Alarm Question

Question if someone could answer for me please.

With normal alarms back in my day the main unit with the siren in was the brain and took the arm / disarm signal .

as alarm works from the central locking can i grab a working alarm unit ( bit thats under the passenger side wing ) from a scrappy for the same car type and just use that . or do i have to get a new alarm and have it coded to the car.

Thanks in advance

I believe that it needs to be a new one and will learn the code from the engine ecu on fitting. Not 100% sure though I'm sure someone will confirm
