Key fob not working!

[Thrill]

Just got out car and went to lock it sjd the key fob wasnt working. Tried it a good few times and eventually it worked. The battery is relatively new (past few months). The red button was flashing on the key fob too. Any ideas?

Had exact same thing last night - new battery sorted it.
