Hi everyone, when i bought my car it came with a fob (different to any of the e36 bmw alarm fob i'd seen before) however it didn't work, i later realised that it was because the siren had been taken out of the car, i recently bought a complete 3G mk2 alarm (in the link below) to replace whatever is left of the existing alarm.
Should this just be a simple swap of the alarms and wiring? Or could this cause issues with the immobiliser? I'll be sending it to a auto-spark to get it fitted but i just want to know in advance if there will be any issues or if it will even be possible.
Thanks in advance.
