1973 340 sport dart, column shift. can't find the key & need to move vehicle. what is the easiest way to unlock the steering wheel to be able to steer the car and to get it out of Park?

If the door lock matches you could take it out and to a locksmith to have a key cut. Otherwise pull the steering wheel and take the column lock out.

I think you're easiest way is to get a mobile locksmith to come to your house and cut you a new key for the ignition (costs about $75). Using a matching door lock is another reasonable way to do it, but if the guy comes to your house anyway, why bother disassembling the door to take the lock out? Also, without the key, it's very hard to pull the ignition lock out of the column (Chrysler designed that to be tough for car thieves). You need the key in the ignition lock to remove it.

Good locksmiths can make a key by the process known as 'impressioning'. If you're speaking to a locksmith who is unfamiliar with the term don't use him!

In a pinch I have drove the pin out on the steering coupler, disconnected the the linkage at the transmission and moved the car. Maybe not the easiest but cheap and quick.
