This answer will work for many car. It could be a few different things. Here is what you can try--
*If key won't turn, turn the steering wheel harder to left or right, even if you think it's already turned far as it will go. Once steering wheel is unlocked, the key should turn.
* make sure its all the way in park or neutral
*older cars have to have the gas pedal mashed(some new ones do too)
*bump automatic gear shift with fist while turning key
*next I'd try the battery and here is your warning*****DO NOT SMOKE AROUND A BATTERY BECAUSE THEY CAN BLOW UP, I'VE NEVER SEEN IT HAPPEN BUT IT IS POSSIBLE*****
*clean the battery terminals if there is corrosion(looks like blue sand) on them. Use baking soda and water as cleanser.
*move the battery slightly forwards and backwards.
*move/wiggle the battery cables a little.
* If the starter has gone out, you can get under the car and hit it the starter with a hammer. If it starts afterwards, then you know its the starter. The hammer solution could work just 1 - 3 times. After the 3rd time, I would not trust it to work again. It's not likely but the starter could last years after one hammer hit.
I need to go. I'll try to add more later.
If you are having problems with starting your car, the car stoles on you as you drive or come to a stop sing, the serive engine lights are on, then you have a problem with 2 sensors, camshaft & crankshaft. You need to replace them both. If you take to a mechaniv shop or dealeriship it will cost you between $300-$500.
I and a bunch of my friends had same problem. I fixed my car and my friends car, and then friends of my friends started to call and I began to fix this problem for them at 50% cost less than of a shop/dealer.
