hour and a half later and I was not able to to turn the key.  I
instaled a new lock cylinder and it will not start. i also noticed that my
steering wheel does not lock anymore.  When I put in the new cylinder I am
able to shift the shifter with out Pressing on the brake pedal.  I put
the old cylinder back in and the shifter and brake pedalwork normally
but car will still not start so I reinstalled new cylinder.  To make
things even worse I cannot turn the key all the way back to the off
position to get the key out. can you please help me?






JK:
OK. Sounds like the original problem was a bad ignition cylinder. After
replacement, the theft system must be re-learned, or the car will not start.
The other problems sound like the cylinder is not installed correctly in the
ignition switch. If not indexed properly with ignition switch, this can cause
the shifter and not being able to turn key all the way to off. Or possible a
damaged ignition switch. Try removinf the cylnder, and use a screw driver
in the ignition switch to check the functions of the shifter problem. Turn the
inside of the ignition switch clockwise to make sure all dash lights come, as
if turning the key. Them turn back to off position to see if shifter problem
corrected. If so, then the cylinder is not being installed properly. Afterwards,
the theft will still need to be re-learned before it will start.
