Lost the Keys!

If you have time, key blank, and a file you can make your own. The lock is carefully taken apart by taking the cap off the springs and tumblers keeping all in order. A small scribe is used to mark key blank for tumbler positions. Then estimate first groove in key from tumbler length, install one tumbler set, file that position so it works. Repeat for the rest. I taught myself that on my first car, and little money.
