Product Details
This works with the Cat Mate Small Electronic 254 and 255 Cat Door, Cat Mate 256, and 363 Electronic Cat Door, and the Dog Mate 259 Small Dog Electronic Dog Door. For use by cats and small dogs. The set contains two magnets made by Cat Mate. Not the right pet door collar key for your pet door? Take a look at our full make and model selection of electronic pet door collar keys.
Note: The manufacturer recently consolidated the Cat Mate 256 and 259 products into one model: the Cat Mate 363. The 256 Large Cat Door and 259 Small Dog Door are identical models, so the magnetic collar tags for dogs and cats work for all of the models regardless. The 255 model has been discontinued, but the collar keys will continue to work for this version as well.

Works with the 254!
I purchased this for my other cat when I purchased the 254 door. This works well so far and my cat doesn't notice it too much anymore, I wish this was sold as singles because I only needed 1 collar key
Good to have
I like that they ship in packs of two. Always good to have a back-up in case my cat loses the other one. They work great!
Small and lightweight
They look a lot bigger in the first picture than they actually are (look at the 4th picture for a more accurate size reference). I was afraid they'd be too big/heavy for my cat, but they're - pretty small and lightweight, so no problem at all.
Looks
They look different than the old keys that hugged the collar, but this actually seems to work better unlocking the door.
