Sounds like the tumblers of the Master Lock Gun Trigger Lock # 90KADSPT are being stubborn and aren't letting you unlock it. You should note that the lock cylinder is spring loaded and you must maintain pressure on the key, to hold it in the unlocked position, when removing the lock.

Sometimes dust and dirt collect inside the lock cylinder. When that happens the dirt can cause the pins to stick in a partially raised position, preventing the plug from turning. In most cases a spritz of dry lubricant will be sufficient to free up the plug and allow you to open your door. Simply spray the lubricant into the keyway and insert the key a few times to work the lubricant into the mechanism. If this method does not work you may need to use a more solvent-based lubricant like WD-40 to loosen the dirt. Locks exposed to the elements sometimes collect a lot of dirt.
