I have a 1992 Lexus ES300 which has gone some major audio replacements. I got a Kenwood Excelon KDC-X395 for the old stock head unit. Now my alarm won't work, I see the light flashing but I try thongs to set off the alarm and nothing. I know this is what is causing the problem but how would I go about fixing it? Thanks for your help!

 

My alarms always a bit weird in that it doesn't work on the front doors all the time.
Lock yourself inside and try the rear doors. I replaced my stereo so it might be a similar problem...

 

Ok thanks, but if someone decided to break a window to break in would it go off or no?

 

No idea, hopefully ill never have to find out :s
