What can happen in short-term rentals
Every year, landlords lose part of their income and precious time because of old locks
2~8 hours
Spent handing over keys every week
You spend a lot of time just organizing check-ins and meeting with residents
Lack of control tools
Without a digital event log, it is impossible to know who was in the apartment and when
Remote object management
Handing over keys becomes a logistical challenge, often requiring an intermediary
Risk of key copying
A duplicate physical key can be made in 5 minutes, resulting in the need to change the lock cylinders after guests leave
Emergency response
If a guest loses their key or locks themselves out of the apartment, you have to go there in person or call a locksmith
I’m sorry, I lost the keys to your apartment...
I’ll be right there to give you the spare ones
Why physical keys remain a weak point
NK Pro turns access from manual routine into a controlled digital process — with fewer trips, risks, and expenses.
Without NK Pro
A physical key creates constant operating costs
Access cannot be transferred remotely
No control over cleaners and staff
Costs and complications when keys are lost or stolen
Risk of duplicate keys and no notifications about entry or break-ins
With NK Pro
One lock changes the entire rental workflow
Save on physical keys and lock cylinder replacements
Resolve emergency situations faster
Fewer trips and less staff workload
More returning guests and referrals
Less manual work — more control over properties and the guest experience.

Dismantle the old lock
Remove the handles and trims, unscrew and remove the cylinder and the old lock body from the door leaf.
step 2
Mark the lock mounting area
Place the template against the door edge and face. Mark the hole centers and the outlines of the recesses for the lock and strike plate.
step 3
Prepare the holes
For wood, use a screwdriver and chisel; for metal, use a rotary tool and burrs. Follow the markings carefully.
step 4
Install the mechanical lock components
Secure the new lock body in the door edge. Install the cylinder, handles, and trims. Screw the strike plate onto the door.
step 5
Prepare space for the electronic units
Using the template, mark and drill the holes for mounting the external and internal units.
step 6
Secure the electronic units
Mount the housings using the fasteners from the lock kit. Route and connect the wires between the units.

How it works
Install the smart lock
Install the lock on your door using the detailed instructions and templates. For Moscow and Moscow Region, you can order installation by our specialists.
The lock fits most standard doors, and small differences in size are covered by a decorative cover. See the image:
Connect the app
Download the app and activate the lock in a couple of minutes. From that moment on, you will have access to all access management tools, analytics, and facility control.
Grant access
Create guest keys with restrictions based on dates, roles, and schedules. To check in, guests will need to send a link or passcode.
Watch the check-in
Upon arrival, guests can open the door using NFC in the app or a passcode. No meetings, key transfers, or waiting — just quick and remote access.
Keep track of events
You retain control over your space during your guests’ stay. The built-in event log shows who opened the lock and when.
Trust automation
After the end of the term of residence, the digital key immediately stops working. You do not need to revoke anything manually — the system will do everything itself.

Notes:
- According to a study by ABI Research commissioned by the NFC Forum (an industry standards body), consumers in nine countries rated contactless NFC payments as the safest, most convenient, and most reliable payment method compared with plastic cards, QR codes, and cash. This finding was published in the report “NFC Contactless Payments: A Global Consumer Perspective” (2023).
