"Key" to my frustration

Bike Looks great and runs like a top; however, the last few times that I have stuck the key in the ignition I have a hell of a time getting the key to turn! It will turn a little and then stops like there is something in the ignition stopping the key from turning. I have been able to keep trying to turn it and after 10 to 20 attempts it will finally turn.

Anyone have any idea what might be the problem?

That happens with BMW locks often. It will turn out to be one of four things:

1. The lock is dirty. Try some lock oil down the keyhole, then insert and remove the key a dozen or so times.

2. The little sliding pieces are worn - so that when the key is inserted they don't move to the correct, lined up position. In this case you can get and replace any of the sliding pieces that are worn. This is futzy work but it can be done.

3. The key is worn. In this case too, the sliding pieces will not be correctly aligned. This is tricky unless you have an unworn key to copy.

4. The switch (not the lock above the switch) has worn contacts or something else that is causing roughness and binding when you turn the key. In this case the switch part needs to be replaced (or repaired - if you are brave and good).

Buckeye:

My locksmith advised me to not use WD - 40; in his experience it may gum up the mechanism. He uses a silicone spray lube called Miracle Mist, which is amazing stuff. Once it's in the key lock, gently work the key from side to side, and hopefully it will free up.

I have to do this every few months in the winter with the tailgate lock on my station wagon, which gets balky from salted mist being pulled in with the turbulence behind the car. The Miracle Mist will free it right up, but you have to be gentle with the mechanism.

I would think that motorcycle ignition locks are going to have a certain amount of misted crud being pulled in over time, with the turbulence behind the front windscreen and bodywork.
