How do I start my trip once I have a reservation?
Once you’ve reserved a vehicle, here’s how you start your trip:
1) In the Communauto mobile app, click “Start trip” in your current reservation.
- No smartphone? Tap your key fob (or equivalent) on the reader.
2) The doors will unlock and your trip will start.
3) Retrieve the car key from its holder in the glove box.
- Keep it with you during your trip and return it to its holder at the end.
You can also watch our short video about how it works.

Can my co-member access a vehicle reserved on my account (and vice versa)?
Yes and no…
Yes, for vehicles available by reservation, no for FLEX.
For FLEX, only the person who blocked the vehicle will be able to access it (unless you lend them your RFID key or equivalent).

It depends on how you plan to access the vehicle:
With an RFID key or equivalent: all members linked to the same family account can start a trip using their own RFID key or equivalent. In this case, you don’t need to do anything to share a reservation. It’s automatic! However, the same RFID key (or equivalent) that you use at the start of the trip needs to be used to end it.
With the app: for a reservation you made to be visible in a co-member’s account, you need to share it with them first. To do this:

Once a reservation has been shared, each member can access the vehicle and manage the reservation on their own account as if they had made the reservation themselves. Learn more.
