I have a 1962 Herald Mk 1, with only one set of keys. I have always felt it important to have a second set of keys to enable a second driver, and to prevent mislaying keys causing problems. Replacement locks over the life of the vehicle have resulted in different ignition key, door key, boot key, fuel filler key. High St. key-cutting services don't cut car keys. I don't really want to send the keys away. So what is the best answer?
