HI - odd problems with door locks.
Driver side: key will not lock doors but will unlock them. It will not turn to left (counter clockwise) but does turn to right.
Passenger side door: Key will unlock doors but will not lock them. It will turn to right but not to left.
Rear door: key will not turn either way.
Interior door lock button does lock and unlock doors so problem seems to be lock cylinders.
Tried all my keys, same result.
Lubed locks with graphite lock spray by inserting straw nozzle into key hole. No difference.
Time to replace all door lock cylinders? Looks like door locks slide out after removing screw behind plastic cover on interior side of door?
Thanks for any help! Al
