I have a viper car alarm and i lost the remote and i am having a hard time finding that specific one, i was looking around and i found a whole car alarm same model and FCC id as my brain, my question is can i swap the brains so that i can use the brain that is for sale and put it in my car and then just use the remote for that one instead of finding the replacement remote for my car alarm brain ( which is a drag ) and programing it to use my alarms? How does it go by that does the remote transmits to the alarms brain or somewhere else in the alarm?
