Do you have another key to try? Make sure you are not on an incline that has the shift linkage in a bind. Try starting in neutral which could mean there is a linkage adjustment needed or a faulty neutral safety switch.
Other than that you might need a new ignition lock cylinder (part the key goes in) or a problem inside the steering column. Most big cities have a mobile lock company that also works on steering columns after a car theft, they would be a good person to call to avoid a tow fee
