westwoap1980 Posted November 3, 2021 Share Posted November 3, 2021 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!
