We got these to use extra on hand for our security gate. In order to program them, I had to look at my security gate instructions and follow those.

In order to program them, I had to look at my security gate instructions and follow those. There did not seem to be adequate instructions with the fobs. If you are using them on a similar device, you have to go  to the box, open up the box and put in codes,  using the code on the back of the fobs, and then holding down as instructions say inside my security box. Was only easy to do once I  was reading the instructions from my security gate box
