TECHNICAL MOTOBRICK WRENCHING In Remembrance of Inge K. > The Motobrick Workshop
K Bike Keys
frankenduck:
Most likely your K bike came from the factory with a 51251453659 folding key. About $12 when purchased from a dealer.
BMW also sells a flat "standard" key with part number 51251233554.(Nieman GKS) About$7 from a dealer.
BMW also sold a 51212315251 key that had a tiny pushbutton flashlight built into it but I think those are long out of production.
Somebody sells these folding keys on Fleabay under part number 51251243275 but I don't like these because they are so short that they have to be folded over to work, unlike the 659 folding key above which will work either folded or unfolded.
Important: All of the above keys are made of steel and should be taken to a REAL locksmith as the key cutting machines at places like Lowe's and Home Depot are not able to cut steel key blanks.
Aftermarket Keys:
There's a few of them out there but the one I've found that most locksmiths have on hand and works well in K bikes is the Ilco SR61N.
The Ilco Y61 also works in K bikes and is slightly longer than the SR61N.
Some key blanks have a shoulder that needs to be removed. (like Ilco SR61N and JMA NE-8)

Great post! I wish I had read it sooner as I found out all of these things myself. The eBay 51251243275 key does in fact need to be folded to work correctly. It's kind of tough for the helmet lock although mine seems to work in my luggage without folding. The SR61N has a nub on it that will need to be ground off unless the locksmith catches it. The Y61 is a much better fit and I found them for cheap at ekeyblanks.com for like $2.50 each shipped. I did find the correct BMW emblem folding key #51 25 1 453 659 at http://www.motorwestmotorcycles.com/shop/index.php?main_page=product_info&cPath=12&products_id=494 for $13.00 shipped.

I always take the bike to the locksmith so I can test the key in all of the locks before leaving. Either that or the gas cap for testing purposes if I take the car since that's easy to take off.

Hey Joe the site says these keys are used on "R" models, worked fine on your K? The real deal if that's the case.

I cross referenced it from other sources. I didn't get it cut yet but it looks right! I'll post here when I do.
