This kit includes 6 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.

Thule Traverse foot pack accepts OKS cylinders

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.

I can get my kayak loaded the day before and leave my car outside knowing it is safe with the cradles not being able to unlock snd taken down with side assist by someone else.


Came quickly and as order. Placed locks into my newly purchased Thule Roof rack. Works great! etrailer was awesome with there communicating with me as my original order was back ordered.


Appreciate being able to change the cylinders and get the crossbars and cargo box to use the same keys.


Work perfectly with Thule roof rack


Great customer service and communication throughout the entire process. We have not installed yet but everything came in great condition. Will come back again for future needs!


A simple and effective way to reduce the number of keys required to lock down a bike rack. Installation is quick and easy - make sure you use the generic key for the install (and then save it in a safe place). Key/lock system works smoothly and would recommend.


Purchased these to replace the plastic ones that came with the Thule Rapid System Kit 4072. Following your video they were easily replaced and look a lot better than the plastic ones. Also, it is a lot easier to unlock with the nice keys than a screwdriver or quarter. Only needed four but bought 6 in case I need a spare or in case I want to mount something else later.


Very simple to install. Just stick the master key in the cylinder, push the cylinder into the hole on the rack or the carrier, pull out the master key, then use the regular key to lock it. Very convenient to have all the locks on the rack keyed the same.


Best bike rack ever. Assembly was simple . Loading and unloading bikes are quick and easy. The locking system gives you piece of mind knowing your bikes are secure.


awesome product. fast shipping.


I lost my keys, and this was the perfect solution (add locksmith)

Thanks E-trailer!


A six pack is cheaper the buying by the pair and don't need extra keys. Have other Thule products so no surprises. Delivery time was what was expected.


Shipped and received really quickly. Well packaged and complete. Metal parts are heavy duty (and heavy in weight). Assembly is straight forward and perhaps easiest if assembled right on the vehicle . Good quality machining and welding. Very solid feel when mounted. Just got it yesterday so haven't taken a road trip yet. It does weigh 60 pounds, so installing it on the vehicle will take a bit of strength, or perhaps two people.


Expensive but works


Exactly what I ordered.


I received fast service. The locks are great


Great service


These were easy to install. I’m so grateful they offer these so I can have a single key


It is great to have only one key for all devices.



The product works great & fits nicely.


Very easy to install and very prompt de livery


Great product. Easy to install. Works like a champ.


What amazing customer service


Amazingly fast delivery; great price; excellent packaging

  • How to Remove Broken Key from Thule Lock Cylinder
    I spoke with my contact at Thule, and she did have a few suggestions for you to try. She said some people have had success retrieving broken keys using a paperclip. Try wiggling the key out using the paperclip along the ridged side of the key. I have had luck in the past using dental picks to work broken keys out of a lock cylinder. If enough of the key stem is protruding from the lock, you could also try grasping the key with needle nosed pliers and removing it that way. If you are...

  • Can Thule One-Key System Lock Cylinders Be Replaced Once Theyre Installed
    They certainly can. Just hang on to the control key that's included with the # TH450600 lock cylinder kit. This will allow you to remove the lock cylinders and replace them. To replace a lock cylinder you would first make sure it is unlocked. Then you would insert the change key and carefully pull the lock out of its housing. Pulling the lock out can be tricky. I find that putting tension on the key while in the lock (while pushing up, down, left, or right on it) and pulling out at the...

  • Adding Lock Cylinders to a Thule Circuit Roof Mounted Bike Rack
    Yes, the Thule lock cylinders # TH450200 will work with your Thule Circuit TH526XT. If you would like the 6 pack version of the Thule One-Key system to lock your roof rack as well, it's # TH450600. The lock cylinders will include 2 keyed alike cylinders and it's very easy to install. See the diagram I included and you can use a small flat head screwdriver to remove the cap on your Thule Echelon. I included a video review on each product for you as well.

  • How to Lock the Thule Sidearm Wheel-Mount Bike Carrier Part TH594XT
    I have exactly what you will need to keep your bike, bike carrier, and roof rack safe/secure. In order to secure the bike to the carrier and carrier to the rack, I recommend using the Thule One-Key System Lock Cylinders part # TH450200. If you would also like to lock the crossbars to the vehicle and have all the locks match for the bike, bike carrier, and rack then you can use the Thule One-Key System Lock Cylinders part # TH450600. The bike carrier has 2 locks and the roof rack has 4 locks...

  • Lock Cores for Thule Roof Rack and T1 Bike Rack So One Key Can be Used
    In order to get your Thule Aeroblade roof rack and the Thule T1 1-Bike Rack # TH9041 to all be keyed alike and use one key you would need to change out the lock cores on the roof rack as well as the hitch lock on the T1. To do this you will need to order the Thule One-Key System Lock Cylinders # TH450600, which is a quantity of 6 lock cores.

  • Installing Multiple SnowPack Ski and Snowboard Carriers onto Thule Aeroblades
    The Thule SnowPack Ski and Snowboard carrier, part # TH7326 , is 34-1/2 inches wide overall, making it so that you will have to overhang the sides of the bars by a few inches to fit them onto the bar comfortably. Likely, you'll need to mount them using the T-Track rather than the Speed-Link feet. I contacted Thule to verify that this was something the racks are capable of, and they confirmed that they are, however it will make the racks easier to reach, and therefore easier to open if...

  • Keyed Alike Lock Cores for Thule Racks and Accessories
    I would be happy to help you find a set of keyed alike lock cores for your Thule rack and cargo box and clear up any confusion you may have with the multiple options for replacement and extra keys. If you would like to buy specific numbered cores to match the ones you currently have you will need to purchase them each individually. For example the Replacement Lock Cylinder and Premium Key for Thule One-Key Systems item # 1500004217 is key N217. There are multiple numbers but in order to...

  • Availability of Draw-Tite Hitch Lock and Keyed Alike Barrel Locks for Thule T2 Bike Rack
    You will not be able to use Draw Tite hitch locks with a Thule bike rack if you want all of your locks keyed alike. However, you can get a Thule hitch lock and a set of Thule locks that will be keyed alike. For a hitch lock I recommend the Thule Snug Tite Hitch Lock and Anti-Rattle Device # THSTL2. The T2 has 5 locations for Thule One-Key System lock cores - the hitch lock, the ratcheting bike hooks which grab the bike wheels, and the integrated cable locks that extend out of the bike...

  • Can Extra Locks be Purchased for Thule Xsporter Pro Ladder Rack on 2019 Ford F-250
    Yes, extra locks are available for the Thule Xsporter Pro Adjustable Height Truck Bed Ladder Rack # TH500XT that fits your 2019 Ford F-250, but there are not additional locking end caps. This rack comes with two locking end caps and two locking clamp covers which will keep the rack securely on your F-250. This rack uses the Thule One-Key System Lock Cylinders so if you simply wanted spare lock cores you can order two extra locks with the One-Key System Lock Cylinders - Qty 2 # TH450200. If...

  • Are the Keys and Locks Used with the Thule Transporter Enclosed Cargo Carrier Unique
    First, Thule has many, many different keys numbering in the hundreds for all of their products over the years. Though it is possible someone could have the same key, the chances of it are very low. The lock cores do have to be removed to change the key used in them. You can order key and lock sets in quantities as low as 2, # TH512 on up to 8 sets, # TH450800. They also come with the change key to change out the lock cores.

    To attach your Thule Atlantis 1600 to the roof of your 2012 Highlander, you would use the Evo Raised Rail Feet # TH710401 and the 53 inch WingBar crossbars as you mentioned. The WingBars come in silver, part # TH711400, and black, part # TH711420. The crossbar system is confirmed as being a fit for your Highlander.

  • Recommended Bike Rack Compatible with AeroBlade Edge Roof Rack on a 2015 Chevy Tahoe
    I have the perfect bike rack for you to fit your Thule AeroBlade Edge roof rack on your 2015 Chevy Tahoe. The Thule UpRide # TH599000 fits perfectly with the Edge roof rack and secures your mountain bike by the wheels. I like this bike rack because it uses a unique rateching system for the front tire instead of having to reach above the tire to tighten down a clamp. If you happen to have tires that are wider than 3" then you can install the Fat Bike Adapter # TH599100 which then makes...

  • How To Use the Thule Hullavator on a 2011 Subaru Outback Wagon with the Factory Roof Rack
    If by standard you mean factory then this cannot be used to attach the Thule Hullavator Pro Kayak Carrier part # TH898 on your 2011 Subaru Outback Wagon. The reason for this is that the Hullavator requires a crossbar overhang which the factory roof rack does not have. Instead, I recommend Thule WingBar Evo Crossbar System part # TH711420 and part # TH710401 which will mount up perfectly to the Hullavator on your Outback. The best part is you don't have to remove your factory roof rack either,...

I suggest replacing all your cores so that you only need to deal with one key. Thule One-Key System Lock Cylinders - Qty 2 # TH450200 - Qty 4 # TH450400 - Qty 6 # TH450600 - Qty 8 # TH450800
