Sounds like the problem that I had with my '94 chev sub k1500, twice!
The first time it was due to a blown fuse. Now I carry a spare 20A fuse when I go off-road.
The second time the electrically controlled/heated, fluid filled actuator mounted on the front diff failed. I now carry a spare actuator when I go off-road.
the actuator is powered when the switch on the top of the transmission is energized. I have had no problems with that switch, or the connecting wiring.
The simplest solution here is to have the ignition barrel replaced. There is so much electronics involved in a modern cars bypassing (hot wiring) the ignition can just cause more problems and usually expensive ones. The barrels themselves aren't that expensive and any good auto electrician should be able to fit and code the keys for it. Sadly it's the fitting that could be the expensive bit.

Your better off finding the cause of the issue. Modern cars have so many sensors and electronics 'bypassing' electrics will become a Huge headache and put a massive dent in your bank account if it goes wrong!
Have you had the battery "Load Tested"? This is where they put a heavy voltage drain on it and see how it copes with it. How old is the battery? A battery can still hold 12 volt but be weak when it's got to supply power to high drain parts like the starter motor. Generally batteries are considered 'Old' when they are over 5 years old, especially on bigger and higher mileage engines.
The fuel pump relay should get power as soon as you turn the ignition to the second position so it can prime the fuel system before you start the engine. I've posted an answer to your Fuel pressure test question and in the video I've attached he shows you a quick "cheat" to test if it's the relay.
The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.

Resetting the airbag light on your Chevy Silverado should be easy to do. Follow this video to watch it being done in a Chevy Silverado. To start with, you will:
Put the key into the ignition
Turn the key to the "on" position
Wait for the airbag light to turn on
Wait to continue until the airbag light turns off (around seven seconds)
Repeat the same steps twice more
Turn on your engine
After you take these steps, your airbag light should turn off. If it doesn't do so, then you should consider taking your vehicle in for diagnostic testing.
If the airbag light remains on, it could mean that something in the system is faulty. That could mean the airbag, the computer wiring, or another issue. Oftentimes, when the airbag light comes on unexpectedly, it is because of interference with the switch.

It may be because of a bad fuse, so first replace the 20-Amp fuse located in the instrument panel fuse box. If that does not solve the problem, check for:
1. Broken switch connection
2. Broken switch
3. Broken or weak wiring
4. Broken circuit
5. Faulty heating pad
If this sounds too overwhelming, it would be best to take your car to the dealership for a quick fix.

If you get a 4 foot length of 1\4" clear plastic hose, you can put one end in you ear and use it as a stethoscope to track down the humming. The closer you get, the louder the noise will become.
