If my experience is anything to go by Richard getting hold of the EKA code won't do you any good.
It sounds like the key fob has bought the farm. Technozen (Paul) on the Dark Side has a wealth of experience with the Pektron BCU's.
When I had a similar problem I ended up posting both remotes and the Pektron to him and he supplied two new remote coded units which worked perfectly at a very reasonable cost, and with a very fast turnaround.
Bit more info here in the thread I posted when it happened:
