Locks have been around for as long as 4,000 years according to reliable sources. Experts say they date back to the free-spirited Egyptians. The Romans got on board later with some of the first metal locks with springs, tumblers, and keys, similar to what we have today. Although most cars today have keyless entry, they still have the key-activated lock pioneered by the Romans. Chances are pretty good you use key locks several times per day depending on your profession and where you live. If you have charge of a variety of facilities or vehicles, keys fill your pockets with access to just about everything encountered in a given day.

Vintage Mustang locks aren't much different from those archaic mechanisms the Romans invented ages ago. They have springs and tumblers inside and are designed to work with only one particular kind of key cut specifically for that combination of tumblers. Over time and use, locks deteriorate to the point of requiring replacement.

There are other reasons for replacing locks, though. Ryan Peart of JGM Motorsports came to us with his lock problem. Seems he lost the door and ignition keys to his '66 Mustang. That's when we contacted Mustangs Unlimited, which sent us every type of lock imaginable for a '65-'66 Mustang-including glove compartment.
