Will my co-member be able to access my reservations as well?
Yes. Your co-member will be able to unlock your reservations with their key fob (or compatible RFID card) and vice-versa. However, note that the same key fob (or compatible RFID card) that was used to start a trip must be used to end the trip.
In Alberta and Nova Scotia, your co-member will also be able to unlock your round-trip reservations through their account on the mobile app. The same account must be used to complete the trip.
Please note for FLEX trips that only the member who blocked the car will be able to unlock it. (See « Will my co-member be able to access a FLEX vehicle blocked using my account?« ).
