recode / decode toad keyfob :(

[AmDaMan]

Hi,

Some scum broke into my locker at the gym today and nicked my keys, keyfob, wallet etc.

I had to use the spare keys and fob to get back in but as my wallet had my drivers license in is it possible to recode my keyfob so the other one wont work? So annoyed right now, you can't have anything these days!

thanks.
