Pontiac Grand Am problems with lights and remote?

My left foglight is out, right reverse light is out in the back, and inside dome light is out. All other lights are working fine. Checked the fuses but they are fine. Was going to change dome light bulb but when i hit it the light came on but then went out so idk what up with that. On top of all of the my remote isnt working, change the battery for both keys and still doesnt work, but get this, sometimes when i lock the door from the diverside the horn will sound as if i locked the car with my remote. Can someone help me please. 2001 Pontiac Grand Am. Thanks.
