Digital keys for rental businesses are changing the way vehicle access works. The global car rental market is valued at over $103 billion in 2025 and is expected to reach $191 billion by 2035. Within that market, two very different customer segments are growing at the same time. Short-term rentals currently dominate, holding around 73.9% of market share. Long-term rentals are also expanding quickly, growing at over 7.4% per year as more businesses and individuals seek flexible alternatives to vehicle ownership. Both models come with their own access challenges. MoboKey’s platform is built to handle both, from a single device and a single app.

The Different Demands of Short-Term and Long-Term Rentals

Short-term and long-term rentals look very different from an operations standpoint. Short-term rentals move fast. Bookings can last a few hours or a few days. Customers expect quick pickup and drop-off. Any friction in the handover process leads to a poor experience and a bad review.

Long-term rentals move at a different pace. Renters may hold a vehicle for weeks or months. The priority shifts from speed of access to reliability, ongoing control, and flexibility. Operators need the ability to update permissions, extend agreements, and manage access remotely without requiring any in-person interaction.

In both cases, physical keys create unnecessary complications. For short-term operators, key handovers add time and staff costs. For long-term operators, physical keys are a security risk over an extended period. A key can be copied, lost, or shared without the owner’s knowledge. Digital access control solves both problems cleanly.

How Digital Keys for Rental Work in Short-Term Bookings

For short-term operators, speed and simplicity are everything. MoboKey makes both possible. Once a MoboKey Pro device is installed in the vehicle, the operator shares a digital key directly to the renter’s smartphone. The key activates at the start of the booking window and expires automatically when it ends.

The renter receives a notification, opens the MoboKey app, and walks to the car. There is no counter, no staff interaction, and no waiting. They unlock the car, drive, and return it. When the rental ends, access is removed instantly. The next renter’s key can be issued moments later.

This kind of seamless handover is exactly what today’s rental customer expects. Additionally, operators on platforms like Turo and Getaround benefit directly. They can host more bookings without being physically present for each one. The entire access flow runs automatically, around the clock.

Why Long-Term Rentals Benefit Just as Much

Long-term rental customers have different needs, but digital keys for rental serve them just as well. A renter holding a vehicle for a month does not need to carry a physical key everywhere. They access the car through their phone throughout the entire rental period.

For the operator, the advantages are even more significant. With a physical key, you have very little control once the vehicle leaves your possession. You cannot easily verify where the car is, and you cannot revoke access without arranging an in-person meeting. With MoboKey, you retain full remote control for the duration of the agreement.

If a long-term renter misses a payment, you can restrict access directly from the platform. If the agreement is extended, you simply update the access window remotely. There is no need to issue a new key or meet the renter in person. Furthermore, the vehicle’s location is always visible through the app. You always know where your asset is.

One Platform for Both Rental Models

One of the most practical advantages of MoboKey is that digital keys for rental work across both models from a single platform. You do not need a separate system for short-term bookings and another for long-term agreements. The same device, the same app, and the same dashboard manage everything.

This matters especially for operators who run a mixed fleet. Some vehicles may be listed on hourly booking platforms while others are under monthly corporate agreements. MoboKey manages each vehicle independently with its own access settings, time windows, and permissions. You switch between them without switching systems.

For businesses ready to build their own branded rental platform, MoboKey Go provides a complete white-label solution. You launch your own app with full digital key functionality built in. This lets you serve both short-term and long-term customers under your own brand, without building the underlying technology yourself.

The cost model stays consistent across both use cases. MoboKey runs on a one-time hardware cost per vehicle with no annual fees and no commissions. Whether you are managing a single car or a growing fleet, your costs remain predictable and your margins stay protected.

According to Global Market Insights, the online segment of the car rental market already accounts for over 75% of all activity. Operators who offer a fully digital experience are the ones winning in this market. MoboKey puts that capability within reach for any rental business, at any scale.
