etrailer.com is an excellent resource from which to obtain hard-to-find parts like keys. This is the second time I've lost the keys to my Thule cargo box. The first time I lost the keys I went back to [retailer] where I bought the cargo box and wouldn't you know, [retailer[ is just like [retailer]: They can sell you the product, but if you ever need a part for that product you are out of luck. I guess that's the reality of mass retail these days. Thankfully etrailer.com keeps these keys on hand and they perfectly fit by Thule cargo box. This is the second time I've ordered the keys and both times order notification and shipping were "[retailer]-like". That may sound like a strange compliment but that's the level of precision I've seen from etrailer.com. They are like [retailer]: Fast and furious.

Need keys for my Thule ski/snowboard rack which was locked on my car (my son lost the keys). These worked perfectly. Great price and quick shipment! Now the rack has been put away until next winter.

Service from etrailer.com was very professional. I got updates from the time my orders was placed until it was delivered!! Oustanding service. This was definitely one of better shopping experiences I had online!

Thank you!!!

I lost the keys to my Thule Sonic box. I tried replacing the cylinders using some I found from REI but they didn't work. I could not remove the cylinder with the supplied removal key. So I returned the cylinders and did a Google search and found etrailer. Placed an order and received the new keys in just a few days. The keys are brand new, fit, and work perfectly. Etrailer sends order status updates in email so I knew exactly where my order was at every step. The service works as well as anything from Amazon which is very nice. I'm very happy. I had some stuff in that box I really needed to get out without breaking it. Problem solved.

One year later and the keys are still working perfect. As near as I can tell they are an exact match to the keys that came with the Thule Sonic. Its amazing how easy it is to lose something as critical as the key to your travel storage container. I had a wedding to attend with a drive from Austin, TX to Toronto, ON and it would have been really sad to have left the Thule behind. I needed the storage space to help the new couple move some of their stuff back to the States for college. The replacement keys from etrailer.com saved me.

I am glad we had the right key for you Robin! I keep a set in my glove box, and an extra set at home, I too like to misplace things. Did the lost one show up yet? I feel like they always have a funny way of doing so after we get the new one.

by: Bill 05/03/2026

Dealership had this on back order, etrailer had this to me lickity-split! Just what the doctor ordered. Thanks etrailer!!

You're very welcome Bill, I'm glad we could help!

The key works perfectly. I had a car topper that had been sitting in my yard for several years that I wanted to use. I tried every key I could find but could not open the topper. Once I figured out the number key I needed, I ordered a new key from etrailer. The company had great communication letting me know when they received my order, when they shipped it and when I received it. I would highly recommend etrailer for replacement keys.

by: John 09/14/2026

Replacement key fit perfectly and after shipping issues from the carrier (outside etrailer control). Staff stayed attentive to the order, noticed the shipment was stuck in a loop with usps and repackaged a new shipment to make sure I received the product. Highly recommend!! Service is outstanding!!!

by: Saralynn 08/01/2024

Still works perfect!

by: Vickie 09/20/2026

I had ordered a replacement key for my cargo carrier from another company that said it would work but was only terribly disappointed when I received it and it did not. So, I found your company and ordered another key and was so happy when I was finally able to unlock the carrier and get out my gear. Thank you so much! It was perfect!

by: Craig 11/09/2026

The keys that I ordered worked seamlessly. Each & every experience that I have with trailer is always definitely positive. Thank you for your assistance.

Parts Needed to Replace Lock Core of Thule Cargo Box with Core Number N120

Availability of Replacement Locks and Keys for Old SportRack # A28320 Cargo Box
I spoke with my Thule representative about the locks on your cargo box. They could find no record of the part number you provided, which probably means that your box predates Thule's acquisition of SportRack. If your current locks are held on by very thin retaining nuts, the SportRack replacement locks # SR03807 should work for you. Depending on your locks, there might be a replacement key available. If the key number (should be stamped on the face of the lock) is a four digit number...

Is There a Replacement Thule Key Number 520
There isn't a Thule key with the number 520 available, with the closest being 120, the Replacement Key for Thule Racks and Carriers - N120 # THKEYN120. I only bring that up because if its older it may be smudged or scratched and hard to read, which happens quite a bit. Otherwise, if you do have a lock core with the number 520, the best option - so long as the lock core is unlocked and your rack accepts the Thule One-Key System lock cylinders - is to replace the lock. For that you would...
