Hey guys I'll be upgrading my HU and I was wondering in if doing so will that have any effect on my factory anti-theft alarm and keyless entry? I know on the factory radio it has the little "Anti-theft" light, and I tested the alarm so I know it is an actual alarm and not a stupid little blinking light. But once the factory radio is taken out, will I loose the security and keyless system or is it stored somewhere else. Just ease my mind before I start pullin stuff apart. lol
