Toyota RAV4 II - add remote two button key

[HeXeN]

Hi, RAV4 2004, is it possible to add by OBD used remote key (black, two button) to the car where remote keys has been lost? and only key left is transponder key
I have SBB, x-100pro, ck100, toyota orange dongle.
Do I need new remote or can be used one? also new transponder or used one? During procedure remotes are added or they are done separately?

Hi

Second hand are reusable. Remote and transponder both reusable.
Remote manual programming procedure. Transponder reusable programmed with SBB, x-100pro, ck100 as long as the key you have has master transponder (possibly black key, not grey ), as part of the programming procedure master key required .
If your key is not master key, then you have to replace the transponder in your key with a cloned one

I havent seen car and key yet. Customer says he has left only "service key" without remote. This might be master transponder.
