puzzler, you need a U-shaped piece of wire with the ends cut/filed at a 30-degree angle, as I recall, to release both sides of the lock cylinder. Do a Search for the dimensions of the wire tool. I used a piece of copper wire from an electrical cable to make the release tool. As with most things, after you have done it once next time is much easier. Be sure to have the key in the proper position when using the release tool.
