PetSafe Passport Key
The Passport Key™ works with the Passport™ Pet Access Smart System™ 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.
