# Problems end of reservation

Why can't I end the reservation or lock the car?

There may be various reasons for this:

-   **Black chip on the car key has not been put back into the key box in the glove compartment**
    
-   The car is not connected to the charging station
    
-   The car has no reception --> Call support
    

> **Info:** Tip: If you have already inserted the black chip into the key box, pull it out again and reinsert it. If it still doesn't work, please contact support.

> **Info:** If you have any problems, you can contact our support on +43 5572 40 10 26 1
