Kwikset KWI-4345 Plug Clip

The 4345 is the small retaining clip that holds the plug assembly together while you work a Kwikset cylinder, part of the rekeying and installation accessory hardware rather than a lock component you'd install in a door. If you've pulled a Kwikset plug to swap pins and the clip is bent, lost, or fatigued, this is the replacement piece that gets the cylinder back together.

The Kwikset 4345 plug clip is a residential Kwikset accessory, so it will not serve a Schlage cylinder. For Schlage residential rekeying, the Schlage Commercial 40-133 Home Secure Keying Kit is the corresponding item, supplied as a part/component for that job. If the work is over the counter on Schlage cylinders generally, the Schlage Commercial 40-132 Retail Keying Kit is the pinning kit for that.

No. The Kwikset 4345 is a plug clip, an installation accessory that goes with residential Kwikset rekeying work. The Schlage Commercial 40-132 Retail Keying Kit is a pinning kit, meaning it is the pin-and-key kit used to key a Schlage cylinder rather than a single clip component. A locksmith holding a Kwikset cylinder wants the 4345 clip; someone setting up to key Schlage cylinders wants the 40-132 kit. They are different brands' cylinder platforms and the parts are not interchangeable.

Just the clip. The 4345 is a single installation accessory, not a pinning kit, so it carries no pins, springs, or key blanks. If you need a complete pinning setup, that's a different purchase, for example a Schlage Commercial 40-132 or 40-133 keying kit on the commercial side.

The 4345 is a per-cylinder part, so plan on one clip for each Kwikset plug you're servicing where the original clip is damaged or missing. On a fleet rekey most original clips survive reuse, so the usual pattern is ordering a handful as spares rather than one for every door.

The Kwikset 4345 plug clip is an installation accessory used while handling a cylinder plug, not a measuring tool. To decode cuts on a key, the Schlage Commercial 40-104 Pin Tumbler Key Gauge is the item built for that purpose. A property manager auditing keys on a building and a locksmith rebuilding a cylinder are buying two different things here.

The Kwikset 4345 is a single plug clip, a residential installation accessory. The Schlage Commercial 40-074 Everest Vice Jaw Upgrade Kit is a pinning kit in the Schlage parts and accessories series, upgrading a bench setup to handle Everest cylinders. One is a consumable component that goes into the lock; the other is bench tooling for a specific Schlage keyway platform. Ordering the 40-074 will not give you a clip for a Kwikset plug.

Yes, in practice. The 4345 plug clip is a Kwikset residential accessory and pairs with Kwikset cylinders. Standardizing instead on Schlage means stocking Schlage's own keying items, such as the 40-132 Retail Keying Kit or the 40-133 Home Secure Keying Kit, and for Everest keyway work the 40-074 Everest Vice Jaw Upgrade Kit. Deciding the platform first keeps you from stocking clips and kits from two systems that do not cross over.

No, the 4345 is a plug clip, a physical retaining part for the cylinder. A key gauge is a separate bench tool for reading pin depths off a key, like the Schlage Commercial 40-104 Pin Tumbler Key Gauge. Don't substitute one for the other.

One version only. The Kwikset plug clip is sold as model 4345, with no size, finish, or handing options to specify, so ordering is straightforward once you've confirmed you're working on a residential Kwikset cylinder.
