This kit lets you add new locks or replace existing cores for all your Thule products. These keyed-alike cylinders let you lock your racks, accessories, and other gear with one key. Extra-thick tumblers help prevent forced opening.
Features:
Note: Key numbers should be recorded on Thule's product registration page and written down in the space provided in the One-Key System manual.
Thule's One-Key System makes it easy to secure all of your Thule racks, accessories, and other gear with just a single key. This kit includes 4 keyed-alike lock cylinders that are designed to mount in the empty lock core sockets of your Thule rack or to replace your rack's existing cores. It includes 2 over-molded keys that are comfortable to grip and easy to identify on your key chain, and 1 universal master key for adding or replacing lock cores.
Many Thule products - including roof rack feet - come ready to accept One-Key System cylinders. Just pop out the plastic lock plug, then use the included universal master key to install the new core in its place.
To replace an existing lock core simply unlock it and use the included master key to remove it. Once the existing core has been removed, pop in the new One-Key System lock.

Lost keys to Thule ski rack & ordered these as replacements. Switching out old locks was very easy as shown in the Thule video. Now I can use the extra locks to replace the locks on my Thule bike rack so I only need one set of keys for all my Thule locks.
Once again etrailer had exactly what I needed. Even though the item was out of stock when I ordered it, I got regular updates about when it would be available. The item was restocked quickly and I received the Thule locks well before I really expected them. Great videos provided to show me how to install the locks. Great customer service as usual!
Worked perfectly !
I originally bought the Thule T2 classic bike rack. First of all if you don’t have a platform rack you need to get one. So much easier to use. Your bikes will not get dinged up. I then bought the 2 bike add on for my rack. Because I don’t always need a rack for more than 2 it was nice that I can easily add 2 if needed. Easy to install and remove the add on. Plus you can never go wrong with Thule and e trailer.com!

Still love the rack. It’s the best money I’ve ever spent for a rack. I’m always telling friends how great the rack is and the buying experience through e trailer!
My order was processed very quickly and shipped in a timely manner. Everything arrived in great shape. I am pairing my Thule crossbar kit with a Thule Force XT cargo box to increase my capacity for hauling camping gear for a family of 4 in a 2019 Subaru Forester. The installation and product review videos on your website are very helpful.

We are still using the crossbars and locking kit and they seem to be holding up just fine.
Installed with ease. Secure my racks to my vehicle. Peace of mind!
Car: 4 door Civic Sedan
Ordering process was easy as I was able to search for the set that matched with my vehicle. I originally had ordered locks along with my set, but they were out of stock. But they were very flexible in allowing me to cancel that item and have my rack set processed and shipped right away. Fairly fast delivery, I believe it took about a week or so.
Assembling it was very simple with the instruction manual if you read it carefully, there is also a helpful video if you need it. Had a little bit of a struggle with spacing out the cross bars in order for it to fit my ski carriers that I already had (but I did expect this).
The final product is actually fantastic. Immediately slapped my snowboard into it and ran it out for a drive. Peaked at 70 MPH with no issues of it falling off or wind whistling.
Definitely worth it to spend the extra money to buy quality like this. Even better when the folks selling it do a great job handling your order and shipping!

Review of Entire set: After a year of using this, it still works very well. Easy to take on and off your car and make slight adjustments if needed. Only maintaining is really just cleaning it which is simple enough. No issues with lockingunlocking with the keys. It has definitely helped saved space for my tiny Honda Civic.
Spend the extra money on a product that will really secure your kayak so you don't have worry while driving down the road. I ditched a cheaper no name brand in favor of these and couldn't be happier.

Locks still work fine
These fit perfectly into the clamp arm on the bike rack. Bike thievery is a big problem and these add one more layer of protection on top of a thick cable and lock.
Good product but just, if not more important, was the excellent customer service by the salesperson. Great job!
Very nice same key locks... I have used Yakima for years but went to Thule on my Jeep and am very pleased with the quality of Thule...
Worked as represented. Easy to install.
Great experience...order arrived within a couple of days Thank you for your help.
Five stars for your web-site and service. Even with regular shipping, my items arrived very quickly.
I have been using Thule products for over 30 years. I guess you could say I consider their products to be five star too.

Wow, 30 years?! That is a loyalty if there ever was any :) Kinda has to make a bit of an expert on Thule, doesn't it? What different kinds of Thule gear have you owned over the years?

I spent a bundle on the roof rack and don't want it stolen. The lock system was fairly easy to install. We keep the rack up all year even though we only really need it for a festival we attend each July. We leave the car in a parking area for a week and camp about a mile and a half away. We've never had a problem with potential thieves.

just fine
This is my first Thule product but not my last. etrailer was great to deal with the videos on how to install the product were so helpful. Between etrailer's help and all the reviews that other people had purchased and posted made this a very pleasant purchase and install. I highly recommend etrailer and the complete Thule WingBar system including the keylocks that worked perfectly.
I have bought 3 trailer hitches through etrailer and have been more than satisfied. Easy follow up and great help. When I wanted roof racks, this was the first place I turned. Unfortunately someone tried to steal one of them so I need a replacement part which they got for me right away. When I decided to get locks for them Amy found them for me right away.

Amy knows her stuff! I'll show her your review :) Stinks people who steal are like that out there but at least now you have some locks :)
Thule gear. Aero crossbars and bike rack. Built well and dependable operation. The lock cores and keys are a must. Nothing but quality items and service from etrailer.com.
I was worried that the master key for removing the old locks would work. It worked like a champ! The new locks and keys are OEM Thule - perfect!
2026 Subaru Outback Wilderness fit was not what I expected......Huge gaps.... a lot of wear on the rails potentially....willing to pay for quality....they are just not for me.
Fit perfectly. Definitely piece of mind knowing you have locking roof rails. Thanks for an easy transaction!
Perfect fit, looks great!

Glad to hear, Daniel! And I agree, they look great on there! ^___^ What are you going to be carrying on them?
Key system worked fine. I don't understand why you can't order the key sets by key code. I already had a Thule Pulse with a lock, and had no way of matching my crossbar locks to the lock I already had. It's a bit expensive to either buy a set of 6, and have one too many; or buy a replacement lock for my existing one.
The Thule One-Key System Lock w/4 cylinders actually is used with a fifth cylinder, as I added an extra one to replace the stock lock that came on my Pulse 615 Rooftop Carrier. The attached photo shows most of the manuals for all the various components I used to assemble a total system for the roof of my Jeep Grand Cherokee in conjunction with my DropRack XL.
It took several calls to the great representatives at etrailer to get all the correct part numbers, as my project is very unique. Every call, they took the time to research their database to help me achieve my end goal. The other photo shows the finished product on my rooftop, minus the Pulse cargo box which I removed for driving at my wintertime destination. This project enabled me to make a cross-country trip over this Winter with my RV in tow, and also serves as a great wind diversion around the front of the RV while underway.

Wow, this review made me feel very proud of my etrailer team! Thank you very much for taking the time to come back and write this review. And I have to commend you on your tenacity to see your project through--that is quite the stack of manuals! I am so glad it all worked out. :)

Still going strong! The quality of this roof rack is exceptional. Carries my canoe and kayak with ease.
