Request for help: Anyone have a bike lock they can donate?

I received this request and I am going to donate a helmet and lights but I don't think I have a bike lock I can donate. Does anyone have one they are willing to donate to a good cause? Kids and bikes are such a great thing...

"I’m emailing as a representative of La Casa Norte, a community resource and social justice organization located in Logan Square. I work for our Scattered Site Supportive Housing Program which provides supportive case management services to chronically homeless families all over the city. We were fortunate enough to receive a bike donation for one of our youth who has recently been enrolled in the program. This is a kid who has been through more trauma than the average foot soldier in Iraq. Needless to say, his Christmases and birthdays haven’t been the most pleasant experiences. This bike is a welcome gift, but our program unfortunately does not have the resources available to purchase a bike lock to ensure that it stays in his possession. I’m emailing to inquire about a potential bike lock (or anything of the like) donation from you all."
