Keyless entry remotes opening trunk

Hi.everyone. Quik question. Bought a couple keyless remotes for my 2000 Tauras on ebay(had one, thought I would get a couple more as spares) The remotes have the lock,unlock, trunk, and panic buttons. Programmed all 3 today by turning the ignition on 8 time as per instructions. Everything seems ok except I have looked outside a couple times and my trunk is open. Thoughts?:confused:
