I have a problem with my '98 Explorer where the key won't unlock the door
easily.  I always have to turn it back and forth several times before it
will catch and unlock.  It seems to be worse in the winter.  (Not frozen.)
Funny thing is, it's the same for both front doors and the rear one as well.
And same deal with the extra key!  It's very odd and a pain in the butt at
times trying to get it into my vehicle.  Any ideas??  (Besides never locking
it - heh.)  Would a remote be easy to install?  Thanks.
