The most common Schlage keyway is the "C" keyway. For standard residential and light commercial locks, this uses an SC1 key blank (5-pin) or an SC4 key blank (6-pin).
Some of the most common keyways in residential and commercial locks include:
Up for your consideration is a lot of 2 Schlage SC1 5 pin C keyway key blanks. These should fit most locks that Schlage makes for consumer use. To see if this is the keyway that you would use, see the image that lists all of the keyways that Schlage uses.
No, Schlage keys are not all the same. While they generally share a distinct rectangular-ended shape, each key features a unique series of cuts (called “biting”) designed to fit a specific lock cylinder.
A Schlage C keyway is the most common, standard, and open keyway used in North America for residential and light commercial Schlage locks. It defines the specific, complex shape of the keyhole and the corresponding key (often designated as SC1 for 5-pin or SC4 for 6-pin) that allows it to operate.
The most common Schlage keyway is indicated by the letter C. However, Schlage has several other keyways, including E, F, G and L, and therefore we have many hooks holding Schlage key blanks.
Schlage is generally considered more secure than Kwikset, offering superior protection against forced entry and picking. Schlage locks often feature ANSI Grade 1 ratings, thicker metal, and drill-resistant components, while Kwikset focuses on convenience and affordability (often Grade 2). For maximum home security, Schlage is the preferred choice, whereas Kwikset is often chosen for residential turnover and easy rekeying.
Matching a New Lock to an Existing One
If you want a new lock to match your existing lock, you simply need your 5-digit key code. Most retailers can rekey the new lock to match your existing key. Provide the 5-digit key code stamped on the back of your Schlage key to ensure a perfect match.
The primary difference between the SC1 and SC4 keyways is their pin count and length. The SC1 is designed for 5-pin locks, while the SC4 is longer and designed for 6-pin locks. Both share the same groove profile (often referred to as the Schlage "C" keyway family), but an SC1 key is too short to operate an SC4 lock.
The KW1 and SC1 are both widely used for house keys as well as entry to a variety of buildings, and it's important to be aware of their differences should you need to replace them.
For a true piano experience, 88 keys are highly recommended. They offer the full range needed to play most classical and modern sheet music. However, if you are strictly playing pop, synth, or producing music—or have limited space and a tighter budget—61 keys are sufficient to learn the basics.
Police typically recommend using high-quality deadbolt locks, specifically ANSI Grade 1 or Grade 2 deadbolts, for exterior doors.
A keyway is the unique pattern of grooves and ridges on a key blank or inside a lock cylinder that ensures only the correct key can be inserted. Identifying a keyway accurately allows you to find the exact replacement key blank or select the right tool to pick a lock.
Yes, standard Schlage keys (like the common SC1 profile) can be easily copied at most local hardware stores (such as Home Depot or Lowe's) or by a professional locksmith. The process takes just a few minutes using a key-duplication machine.
No, Schlage keys are not universally interchangeable between all locks. While most residential Schlage locks use the same "C" keyway (often designated SC1 or SC4), which means one key blank can be cut to fit, each lock is typically cut to a unique combination.
To find your Schlage key code (often called a Programming Code for keyless locks), check the yellow or white sticker located in your lock's manual or on the back of the keypad assembly. You can also try a factory reset to restore the original preset codes.
