When you rent out a flat you are not standing in, the mechanism is trivial. What decides whether the evening goes well is who can prove they belong there, who is allowed to authorise spending, and how many keys are still unaccounted for by Sunday.
A locksmith will not open a flat because a stranger says they rented it. Give the name on the booking, your own number and a line saying you authorise entry, and the conversation on the doorstep takes one minute instead of twenty.
Name a figure you are happy to approve on the spot. Under it, the work goes ahead; over it, you get a call. That single sentence removes an entire evening of messages across a time zone.
A guest flies home with the set in a coat pocket roughly as often as a key safe jams. Both end the same way: somebody has to get in tonight, and the cylinder probably wants changing this week.
Each line below removes one round of messages. Together they are the difference between one visit and three.
You approve and you pay. Nothing else lands on you.
Address, access, limits and invoice details. Keep the message — you will reuse it every time.
For a guest standing outside at eleven, proximity beats everything else on the list.
Price and arrival window come to you before anything is touched.
Opening tonight and changing the cylinder tomorrow is usually the cheaper and calmer order of events.
One honest caveat for anyone managing several units. This is a matching service that connects you with independent locksmiths. It is not a maintenance contract, there is no service-level agreement behind it, and no guaranteed response time exists — not at night and not in August. If you run a dozen apartments and need a name that always answers, what you actually want is a locksmith on retainer, and you will be told that here rather than sold something else.
Opening a door is reported at €70–150 and replacing a lock at €60–250. Typical range according to public listings and price pages — indication, not a quote. Sources: an OLX locksmith listing for Algés, the published Bricovitor call-out reference, Zaask's lock-replacement guide and Fixando's page for fitting locks and safes, all read in August 2026.
Short-term rentals cluster in the historic centre, where the street door is often two hundred years old, the stairwell is unlit and the flat door was fitted in 1974. Longer lets spread much wider, and the Cascais line carries the properties where the hardware is worth the most.

One message with the full address including floor and door, the guest's name and number, a line saying you authorise entry, and a photo of the lock taken by the guest. That is everything needed to start, and it takes about ninety seconds to write.
Yes — give the company name and NIF with the request rather than afterwards. Reissuing a Portuguese factura later is possible but slow, and some independents will simply not do it.
Yes, and it is a common one. Usually it is opened and the contents recovered, then the box is replaced because a jammed one tends to jam again. Mention the make and where it is mounted if you know.
Get the flat opened for the changeover, then change the cylinder rather than waiting for a set to arrive by post. A key in a suitcase somewhere in Europe with your address attached is not a set you should count on.
No. This site matches requests with locksmiths and nothing beyond that. Key holding, cleaning and guest communication stay with you or your property manager.
Assume so and plan for it. The city fills up, everybody's schedule tightens, and the research behind this site could not verify seasonality either way — so the honest advice is that a spare set with a neighbour is worth more in August than any promise anybody can make you.
Do it properly a single time and every future problem starts halfway solved. WhatsApp is easiest across time zones.
Send the address, who is standing there and your spending limit. The rest is handled without you.
