My ignition key is stuck, can't get it out

Thanks for your advise, that was my preference, to talk to a locksmith. This is what happened today. My neighbors son is pretty mechanically inclined he he came over and took it apart to get to the cylinder, which was pretty simple, but had trouble getting the cylinder all the way out. Because the tumblers were all loose inside. His grandson came and figured how to get it free. They ended up removing the loose tumblers, put the cylinder back in. Now I can start it with anyone's key. To get the cylinder out you have to insert a straightened large paper clip into the farthest hole from the key pull the cylinder forward then repeat that procedure in the next hole. If the tumblers are all loose and you can't get the plastic cover off around the stuck key, just cut the stuck key off with side cutter, but leave some of the key to get a hold of.
