  • Large, magnetic collar key for the Dog Mate Electromagnetic 259 and the Cat Mate Electromagnetic 254, 256, and 363

  • Package comes with a set of 2 collar magnets

  • Dog door opens with collar key activation

  • Fits on collars up to ¼" thick and 3/4" wide

  • Collar not included

This set of two large, high quality magnetic collar keys is designed for Dog Mate collar activated dog doors and pet products, such as the Dog Mate 259 model and the Cat Mate 254, 256, 363 model magnetic cat doors. Two keys are included just in case you need an extra one in the future. The waterproof magnet fits easily onto your dog's pet collar. The dog door opens with collar activation only. As your pet approaches the door, the magnetic pet door senses the key, triggering the door to unlock and open. From there your pet will be able to push through the door.

Note: The manufacturer recently consolidated the 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 collar keys work for all of the models regardless.

Installation Instructions

Prior to installation: Make sure that the collar band is no greater than ¼” thick and ¾” wide. If not, the collar band will not fit through the loops on the collar key.

Step 1: Remove the collar from your pet.

Step 2: Thread the collar band through the loops on the back of the small dog magnetic key. On the back of the collar key, it will indicate which direction is front. Face the magnetic collar key towards your pet’s nose when the collar is attached.

Step 3: Re-attach the collar to your pet’s neck.

Step 4: Adjust the collar so that it sits under your pet’s chin, as opposed to the back of their neck.


Can I purchase a replacement magnet for collars for my Dog Mate electromagnetic dog door?

Yes, this one fits models 254, 256, 259, and 363.

Is this a new collar for magnetic therapy?

While magnetic dog collars are said to use magnetic fields to provide pain relief and help treat hip dysplasia, joint pain (especially in the back legs), and severe arthritis, this magnetic collar is not made to treat pain on older dogs. It is a collar key for magnetic dog doors only.

Will this fit my large dog collar?

Yes, this collar tag is made to slip onto your dog's collar. However, Pet Mate doors are not made for larger dogs like German Shepherds and Golden Retrievers. Having a properly fitting dog door is important for the comfort and well-being of your dog, especially as they grow from puppy to old dog. If you have a medium-sized dog, such as a Springer Spaniel or Jack Russell, make sure to measure them carefully. If you have a larger dog, such as a collie or labrador, you might want to check out High Tech Power pet doors, which has consistently earned high customer ratings from owners of large dogs.
