Aloha!
I am working on rekeying an administration building and came across a unique question. We are going Best B SFIC away from an LSDA LSA keyway. The current "lock" on the restroom is a LSA C500 with no pins at all. This way anyone with any key that works in that building can use it to unlock the door. I want to maintain this when I move to SFIC, but obviously that's more of a challenge with the control key. I can work on cross keying the door but I might still have the same problem as the cross key will include at least 30 change keys. Is it possible to make a SFIC to allow any key in that keyway or should I just look into issuing out a restroom key?
Thanks ahead of time....
