first off you need a key with the chip in the key forget the battrey powered remote entry key fob plastic thing. if this car has an alarm system try locking both doors off and on a few times .without a chip key to match the code in the pcm[computer] it wont run ,it will crank im quite sure though ,and timing belt must be done step by step one tooth off will run poorly 2 tooth off may not start cuz computer senses this and wont wake the fire maker for spark

A 2002 PT Cruiser has a transponder, or chip key. All do. Somebody cut the plastic and car suddenly your car is a mess. He screwed up the transponder

if what you say is ok and no chip needed, get a push button [starter button] any 2 or 3 amp push button , make hot wire to button , A terminal and wire from button B terminal to starter solinoid on top of starter and connect it there to the thin wire comming from ingnition switch. with key on ,push button for crank, key on for fire to run.
