The car keys are only needed to start and turn off the engine and should stay inside the Zipcar at all times. You should always use your Zipcard or mobile app to lock and unlock doors.
If the vehicle has a push start button, you can just put your foot on the brake and push the button to start the vehicle. If your vehicle has a traditional ignition, the keys will be in the center console or tethered to the steering wheel column.
If you cannot find the keys anywhere inside of the vehicle, give us a call for further assistance at 1-866-4ZIPCAR.
