Sun St EC2, near Crown Place, across from Starbucks, by the Boris Bike racks?
Describe it and it’s yours 
Is it a BMW S1000RR key?
its has a long metal bit with a plastic part that you hold. is that right? can i have it? 
Sorry - forgot all about this 
It’s not a beemer key sadly, and yes Jaime, you can have it if you want, since no one else does.
Where would you like it? 
In the ignition of the bike it’s meant to be in. Let me know when you found it
