Cheaper than replacing your equipment.

Thule Lock Cylinders are arguably the most important part of your rack, that is, the part that keeps all your gear safe and secure on the rack. Thule Lock Cylinders are designed in one size to fit many Thule rack parts, so if a situation necessitates new locks, you can buy one package of Lock Cylinders and lock your entire rack with a single key.

Lock it or lose it.

  • Familiarity: I've put it through the wringer

My favorite thing about the lock cylinders is the peace of mind I get knowing that my bikes are secure. It has gotten to the point where the bikes cost more than the vehicle they sit on top of so it's nice having solid locks in there. Very sturdy in a convenient location on the rack and I haven't had any problems with them.

My Thule Sidearm racks with lock cylinders installed. Very easy to install.

Lock it or lose it.

Don't Lose Your Keys!

  • Familiarity: I've put it through the wringer

When my rack is not in use, I leave the keys in the lock cylinder or tape them to the side of the box. Thule should write the word Thule on their keys instead of the generic number stamped on there. Easy to misplace or forget what they unlock!

Get 6 locks so you have only 1 key

  • Familiarity: I've put it through the wringer

If you planning to use it with Thule bike rack and Thule Root pack, I highly recommend to get 6 locks or more so you only have 1 key for the bike rack and the foot pack. I made mistake to get 4 packs for root pack and the purchase additional 2 for my bike carriers. They are not cheap.

can I get a key replacement if I give you...

can I get a key replacement if I give you the barrel key # N 776 ?

Not through Backcountry, no. You'll have to go through Thule directly. Here's the link. http://www.thule.com/en-us/us/support/spare-parts-keys
