I have two (2) Thule Insta-Gater Truck Bed Bike Carriers 501 purchased in March/April, and lightly used. I sold my truck thus I don't need them anymore. I never got the locks for them. My asking price is $115.00 each. MSRP is $169.95.

Here is a link to Thule's site:

They work well, and I never had any issues with them.
