November 3, 20214 yr Alright folks I've just recently had my 2 fobs re-paired to my sigma alarm so the central locking and immobiliser is disabled. I want to install a head unit this weekend and will be disconnecting the battery. Will this unpair the fobs again or do I need to put it in a certain mode I.e unlock and immobiliser off then battery disconnected or something else. Cheers all!
November 4, 20214 yr Working on my 2008 models I have not had an issue with disconnecting the battery and having to resync the fobs
November 5, 20214 yr Replaced my 2007 Foresyer head unit and speakers, no battery disconnect necessary.
