There may be a problem, but you can open it remotely.

Okay, but how would they type these electronic keys if you don't want a keyboard? Can you brighten this up for me?

For example, by sending a text message to a lock with a (temporary) code. Ev. by logging in to a temporary user created by me to the lock panel via a browser. I don't know, I'm thinking so loud. I don't want to burden people with installing anything. I know from experience that not everyone wants to do it, not everyone can

Maybe SIM-STER 5 or BRAM STER 3 by Megaelektronik? You give the customer the phone number to which he rings. The controller then activates the bolt for a second. You can turn this function on and off via SMS at any time. BRAM STER has a programmable list of three allowed numbers that it responds to.

Hello,

'In a minute' I will need some smart solution when it comes to opening and closing doors. To be precise, it is a door lock in an apartment rented for days. I don't smile to run around with keys every day, so I'm looking for something intelligent, i.e. a lock where I could generate electronic 'keys' for landlords. I do not want a lock with a classic keyboard on the outside of the door (renovated tenement house and I would not like to stand out with a door handle in the corridor).

Maybe you use something like that and recommend something?

I was looking at Gerdalock V3, but the opener must have an application installed there, which is a slight inconvenience.

The budget is around the price of the above-mentioned Gerdy. Up to PLN 1,500.

Best regards.

I have searched the depths of the internet and there is no 100% satisfactory option for me when it comes to an electronic lock.
And I think I have to make a slight compromise.

Maybe someone will tell you - a code lock (keyboard in the signboard outline - see photo) with the possibility of generating codes for a specified period of time, so that they can be sent to the customer by text message / e-mail.

Here, the management of the application on the net (Polish product, but the lock is visually too coarse):

EDIT:
I am looking for something like this, unfortunately only available in the USA for now:

Get interested in the Selkod company from Krakow: http://www.selkod.com.pl/63,NOWOSCI.htm - they have all the functionality you need, the system is made on Aperio handles.

Topic summary

✨ The discussion revolves around finding a smart door lock solution for short-term apartment rentals, specifically looking for a system that allows the generation of electronic keys without the need for a physical keypad. The GerdaLock V3 was initially considered, but concerns were raised about the requirement for an app installation. Participants suggested alternatives such as GSM intercoms and locks that can be controlled via SMS or phone calls. Various models were mentioned, including "SIM-STER 5" and "BRAM STER 3" by Megaelektronik, which allow temporary access through programmable phone numbers. The conversation also touched on the need for a wireless solution that does not require extensive installation, with some users expressing interest in products from Selkod and Eura tech. Ultimately, the user is seeking a balance between functionality and ease of use, with a budget of up to PLN 1,500.

FAQ

TL;DR: For short‑term rentals, set a smart lock workflow around a PLN 1,500 budget; "I'm looking for something intelligent"—avoid guest app installs by using SMS/call‑to‑open GSM controllers. [Elektroda, mEjdej, post #16809195]

Why it matters: Hosts want hands‑off check‑in without corridor‑facing hardware or guest app friction.

Quick Facts

Budget target: up to PLN 1,500 for the lock solution. [Elektroda, mEjdej, post #16809195]
No exterior keypad preferred to keep the corridor look consistent. [Elektroda, mEjdej, post #16809195]
GerdaLock V3 works but requires the opener to install an app. [Elektroda, mEjdej, post #16809195]
GSM controllers can trigger the latch by SMS/call; some whitelist up to 3 numbers. [Elektroda, Szyszkownik Kilkujadek, post #16811202]
Electric strike needs door wiring and buffer PSU; single‑point holding lowers burglary resistance. [Elektroda, suworow, post #16809409]

Who is this FAQ for and what problem does it solve?

Hosts of daily/short‑term rentals who want smart access without handing over keys, exterior keypads, or guest app installs. It summarizes workable GSM, code, and cloud options discussed by practitioners, centered on ~PLN 1,500 budgets and minimal corridor changes. [Elektroda, mEjdej, post #16809195]

Can I avoid making guests install an app?

Yes. Use SMS or a simple call‑to‑open approach. Create temporary access by assigning a phone number or time‑limited code handled by the lock’s controller. The request was to keep guests app‑free by using SMS or a browser login. [Elektroda, mEjdej, post #16811157]

How do GSM intercom/modules unlock the door?

A GSM controller answers a call or receives an SMS and energizes the strike for about a second. You can enable or disable this function via SMS and even keep a small whitelist. One cited unit stores up to three allowed numbers. [Elektroda, Szyszkownik Kilkujadek, post #16811202]

What’s the simplest guest flow without apps?

“SMS or just calling the indicated number is the easiest/best.” Share the number for the door’s GSM controller for the stay period, then revoke after checkout. This keeps guests app‑free while you stay in control. [Elektroda, suworow, post #16811174]

Can I generate time‑limited codes without mounting a big keypad outside?

Cloud‑managed code locks exist, but the thread’s OP avoided bulky corridor hardware. A Polish option (RentingLock) offered online management, and a compact US product (Gate) was noted. Both reflect time‑bound code workflows. [Elektroda, mEjdej, post #16841097]

Does GerdaLock V3 fit guest self‑check‑in needs?

It can, but guests must install the app to open the door. That extra step caused friction for the OP’s daily‑rental use case, pushing them toward SMS/call solutions instead. [Elektroda, mEjdej, post #16809195]

What wiring and security trade‑offs come with electric strikes?

You must run cables through the door or frame and add a buffer power supply. A strike holds the door at one point, which lowers resistance to forced entry. Consider this if your building has stricter security expectations. [Elektroda, suworow, post #16809409]

How many numbers can some call‑to‑open units allow?

A referenced controller (BRAM STER) supports a programmable list of three authorized numbers. That’s enough for host, cleaner, and current guest, then you rotate after checkout. [Elektroda, Szyszkownik Kilkujadek, post #16811202]

Which locally mentioned products support rental workflows?

RentingLock provides online code management for rentals, though one host felt the exterior piece looked too bulky for their corridor. It still shows the direction: cloud codes and remote management. [Elektroda, mEjdej, post #16841097]

Any integrators using Aperio handles for apartments?

Yes. Selkod (Kraków) was recommended for solutions made on Aperio handles. These handles integrate with access control while keeping the door’s exterior clean. [Elektroda, rzjasio, post #16866911]

Who mentioned the Wano vG-BL1 remote lock?

A contributor suggested the Wano Solutions vG‑BL1 as a remote lock for apartments, and the OP confirmed contact with the vendor. It’s aligned with rental use cases. [Elektroda, agra, post #16866205]

Is there a compact, camera‑style US option to watch?

Yes, the Gate smart lock was cited as a desirable, compact solution, but it was available only in the USA at the time. It combined remote management and guest access. [Elektroda, mEjdej, post #16841097]

How do I set up a simple call‑to‑open GSM controller?

Insert SIM and program the whitelist or enable call‑to‑open.
Wire the controller output to the electric strike/bolt.
Test by calling the controller; it should pulse the latch for ~1 second. “First one I found” models were linked as examples. [Elektroda, karl102, post #16810824]

Can I just unlock remotely for a guest on arrival?

Yes. You can open the door remotely using the controller, which suits guests who call you at check‑in. This avoids sharing permanent codes or keys entirely. [Elektroda, Szyszkownik Kilkujadek, post #16809406]

Did the original poster report a final choice?

A follow‑up asked the OP which solution they chose, seeking a retrospective. No final selection was posted in the thread at that time. [Elektroda, Szyszkownik Kilkujadek, post #18511273]

What do these terms mean: GSM module, electric strike, Aperio?

GSM module: a cellular controller that unlocks by SMS/call. Electric strike: a frame‑mounted latch released electrically. Aperio: access‑control door handles used by integrators in managed systems. [Elektroda, rzjasio, post #16866911]
