Short stay key loss in Amsterdam is the steady accumulation of copies held by guests, cleaners and hosts, until nobody can say how many working keys exist for a single apartment.
Every short let ends with a key going somewhere. Posted back, left in a drawer, dropped in a letterbox, taken home by accident in a coat pocket. Multiply that across a season and the number of keys in circulation for one flat becomes genuinely unknown.
The problem with a key that never expires
A metal key cannot be switched off. Once it is out, it works until the cylinder changes, which is why short stay is the one use case where mechanical keys age badly. A guest from March is not a threat, but their key is still a working key in June.
Owners often notice this only after something goes missing, and by then it is impossible to say which key was used or whether one was used at all.
Access that expires by itself
A certified key safe with a code changed between guests keeps the key on site and under your control. An electronic cylinder goes further, giving each guest a code that stops working on their checkout date, and giving you a log of who opened the door and when.
Where the building has a shared street door with a mechanical key, that part usually stays as it is, so a hybrid arrangement is the norm. Both sides are covered on our locksmith services page.
Resetting an apartment that has been let for years
Start with one cylinder change to bring the count back to zero, then move to a system where access expires. Doing the second without the first leaves every historic key still valid on the door you did not change, which is the mistake we see most often.
Cleaning and turnover staff
In practice it is not usually the guests who accumulate keys, it is the people servicing the flat. Cleaners change companies, a laundry service subcontracts, a co-host stops working with you. Each transition leaves a key somewhere, and none of them feel significant enough to act on at the time. Reviewing who currently holds a physical key twice a year is enough to keep this from getting out of hand.
What guests actually experience
There is a practical argument as well as a security one. Guests arriving late from Schiphol with luggage do not want a key exchange in a bar around the corner, and hosts do not want to be woken by a message at one in the morning. A key safe or a code that works from their check-in time removes that entirely, which is why most owners who switch never go back.
Getting the paperwork right
Where the apartment is let commercially, your insurer and sometimes the VvE will have views about access arrangements. Ask before fitting anything to the facade, and keep the invoice showing what was installed and to what standard, because it is the kind of detail that only becomes important after an incident.

More answers sit on our locksmith FAQ page.
How often should a short stay cylinder be changed?
Mechanically, at least yearly. With expiring codes, only when the hardware needs it.
Are key safes allowed on the facade?
Check with the VvE, and in listed buildings check what may be fixed to the wall.
Can a guest code be time limited?
Yes, with an electronic cylinder.
What about the shared entrance?
That belongs to the building and usually stays mechanical.
Can you fit this between bookings?
Yes, including evenings and weekends.
