Your benefits

Reduce Costs

Reduce handover and documentation costs. Vehicle data such as mileage and fuel level are sent from the vehicle directly to your rental management software, saving you time and money. Contactless pick-up and drop-off are now possible and accurate.

A Better Experience

Manage the entire booking process from reservation to return documentation within your existing rental management suite, easily and digitally. Customers can skip the line, to receive digital keys and be on their way faster, and easier. Because it's contactless, we can help get you to a 24/7 operation.

Improved Control

Thanks to automated data processing, you can always keep track of the vehicle location and status. You have full control over the validity of the digital vehicle keys and can issue or revoke authorizations around the clock.

Improve security

Time-bound, digital access authorizations minimize the risk of theft, misuse or loss. The digital keys are transmitted in encrypted form and expire at the end of the use period. With liberkee®, you can modernize your rental fleet and increase security at the same time.

Reduce Errors

Fully digitized processes eliminates the need for manual handovers and written documentation. Telematics data flows directly to your rental management software for accurate and transparent record keeping to minimize costs, and maximize utilization.

Create Synergies

The liberkee® retrofit system is equally suitable for high-traffic and counterless car rentals. Thanks to the liberkee® app, the system can also be expanded to include additional digital authorizations and integrate them into existing access solutions. This allows you to create end-to-end solutions for different applications, such as contactless trailer rental.

Installed in minutes

Our retrofit module includes all components required for installation and safe operation. The module can be installed in virtually all makes and models within a few minutes and replaced just as quickly. Original keys remain intact and can continue to be used alternatively or in parallel. Since no vehicle components are affected, you can flexibly expand the fleet, replace vehicles or convert the system to different vehicle generations.

Frequently Asked Questions

How does Liberkee work and how do I install the system?

The heart of the system is the Liberkee retrofit module. This module carries the original vehicle key and performs all vehicle functions such as open/close and engine start/stop. The retrofit module is connected to the vehicle's OBD II interface and is also supplied with power from there. Using an integrated SIM card, the retrofit module connects to our cloud-based key management software via the local mobile network. Once the reservation process is complete, our server transfers the authorization in encrypted form to the vehicle user's smartphone. The smartphone then authenticates itself when approaching the vehicle and the user can perform the actions authorized for him. At the end of the booked usage time, the vehicle driver can lock the vehicle via smartphone before the digital key (the digital authorization) automatically expires.

Can I install the retrofit module in any vehicle model?

Generally speaking, Liberkee supports all modern makes and models. Please ask our customer service for an up-to-date list of supported vehicles. If you have a specific model in mind, reach out to our customer service.

Do I need special knowledge or tools for the installation?

The retrofit module is supplied with easy-to-understand installation instructions. Depending on the vehicle model, you will need standard tools such as a screwdriver or pliers for installation.
