Back to the key question.......the only solution I have found is a good locksmith.
And, those are hard to find here where I live.
The last one that tried to make a key produced one that just barely worked, plus he broke a
piece on the trunk lock.
The only good , old, lock guy we had around here used one of those little gun type things that I referred to as
"shooting the lock".......it gauged the placement of the pins or something. He could produce a good working
key pretty quick. However, I read somewhere that those tools are supposedly now illegal because they can be
operated by crooks as well as locksmiths.
Found this info on a forensic lock picking site.........apparently they are called "pick guns"
Manual pick guns are spring-loaded tools that resemble a toy gun with a lockpick attached to the front. The lockpick is interchangeable, and referred to as the "needle." To open the lock, the needle is inserted in the lock and placed under all pin stacks. As with lockpicking, a separate tension tool is used to apply tension and rotate the plug. Light tension is applied to the tension tool and the trigger of the pick gun is fired. According to physics, the kinetic energy transfers from bottom pin to top pin, causing the top pins to "jump" in their chambers. If all top pins jump above the shear-line at the same time, the plug can be rotated to unlock the lock.
