    By the way, note the little transponder chip in the key in the video, might be slightly different design to your key, but if you have one and it's missing you're going to be in a tricky situation I'm sorry to say.

    Its not the keyless entry board is your problem , the lawnmower has eaten the ews passive tag , (looks like a small silicone bar inside the key housing about 1cm long , there should be a slot for it, try autokey but id say a dealer is the only one that can code a new one for you,

    Yeah first I had heard of that I have to say, well that's definitely gone if it was ever there before so that worries me...

    Is the same thing as described above?

    The transponder bead isn't on the PCB, its a separate plastic chip, about 4mm wide and 6mm long.

    It should look like this:-

    It could be still embedded in the plastic casing of the key that broke off or it went flying. If you do find the chip tape it beside the Antenna and it should read it.
