a master key system, only the doors that key opens are affected. It is something to plan for when you order.
