PetSafe Electronic SmartDoor Review 2026

Collar-key activated door with four-way entry control.

Rating: 4.2/5 · $149.99

What we like

• Available in large size — fits dogs up to 100 lbs
• 4-way directional control (in only, out only, both, locked)
• SmartKey activates from up to 3 feet away
• Low battery indicator
• Dual flap for extra insulation

Things to consider

• Requires SmartKey collar fob — extra cost if you have multiple pets
• 4× D batteries drain faster in cold weather
• Larger, less discreet footprint than SureFlap
