Electronic pet door with accompanying Smartkey Electronic Key. You attach the Smartkey Electronic Key to your pet's collar. Using radio frequency technology, the door reads your pet's key, allowing only pets that have access to the door to pass through. Once the pet has passed, the door goes back into the locked position until it detects a key. A very practical door that allows your pets to go as they please, without, for example, the neighbor's cat sneaking in!
It comes with 1 key. You can have up to 5 keys for the same door. More keys can be purchased separately.
You can choose to have the door in 3 different modes: locked, unlocked and automatic. In locked mode the door is always closed, in unlocked mode the door is always open. Automatic mode is when the door reads the pet's key.
