The key ring holder on mine has broken and as it seems to be a reasonably well-sealed unit I don't particularly want to drill more holes through it.

Toad are asking £65 for a replacement - is this reasonable?

Hmm, just called London car alarms and it's £67 picked up, £80-odd delivered, so may be this is standard....

Seems abit madness to pay that much for a fob Simon. Better off installing a whole new set.

Agreed about the madness. In the end I found space to drill a tiny hole just outside the seal to thread a single coil ring through
