Video Transcript for SportRack Roof Box SR03807 Review

Speaker 1: Today, we're going to take a look at the replacement lock core and the key for the Spore Graph Explorer and the Tooley Sidekick Cargo Box and it's for a quantity of one. Now, this replacement lock core and key will fit the Tooley Sidekick Roof Mounted Cargo Box, part number TH682, and it will also fit the Spore Graph Explorer Cargo Box part number A90095 comes with one key. You can see the way this opens it. You just put your key in there. Turn it. And it'll unlock it, and then if you turn that, it'll lock it.

So, the top part of your cargo box, in other words, the top part will open up and when you push this down, you just turn that to lock it, and it'll lock the top section of the cargo box to the bottom section.Now, it does come with one key and one lock core. Now, if you do end up losing the key, it is stamped. The number of the key 2806, is also stamped on the lock core. 2806. So, you just use that number.

You can order. We do sell that key separately if you need an extra one. It's part number THAEYN2806.But that should do it for the review on the replacement lock core and key for the Spore Graph Explorer and Tooley Sidekick Cargo Box.

While traveling to New York I left my Cargo Box key back home. I tried to drill the lock and damaged it. Later somebody helped me to open it without key. Thank you for sending two locks. I replaced them. Pics attached

Thank you for sending me two instead of one. I replaced both. It’s working great


delivered as promised, i replaced the locks on my x-cargo with SR03087 from etrailer and they fit perfectly! great quality. Thank you!
so happy to get my car roof cargo securely locked again!



Excellent! etrailer replacement parts are the best!


Super fast shipping. Great customer service. The locks I ordered fit and we're easy to install. Thanks.



The locks are great. They were easy to install and are working fine.


I bought a sears cargo box and of course after being in storage for years from previous owner there was no keys for lock...instead of ordering replacement key I drilled lock only to find out that lock assembly is no longer available...saw this product as a replacement option and it is very simple and easy to install...and at 10 bucks it is well worth it!


my friend was very happy. now she can lock up her box. thanks


This is 2nd time ordering from e-trailer, for locks and latches.
Every time has been fast and accurate service, products description
is accurate so no guess work, product description helps a lot when trying to match hard to find parts!!!


They work great! The only thing I noticed is the bezel on the front is too long and doesn’t fit flush against the top. I had to trim about an 1/8” off the bottom at the angle the plastic is to make them fit flush, other than that they are great!!


This replacement core is very heavy duty compared to the original core lock that came on my torpedo tube car top carrier. Replaced it with this product and am entirely pleased.



It is working just fine, no problems encountered.


Do not order this for the Cargo Box XL from Sears. It will not fit and you will need to cut off the rivets to replace the lock on the cargo box if you did have the right part.


Just recieved the replacement lock and the key. The key works properly in the other lock in my roof top box. the thread on other lock in my rooftop box while being removed(because both old keys were lost) became stripped and had to be replaced. upon receiving the package I replaced the damaged lock and the box is in propre working order.



Locks work great but the box has outlived its usefulness because the plastic box is breaking where the hinges connect to it.


it was a good product easy to install it was good to replace my old broken lock from my thule cargo sports 20


Just installed 2 new
locks in 15 minutes


Conforme à ma commande et livré rapidement merci


Does not work as a replacement for X-Cargo Sport 20, as advised. The old lock came from both sides (middle in photo) while the new one only comes from one (far left in photo). This makes it so that you cannot lock the new lock since it must be turned parallel to lock, but where it would lock does not allow for it to be turned parallel because it is too wide (far right in the photo). Not a great description, but very frustrating after all the work put in to replace the lock.

I have contacted the manufacturer and looked into this situation about this lock. Unfortunately, they have confirmed that this lock that you have ordered is made for Thules Sidekick carrier and is not compatible with the X-Cargo Sport 20. Neither Thule or us have available parts for this carrier. The X-Cargo Sport 20 is an item Thule made specifically for Sears a very long time ago, that carried a very limited warranty and very limited replacement parts.


Right part received quickly. Reasonable price.


Parts fix great,received parts quick.


I purchased two lock and key sets. They both were easy to install and were delivered quickly compared to many other websites. Wish they were both the same key since I replaced both locks on my cargo carrier. Other then that great product and service.


Great replacement part and easy install


Perfect no issues

Great works well and easy to installef


Easy to install, exactly what I needed. accidentally broke my only key from my last lock set and this was the best solution with the most value


The part worked like it should, no comp laints


Had this trailer for some time with no way to lock it up found etrailer through a web search they had exactly what I was looking for customer service fast shipping reasonable priced now life is happy again ride safe and get lost thanks again for the great customer service


Was purchased as a replacement for a Sears cargo box lock. I called e-trailer and they helped me to choose the right lock for replacement. It fit perfectly.


Locks function as they are suppose to. Found out the hard way that I needed new back plates to refit since my cargo carrier was manufactured in 2002. I had to slightly modify (enlarge the mounting hole) to accommodate the lock. Special "thank you" to Charlene for expediting my order to ensure it arrived ahead of schedule due to a family trip. Also, to Katie for following up. I will definitely order from etrailer again due to the service I received.



eTrailer, It has been a year and the parts I ordered have held up to a years worth of traveling. Thank you the outstanding service provided when I purchased these parts.
