I own a short term rental that has an Assa Abloy Essence lock that I am not allowed to change. These locks are not networked. Mifare 1k Classic
The HOA is telling us they can now offer us FOBs that can be programmed to timeout after the renters stay is up. Ex - Renter stay is 5 days, FOB will disable itself in 5 days so FOB can be thrown out or if lost will not allow access after stay duration as they all do now.
Of course they want a monthly fee for this service.
Is this possible to program on the NFC, since the lock is not networked?
Can I do it myself and avoid the monthly fee they are offering.
I have the Proxmark3 Easy and can duplicate my FOBs now.
