Intermittently, the key may not start the car or release from the ignition. If it is excessively worn, replace the key. If the new key doesn't work, replacing the lock cylinder including tumblers should correct this concern.Google+

My key would not turn the ignition. I would have to wiggle it back and forth till it started. No problem taking the key out. I replaced the lock cylinder. Works fine

my tumbler sticks also,, so I leave a key in it at all times so I don't get stranded. Pain in the arse.

I was told by my mechanic that the shape of the key with the keyring hole on the side of the key rather than on the end of the key contributes to this problem. Even though the key is reversible, people always put it in the ignition with the keyring hole facing down because of the weight of the keys, so the key wears on the one side. I was told to try to try to remember to reverse the direction.
