Hi,
Can anyone help me with this issue please.
I have a 2006 rr sc that refuses to have a working remote .
I have changed batteries on both keys , even purchased new flip key and changed transponder over so key works fine manually but not as a remote fob.
I then changed the RF receiver and no different .
The central locking works perfectly with key and dash button.
I have resynced the keys so many times that my fingers bleed but nothing.
With the IID tool i get the fault B1BO1-87 KEY TRANSPONDER-BUS SIGNAL/MESSAGE FAILURE-MISSING A MESSAGE.
Anyone got a clue how to fix this please

Hi Corky,
Exactly the same thing with my SC!
I've also changed the RF receiver and have the same fault with my BT OBD reader.
The only other thing that I can think of is that my battery is definitely on it's way out and it could be that.
I didn't want to replace it just now, as I'm back at work in the Congo, and didn't want to leave a new battery on a parked up vehicle!!
I'll await the gurus on the forum!!

I'm no expert and I don't know if my experience with my '09 relates to your '06 but here goes.

First, check the fuse. I was having an issue with the glove box not opening and the key remote not locking/unlocking. The fuse in the back of the car was blown.

Second, when I program my keys using the IIDTool the last step of holding the Unlock button and then pressing the Lock button three times is VERY time sensitive. And, the part about releasing BOTH buttons at the same time is also critical! I've blown it many times when trying to get everything working.

If that doesn't help, then I'm of no help at all .

Good luck!
