The Passport Key™ works with the Passport™ Intelligent Cat Flap and the Passport Intelligent Dog Door and can be used for an additional pet using the Passport or as a replacement if your pet’s Passport Key is lost.

Worn on your pet's collar, the Passport Key uses radio-frequency identification (RFID) technology by using a unique code to signal the Passport to operate as programmed for your pet.

The Passport Key is about the size of a quarter and does not require batteries to operate. Each Passport can program up to 20 Passport Keys.
