Original Lishi 2-in-1 Tools: Pick, Decode and Cut Faster

Watch an experienced auto locksmith open and decode a wafer lock in under two minutes, and odds are there is a Lishi 2-in-1 in their hand. For most working locksmiths the Lishi is the fastest legitimate route from a locked car to a cut, working key — no drilling, no pulling the lock, no waiting on a dealer key code.

This guide covers what the tool actually is, how it reads a lock, the technique step by step, which automotive keyways to buy first, and how to keep a tool accurate for years.

What a Lishi 2-in-1 actually is

A Lishi 2-in-1 is a keyway-specific tool that combines two instruments in one body: a pick that lets you set each wafer in the lock individually, and a decoder that reads the depth of every wafer once the lock is picked. Pick the lock, read the depths, and you have the bitting — the same information a factory key code would give you — without disassembling anything on the vehicle.

The words Original Lishi matter. The genuine tools, developed from Zhi Qin Li's designs and sold through authorized channels, are machined to tight tolerances with accurately etched depth scales. Knockoffs exist at half the price, and the difference shows up exactly where it hurts: sloppy lifter fit, vague feedback and depth scales that drift from true. A decoder that reads a depth 3 as a depth 2 does not save you money — it cuts you a key that does not turn. Originals hold their calibration; that is what you are paying for.

How the tool reads the lock

Inside the keyway, a lifter rides along the wafers while a tension arm applies rotational pressure to the plug, doing the same job as a tension wrench in a conventional pick set. The lifter's position is indexed against a depth scale etched on the tool body, so every wafer position corresponds to a marked location and every lift height corresponds to a depth number. While picking, the scale tells you which wafer you are on. After the plug turns, the tool switches roles: hold the picked position, walk the lifter back across each wafer, and read where each one sits against the scale. That reading is your decode.

Step-by-step technique

Every keyway has its own personality, but the core method does not change:

1. Insert the tool fully and apply light tension. Less than you think. Heavy tension binds every wafer at once and kills the feedback the tool depends on.
2. Find the binding wafer. Sweep the lifter across the positions. Most wafers will feel springy; one will feel stiff. That is the wafer the plug is binding on — work that one.
3. Lift the binding wafer until it sets. You are feeling for a slight give as the plug rotates a fraction. Do not keep lifting past the set point — overlifting is the most common beginner error.
4. Move to the next binding wafer and repeat. The binding order is rarely front-to-back; let the lock dictate the work order. On a stubborn lock, ease tension slightly and restart rather than forcing anything.
5. When the plug turns, hold it and decode. Keep the picked rotation, move the lifter to each wafer position and read its depth number against the etched scale. Note every position — many automotive locks carry 8 to 10 wafers, and door locks often omit positions that the ignition includes.
6. Transfer the bitting to your cutter. Enter the decoded depths into your code cutter or key machine and cut the blank. You now have a mechanical key generated from the vehicle itself.

A Lishi rewards patience and light hands. If you are muscling the tool, you are already past the point where it can talk to you.

The automotive keyways to own first

You do not need forty Lishi tools to start. A short list covers a large share of the vehicles a North American locksmith actually touches:

• HU100 — GM. Chevrolet, GMC, Buick and Cadillac across roughly two decades of high-volume trucks and sedans. For many shops this is the single most-used tool in the case.
• HU101 — Ford. F-150, Escape, Focus, Fusion and most of the modern Ford and Lincoln line.
• TOY48 and TOY43 — Toyota/Lexus. TOY43 covers a long run of older Toyota product; TOY48 picks up the high-security side of the lineup.
• HON66 — Honda/Acura. Civic, Accord, CR-V and most of the modern range — perennial bread-and-butter vehicles.
• NSN14 — Nissan/Infiniti. Altima, Sentra, Rogue and related platforms.
• HY22 — Hyundai/Kia. A huge share of the last decade of both brands.
• VA2 and HU83 — Euro work. Common French-designed keyways that show up across European applications; add HU66 for the VW group if Euro vehicles are a regular part of your market.

Buy the tools that match your local car park first — a shop in a Toyota town has different priorities than one surrounded by GM trucks.

From decode to finished key

The Lishi gets you a cut key, and on older vehicles that may be the whole job. On anything remotely modern it is half the job: the blade will turn the lock, but the engine will not start until the transponder in the new key is registered to the immobilizer — our primer on what a transponder key is explains why. From there, the programming step follows the standard workflow in our guide to how to program a key fob.

That also means the part matters as much as the decode. A perfectly picked and decoded lock is wasted on a fob with the wrong frequency or chip family. Use Find My Fob to match the exact remote by year, make and model, or pull the FCC ID from the customer's old unit and match it against our catalog.

Caring for the tool

An Original Lishi will outlast the van you carry it in if you treat it right:

• Never use it as a forcing tool. It is a precision instrument, not a turning wrench. If a lock needs muscle, something is wrong — stop and reassess.
• Keep it clean and dry. Grit in the lifter channel ruins feedback. A wipe-down and the occasional drop of light oil is all it needs.
• Protect the tip and lifter. Store each tool in its sleeve or a fitted case, not loose in a drawer with your drill bits.
• Check reads against known keys. Periodically decode a lock you hold a known key for. If the reads drift, retire the tool — a miscalibrated decoder costs more in bad cuts than a replacement does.

FAQ

Are Lishi tools legal?

For licensed locksmiths doing authorized work, yes — they are standard professional equipment, the same category as picks and key machines. Possession laws for entry tools vary by state and province, and they generally hinge on licensing and intent. Know your local rules, keep your credentials current, and document authorization on vehicle-opening jobs.

Do Lishi tools work on every car?

No. Lishi 2-in-1s are built for wafer locks, keyway by keyway — each tool only fits its own keyway, and high-security sidewinder locks need the specific high-security variant for that platform. Some vehicles have no Lishi application at all and must be decoded by other methods. Check the application list for your exact year, make and model before assuming coverage.
