(3 Pack) 3F2 Keys for Sentry Safes
Code compatibility focuses on keys stamped with codes that begin with “3” and end with “2,” specifically 3A2–3W2. This set includes replacement keys designed for safe boxes, storage chests, and file-style safes that use the 3A2–3W2 series. Best for offices or homes with file-style safes using these codes, particularly when exact code matching is required. A limitation is that it will not fit other code series without exact matches.
Best for: Users who need exact-code replacements for 3A2–3W2 safes and file-storage units. Choose this if your lock uses a 3A2–3W2 code and you require reliable, pre-cut replacements.
Caution: Ensure your key code matches the 3A2–3W2 range exactly; incorrect codes will not fit the lock mechanism.
3 Pcs H51 File Cabinet Replacement Key
Code H51 covers several Hirsh, Staples, and related office furniture locks. The package includes three replacement keys suitable for office desks, file storage units, and similar secured cabinets. Best for multi-brand environments where a single code is required across different brands. A potential limitation is the broader compatibility may still require verification against exact lock models.
Best for: Office managers or facilities teams overseeing mixed-brand filing systems that use the H51 code. Choose this if you need a dependable trio of keys for common office furniture locks.
Caution: Verify that your cabinet lock explicitly lists H51 as the key code before purchasing.
S100 File Cabinet Key, 3-Pack
These keys are tailored for Steelcase S100 file cabinets and Chicago Furniture Locks. The 3-pack offers a practical solution for lost or spare office keys for S100-compatible units. Best for: offices with Steelcase S100 cabinets that require a straightforward replacement key. A caution is to confirm your key code is S100 before purchase, as misaligned codes will not operate the lock.
HI17345 File Cabinet Lock Replacement
This lock is engineered for Hirsh Industries cabinets requiring model HI17345 compatibility and offers broad cross-brand applicability with major commercial brands. The set includes two nickel-plated keys designed to resist jamming and endure thousands of cycles. Best for: Facilities with multiple brands needing a consistent keying solution across Hirsh and similar cabinets. A limitation: it is keyed distinct from other brands, meaning it won’t open non-matching codes.
Caution: Confirm the HI17345 model match to avoid incompatibility with non-Hirsh locks.
3-Pack W624 Keys
W624 keys are cut to codes in the W601–W650 range, with compatibility for Hirsh and Staples desks and office furniture locks. The listing includes three keys. Best for: Offices using Hirsh/Staples cabinets with W601–W650 codes needing quick replacements. A caution is to verify the face of your lock shows a matching code stamp for proper fit.
122E Universal File Cabinet Key
Designed for HON file cabinets and 122E code systems, this 3-pack provides replacement keys for HON’s widely used 122E configuration. Best for: Organizations with HON cabinets seeking a straightforward replacement option across multiple units. A limitation is that the 122E target may not fit non-HON brands with similar-looking codes.
Buying Guide
Key considerations help ensure you pick a replacement that fits properly and remains secure.
- Code accuracy: Verify your cabinet’s key code exactly matches the replacement code (e.g., S100, H51, 122E). A mismatch means the key will not operate the lock.
- Brand compatibility: Some codes map to specific brands. If you manage different brands, consider multi-brand options or codes known to be cross-compatible.
- Lock age and condition: Older or worn locks may require a precise cut and nickel-plated keys to reduce wear and ensure smooth operation.
- Security considerations: Avoid master-key style sets unless you need centralized access. Keys keyed to one code reduce the risk of unauthorized duplication.
- Number of spare keys: If you frequently misplace keys, a 3-pack provides ready replacements for several cabinets.
- Installation ease: Replacement keys with uniform cuts typically install without modification or locksmith services.
