    I've seen "Faraday Bags" that you can buy to put the key fob into while not in use, but has anyone found a smaller solution? A key fob cover that blocks the signal would be best, but a small pouch would also work.

    Aluminum foil works great as a Faraday cage. You can wrap the fob in foil or line a small pouch with foil and it will do the job.

    They are bluebooth device with 2-way encryption communication

    each signal is different even for the same command, relay wont work

    If your concerned about a model x, just turn off passive entry. Then you need to click a button for it to lock/unlock/etc.

    That doesn't matter to a relay device it doesn't look at the contents it just blindly forwards the communication. No amount of encryption will stop a relay attack. You have to do time-of-flight validations to make sure that the fob isn't actually further away than it is supposed to be.
