My son has a 2005 seabring. When we lock the doors with the remote fob the doors will lock but the horn nor the light come on for the alarm confirmation. The doors do lock and unlock as they should. Any ideas what the problem could be. This is a factory system that come with the car. Thanks

 

Horn "chirps" and light flashes with locking and unlocking can be programmed in or out as you may desire. Read the owners manual to find out how to do this. If you don't have one, download one from chrysler.com.
