Key safe for car dealerships and garages: flexible key handover around the clock
With a smart key safe, your customers can drop off or pick up their vehicle keys at any time. This allows you to extend your service times without having to adjust your opening hours. Vehicle handover can take place flexibly, even outside regular business hours.
Your customers save time and benefit from a convenient service. For you as a company, this means optimised workshop planning and better capacity utilisation - right from the start of work.
Handover of keys for rental vehicles
A digital key safe with API connection enables automated vehicle handover and is therefore ideal for weekends and night-time hours. Keys and documents remain safe in the locker. Customers book online, receive a code and remove the key at the terminal. The handover protocol is saved automatically.
Returns can also be seamlessly integrated, enabling an all-round digital and secure rental process.
