Hiya, help please I have a 2008 SH forester XT (JDM) and it has keyless entry and push to start, I have one working keyless key and a spare keyless key, any idea how I can program it to have a second working keyless key ?
dealer wants silly money for a 15 minute job (450 dollars) so that indicates its 100% doable and feasible via OBD, or hooking up spare connectors under the dash even ? I have Tactrix OP so any and all ideas please

anyone have a clue on this ? I have found instructions for Suzukis and other variants but a 2litre JDM Forester XT, any help will be welcomed. I have the second key but need to know how to associate it with the car, any help appreciated, thanks !
