Direct compatibility answer
Will this credential work with your building?
Confirm receiver, RF coding and the exact proximity technology ordered for the property.
A matching model name does not guarantee a working credential. Secure systems can use different receiver generations, facility codes, card formats, encryption keys or pre-programmed number ranges inside visually identical housings.
