What to Buy First vs Later
Start lean and add equipment as jobs demand it. Your first three months should focus on the tools needed for the most common calls in your area, then expand based on actual customer requests.
- First (Months 1–3): Pick set, tension wrenches, screwdrivers, basic pry bar set, flashlight, measuring tape, practice locks, work gloves, and tool bag. This covers residential lockouts and basic service calls.
- Month 2–3: Key blank assortment and a key cutting machine if you’re getting residential duplication requests regularly.
- Month 4+: Rekeying kit, pin assortments, and specialty tools based on commercial work you’ve landed.
- 6+ Months: Electronic lock diagnostic tools, bump keys, or advanced pick sets only if you’re specializing in security or commercial access control.
New vs Used Equipment
Buy new pick sets, tension wrenches, and hand tools—used picks are often worn or bent, reducing effectiveness. These items are inexpensive ($50–$200) and precision matters. New key blanks are non-negotiable; used or old blanks don’t fit modern locks reliably.
Key cutting machines can be purchased used if you’re buying from an established locksmith or reputable supplier. Request a demonstration before paying. Hand tools like screwdrivers, pry bars, and measuring tapes are fine used or new; the performance difference is minimal. Avoid used practice locks (you don’t know their condition), and never buy used drill bits or cutting equipment—they dull quickly and you won’t know their history.
