How can customers return a vehicle after hours?

Using the Enterprise key drop box is the correct method for customers to return a vehicle after hours. This system is designed to facilitate easy vehicle returns when the rental location is closed. It allows customers to securely drop off the keys and return the vehicle without needing to interact with staff. The key drop box is typically located at the rental facility, ensuring that the vehicle is accounted for once it is returned.

The other options do not align with established procedures for after-hours vehicle returns. Calling customer service does not facilitate a return at that moment, as it involves speaking with an agent rather than completing the return process. Leaving the keys in the glove compartment poses security risks, as it could lead to lost keys or unauthorized access to the vehicle. Returning to a different location is not allowed, as vehicles must be returned to the designated rental location specified in the rental agreement.
