Replacing Ignition Lock & Key

Look at the pic of the switch LAB posted. The hole must line up with the pin to push it down with small pick. If you notice it lines up with the keyslot. If you drill a new hole at that spot (switch in off position - the old hole lines up when the switch is on.) you can remove the tumbler. Take any lucas ignition key and stick it in the tumbler, you will see some wafers sticking up past the barrel. file them flat with the barrel and replace the tumbler and presto. Be sure to replug the holes.

How does one remove the steering lock barrel?

The Mk3 steering lock should be held in position by a small roll pin pressed into the side of the lock boss underneath the yoke. The Mk3 steering lock has to be knocked downwards to remove it which is the opposite way to previous model Commando steering locks, the Mk3 has a Neiman* type lock, so takes a different key blank to the ignition switch.

*(some 850 Mk2/2As were supposed to have had Neiman steering locks-according to the Mk2/2A parts list, but I've never known anyone to say their 2/2A had a Neiman steering lock?)

I just examined my steering lock in an attempt to remove it prior to powdercoating. I could not determine how it was held in place on the yoke as I did not see an obvious attachment like the roll pin mentioned above. It does appear to have a rubber seal around the top of the cylinder but I didn't want to pry it off thinking I might damage something. Any suggestions, it is for a 71.

These steering locks are not very sophisticated but still cannot be removed with out a key. The locksmith I took the bike to was able to make a key right there in their parking lot. He attained the correct blank then proceeded to try and turn the key in the lock. When doing this it made subtle marks on the blank. He would file and recheck until the key worked. He could then determine the correct biting for the lock and make a more appropriate key.

That being said, these steering lock systems are not all that great and for other than aesthetics should not be considered secure.

The pre-Mk3 lock is simply pressed into the yoke. Tap it upwards to remove it.

Thanks for the advice I still have my key so that is not an issue. I'll bust out the ball-peen and give her a couple taps.

(And don't forget there's a seat lock too)[/quote]

D'OH! Thanks LAB,

I had forgotten the seat lock - mainly because I have a Corbin on mine. Is the o/e seat lock easily removed and replaced and are they available? I guess that will make 3 keys for a Mark, er THREE! I don't have a key for seat lock either.

Sorry to ask but I keep my bike at my parents so can't just nip out and take a look during the week- especially when I realise I have left the manual there too :roll:

Many thanks

Yes, it's easy to remove/replace once the seat is lifted, and it still appears to be available from AN: http://www.nortonmotors.de/ANIL/Norton% ... 28&Part=20

It is another Neiman type lock, but just about any BMW Neiman key I've tried in mine seems to work in it. I don't know if the original steering lock key was also intended to fit the seat lock?

Seat lock? What's that, the knobs on the side of the seats that most people don't know what they are for?

Just kidding. Mine is not so exotic.
