Here is the short answer: key cutting is the mechanical process of shaping a blank key blank to match the exact depth-and-spacing pattern of your lock's cylinder pins. Done right, the new key operates the lock as cleanly as the original. Done wrong — wrong blank, wrong depths, wrong machine — you get a key that binds, wears the cylinder, or snaps in the ignition. If you are in Spring Valley or Henderson and you are saying 'I need a copy of my house key made,' this post explains exactly what a locksmith does from the moment you hand over your key to the moment the new one slides into your deadbolt.
What key cutting actually involves (the mechanism, not the marketing)
A lock cylinder holds a row of spring-loaded pin stacks. Each stack has a driver pin and a key pin. When the correct key is inserted, the cuts lift each pin stack to exactly the right height — the shear line. Every cut on the key corresponds to one pin stack. Key cutting is just reproducing those cut depths on a new blank. There are two ways to arrive at those depths: Duplication — the machine traces your existing key and copies the profile onto a matching blank. Fast, usually under five minutes on a manual duplicating machine. Code cutting (originating) — the locksmith looks up or measures the key code for your lock and cuts a new key from data, not from a physical original. Used when you have lost every copy, or when a key is too worn to trace accurately.
- Edge-cut keys (house keys, most deadbolts): cuts along one or both edges, read by a tracer jaw on a duplicating machine.
- Laser-cut / sidewinder keys (many modern car keys): cuts run down the center of the blade; require a specialized rotary machine.
- Dimple keys (high-security cylinders like Medeco or Mul-T-Lock): round dimples drilled at precise depths on the flat face of the blade.
- Tubular keys (vending machines, some bike locks): ring of cuts around a hollow cylinder — cut on a dedicated tubular machine.
- Transponder / smart keys: the metal blade is cut by any of the methods above, then the embedded chip must be programmed separately — the cut alone will not start the car.
The machines that do the work in Summerlin and across the valley
Not every shop or mobile unit carries every machine. That gap is where jobs go wrong. Here is a plain breakdown of machine types and what each one handles.
| Machine type | Key styles it cuts | Typical on-site time | Requires code? | Who needs it |
|---|---|---|---|---|
| Manual duplicating machine | Edge-cut house / padlock keys | ~3–5 minutes | No — traces original | Homeowners, basic copies |
| Semi-automatic duplicating machine | Edge-cut + some laser-cut | ~5–10 minutes | Optional | Locksmiths, hardware stores |
| Key code machine (originating) | Edge-cut, laser-cut, dimple | ~10–15 minutes | Yes — looks up by code | Lost-key jobs, worn originals |
| High-security rotary machine | Laser-cut / sidewinder automotive keys | ~10–20 minutes | Yes or trace | Automotive locksmiths |
| Tubular key machine | Tubular / ace keys | ~5–10 minutes | No — impressions blank | Vending, bike, storage |
Rhinox rolls a mobile unit stocked for edge-cut residential keys and laser-cut automotive keys. For high-security dimple cylinders — Medeco, Abloy, Mul-T-Lock — those blanks are restricted and the machines are specialized. We'll tell you upfront on the phone if your cylinder needs something outside our standard kit, and we'll route you correctly instead of wasting your afternoon.
Choosing the right key blank: the step most people skip in Henderson and Paradise
The blank is the raw key before any cutting. Every lock manufacturer makes cylinders around a specific keyway profile — the cross-sectional shape of the key channel. Schlage keyways are different from Kwikset. Medeco's M3 keyway is proprietary and restricted. If you put the wrong blank in the machine, it either will not seat in the tracer jaw, or it seats but cuts to the wrong depths. Here's the part most people don't know: hardware stores carry a few dozen common blanks. A full locksmith truck or a key code machine database cross-references thousands. That matters when you are holding a key for a 1990s-era Falcon or a Euro-cylinder deadbolt and the big-box store employee has never seen the profile. For residential security, the Consumer Reports door lock buying guide points out that high-security cylinders use restricted keyways specifically to prevent unauthorized copies — meaning you cannot walk in off the street and duplicate them. That is a feature, not a flaw. If your locks have it, a licensed locksmith is the correct call, not a kiosk.
Step-by-step: what happens when Rhinox cuts a house key on-site
If you are in Green Valley or Sunrise Manor and you need a new key cut for your deadbolt, here is the actual sequence once we arrive:
- 1. Identify the keyway. We look at the profile and cross-reference it with our blank assortment or the machine database.
- 2. Select the correct blank. Wrong blank = wasted cut. We verify the shoulder stop and bow shape before touching the machine.
- 3. Mount both keys in the duplicating machine's jaws — original in the tracer jaw, blank in the cutting jaw.
- 4. Trace the original. The tracer stylus follows each cut depth; the cutter replicates it on the blank in one pass.
- 5. Deburr the new key. Fresh-cut keys have metal burrs on the edges. Skipping this step makes the key feel stiff and scratches the cylinder.
- 6. Test in the lock. Every key we cut gets tested before we leave. If it binds, we identify whether it's a depth issue or a worn cylinder.
- 7. Note the key code if visible. We log it — if you lose this copy, originating a new one is faster next time.
Car key cutting is different — and the dealer is not your best option
This is the strongest opinion I'll give you: the dealership is the slowest, most expensive way to replace a car key. We do on-site in ~25 minutes what a dealer tows in and sits on for days — same key, a fraction of the wait. Automotive key cutting splits into two jobs. First, the blade has to be cut. Second, if the key carries a transponder chip or is a push-to-start smart fob, it has to be programmed to your vehicle's immobilizer. You can cut the blade perfectly and still not start the car if the chip is not programmed to your VIN. Both steps happen on our mobile unit. Learn more about what the automotive key replacement process involves, or see how key fob programming works separately from the physical cut.
When NOT to call a locksmith for key cutting
Not every key situation needs a locksmith. Be honest with yourself about these: Your key just needs a battery. A smart fob that stopped working after you dropped it probably has a dead CR2032 inside. That is a $5 fix at any hardware store — no call needed. You need a simple copy of a common Kwikset or Schlage house key. Any hardware store or key kiosk handles this for a few dollars. If the original is in good shape and the keyway is a standard SC1 or KW1, you do not need a mobile locksmith for that job. Your lock is worn, not your key. If multiple different cut copies of the same key all bind, the cylinder is worn internally. A new key will not fix it. Rekeying or replacing the cylinder is the correct fix — and we'll tell you which one is worth it. You need a high-security restricted blank you haven't authorized. If your Medeco or Mul-T-Lock cylinders use a restricted keyway, copies can only be made by an authorized dealer. That restriction is the point — don't look for a workaround.
Key cutting as part of a larger residential security decision
A lot of calls we get in Centennial Hills and Mountain's Edge start with 'I need a key made' and turn into a real conversation about whether the locks are worth copying keys for at all. Here is the practical framework: If you just moved into a home, do not copy the previous owner's keys — rekey the cylinders. New keys, same hardware, typically less expensive than a full lock swap, and it eliminates every unknown copy floating around. Read more about when a rekey makes sense vs. a full lock change. If you are cutting spare keys for family members, make sure your locks are not so worn that copies reproduce the wear. A fresh rekey and then cut spares from the new key — that is the correct order. If you are running a rental property in Paradise or Spring Valley and tenants turn over regularly, a master key system with controlled key blanks is worth the upfront cost. It centralizes access without replacing hardware every lease cycle. For emergencies at any hour, our 24/7 locksmith line is answered by a real person — not a voicemail box. If you need pricing before we roll, check our locksmith pricing page or just call us and we'll quote on the phone before dispatching.
