PetSafeSmart Key for Electronic Smart Door

Not as good a quality as the originals that I first bought or came with the door. You have to be carful not to over tighten the battery or it will split the casing and the battery then falls out. For the money paid not the best quality especially when it on the collar of a miniature Schnauzer who loves to play rough and tumble with her brother.

Easy to program my dogs now have access 24-7 without having to leave the dog flap permanently open 🐶🐶🐶👍

Expensive make sure the battery is screwed on tight as it comes off. Watch you don’t loose is when you go out has fallen of my dashchund

Flimsy and not very useful for large playful dog breeds, mine broke each other’s off within days.Too bulky for the collar, especially if you have a smaller dog
