Confirm the vehicle make, model year, market and lock position, then match the keyway code in the title. Each tool is built for one keyway — two vehicles of the same brand can need different tools.

Fitment check
Not sure this tool fits your vehicle?
Ask the assistant: it checks this listing against your make, model, year and market, and tells you when it cannot confirm.
The SC4-L is the reverse-handing version of the SC4. Same six-pin Schlage keyway, same decode scale — cut for cylinders where the groove runs on the opposite side of the blade. If you have ever pushed a standard SC4 into a Schlage cylinder and felt it ride the warding instead of the pins, this is the tool you needed.
Buy it when the key in hand has six cuts and the groove sits on the left. Not before — because the standard SC4 and the SC4-L look nearly identical in a listing photo.
Which locks this tool fits
- Keyway — SC4, reverse handing. Six-pin Schlage cylinders built with the groove on the opposite side.
- Cut count — 6. Five-cut reverse Schlage work uses the SC1-L.
- Handing — reverse. Compare the blade against the tool before you order; handing is not something you can correct on site.
Reverse-handing cylinders show up on doors hung the other way and on hardware supplied for left-hand operation. The keyway stamp is usually the same SC4 — which is exactly why so many orders go wrong.
What "2-in-1" actually means
Pick and decoder in one body. Tension, lift each pin to the shear line, read the depth as it sets. Six depths later you can cut a key that works in the door without a second trip.
Decode-then-cut workflow
- Check handing first. The groove must run on the reverse side. Doubt it? Photograph the blade against a ruler and use the tool finder.
- Tension and insert. Light pressure, then follow the keyway in.
- Set and read all six pins. Record every depth before removing the tool.
- Cut the key with a key machine or cutter pliers.
- Test, then label the key against the address for repeat work.
Three mistakes that cost the most
- Ordering the SC4-L for a standard-groove door. Handing is the top return reason on this model.
- Assuming "reverse" means a different keyway. It is the same SC4 profile, mirrored.
- Buying SC1-L by mistake. Count the cuts: five is SC1-L, six is SC4-L.
Frequently asked questions
Can I use the standard SC4 instead?
Only if the cylinder is standard handing. On a reverse-handing cylinder the tool will not track the warding correctly.
Is the bitting different from a standard SC4?
The keyway profile is mirrored, not the pin stack. Depths decode the same way once the tool is seated.
Does it fit SC1-L cylinders?
No. SC1-L is a five-pin keyway and takes the SC1-L tool.

Buying guide & support

Buying the right tool
Match the keyway code in the title to the vehicle or lock you are working on. The cut number (5-cut, 8-cut, 10-cut) describes the bitting geometry, not tool quality.

Returns
Return unused items in original packaging within 30 days of delivery. Refunds are issued to the original payment method within 3–7 business days of inspection.
The product title states the keyway and the vehicle families it is built for. Because one brand can use several keyways across model years, confirm year, market and lock position before ordering — contact us if you are unsure.
