Schlage vs Kwikset: Which Lock Brand Is Higher Quality?

Schlage and Kwikset are the two most common residential lock brands in North America, and locksmiths get asked about them constantly. In short: Schlage is generally considered the higher-quality lock, while Kwikset is usually more affordable and very easy to rekey. Here is how they compare.

Quick Answer

Schlage locks tend to be more durable, offer better security features and are built with stronger materials. Kwikset is often less expensive and easier to rekey, which makes it popular with builders and property managers. If security and long-term reliability are your priority, most locksmiths lean toward Schlage.

Build Quality and Durability

Schlage is known for heavier construction and robust internal parts, which is why its locks hold up well on high-use doors. Kwikset uses lighter materials and simpler mechanisms in many of its residential lines, which keeps the price down but can mean more wear over time on a busy entry door.

Security

Schlage locks are widely regarded as offering better resistance to picking and bumping than entry-level Kwikset models. Whatever brand you choose, look for a solid deadbolt, proper installation with long strike screws, and a reputable keyway.

Keyways: SC1 vs KW1

Schlage residential locks most commonly use the SC1 keyway (5-pin), while Kwikset uses the KW1 keyway (typically 5-pin). The two keys are not interchangeable, so a Schlage key will not operate a Kwikset lock and vice versa. Locksmiths stock both blanks because they are among the most-duplicated keys in the country - see our residential key blanks.

Rekeying Schlage and Kwikset Locks

Both brands can be rekeyed with a pinning kit: remove the cylinder, swap the pins to match a new key, and reassemble. Kwikset's design makes this especially quick, and Kwikset SmartKey models can be rekeyed without removing the cylinder. For professional work, a brand-specific kit such as the Kwikset and Schlage re-keying combo kit covers both.

Replacement Cylinders

If a cylinder is worn or damaged, you can often replace just the cylinder instead of the whole lockset. For Schlage-type hardware, a Schlage SC1/SC4 key-in-knob, lever and deadbolt cylinder is a common replacement.

Which Should You Choose?

• Choose Schlage for front entry doors, high-traffic doors and when security is the priority.
• Choose Kwikset when budget matters, for interior doors, or when you expect to rekey often (rentals, new construction).
