Cleaning with smart lock: secure access without handing over keys
In a cleaning with a smart lock, the team enters your home with a code or digital key that only works during the agreed time window. You receive a notification when they enter and another when they leave. No keys under the mat, no scheduled meetings at the door, and no one keeps a forgotten copy in their pocket. When set up correctly, this system is safer and more convenient than handing over a physical key. If poorly configured, with a unique code that never expires, it is just an invisible key that no one controls. This guide explains how to set up the right system, step by step, for a home in Lisbon, a holiday home, or an apartment between tenants.
In summary
- Create a unique code for the cleaning company, never the same as the one used by family or guests, and limit it to the days and hours of the visit.
- Activate entry and exit notifications on your mobile: they are your confirmation that the visit took place and how long it lasted.
- The entry log identifies individuals, so it is treated as personal data under GDPR: use it for security, not for surveillance.
- In old buildings in Lisbon, the street door is often the real problem: resolve it before buying the lock.
- Technology only solves half the issue. The other half is knowing who enters: a fixed, selected team with a clear checklist.

How a cleaning with a smart lock works
A smart lock replaces or complements the door cylinder and opens via code on a keypad, through a mobile app, by card, or by fingerprint, depending on the model. For those hiring cleaning, what matters is the ability to share temporary access and view the history of openings.
In practice, a visit goes as follows:
- The day before, the team's code is active only for the agreed day and time window, for example from 9:00 AM to 1:00 PM.
- Upon arrival, the professional opens the door with the code. You receive a notification on your mobile with the entry time.
- During the cleaning, the door can remain locked from the inside, as on any normal day.
- Upon exit, the lock automatically locks (if that function is active) and you receive a new notification.
- After the time window, the code stops working. If someone tries to use it at 10:00 PM, the door does not open.
Manufacturers catering to the local accommodation market in Portugal highlight this use as one of the core functions: Yale, for example, emphasizes the ability to adjust temporary access for cleaning or maintenance teams between bookings. Tedee describes the same logic for residences and offices, with codes valid only during the defined period and real-time alerts.
Which lock to choose for receiving a cleaning team
Not all smart locks are equally suitable for this purpose. The decisive question is simple: can the professional enter without installing your app and without relying on your mobile? If the answer is no, each visit depends on you.
| Type of solution | How the team enters | Advantage for cleanings | Weak point |
|---|---|---|---|
| Numeric keypad lock | PIN code | Does not require the professional's app or mobile | Needs batteries; codes must be changed |
| Motor over the cylinder + external keypad | Code on the keypad, or app | Keeps the physical key as an alternative; installs without renovations | Without a keypad, requires sharing invites in the app |
| Lock only by app (Bluetooth) | Digital invite in the app | Detailed history by person | The professional must install the app and have battery and network |
| Lock with Wi-Fi connection or bridge | Code or app, with remote management | Can create, change, and delete codes remotely | Extra cost of the bridge; depends on home internet |
For a home where cleaning is weekly or biweekly, the most practical combination is usually a motor over the cylinder, an external keypad, and a Wi-Fi bridge. This way, you can create and revoke codes from anywhere, and the team only needs to know the numbers.
As for prices, there are entry-level models that already cover the essentials. A Portuguese security retailer lists the Nuki Smart Lock Go at €149.00, with installation inside the door in less than five minutes and without drilling. Always check if the keypad and bridge are included or sold separately, as this is where the budget usually increases.
The street door, the problem no one anticipates
In Lisbon, many apartments are in buildings with a common key door, without any electronic system. You may have the most sophisticated lock on your floor, but the team could still be stuck outside. Before purchasing anything, consider the building's entrance:
- Intercom with remote opening: if the building has one, you can open the door remotely when the team arrives.
- Key safe with code: keeps the street door key in a dedicated safe. It works, but the code must be changed regularly.
- Common door key given to the company: acceptable if the company has a clear key management policy, identified by code and never by address.
Any alteration to the common door, even a safe fixed to the wall, should be discussed beforehand with the condominium administration.
Setting up access step by step
This is the procedure we recommend for those hiring us with a smart lock. It takes about 15 minutes the first time and then works automatically.
- Create a user or code just for cleaning. Give it a recognizable name, like "Cleaning," to identify it in the history.
- Set the recurring schedule. If cleaning is every Tuesday from 9:00 AM to 12:00 PM, configure the code for that day and add a 30-minute buffer on each side for traffic and unforeseen events.
- Activate entry and exit notifications for that user. It’s the simplest way to confirm the visit without having to ask.
- Activate automatic locking, if the model allows it, so the door never remains just ajar.
- Test the code with the team on the first visit, preferably with someone at home. Configuration errors are discovered here, not on a Saturday morning with the house empty.
- Agree on a plan B. What happens if the batteries run out or the internet fails? Most models have a physical key or emergency power: decide where that alternative is kept and who knows about it.
- Review access every three months. Delete codes of those no longer providing service: former employees, technicians, guests, visiting family.
One code per person, or one per company
The most common mistake is creating a single code shared by everyone entering the house. Experts in access control recommend the opposite: unique codes per professional or per company, so you can revoke access without affecting all others. If the cleaning company changes staff, or if the contract ends, you delete one code and the household continues as before.
The same guide highlights an advantage that many owners only discover later: when the cleaning team finds a malfunction, they can grant a unique access to a plumber or electrician in a few minutes, without having to travel.
Mistakes that leave the door open
The smart lock increases control, but only if used judiciously. These are the slips we see most frequently:
- Permanent codes. A code without an end date is like a copied key. Each code should have a validity window.
- Obvious codes. 1234, the children's birth date, or the door number are the first to be tried.
- Sharing by message without context. Never send the code and address in the same message to an unknown number. Use the company's official channel.
- Forgotten batteries. Most apps warn when the battery is low. Ignoring that warning is the most banal cause of a failed visit.
- Notifications turned off. Without them, you lose the main advantage of the system: knowing, in real-time, who entered.
- Trusting technology instead of trusting people. A well-configured code says nothing about who uses it. The question remains who the professional is, who selected them, and who is accountable if something goes wrong.
Privacy and GDPR: what the entry log implies
The history of a smart lock shows who entered, at what time, and for how long. When that log identifies an individual, such as the cleaning professional, it becomes personal data and falls under GDPR.
In practice, for an individual hiring cleaning, this translates into three precautions:
- Purpose: the log serves for the security of the house and belongings, not to monitor the attendance of those working there minute by minute.
- Transparency: the team should know that entries are logged. Clearly stating this at the start of the service avoids misunderstandings.
- Proportionality and security: keep only the history you need and protect the app account with a strong password and two-factor authentication.
The National Data Protection Commission has insisted, in its oversight activities, on the need for robust authentication and differentiated access control to the collected data. If, in addition to the lock, you have cameras inside the house, the issue becomes more serious: before recording someone working inside your home, consult the CNPD or a lawyer about what is permitted, as the rules for video surveillance are stricter than for a simple entry log.
Holiday homes, secondary residences, and tenant changes
It is outside the weekly routine that the smart lock shows its full value. Three typical situations:
The holiday home that remains closed for months. The owner lives abroad or in another city and wants to find the house ready when they arrive. With the lock, the team enters the week before, airs it out, cleans, checks for humidity and leaks, and you see the entry and exit on your mobile, wherever you are. This is the type of service we provide in residence care.
The tenant change. Between the departure of one and the arrival of another, there are only a few days and several people needing access: cleaning, painter, boiler technician. One code for each, with a short validity, avoids the key rush. For this tight window, we have move-in and move-out cleaning.
Short-term accommodation. Here the lock becomes essential infrastructure. Those managing holiday properties in other markets reach the same conclusion: a comprehensive vacation rental management combines guest access, cleaning, and maintenance in the same flow, so nothing depends on physical keys. The logic is the same in a well-managed long-term rental: complete rental management is only smooth when you always know who has access to the property and why. Access control platforms also describe how smart locks streamline cleaning rotations in vacation rentals, especially when codes are generated from bookings.
Our perspective
We work every day in homes in Lisbon where no one is present during cleaning. Therefore, our opinion is practical: the smart lock is an excellent tool, but it is not what makes it safe to let someone enter your home. What makes it safe is knowing exactly who enters.
That’s why we don’t send random third parties. Our professionals are selected and trained by us, and whenever possible, it’s the same team that returns to your home. A fixed team knows the house, knows where the products are, how the door keypad works, and that the living room window should not be left open. When the code only serves that team, during that time window, the lock's history tells a simple and verifiable story.
Access management is part of our service from the first contact: we agree with you on how the team enters, what the plan B is if something fails, and how the street door key is stored. At the end of each visit, you receive a digital report, and the checklist we follow is the same one you can consult. If a problem arises, we resolve it quickly and in your language, as we provide support in several languages, which is very important for those managing a home in Lisbon from abroad.
The advice we give to those who ask us is this: choose the company you trust first and only then the lock. Good technology with the wrong people is still a risk. The right people with a well-configured code are the combination that gives you back time without taking away your peace of mind.

Frequently asked questions
Is it safe to give a door code to the cleaning company?
Yes, as long as the code is exclusive to the company, has limited validity to the days and hours of the visit, and notifications are active. This way, you always know when the team entered and exited, and you can delete access in a second. The decisive factor remains the company: selected professionals, a fixed team, and someone who is accountable if something goes wrong.
What happens if the lock runs out of battery or internet?
Most models warn in advance when the batteries are low and maintain an alternative, such as a physical key or emergency power. Without internet, the codes already saved on the keypad usually continue to work, but you can no longer change them remotely. Agree with the cleaning company, before the first visit, what the plan B is.
Do I need to be home for the first cleaning?
It is not mandatory, but we recommend it. On the first visit, the code is tested, the house is shown, priorities are agreed upon, and it is clarified where the products are and what should not be touched. From then on, the team works alone with the agreed checklist.
Can I check the team's entry history?
Yes, and it is one of the advantages of the system. Just remember that this record is personal data: use it for the security of the house, inform the team that it exists, and do not keep it longer than necessary.
Does cleaning with a smart lock cost more?
Access via smart lock is not a separate service: it is how the team enters. The price depends on the type of cleaning, the house, and the extras you choose. Ask us for a proposal for your home, and we will include access management in the conversation.
