Key card died today

[newleaf]

I purchased my first Subaru Forester on Monday, its a 2010 plate 2d Navplus with keyless card.  It came with two keycards.  When i went out today to my car the main key no longer worked although was fine yesterday, do batteries just die so quick?

 

Spare key is fine, I notice there is also a little key you can pull out if Battery dies and drivers door has a keyhole but can you also start the car with a key as i can't see anywhere to insert it.

 

Going along to my local dealer tomorrow, luckily only 5 miles from where i live and rang to check they have batteries in stock etc. and receptionist told me that i would only be charged for Battery unless key needs to be reprogrammed, is this likely if it was working yesterday?

Problem solved Battery was not seated correctly and i must have given key a slight knock and dislodged it further.
