Then I read about resetting the fob with the alarm - tried it and it worked - can't understand how it 'unset' itself in the first place when the keys were sitting in my pocket during the match. Weird but at least an easy solution.
The R53 key has a replaceable battery so it might be worth replacing that given the incident you had, it might be a contributor....
