The PetSafe Large Electronic Pet Door uses a collar-activated entry with an auto-locking system to ensure only your pets enter. It supports multiple programmed keys for up to five pets and runs on four D-cell batteries. Installation works in wood, metal, PVC, or paneled doors 1 1/2″ to 2″ thick, with a wall kit available for added flexibility.

PetSafe Electronic Pet Door — Small (Rust-Proof, Collar-Activated)
Small PetSafe models offer the same collar-activated entry and auto-locking features in a compact unit designed for pets up to 15 lb. Like the larger version, installation is DIY-friendly for wood, metal, PVC, or paneled doors, with optional wall installation for added flexibility. This option is ideal for small dogs or cats in apartments or homes lacking exterior walls suitable for a door insert.
Aiday Automatic Dog Door (Medium, Collar Sensors)
Placed for medium-sized dogs up to 40 lb, this Aiday model uses two sensor collars so only your pet can enter or exit. It auto-opens when approached and locks eight seconds after exit. The sensing range can be adjusted to two configurations, making it suitable for shy or energetic pets. It supports custom scheduling and manual override, and the frame is premium aluminum with an expandable tunnel to accommodate wall thickness. Installation is straightforward, requiring a 9.2″ x 14.6″ opening.
Automatic Sliding Glass Dog Door — Large (Collar Sensor)
This large sliding glass door from Aiday is designed for sliding glass doors and fits openings around 10″ wide with an adjustable frame for height from 76″ to 80-11/16″. It includes two exclusive sensor collars and auto-opens as your dog approaches, then locks eight seconds later. A one-button control adjusts the sensing range. The door is engineered to prevent entry by strays and is ideal for homes with large dogs and glass patio doors.
Power PET Automatic WiFi Door — Large (App-Controlled)
High Tech Pet’s Power PET door is app-controlled and operated by an ultrasonic pet collar. It emphasizes secure, 24/7 entry and exit with an auto dead bolt lock for airtight security. The fully automatic system runs on its own power with a safety retract mechanism if the door encounters an obstruction. This model is suited for tech-forward households seeking remote monitoring and control for larger pets.
SmartDoor Never Rust — Medium (App Enabled)
PetSafe’s SmartDoor Never Rust offers selective entry and exit with app control. It enables multiple custom schedules per pet, ensuring routines stay consistent while wildlife access remains restricted. This model is designed for households needing remote adjustments and precise access management across a small to medium group of pets.
AJKJ Smart Electronic Pet Door — Small (3 Modes)
The AJKJ model offers three modes: Locked, Unlocked, and Automatic. It uses an intelligent sensing door that detects your pet’s smart key for entry and exit, enhancing security for small to medium pets (up to 35 lb). Adjustable closing times and the option to add more pet keys make it adaptable to growing households. Keys are sold separately and the door supports multiple pet access within a single unit.
Buying Guide: Key Purchase Considerations
Security vs. convenience: Smart doors balance ease of access for pets with protective features like auto-locking, selective entry, and wildlife deterrence. Consider whether you prefer collar-activated, app-controlled, or sensor-based entry to match your home’s security needs.
Pet size and door compatibility: Choose a door that accommodates your largest pet’s weight and build, and verify whether your door or wall opening supports the model’s dimensions and tunnel depth. Aluminum frames tend to resist warping in harsh weather.
Installation and remodeling: Some models fit standard doors, others require wall installations or sliding glass doors. If you have an interior wall or exterior door with a non-standard thickness, confirm the door’s adaptable range and any kit requirements.
Power source and maintenance: Battery-powered doors need regular battery checks and changes. Some models provide faster access via app control or ultrasonic sensors, while others rely on manual scheduling. Consider maintenance intervals and replacement part availability.
Multiple pets and scheduling: For homes with several pets, look for doors that support multiple keys, personalized schedules for each pet, and override options. This helps maintain routines while preventing unauthorized access.
Durability and weatherproofing: A rust-resistant frame, robust flaps, and weatherproof sealing prevent drafts and wear in extreme temperatures. If you live in a climate with heavy rain or snow, prioritize models with reinforced flaps and tight seals.
