    1977 R100/7 Key Information Needed

    Hey guys, I posted a question a few weeks back about wheel information and got some great information and feedback. I'm hoping I can find something similar once again.

    I inhereted a 1977 BMW R100/7. At some point during the 80s, it got put down into a gravel pile on the highway. It has since had a bunch of undocumented work that may or may not be correct.

    The bike came with two of the small folding grey Nieman keys, like this:

    key5.jpg

    These both work in the ignition to start the bike, but neither of them work in the fork lock, seat lock, or gas cap.

    I also found one of these keys:

    keyfold2.jpg

    It did not work in the ignition. And rather foolishly, I did not try it on the other items (nor can I at the moment because it's in the shop getting new wheels).

    Given this information, I have some questions:

    1. Is this the normal key set-up? I did a search on this forum (no doubt incorrectly) and elsewhere online and wasn't able to find much information on key sets.
    2. The mechanic (Craig Immel) said that I could get a replacement key set as a kit for the bike but that he had not done one in years. Is this a reasonable bit of work to pursue? Where are these kits and how much do they cost? I have not been able to find a full kit, only blank keys.

    My goal for the bike is to be able to use it for long distance travel, so being able to have those locks is more important than I think they would be for the average rider. Theoretically the bike is known to be comfortable and reliable and should be an excellent traveler.

    Thank you all for any direction or advice you may offer.

    My '78 R100/7 didn't come with a key that looks like either of those...not to say they couldn't be correct, but I think they're replacements. I'm second owner on my bike, so who knows...my key could be a replacement. My key works all three items. So, it makes sense that yours, at least one of them, is a replacement.

    If you find that the two keys you have works one or more of the locks, I think you could just move forward with that. I don't see a need to get one key to do all items. As for a "kit", I think you could find a locksmith to make up a key that solves your problems.

    Snowbum has some good info on keys:

    My key is a Taylor key with the "073R" stamped on it.

    The top keys looks similar to my 74 R90S ignition key. ( Maybe its a /6 key?)
    Maybe someone did a swap at some stage?

    At some point in the 70's those folding keys became available. The ignition and seat locks had an identical key from the factory but ignition switches and seal locks get worn out and people change them. If you don't have a good locksmith or know how to file the tumblers to make on key work in both locks you end up with two keys.

    Then there is the steering head lock which is always a fun time... they should also have the same key but often don't.

    In 900,000 miles of riding I have only used a fork lock twice. They are an instrument of the Devil and are not to be trusted not to be a problem under almost all circumstances.

    Fork lock

    I agree with Paul 100% in regard to the fork lock. I tried mine twice and swore at it and never again to use it.

    I have been lucky with my locks on my R80RT as I have always had the same key for it. Of course the gas cap lock quit working years ago fortunately in the unlocked mode.

    My friend just purchased a 79R100RT with five keys! One for each of the fairing storage compartments one for the ignition. One for the seat lock and one for the gas cap.

    I cannot speak for him as what he is going to do regarding this mess. It is his bike.

    Am I mistaken in that a locksmith who knows what they are doing may well be able to convert the locks to one key? Or, will my friend have to look for a lock set from a bike breaker?

    It is bad enough to have an ignition key a key for the saddle bag latches and a further key for the saddle bag mounting brackets.

    Oh, maybe if I bought a new bike I would get one key or keyless! NO Way, I love my odd old airheads too much to convert to the dark side. St.

    Can someone explain to me why the fork lock is problematic? I haven't been able to use it yet.

    I can investigate local locksmiths next, we have a few in the area that are very good. However, I'm not sure how anyone can make a key for 3 locks that currently have none to copy.

    Fork locks are so bad- most all bikes come with them
    I would have to guess that some donít like them as to the danger of not disengaging the device before you head out for a ride. Same basic problem with disc-locks, chains and other mobility disabling devices.
    Itís operator error, not the lock.

    There is a number of ways to make a key for a lock without a key to copy. Itís kinda a lost art but can be done. Depending on the situation, a good locksmith will advise you of the most efficient way to get you re-keyed. Part of the decision will be based on parts availability, which cylinders are in the best shape and so on.
    Good luck.

    I'm like the others...I can't even remember the last time I used the fork lock. Whenever I park the bike for any length of time when on the road, etc., the bike is on the centerstand...and I don't have the stock stand anymore. So, turning the fork to one side to use the lock is difficult. The lock and mechanism can get dirty and greasy on the inside, making the functionality difficult. That's my guess why they're no fun.

    I would think any locksmith can make a key without having something to copy. They should be able to "read" the ridges and valleys required for the lock and then they can figure out the longitudinal slots on the blank. With their expertise, should be a piece of cake.

    Locksmith

    Like all things, finding a GOOD locksmith or a GREAT locksmith is difficult.

    Yes, you can look on the internet or google all kinds of them in a large city.

    In my city of Rochester NY, I had a heck of a time finding a locksmith to just make a key for my R80RT and my R100RS. Of course, once I did business with him, the Rankin curse kicked in and he went out of business.

    While looking for someone to just make a key, I found most locksmiths work on home or non vehicle related locks. I ran into some dumb asses and crooks before I found the guy I worked with.

    Now this was a few years ago and I for the life of me cannot remember the dumb asses or crook's names so I cannot tell you riders in the Rochester Area whom to avoid. Sorry, teflon memory. St.

    This has all been fantastically useful information. I'll see what I can do in terms of reaching out to a locksmith.

    I shoul be getting my bike back within a week or so if I had to guess. Will report on findings once I have anything.

    Which key is the "correct" one for this bike? I take it, the black one?

    This is what my key looks like. Also here's a fleabay link for the key...interesting it doesn't say for BMW so maybe mine is not truly original.

    Black folding key

    I bought folding style keys (in this question post, the black folding one) only a year or so ago. They are on the market along with traditional flat blanks as well.

    Teflon memory prevents me from telling the source of the folding key blanks. It may have been Motobins.

    Be forewarned there are a lot of locksmiths who cannot properly cut the folding keys. Again, in the Rochester, NY area, I cannot recall who cut mine.

    If had been smart, I would have kept the receipt. St.
