Further, a method is provided for cleaning an outer element of a vehicle, in particular at least one optical element of a rear view device of a motor vehicle by detecting a contamination state including a predetermined degree of contamination or a predetermined type of contamination of the outer element, emitting at least one signal that is characteristic for the detected degree of contamination including an input signal for a key device, and transmitting an optically, acoustically, or haptically detectable output signal by the key device, with a request for cleaning using the at least one cleaning means of the key device or which is connectable with the key device. ## Claims ### Claim 1 A key device for at least one of opening and starting a vehicle, comprising: a main body; at least one cleaning means which is in or on the main body for cleaning an optical element of a rear view device of the vehicle; a receiving unit for receiving at least one wirelessly transmitted input signal emitted from the vehicle which provides information about a degree of contamination of the optical element; and a transmitting unit for transmitting at least one output signal which provides information about a degree of contamination of the optical element. ### Claim 2 (depends on 1) The key device according to claim 1, wherein the transmitting unit comprises at least one of a lamp, a loudspeaker, and a vibrating unit for vibrating the main body. ### Claim 3 (depends on 1) The key device according to claim 1, wherein a fluid application unit is at least partially hidden in the main body in a basic state, and is configured to be moved out of the main body at least partially, depending on an input signal, into an operating state. ### Claim 4 (depends on 1) The key device according to claim 1, wherein a fill level of the container with a cleaning fluid is configured to be determined, or a fill request is configured to be transmitted, depending on at least one of a specific fill level and a transmitting unit. ### Claim 5 (depends on 1) The key device according to claim 1, wherein the cleaning means comprises at least one mechanical means for the mechanical rubbing off of dirt comprising at least one of a cloth, a brush, and a wiper lip. ### Claim 6 (depends on 5) The key device according to claim 5, wherein the mechanical means is hidden at least in sections in the main body in a basic state and can be moved out of the main body at least partially, depending on an input signal, into an operating state. ### Claim 7 (depends on 5) The key device according to claim 5, wherein an abrasion of the mechanical means is configured to be determined, or a signal relating to the abrasion of the mechanical means is configured to be transmitted, in a form of a request for replacement via a transmitting unit. ### Claim 8 (depends on 5) The key device according to claim 5, wherein at least one of at least a part of the cleaning means is movable into an operating state, and at least a part of the cleaning means is transferable back into a basic state from the operating state. ### Claim 9 (depends on 1) The key device according to claim 1, wherein at least a part of the cleaning means is at least one of detachable from the main body and affixable onto the main body. ### Claim 10 (depends on 1) The key device according to claim 1, further comprising at least one of: at least one key that is insertable into a lock; at least one mechanical actuation means for effecting at least one of an opening and closing of the vehicle by means of wireless transmitted signals; a detection means for automatic recognition of a pre-determined vehicle and for effecting the opening of the pre-determined vehicle; a digital key comprising a smartphone with a digital key function; and an automatic signal transmission unit for detecting the key device by a pre-determined vehicle. ### Claim 11 (depends on 1) A method for cleaning an outer element of a vehicle comprising at least one optical element of a rear view device of a motor vehicle, with the following steps: detecting a contamination state comprising at least one of a pre-determined degree of contamination and a pre-determined type of contamination of the outer element; emitting at least one signal that is characteristic for the detected degree of contamination, comprising an input signal for a key device according to claim 1; and transmitting an optically, acoustically or haptically detectable output signal using the key device with a request for cleaning using the at least one cleaning means of the key device or which is connectable with the key device. ### Claim 12 A key device for at least one of opening and starting a vehicle, comprising: a main body; at least one cleaning means which is in or on the main body for cleaning an optical element of a rear view device of the vehicle; a receiving unit for receiving at least one wirelessly transmitted input signal emitted from the vehicle which provides information about a degree of contamination of the optical element; and a transmitting unit for transmitting at least one output signal which provides information about a degree of contamination of the optical element, wherein the cleaning means comprises at least one mechanical means for the mechanical rubbing off of dirt comprising at least one of a cloth, a brush, and a wiper lip, and wherein at least one of at least a part of the cleaning means is movable into an operating state, and at least a part of the cleaning means is transferable back into a basic state from the operating state.
