Key26S2 is 26 bit generic Wiegand keyfob. It is HID 1346 compatible. Made in Canada under HID license costs about 40% of original 1346LMMN keyfobs. You could pay more, but why?

It is ordered in boxes of 100. When ordering watch FC (Facility Code) if used. Also pay great attention to numbers since you don't want duplicates with what you already have in the system.
