EnglishLocksmith Tools: What They Are and How to Choose the Right Ones
Updated
Locksmith tools are the hand and bench tools used to cut and duplicate keys, pick or bypass locks, rekey and repin cylinders, and install or repair lock hardware. Choose them by the work you actually do: a property manager rekeying residential cylinders needs a different kit than a contractor servicing commercial door closers or a shop cutting keys in volume. The categories below map tools to jobs, and the buying notes flag what to check before you order.
The four core tool categories
Key cutting and duplication
This covers key machines (manual and power) plus the key blanks they cut. Blanks are consumables, not tools, but they determine whether a machine is useful to you — a cutter is only as good as your stock of the right keyways.
Mr. Lock lists key blanks as a stocked category, with examples like the ESP ES8 for various ESP cam locks and furniture locks (compatible with Ilco 1502), the ESP IN8 for Yale IN8/Y11 and similar cam or utility locks (compatible with Ilco L1054B), and the Master Lock 81KM for some Master Lock padlocks and locker locks (compatible with Ilco M5/1092VM). Blanks are sold each, and some are also available in 50-packs or box quantities.
Picking and bypass
Non-destructive entry tools. Budget pick sets vary widely in steel quality and profile coverage; match the set to the lock types you expect (pin tumbler, wafer, automotive) rather than buying the largest kit.
Rekeying and pinning
Pinning kits, followers, plug holders, and shims for rekeying cylinders and padlocks. This is the category most tied to a specific brand ecosystem, because pin diameters and keyway profiles differ by manufacturer.
Installation and repair
Tools for mounting and adjusting hardware — door closers, cam locks, padlocks, and general commercial hardware. Mr. Lock stocks repair parts alongside hardware, so replacement components can be sourced in the same place as the tools that install them.
Match the tool to the job
| Job | Tools that matter most | What to verify first |
|---|---|---|
| Residential rekeying | Pinning kit, followers, plug holder, shims | Pin sizes and keyways for the brands you service |
| Commercial hardware service | Installation/repair tools, door closer adjustment tools | Hardware brand and series compatibility |
| Padlock work | Rekeying tools sized for padlock cylinders, replacement parts | Cylinder type (e.g., keyed alike vs. keyed different) |
| Key duplication (shop or mobile) | Key machine plus blank inventory | Which keyways your machine cuts and which blanks you stock |
| Automotive | Vehicle-specific pick and bypass tools | Make/model/year coverage — the most fragmented category |
Manual vs. power key machines
- Manual machines suit low volume, occasional duplication, and tight budgets. Expect more operator skill per cut.
- Power machines suit shops and mobile locksmiths cutting regularly. The trade-off is cost and bench space versus speed and consistency.
- Either way, the deciding constraint is usually blank coverage, not the machine itself. If you can't stock the keyways your customers bring in, the machine's speed doesn't help.
Compatibility checks before you buy
- Lock brands and keyways you actually service. A pinning kit built around one manufacturer's cylinders won't cover another's without adapters or extra pins.
- Blank cross-references. Mr. Lock's listings show compatibility across brands — for example, the ESP IN8 cross-references to Ilco L1054B. Use these cross-references to consolidate stock instead of buying duplicates.
- Pack size vs. usage rate. Blanks sold each make sense for testing a new keyway; 50-packs and box quantities make sense once a keyway proves common in your work.
- Replacement parts availability. For repair work, confirm the parts you'll need are stocked — Mr. Lock carries repair parts as a category, which matters when a job stalls on a single component.
Starter essentials vs. add-later tools
Start with:
- A pinning/rekeying kit matched to your most common cylinder brand
- Followers, plug holder, and shims
- A basic pick set covering pin tumbler locks
- Key blanks for the two or three keyways you see most
Add later, once volume justifies it:
- A power key machine
- Expanded blank inventory in 50-packs or box quantities
- Brand-specific pinning kits for secondary manufacturers
- Automotive pick and bypass tools for the makes you're asked about
Where to source tools, blanks, and parts
Mr. Lock, Inc. has supplied security hardware since 1976 to resellers, contractors, property maintenance, military, educational, government, property management, and corporate clients. The catalog spans padlocks, door closers, cam locks, key blanks, locksmith tools, door hardware, commercial hardware, and repair parts, with manufacturer listings indexed at the top of the site. Pro-Lok appears as a brand index entry, and the key shop handles master keyed and grand master keyed hardware and padlocks — relevant if your rekeying work includes master key systems rather than single-cylinder jobs.
