i had a volvo 850 1996, with normal central locking system and volvo guard 2 alarm system.
all doors are unlocked with first push of my fob remote or first turn of the door key.
i have the central locking relay p/n 9128833 installed from the factory.
can i modify to two-step central locking system which only unlocks driver's door on first push of fob remote or first turn of the door key?
thank you
