Vehicle alarm sounding. With all doors shut properly. I push the lock door control on the key 2x to enable the horn to sound indicating the vehicle is locked and secured with alarm as it should. As of 28 oct 2015 I do the same and now alarm is going off as if a door is open or someone is breaking in. All fuses have been checked and are good. Vehicle is parked in garage on level surface. Checked with both car keys to make sure it wasn't a key electrical issue. The red signal light in the car indicating alarm is on flashes more brightly than usual. I would like to be able to secure my vehicle. Thank you for you time.
