For future reference, this information is publicly available on the (US) FCC website. If you have a key, look on the back and get the FCC ID listed there. Every device emitting radio frequency in the US has to have an FCC ID noted on the device. With the FCC ID you can go to
https://fcc.io and search the FCC website for the technical details of the device, including the radio frequency or frequencies the device operates on.
