Dormakaba 12640-P27-BK – Frequently Asked Questions

1) Will a Dormakaba 12640-P27-BK fob work on my Saflok guest room locks?
The 12640-P27-BK MIFARE Plus key fob is built for supported dormakaba, Saflok, and Ilco 79 Series RFID lock systems. It reads at 13.56 MHz under ISO/IEC 14443A, which is the contactless standard those RFID locks use. If your property is running the older mag-stripe or proximity 125 kHz Saflok hardware, this fob won't read on it, you need the RFID lock generation.
2) Is the 12640-P27-BK the same as the older 12640-P24-BK fob we've been buying?
It's the replacement for it. The 12640-P27-BK supersedes legacy part number 12640-P24-BK, so if your purchase records still show the P24, the P27 is what you order now. It's a 2K MIFARE Plus credential with a 7-byte UID.
3) What's the difference between a 1K and a 2K MIFARE fob for hotel locks?
Memory. The 12640-P27-BK carries 2K of EEPROM read/write memory, versus 1K on the smaller credential. That extra space is what holds the additional data a lock system writes to the credential, room assignments, access groups, and audit data written back at the door. If your dormakaba or Saflok system was commissioned expecting 2K credentials, a 1K fob will not hold the full data set.
4) Do I need an encoder to use these fobs, or do they work out of the box?
A blank credential. The 12640-P27-BK ships as a 2K MIFARE Plus fob with a 7-byte UID and no room or user data on it, your dormakaba, Saflok, or Ilco 79 Series front desk or property management software writes the access rights to it. The fob is the credential, not the programming.
5) Will a Dormakaba 12640-P27-BK fob open a non-Dormakaba MIFARE reader in the same building?
Not something to assume. The 12640-P27-BK is specified for supported dormakaba, Saflok, and Ilco 79 Series RFID lock systems. It's ISO/IEC 14443A at 13.56 MHz, so a third-party reader on that standard can see the 7-byte UID, but whether your other system accepts that credential depends on how that system is configured, not on the fob. For mixed-vendor buildings, verify the credential format with whoever commissioned the other reader.
6) Can I order Dormakaba MIFARE fobs in a color other than black for staff versus residents?
The 12640-P27-BK is a flat black fob only, there's no second color on this part number. Properties that want to separate staff from residents at a glance usually do it with a colored key ring or a printed tag on the ring hole rather than the fob body.
7) Should I buy fobs or cards for apartment residents on a Saflok system?
Both are the same credential technology, the difference is how it carries. The 12640-P27-BK fob has an integrated key ring hole, so it rides on the resident's existing keys and is harder to lose than a card in a wallet. A card is what you want when you need a printed surface, photo ID, room number, or property branding. For resident and employee credentials where nothing has to be printed on the face, the fob is the simpler item to stock.
