During the opening hours of our Bookbinder Rent-a-Car branches, our employees personally accept the rental car upon return. If your planned deadline is outside of our opening hours, this is also possible. The key return runs in this case through the night safe. In some locations (airports) the return is handled by the employees of a service provider. If these are already in the evening, you have the option of using the key box on site or handing over the key at the Buchbinder counter.
