Use these keys from Schneider Electric to manually operate your selector switch. They're compatible with devices from the brand's Harmony XB4 and Harmony XB5 series. Each pack contains two keys, which are useful to have on hand as a backup, in case you lose your main key. A black plastic head gives you a secure grip on the key when you insert it into the slot and turn it to open or activate your device.
