Hi I'm new my trailblazer I recently bought has the alarm system in it and I disconnected the battery to replace my alternator. When I reconnected the battery the alarm system gos on and I can't turn it off, is there a way to disable the system?.

Should have a valet switch (hopefully) somewhere in the car. you need to find it and turn the ingition and press and hold until it disables the alarm
