What is Rubik?

See how Rubik solves access to units:

How it Works

Discover how operators use Rubik's locks and app for easy, contactless access:


Secure The Unit

Rubik's app shows vacated and overdue units that need locking.

Your site manager locks them, then scans the QR code on the padlock with the app.

Rubik now remembers the unit, lock and unlock code for the next time you need it.


Send The Code

When a rental starts, your management software asks Rubik for the unlock code.

Then, it sends both the gate and unit access code to the tenant in one message.

This means tenants never use the app.


Return the Lock

Many operators prefer not to have access to rented units to avoid legal issues.

Before a move-in, they leave padlocks with keys in a unit, then sell it to the tenant.

Combination padlocks are returned to a drop box and later collected by your staff.

Are Rubik padlocks digital?

No. Rubik intentionally uses mechanical combination padlocks. Operators with smart lock experience prefer this simple solution.

Can my tenants keep the code padlock?

Most operators prefer to have their tenants return our locks. But yes, you can set that tenants keep the lock during their rental.

How many locks do I need?

As many as you have vacant & overlocked units at any time. If your tenants keep the locks, you'll need one per unit.

Do tenants use Rubik's app?

No, only your team uses the app to lock units. Your management system gets the unlock code from Rubik and sends it to your tenant.

Is Rubik a lot more work?

Are you checking units after a tenant moved out? This is when you use Rubik to secure the unit, too. It barely adds work.

Is Rubik unsafe compared to smart locks?

No. Rubik's locks secure vacant units or overlock occupied ones. Tenants typically use a padlock with keys – this determines their level of safety.

Can I log access and overlock instantly?

Most operators have an electronic gate access system that logs access and overlocks instantly.

So, what's the weakpoint?

For overlocks you have to go on site. Many operators don't mind: To them, it's enough when the gate access system overlocks instantly.

Do you support my management system?

We support Storeganise, Space Manager, Store365, StorApp for SiteLink, Stora and Kinnovis and are working on Storman.

Do you have an API?

Yes, Rubik has a well-documented API. Integrating takes 2 days at most. If you're interested, contact us at
