# Problems reservation start

Why can't I start the reservation?

If the car cannot be opened, there may be several reasons for this:

-   Reservation has not yet started -> car can only be opened from the start of the reservation
    
-   The wrong vehicle has been reserved (check license plate number)
    
-   caruso card/Klimaticket has not yet been activated
    
-   Payment authorization failed (check inbox)
    

If none of the above points apply, please contact caruso support.
