Style Name: 4 Pack Verified Purchase
I installed these in the Thule Rapid Traverse Foot Pack. Installation of the locks is really easy, and while installation of these might prevent a passer-by from trying to get the Thule Foot Pack and bars off your car, they won't prevent a thief who is really out to steal your stuff from getting to it. First, to even get the Thule feet to release from your car a thief will need to have the special wrench that is used to tighten down the feet. These locks just prevent the plastic door on the outside of the foot pack from being opened. If a thief has come to steal your stuff with a Thule wrench, there is a good chance he has also brought something to cut the plastic door on the foot pack, which is not made of very thick plastic. Hence, these locks are not going to prevent your Thule gear from being stolen by a sophisticated thief. So, while they may be nice to have I do not think they are necessary, and they definitely are not cheap for four little locks.

I bought the 6-pack of lock cylinders so that my roof rack (4 cylinders), bike hitch (one cylinder) and roof top box (one cylinder) could all use the same key. My boyfriend and I are both engineers and we like to make things as simple as possible. Thule makes this easy!

Almost every product Thule sells is compatible with their one-key/one-lock system. If it isn't, it usually says so in the product description (example: the cable bike lock by Thule). Each cylinder fit perfectly in the product we needed it for- no extra tools or stress!

Brilliant!! Though we might need the 8 pack soon instead.

We got these for our Thule roof racks. We park in not so great neighborhoods so I wanted the extra security. Pro: they do lock well. They come with an extra lock cylinder. Con: if you don't lock them correctly and push them in all the way they fall out so we lost one first time we drove with them on.

Overall good product. Would buy again.

These work, but are very expensive, and a determined thief could easily remove the entire rack, given some time, even with the locks on. It would just slow down the theft, perhaps enough to be a deterrent, so that the thief would move on to the next guy's rack. Sigh...

My keys didn't have the reinforcing plastic that you see here in the pics, and it also doesn't fit exactly into the 460 Rapid Podium attachment. The edge of the key hits against the 460 plastic housing, which prevents you from fully inserting it, and causes unnecessary torque on the key, which is thin cheap plastic. They are already starting to bend, and I can easily see them breaking. For this kind of money, I expected better quality. I also expected to receive what was pictured, not a cheaper version. Unhappy with this purchase, and would have returned if I didn't need this for an immediate ski trip out of state.

The lock cores insert easily in any Thule rack and can be moved between devices if you have multiple. They are "better than nothing" and are a key deterrent for any rack.

That said, they do not strike me as being that secure. I feel like a resourceful thief would defeat them very quickly - whether it be by simply ripping the core out, or maintaining complete set of keys.

I would still purchase them again, but certainly wouldn't go so far as leave my bikes on the rack in say, a hotel parking lot overnight.

Bought the locks for a T2 Classic hitch mount bike carrier and quickly found that the 'Locked' bike could be easily removed by manipulating the bike. Locks and rack have now been returned.

You need to research and order the locks by key number if you want these to match existing locks you have. IE .. no rekeying. Wife want's double locks for her bike ... now she has double keys too. Expensive little buggers.
