Before I changed my locks, my Contour Ignition key (95 had 3 damn keys
) The ignition key to my Contour worked in my moms Escort, which only had one key, so I keep my old ignition key on my keychain for when I drive the Escort around
Her car key worked my ignition too, Now i just have 2 keys, one for door and ignition, and 1 for glovebox and trunk
