Customer Service at etrailer is par none, both before the sale and after. I had an unpleasant experience elsewhere buying and installing a roof rack for my old Prius. After a few days of frustrations, I sent it back to that old online store. This time, I contacted etrailer to see what ALL I needed to install a rack on my new 2018 Honda CRV. They sent me the part numbers and a link to purchase. Viola! After they arrived, I had difficulty with one of the parts (at 69 yo my hands are not too strong or flexible) and contacted etrailer. They sent pictures and more thorough instructions on installing the rubber strip. Another VIOLA! I'm so very happy with my total experience at etrailer. Customer Service, truly, is not better any where else I have made online or brick-n-mortar purchases. 642341

The lock mechanism on my Thule Frontier roof box was hard to turn, box is 10-15 years old, replaced the lock mechanism on box and replaced locks on bike rack so they were all keyed the same. Bike rack locks were easy to replace but I had to do a little research on the roof box, the key has to be in the 2 O'clock position to extract. 725940

I received everything I ordered and on time. While a number of items on Thule's site was found to be out of stock, after calling etrailer's customer service they had all the parts I was looking for so I was able to finish my project before our trip to FL. I relied on parts from etrailer to come thru. So Kudos to all at etrailer customer service, they are truly well versed in their trade. When looking for parts I will go to etrailer first from now on.

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! 658814

I have recently purchased the Aeroblade Thule roof rack and a nice Thule roof box. The prices at etrailer are fantastic and they ship really fast. The roof box came by truck and was easy to coordinate. The videos made installation a breeze. The customer service is always great. I had some questions and the etrailer rep were knowledgeable and courteous. I am an etrailer fan and love the very wide selection of merchandise. etrailer... It's not just for trailer hitches anymore... OK I did get my trailer hitch there last year and that had a good installation video too! 603818

  • Lock Recommendation for Locking Thule Hullavator to Thule Aeroblade Roof Rack
    To lock the Thule Hullavator part # TH898 to your Thule Aeroblade roof rack you'd need the # TH450400. This comes with four matching lock cores. Two that you'd install in the Hullavator and two that you'd install in the roof rack to lock it to the vehicle.

  • Recommended Roof Rack for 2016 Toyota Corolla to Carry a Kayak
    I'm glad we were recommended and we can absolutely set you up with an easy to install and use roof rack and kayak carrier for your 2016 Toyota Corolla sedan. It is also really smart to go with a roof rack because transporting a kayak on a sunroof with foam blocks is pretty risky. The roof rack I recommend for your '16 Corolla consists of: - Thule WingBar Evo Crossbars # TH711420 (Black) OR # TH711400 (Silver) - Evo Clamp Feet for Thule Crossbars # TH710501 - Fit Kit for Thule Evo...

  • Lock Cylinders Needed for the Thule Crossroad Foot Pack 450
    The 4 pack lock cylinders # TH450400 is what you want to add locks to the (discontinued) Crossroad Foot Pack 450. Thule lock cylinders are actually universal so if you end up getting a new vehicle and you need a different foot pack you can simply take the included change key to move the cylinders.

  • Recommended Locks For Thule 460 Podium Rack
    For your Podium rack we do not offer a replacement bolt with tamperproof heads. I recommend the Thule One-Key System Lock Cylinders, part # TH450400. This set comes with 4 cylinder locks and keys that unlock all of the cylinders. Cylinder locks can be a deterrent to theft when installed, providing more security, and giving you more peace of mind. I have linked you to a product review video for these locks.

  • How to Order Replacement Keys for a Thule Roof Rack
    We can't sell Thule products to anyone in Canada, but I can tell you that to get replacement keys for the roof rack you have you will need to get the number stamped on the lock core and with that you will be able to order replacement keys from a Canadian Thule dealer. For example, if your lock core says N142 you would need replacement key part # THKEYN142. Notice that the last 4 digits of the part number are the key number stamped on the lock core.

  • Best Roof Rack Recommendation for a 2009 Honda CR-V

The Edge racks are through bars like you said you were interested in where the bar does not extend through the feet of the rack and instead has a low profile factory look. You would need part numbers: # TH7602-TH7602, # THKIT3042, and for locks part # TH450400. For the money you can't beat this rack based on the style you are looking for.

    The Thule One-Key System Lock Cylinders # TH450400 referenced in your question are designed to work with any Thule racks, accessories and roof-rack feet and will work great on your 634 Sonic Cargo Box. If there are locks already installed on the cargo box, you will just need to remove the existing lock cores using the included control key. This set comes with 4 cylinders and two keys. I have attached an installation video for you to check out.

  • 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...

I'll list out the parts needed to add a Thule roof rack for both roof types, and I confirmed these fits with the manufacturer for you: Naked Roof - Thule WingBar Evo Crossbars # TH711420 (Black) OR # TH711400 (Silver) -...

    When you go to change the lock cylinders on your roof rack to the cylinders of the Thule Locking Cylinders 4 Pack # TH450400 you will insert the included universal change key into an unlocked cylinder that is currently in your roof rack and then remove the cylinder. It may take a little bit of wiggling for the cylinder to work itself loose, but when the change key is inserted into the lock cylinder the cylinder will be free to slide out. Next, you will insert the change key into a cylinder...

  • Can I Use the Same Thule Roof Rack on a 2017 Subaru Forester and 2009 Honda CR-V
    We do not have a way to add raised side rails on the roof of your 2009 Honda CR-V but I do have a solution for you. From what you told me it sounds like you are using the (discontinued) Thule Square Load Bars THLB50 and the (discontinued) Crossroad Foot Pack 450 on your 2017 Subaru Forester. Your CR-V won't use the same foot pack but you can use the (discontinued) Podium Foot Pack TH460 and the Fit Kit # THKIT3042 on your CR-V and then you will just have to swap the square load bars...

  • How Does Plastic Lock Core Cover Remove From Thule Racks
    There is a small gap between the plastic cap and the outer edge of the lock core hole that is just large enough to allow you to insert a small, flat tool such as a flat head screw driver. Once you have the tool inserted, you will pry upward forcing the cap out. Check out the link to a similar question that I attached for you that has a video showing how to remove the plastic cap and insert the lock core.

  • Way to Lock Thule Roof Rack with Gutter Mount
    If you have a Thule gutter mount roof rack why not instead replace the plastic cores with lock cores like with the Thule One Key System part # TH450400? This would give you the anti-theft deterrent you want and wouldn't require you to remove any portion of the rack.

    You can use the same Evo raised rail feet, part # TH710401, from Thule to fit the SquareBars on both your 2010 Ford Escape and 2007 Ford Explorer. However, they do need different length SquareBars; use the 43 inch bars, part # TH712100, for the Escape and the 47 inch bars, part # TH712200, for the Explorer. Then you can use the lock cores, part # TH450400, on the feet. As long as the weight of both kayaks remains under the weight capacity of your vehicles roofs and the widths of...

This 4 lock system is designed to fit the empty lock core sockets in your Thule rack, and uses one key for all locks. I have also included links to some of our product pages of items that would work for a roof rack system.

    The new Thule SquareBars recommended for your 2015 Toyota RAV4 are the 53 inch bars, part # TH712400. To mount them to your raised rails you need the Evo raised rail feet, part # TH710401. The Thule One-Key System Lock Cylinders # TH450400 are sold separately. So you need to purchase them if you want to be able to lock your roof rack. I am including a review video of the Thule One-Key System Lock Cylinders as well.
