@JesseM Hello. Has anyone used Part Number: SR03807 to replace the Sears Lock and had success?

@Scott Yes! We have had many of our own customers report back to us that the # SR03807 lock set does work with most the old sears cargo boxes. Thule used to make the sears cargo boxes back in the day, so their locks and keys will work.

Do you have a replacement lock and key set for cargo carrier lock 2802

@CarolF if you have a 2802 lock core that works you can get a key with # THKEYN2802. Otherwise, you will have to replace the whole thing with the # SR03807 which comes with a random lock core and key.

Scott I beg to differ. We bought the SRO3807 from you and its not even close to what the existing lock for that box is. The "inside" picture above is what the lock mechanism looks like. If you have a Replacement Lock Core and Key in stock we would love to buy them from you as we have yet to solve this problem and now we have a drilled out lock with just a hole left rendering the box useless.

@KendraB You can get the Replacement Lock Core and Key # SR03807 directly from us, and we have a variety of shipping options you can choose from in the checkout process. Aside from that, I honestly don't know where else you'll be able to purchase this.

Where can I get a key? I have a Sears Sport 20-SV cartop carrier and I've lost the key, it is not an X-Cargo, it is the longer lower model. Thanks

The number on the lock is 2806.

@Gerry We may have the key for that. What is your key number?

@Gery Thanks for the information! The correct replacement key for your Sears Sport 20-SV is the item # THKEYN2806. This key is compatible with your 2806 lock core.
