Firefly 318ald31k keychain remote
The firefly 318 keychain remote is an Allstar 9931T compatible remote in compact form. It operates on the 318mhz frequency and uses 9 dip switches that have three position settings. The dip switches go up, middle, or down thus making it a trinary or three position remote. The allstar 9931T is a visor size remote, so if you want a keychain version this is it.
