You need to determine where the noise is coming from. Check your power steering fluid and make sure it is full. Remove your serpentine belt and see if the noise goes away, That will let you know if it is coming from the engine or an accessory or pulley bearing. If the noise goes away whith the belt removed, check the alternator bearing and pulley bearings. If the noise is still there whith the belt removed, that means it is either in the engine or transmission.

It is not clear whether your key fob continues to work for the passenger side door. If it does not, you should replace the battery in the fob. Such batteries are available at Wal-Mart among the batteries. If the sliding door on the driver's side makes a noise but fails to open when you use the fob, the latch motor maiy have failed. If the cable in the side door has frayed and snapped, this would explain why you can manually open and close the door but the electronics won't move the door. And if while trying to close it manually, the door fails to latch properly, this is why you get an alarm. If the latch motor, cables, or any other components are malfunctioning, it could lead to the door not closing securely, triggering the alarm. Check your latch mechanism and cables. If you can determine the malfunctioning part and replace it yourself, that is cheaper than going through the dealer.

Here are some possibilities you can test yourself. But if none of them resolve your issue, you may need to consult a professional mechanic. Jeff Armer seems to have supplied even more detail. Just how comfortable you are will such procedures may determine just when you choose to go to a professional mechanic. No Crank or Start: This could be due to a weak battery, corrosion on battery terminals, poor starter electrical connection, bad ground connection, or a faulty starter motor. You might want to check the wires to the starter. If the car starts and runs when you jump the starter from underneath, it could indicate an issue with the starter circuit. Key Won't Release: First, ensure your vehicle is in Park and that the steering wheel is not locked. If the key still doesn't turn, try using a spare key, as the original might be worn-out or bent. If the problem persists, you might need to consult a mechanic or replace the ignition switch. Another method to try is to turn the key to the start position, let it fall back to the run position and leave it sit for ten minutes. Cycle the key off and wait five seconds and it should start. The battery has to be fully charged for this to work. Won't Come Out of Park or Won't Read That It's in Park: This could be related to the vehicle's security system. Running a diagnostic check for codes with a scan tool of both the Powertrain control module/ecu and the Body control module could help identify if any codes are stored. The vehicle should crank over in park or neutral.
