Funny story regarding keys... I showed up to a friend's house with my 92 XR2 and when I pulled up, he was in the garage working on a 91 XR2. Neither of us knew each other had a capri. If that wasn't random enough, both sets of keys worked on both cars, (but mine runs MUCH better than his
and has half the miles..)
Anyway, Ford key blanks and cylinders are notorious for working with many other keys. If you own any other Ford products you should try this out. I've had lots of 90s fords work with a variety of keys
