Keycard Issue

Read numerous threads on this and my issue sounds similar but I want to be sure before going to Renault.

Recently my keycard has not been working but only when I try and open in it in the morning so I have to wait until it does, it then asks me to insert card once it does open, is there a slot on a 200? Eventually it works after waiting.

The car is a 62 plate 200 so is it likely that the battery in the card is flat on a newish car?
 
In the same pocket as my wallet, not near my phone. Still does it when the card is out of my pocket and in my hand.
