About making picks...... Search for Raimundo's guide. He makes simply lovely picks with a few simple (and inexpensive) hand tools. IE A good chainsaw sharpening file (I got mine for 3$US.... and it works very well) and some sandpaper and a chopstick. You want to find either street sweeper bristles or windshield wiper inserts as your material.
About your Kwikset troubles, you may have a mushroom pin, but thats doubtful-- as Kwikset has recently begun to include spool pins from the factory, in positions 2 and 4, if at all if I remember correctly. You may have a mushroom if the lock was rekeyed- then all bets are off.
