what year is the 4 door. try to manually give power to the starter see if makes any noise or tries to turn over... if i remember right (its been awhile since i looked at one) but there should be a remote wire on the starter its a small wire i think it was green in my honda. if i remember right if you add power to that wire it should turn over.. if it doesn't the starter is bad if it does turn over its the shit up by the key the connectors on the ignition wear out.. it happened to me.. the key worked everything else but the starter.. all i did was add a push button starter button and hook it up the starter it worked great all you had to do was put the key in and turn it and then push the start button i hooked up... and you can hide the button so thieves would know were to look for it... they would just think it has some ignition cut off switch
