Hmmm, well OK.
The Schlage FE410F data sheet says
Credential: Supports smart and multi-technology aptiQ MIFARE classic or
aptiQ DESFire EV1
DT sell options for both of these
MIFARE classic
xM1
FlexM1 gen1
FlexM1 gen2a
FlexMT
DESFire EV1
FlexDF
but also likely to work
FlexDF2
xDF2
I still think we have a bit of work to do here to get this correct for you.
Of the above, Initially I would suggest you go down the Mifare path (because you can change the NUID numbers) however the DESFire are still viable.
If you can enroll them (home SHOULD be easy) Work you will need administrators on side.
If you can’t enroll, then of the Mifare, the FlexM1 gen2 would be my most reccomended, ONLY because you can use your phone to change the UID.
Otherwise you would need to buy a ProxMark3 and I don’t think you would have fun setting it up.
And you would likely only use it once
However, if we have a community member near Baltimore They maybe able to help you out.
@Satur9 springs to mind (Philidelphia) but my USA Georgraphy is not great.
@philidelphiaChickens may also be useful to try
@Satur9 is a very Knowledgeable and helpful member, plus for him having another “local” installer might be awesome for him.
HOWEVER
I still think we need to get to the bottom of you acess cards
