We'd recommend confirming that the Apple TV remote that you have is compatible with the Apple TV that you're looking to pair it with. If your Apple TV remote is compatible with the Apple TV that you're pairing with, we'd recommend checking out the following resource to make sure these are the same steps you're using:

If you see that these are the same steps, and you're still unable to pair the Apple TV remote, we'd recommend that you Contact Apple Support so they can look into this with you in more detail.
Have a great day!
