The Sentry Safe 3A3–3Z3 replacement keys are designed to fit locks coded within the 3A3 through 3Z3 key series and are commonly used on Sentry Safe and Schwab safes, fire boxes, chests, and storage units. These custom-cut, double-sided keys are precision cut for reliable operation. Due to the limited availability of manufacturer-specific blanks for this newer key series, the replacement key may fit slightly more snugly than the original, but with proper alignment it inserts smoothly and operates the lock with minimal effort. Ideal for homeowners, offices, and facility managers, these keys provide a dependable solution for replacing lost or damaged safe keys.

“Have used EasyKeys several times. Have always gotten the right product, promptly shipped, at reasonable prices. This is my go-to for specialty keys. (PS I work at a hardware store where I cut keys all the time - some locks just require a specialty key 👍)”
