Hi, sounds like the battery in the keyfob is not making a good contact with the metal holder .Has the key got wet / damp , as this will create a barrier between battery and contacts that will result in an intermittent contact .
My Zafira key actualy had the battery holder fall off the circuit board , and i had to resolder it back on .But as the solder was breaking away it also gave an intermitent contact .
( if the battery is removed / contact lost -it has to be paired up again and again.
Iff the holder is secure then give the metal contacts and the battery faces a clean .
