# Decoding Explained: Reading the Lock's Bitting Code
> Learn how the Lishi reading pane works, how to extract a bitting code after picking, and how to cut a replacement key from your decoded sequence.
Decoding is what separates a Lishi 2-in-1 tool from every other pick on the market. Any pick can open a door — only a Lishi can simultaneously tell you exactly what the original key looked like. Decoding means extracting the precise bitting depths from a lock's internal wafers without ever seeing, touching, or copying the original key. The result is a numbered sequence — a bitting code — that a key-cutting machine can use to produce a factory-specification replacement key in minutes, directly at the roadside.
This page explains how the reading pane is structured, how to perform an accurate decode after picking, and how to translate your code into a physical key using either manual or digital cutting methods.
## What Decoding Actually Means
When you pick a Lishi lock open, the internal wafers are trapped at the shear line — the exact height each wafer needs to be at for the key to turn. Because the lock is held in a rotated position, those wafers cannot spring back down. They are frozen in position, effectively making the lock into its own blueprint.
Decoding is the act of measuring each trapped wafer's height and recording it as a number. The complete sequence of numbers — one per wafer position — is the bitting code. That code is identical to the information stamped into a key's cuts. You have, in effect, read the key from the inside of the lock.
You cannot decode accurately while the lock is in the vertical (locked) position. The wafers must be trapped at the shear line, which only happens after the lock is fully picked and rotated. Attempting to read depths before picking will produce false, inconsistent readings.
## Anatomy of the Reading Pane
The reading pane is the etched grid on the face of the Lishi tool. It is not decorative — every line is a precise measurement reference engineered to a 0.01mm tolerance.
### Horizontal Lines — Wafer Positions
The horizontal lines running across the pane represent the individual wafer stations inside the lock. Each line is labeled with a number (for example, 1 through 8 on an 8-cut system, or 1 through 10 on a 10-cut system). When the pointer is aligned with horizontal line "3," your picking tip is physically positioned over the third wafer inside the cylinder.
### Vertical Lines — Bitting Depths
The vertical lines (or numbered columns) running up and down the pane represent the bitting depths available for that lock system. A 4-depth system will show columns labeled 1, 2, 3, and 4. A 5-depth system adds a column for 5. Each column corresponds to a specific physical height — the height a wafer must reach to align with the shear line for that cut depth.
| Pane element | What it represents | Example values |
| ------------------------ | --------------------------------------------------- | ------------------------- |
| Horizontal lines | Wafer position (which wafer in the lock) | Positions 1–8 or 1–10 |
| Vertical lines / columns | Bitting depth (how high the wafer sits) | Depths 1–4 or 1–5 |
| Pointer position | Intersection of current position and measured depth | e.g., Position 3, Depth 2 |
When the pointer rests cleanly at the intersection of a horizontal position line and a vertical depth column, you have your measurement for that station.
## Step-by-Step: Reading the Decode
These steps follow directly after the lock has been picked and the cylinder is rotated.
Maintain the turning pressure on the tension handle so the cylinder stays rotated and the wafers remain trapped. Do not release tension — if you do, the wafers will spring back down and you will need to pick the lock again before reading.
Slide the pointer to the first numbered position on the reading pane. This aligns the picking tip directly above Wafer 1 inside the cylinder.
Apply gentle upward pressure with the lifter arm until it makes firm, positive contact with the trapped wafer. Do not lift past the natural stop — the wafer is already at its correct depth; you are measuring, not moving it.
Look at where the pointer rests on the vertical scale. If it stops cleanly on the line labeled "3," the bitting depth for Position 1 is **3**. Write this down.
Move to Station 2 and repeat the measurement. Continue through every station until you have a number for each position. A complete 6-cut decode might produce a sequence like **2-4-3-1-2-4**. Write the numbers in order — position sequence matters, and a transposed digit will produce a key that doesn't work.
### Example Decode
For a lock with 6 wafer positions, a complete decode reading might look like this:
| Position | Pointer stops at | Bitting depth |
| -------- | ---------------- | ------------- |
| 1 | Depth line 2 | 2 |
| 2 | Depth line 4 | 4 |
| 3 | Depth line 3 | 3 |
| 4 | Depth line 1 | 1 |
| 5 | Depth line 2 | 2 |
| 6 | Depth line 4 | 4 |
**Resulting bitting code: 2-4-3-1-2-4**
This sequence is everything a key-cutting machine needs to produce a working key blank.
## Anti-Glare Reading Panes
Some Lishi tools — particularly the "AG" (Anti-Glare) variants — feature a matte finish on the reading pane surface rather than a polished one. The reading process is identical, but the matte finish dramatically reduces light reflection in bright outdoor conditions such as direct sunlight on a parking lot or roadside. If you do a significant amount of field work outdoors, AG tools make depth lines considerably easier to read at a glance.
If you are struggling to read the pane in low light, position your body so you cast a shadow over the tool face. The etched lines become much more visible without glare or shadow washing them out.
## Reader Tools vs. 2-in-1 Tools
It is worth understanding the distinction between a standard Lishi 2-in-1 and the less common "reader" variant.
| Tool type | How it works | When it is used |
| ---------------- | ------------------------------------------------------------- | --------------------------------------------------------------- |
| **Lishi 2-in-1** | Picks the lock first, then decodes the trapped wafers | Standard workflow — requires picking before decoding |
| **Reader tool** | Decodes without picking — reads wafers in the locked position | Only available for select lock models with the correct geometry |
Reader tools can decode a lock in the static, locked position without rotating the cylinder first, but they exist for a limited range of compatible locks. For the vast majority of applications, you are working with a 2-in-1 and the sequence is always: pick first, then decode. Attempting to use a 2-in-1 as a reader tool on an incompatible lock produces unreliable, false readings.
## Translating the Code to a Physical Key
Once you have your bitting code written down, you have two professional paths to a working key.
The Lishi Key Cutter — sometimes called the Lishi Nipper — is a handheld, plier-style tool designed for field use without power. It is the go-to option when you are working from a compact kit or in a location without access to a van-mounted machine.
**How it works:**
1. Slide the key blank into the cutter's alignment guide, positioned correctly for the make and model.
2. Move to Position 1 and align the cutter to the depth mark matching your first bitting digit (for example, align to "2" for a depth of 2).
3. Squeeze the handle to clip the cut into the blank.
4. Advance to Position 2 and repeat with the next depth digit.
5. Continue through all positions until every cut is made.
The process is rhythmic and manual — clip, advance, clip, advance. A steady hand is more important than strength. A correctly cut blank produced this way will typically work on the first try, and the entire process takes only a few minutes at the roadside without any power source.
The Lishi Key Cutter is optimized for the keyway families it was designed for. Always confirm that your key blank and cutter are matched to the specific vehicle and keyway before you start cutting.
In a modern mobile workshop, the most efficient and precise method is to feed your bitting code into a digital CNC key-cutting machine. Common platforms used by professional locksmiths include the Xhorse Dolphin and the Silca Futura, though many others support the same workflow.
**How it works:**
1. Select the vehicle make, model, and year in the machine's database.
2. Choose the "Cut by Bitting" or "Cut by Code" function.
3. Enter your decoded sequence (e.g., **2-4-3-1-2-4**).
4. The machine's internal database validates that the code is a valid bitting combination for that lock — if a digit is out of the legal range, the machine will flag it before you waste a blank.
5. Insert the correct key blank and run the cut. The CNC carves each cut to factory-specification depth and spacing.
The result is a key cut to the same 0.01mm precision tolerance as the Lishi tool itself — matching the original factory specification. This method eliminates hand-cutting error and produces a key that is virtually indistinguishable from an OEM blank.
If the machine rejects your bitting code as invalid, double-check your decode. A single misread digit — especially on a 10-cut system where many positions are close together — is the most common cause. Go back to the lock, re-read the suspect positions, and compare against the machine's legal bitting range for that model.
For vehicles manufactured after the late 1990s, a mechanically correct key will operate the door lock but may not start the ignition without a transponder chip. After cutting the key, you will typically need a key programmer (such as the Autel IM608 or Xhorse VVDI series) to link the new key's chip to the vehicle's immobilizer system.
