Car Alarms: factory alarm, fcc id, chevy silverado

Question
Trying to find out what make is the factory alarm and valet
start for my 2009 chevy silverado  

Answer
The term "factory" means supplied by the manufacturer.
So that would be GM. But my guess is you
have an after market system.

Try using your remotes
to identify it. Go to www.MYFOBS.com
and look up your transmitter using the FCC ID #
on it.

Good hunting.
