Video Transcript for An In-Depth Look at the Replacement Lock Core and Key for SportRack Explorer Cargo Box

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.

My first time working with etrailer.com and I am super impressed!  I don't have any trailers, but working with this company makes me want to buy one just to see what kind of parts I can get from them!  I did a quick google search for a replacement lock for an old Sears X-Cargo roof travel rack and etrailer.com popped up with a lock that looked super similar.  I took a chance and bought it and it's perfect!  The shipping was super fast, the communication was OUTSTANDING, they have videos and helpful product info too! I love companies like this in today's world of robots and people not caring at all, Thank you etrailer.com, especially Lauren A. and Paula T.!!

Good quality product. It just doesn't fit our Sears Sport20 SV cargo carrier. We may be able to modify a part of the carrier to allow it to latch.

We have had some neighbors (what we call our customers) share what kind of modifications they did to make it work in their reviews, some have included some pics to get a better look at what they did. Hopefully you will be able to get some tips from there, if not let me know and I can see what else I can find for you, Lori!

by:
Delivery was quick and prooduct is as posted. However, can't understand why there is only one key with this lock. If a key is made for a lock is it really that much more difficult to make another and include with purchase of lock? Now we have to get a key made - which should have been included in the first place.
by:
The lock assembly and key arrived one day early. Everything fit perfectly. I replaced both lock assemblies on my Sears Xcargo carrier in about 20 minutes. Very pleased with the product and how well it fit.
by:
Easy website to maneuver. Price was excellent and shipping was fast. Will definitely use them again!

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

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!

@Michael Hey no problem! A lot of people still use the Explorer cargo box. Is it still holding up for you pretty well?

Fits perfectly, and came quickly

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.

IT Working fine. It was the perfect fit,better than the original.

I have an old Sears rooftop cargo box with no keys. Not much available for parts for this box due to the age. After doing some snooping around on the internet I found these replacement locks for a newer cargo box that people were saying would work on my box. They fit like original equipment and work perfectly! Thanks for the help!
by:
Product is perfect and delivery was 3 days early!
by:
Managers were very friendly, super quick and help a lot with the right item to choose. I am super satisfied with the service. Wish you all the best and huge success. You are awesome!
by:
It was right on time didn't have to call Great work
by:
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.

Bought these to replace locks on a Thule Sidekick. Thule and SportRack Sidekick appear to be the exact same product. These replacement locks are the exact same as the locks removed from my cargo box. Replacement was easy and locks work as expected.

They worked perfectly

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

Thanks
Worked as should.

Took a little work to sub this assembly for the original Sears XCargo but I got it done! Works great now! Basically, had to move the mating latch to one side so the catch point lined up with the centerline of the hook on the new lock

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!

  • Replacement Lock and Key For a Sears Sport 20SV Rooftop Cargo Carrier
    While we do not have an exact replacement for the lock on your Sears Sport 20SV cargo carrier, I have an image from one of our neighbors who uses the Replacement Lock and Key # SR03807 to replace their damaged lock. I have included the image below for you to see the new lock in place.

  • How To Retrofit the Replacement Lock Core and Key On a Sears Sport SV-20 Cargo Box
    In order to retrofit the Replacement Lock Core and Key part # SR03807 and Replacement Lock Locator part # TH03808 to the top lid on your cargo box you would need to drill out the two rivets for the old lock and then drill a new 5/8" hole for the new lock core. The lock can then be secured in the hole via the included nut. In regards to retrofitting the Replacement Bottom Lock Bracket SR00841 to the bottom lid, I unfortunately don't have much advice on this but it will be similar to the...

  • Recommended Replacement Lock and Key for a Sears X-Cargo XL
    Unfortunately Jared, since the lock mechanism is riveted to the box there is not a direct replacement for your X-Cargo XL cargo box. We have had some customers use the Replacement Lock Core and Key for SportRack Explorer Cargo Box # SR03807 and be successful, but other than that you'd need to replace the entire cargo box.

  • Replacement Hardware and Lock Replacement for a Sears X Cargo Sport 20 Cargo Carrier
    To replace the mounting hardware on your Sears X-Cargo Sport 20 cargo carrier you can use the Replacement Hardware Kit # TH05603 to re-mount your cargo carrier on most factory and aftermarket roof rack crossbars. To replace the lock, you'll want to use the Replacement Lock Core # SR03807. Make sure your lock core looks like this one to know if it will work. These parts will get your Sears X-Cargo Sport 20 back up and running as good as new.

  • Replacement Key for Karrite Explorer Cargo Box
    If you can locate the key number on your existing locks (see photo), we might be able to obtain replacement keys. If the key number shown on your lock begins with the letter N, you can type THKEYNxxxx (with the x's representing the actual key number) into the search box on the home page of our website. If the key you are needing does not show up on the search, please reply with the number of the key you are needing. If it is available, I will have it added to the website for you.

  • Replacement Lock Set for Sears X-Cargo X-Treme Roof Box
    Hey R, thanks for reaching out! *UPDATE IN COMMENT SECTION BELOW* What I've been seeing is that the Sears X-Cargo boxes use the style of lock that matches with the Thule Kit # SR03807 and Locator # TH03808 so you'll need to go with these parts as opposed to a standard replacement Thule lock core. Did your old lock break or get damaged?

  • Replacement Lock for Explorer Jet Bag Cargo Box

However, we do have the Replacement Lock Core and Key part # SR03807 which many customers have been able to make work on their Explorer cargo boxes therefore this is the best option I have for you.

    I looked up your order and found that you purchased the Replacement Key for Thule and Sportrack Racks and Carriers part # THKEYN2874. As long as the locking core on your Karrite Explorer cargo box has "2874" stamped into the face then this key should work for you. If you have a different number on your locking core please let me know what that is and I would be glad to see if we have the correct replacement for you.

  • Replacement Parts for Karrite Voyager Cargo Box
    For starters, the vast majority of cargo boxes and replacement mounting hardware for cargo boxes will not work on factory crossbars for a Nissan Xterra as they are very large in comparison to the standard crossbar sizes that these cargo boxes and replacement mounting hardware are designed for. Unfortunately, I was not able to find any mounting hardware we offer that will work with the Xterra crossbars. I recommend taking a trip to your local hardware store as this will be your best option.

    The Yakima RocketBox Pro 14 Rooftop Cargo Box - 14 cu ft - Black # Y07192 has the nice push button latch with SKS system you are referring to, but unfortunately there is not a retrofit for the older boxes. To lock your box, I recommend the Replacement Lock Core and Key for SportRack Explorer Cargo Box # SR03807 along with the Replacement Bottom Lock Bracket # SR00841 and Replacement Lock Locator # TH03808. This will require a slightly different mounting but will also give you the security...
