How to Fix Broken Helmet Lock Question

[calnalu]

Some %#@&!! cager backed into my bike while it was parked on the street. They didn't knock it over but they managed to scratch up the cylinder head cover and dent my Shoei and break the helmet lock holding my helmet. (And, no, they didn't leave me a note telling me they did all this damage. I found out when I went out to my bike. All they left was white paint from their bumper.)

I got a replacement helmet lock but can't figure out how to remove the lock from the old helmet lock mechanism to put it in the new one. It looks like there might be a locking washer or something on the inside but it's hard to see and hard to reach inside there.

Here's a pic of what I'm talking about. Any guidance would be appreciated.

Thanks,

Marty:confused:

Be sure you clean off the white paint with rubbing compound before you decide if you have to paint over anything. It is surprising how effective this treatment can be.

Can't help on the H lock. Bummer

With the key in the old lock, you should be able to depress the last tumbler from the rear (using your fingernail or a sharp object), allowing the lock to slide out.

Thanks, Anton. Unfortunately, this isn't a typical lock unit with tumblers that are exposed. The tumblers and other parts of the key/lock mechanism are contained in a metal casing that turns when the key is turned to move the helmet latch. My problem is getting this whole encased lock removed.

Anybody have other ideas?

If you look in the new lock, you'll see a channel that goes into the lock's new home. If you look on the bottom of it, you'll see a slot. That slot allows a pin from the lock to hold the lockset in place. If you look carefully, you should see a way to insert a paper clip or other pointy object in there to release the pin. You'll need to have the key in the lock when you do this. Insert the pin, turn the lock and it should come straight out.

That's how all the other BMW locks I've ever see have worked, though I haven't seen this setup. Examine your new parts carefully to see if you can find the release access.
