Question:
LOOKING FOR A LOCK FOR MY SEARS SPORT 20-SV I COULD SEND YOU SOME PICS ALSO

Hey Chris, thanks for reaching out!
To replace the lock on your Sears Sport SV-20 you're going to need the Replacement Lock Core and Key # SR03807 along with the Replacement Lock Locator # TH03808.
There aren't any 1:1 replacements for your lock system, so you'll need to drill out the rivets and install this new lock system in its place. I don't have any videos of this being done, but there are some online (like on YouTube) that I've seen people walk through the process that you can check out.
What seems to be the problem with the lock?
