Compatibility decision rules
Match each verdict to the evidence available
Compatibility depends on the exact model, part identity, market and official compatibility wording—not appearance.
Exact model explicitly listed
The official part record names the full model.
Series-level support only
The family is supported, but the exact model is not named.
Missing listing or market mismatch
No direct evidence means compatibility is not inferred.
Officially excluded
Used only when an official record explicitly says it is unsupported.
Microchip matrix
Medium door + cat + supported chip type is the only captured implanted-microchip path. PetSafe does not document implanted-chip use for dogs or the Large door in these records.
- FDX-B: 15 digit
- FDX-A: 10 digit
- AVID H
- AVID Encrypted: 9 or 15 digit
Pet Door Key matrix
Use the key that matches the door size. PetSafe directs dogs and unsupported microchip cases to a Pet Door Key, and each product package includes one matching-size key.
FAQ
SmartDoor Connected Pet Door frequently asked questions
Each answer stays within the facts and sources shown on this page.
01Which microchips work with the PetSafe SmartDoor Connected?
For cats using the Medium door, PetSafe lists FDX-B 15-digit, FDX-A 10-digit, AVID H and AVID Encrypted 9- or 15-digit microchips.
02Can the Large SmartDoor use my pet's implanted microchip?
The captured PetSafe records limit microchip pairing to cats using the Medium SmartDoor. Use the matching Pet Door Key for the Large door.
03When should I use a Pet Door Key instead of a microchip?
PetSafe recommends microchip use for cats on the Medium door. Use a matching-size Pet Door Key for dogs, the Large door, or cats whose microchip is unsupported or unavailable.
