i've replaced the ignition switch. that didnt go smoothly so i ended up drilling it out on my 97 ranger 4.0. now i cant get the anti theft system to disarm which in turn is stopping it from starting i believe. also something funny is that the old key does not unlock the doors. any thoughts ? ive looked for fuses to pull but have yet to find one that disables the system. all wires that were there on the ignition are back in place. thx, terry
