Why does the horn on my 2010 Buick Lacrosse sound muffled when I set the alarm?


Asked by takouris Aug 10, 2014 at 06:14 PM about the 2010 Buick LaCrosse CX

Question type: Maintenance & Repair

I noticed today, for the first time, that when I start my 2010 Lacrosse I get a message
that says, "two keys programmed." When I turn the ignition, it sounds sluggish and when
I lock the car the horn sounds muffled. My 5-year old son says he's been playing with the
lock button on my keyfob.
