It doesn't lock or unlock i have a 22 xl key want even go in the hole only about an 1/4 inch is all whats the deal I've heard others complain as well. One guy said grease the key it'll slip right in no it want at all anyone know what the problem is id appreciate your input. Open the handle as you work the key in and out plus a little light oil. That worked for me. This is a common problem across all brands.
