Is this compatible with a 2005 330ci ZHP coupe? Currently my car lights flash when locking and unlocking the doors....but I don't hear a chirp when locking so I'm gussing my car wasn' coded for it? or am I missing the siren?
Also, if i tap window or anywhere on he body this doesn't trigger the alarm so I need that sensor you have correct?
Sorry if these seem like stupid questions but I bought my car 2 months ago and just want to make sure I buy EXACTLY what I need and nothing extra. Thanks
