Sargent & Greenleaf Replacement Key Series SGR600 - SGR699

Thanks for your feedback. To clarify, key stamping is not a requirement—it’s a courtesy we provide when possible, but it’s not always applicable depending on the key type or space on the blank.

As mentioned on our site, making keys without the original lock is not an exact science, especially for older or aftermarket parts. We rely entirely on the information the customer provides—if a code is off by even a digit or doesn’t match the actual lock, the key will not work.

That said, we stand by our 100% money-back guarantee to make sure no customer is left paying for something that doesn’t work. If you’d like a refund or replacement, just reach out directly and we’ll make it right.

Best,
Gus
