02 Suburban with strange problems

Ok I go to start my 2002 chevy suburban this morning and no electrical components worked and it wouldnt start. Today I get home at one and I opened the passenger door and tried startin it again. Nothing no light and no start or cranking. One min later I went to the drivers side to pop the hood and the lights came on inside so I tried starting it and it worked perfectly. Tried it many times after and no problems. I had my oil changed two weeks ago and ever since it has been running strange and making weird noises. What could this possibly be??? I would owe anything to the person that could help me. Thanks
Many autoparts chains will do this test free of charge. But if your battery is 4+ years old you may want to consider replacing if it before winter anyhow.
- bad ground cable or connections loose at battery or other end attach points
- bad key switch
- lost programming in security system not matching security chip in key anymore (try different key)
- bad BCM (Body control module)
- just because you have new battery, does not mean there isn't something wrong with it. ie, could have bad cell, you could have bad alternator, so it's not charging battery.
