When I try to open the door with the remote key or lock it, the horn blows twice. I was told if I turn the car on and then try, it will reset the key, but nothing has worked. The inside lights don't work anymore as well.

It sounds like an issue within the security system. The system scans to ensure that all ‘doors’ are closed. Try this first: Verify that the center console, glove box, radio, and front & rear deck lids are closed securely. If any of them are ajar, then the system will beep to alert you. If all are closed and you still have the issue, then there may be a bad sensor that needs to be replaced. Additionally, the fault will need to be reset.
