Layer 01
Software
One admin area for operations and support cases – and a booking page your guests understand right away.
Your partner for self-service rental
Self-service rental from one source
Your rental. Open, even when nobody is on site.
Sunlock brings together booking software, smart locks and the right way to secure your rental object – built from real experience in rental operations.
The problem
Rental businesses need flexibility – not a permanently staffed counter.
01Staff are expensive and hard to find.
02Guests expect long, flexible opening hours.
03Small sites barely pay off under classic operation.
04Guests expect intuitive, digital steps.
Sunlock can support your team or run the entire handover with minimal staff or none at all.
The system
The self-service operating system
Software, access and securing work as one – grown out of hands-on experience.
Layer 02
Smart locks
Time-limited access through PINs that only work for the booked period.
Layer 03
Securing & station
The physical link between lock and rental object: mounts, cabinets, stations.
And if the right setup does not exist yet, we build it with you.

„We wanted out of a franchise contract without giving up the rental. We have been working with Sunlock for two seasons now: the rental runs steadily and pays off better than before.“
„One season in, barely a single support request. We handle maintenance and service – Sunlock handles the renting.“
