    1994 K75 Lock cylinder

    Yesterday I fired up the K for the first ride of what is turning into Spring in northern VA.
    I tried opening the right side saddle case. The whole cylinder came out. The same key operates ignition and all the locks. My question is, what can I do about this cylinder, walking out of its housing? And how do I keep the same key settings on the cylinder?
    Here's a pair of pics to show the horror.

    Locks

    There should be a flat tab sticking out at the bottom of the assembly. It is spring loaded. If that tab is there then just insert the assembly back into the hole all the way. You'll have to line up that tab with a slot in the hole by rotating the key. Once the lock is completely inserted, rotate it until that tab locks into a corresponding slot. It should stop rotating at this point. Turn the key itself and remove it in the normal manner. The purpose of the tab is to index the lock and keep it from pulling out.
    You'll find a slot or hole in the latch itself where you can insert a small pin to depress that tab to rotate and remove the lock assembly.
    If there is no tab sticking out then you can buy a "universal" lock assembly that comes with enough pins and springs to match the lock to your existing key.

    Agree to this and add, quite often that last locking wafer gets bent out of shape from the lock being forced passed it's stop. Lots of times they fall out and end up just sitting on the top of the saddle bag. They can be straightened out and reused. After inserting back in it's slot it needs to be peened to keep the spring from pushing it all the way back out. If i remember correctly, there is a little step on the wafer that will bump into the peen. I think at least 4 of mine did the same thing, kind of a fragile lock set, not for the ham handed.

    Here's what the retaining tab is supposed to look like:

    It is possible that it is jammed in the retracted position. The key will not move the tab. It should always be in the extended position except when you are holding it in to remove the lock.

    In case you're not thinking it right now:

    Damn! This place is a great resource.

    The bottom tab on mine is missing. I'll look into the case's hole and see if it's hiding in there.
    Otherwise, I will need another lock.
