First, make sure you have the correct key.
If the key does not turn, try pulling the steering wheel left or right while turning it - the steering lock may be jamming the ignition switch. If this doesn't help, your ignition switch may be broken.
If the key does turn, check to see if the dash lights come on and whether the starter is turning the engine over. If you see no lights or if you see lights but the starter makes no noise, most likely your battery is dead.
If the engine cranks but does not start, check to see if you have gas in the tank. If you do have gas, you need to decide whether you want to continue diagnosing this yourself or if it's time to call your mechanic.
The ignition switch is where you insert your key to start car
Insert the correct key into the ignition switch and start the engine. That should shut the alarm off.
Well, I don't see that it would help it any! There are 2 keys for a reason! Why would you want to insert the door key in the ignition? It surely won't start the vehicle! Unless the ignition is already screwed up and can start with anything! The tumblers in the the locks for the ignition and doors are different! It would be like putting your house key in the car! Won't work!
Insert the ignition key into the ignition and turn it to on, the alarm should shut off.

Yes, a bad coil will prevent the ignition from firing and the engine will not start.
That's a security issue, if your wheel locks and you cant turn the key for ignition, get in driver seat put key in ignition close the doors, lock yourself in the car, and try to start the car.
You don't. The ignition is required to start the car. If it fails you need a new ignition switch.
