Kwikset 83735 Kwikset 660 Deadbolt Cylinder, Exterior, 5-Pin

The 83735 is a SmartKey Security cylinder, so it re-keys with the SmartKey tool and an existing working key rather than by disassembling the lock and swapping pins. That is the main reason to pick this part over a standard pin cylinder: a landlord or property manager can re-key an exterior deadbolt at tenant turnover in under a minute without pulling the cylinder. It runs the Kwikset KW1 keyway, so it takes standard KW1 blanks.

KW1 is the keyway, which is the same keyway used across Kwikset's residential line, so the 83735 accepts the same key blanks as the rest of a Kwikset-keyed building. Two ways to get them on one key: order it Keyed Alike, or use the SmartKey feature to re-key the cylinder to a key you already carry. If you want it on a separate key, order Keyed Different. Keying selection is required when you order.

No. The 83735 is a single cylinder part, the exterior key cylinder for a Kwikset 660 deadbolt. The inside of a 660 is a thumbturn, not a second keyed cylinder. If you are servicing a double cylinder deadbolt (keyed on both faces, typically used next to glass), this is only the outside half and you would need the interior keyed cylinder separately.

It is a residential-rated part. The 83735 is built for the Kwikset 660 residential deadbolt, so it belongs on apartment entry doors, single-family homes, and light multi-family openings. For a storefront, a school corridor, or anything spec'd to a commercial grade, a residential SmartKey cylinder is the wrong part, look at a commercial mortise or rim cylinder in the keyway your facility is already keyed to.

That is exactly what the 83735 is: the exterior key cylinder for the Kwikset 660 deadbolt, sold on its own. If the bolt still throws cleanly and the problem is a worn, jammed, or compromised key cylinder, you replace this piece rather than the full deadbolt and keep the existing bolt, strike, and door prep. It is a keyed mechanical cylinder, no electronics involved.

Two: Venetian Bronze and Polished Brass. Match the finish to the deadbolt collar and rose already on the door, a replacement cylinder sits in plain view on the exterior face, so a mismatched finish shows. If the rest of your building is on a satin nickel or matte black trim package, neither of these two will blend.

Pick Keyed Alike at the order, and if you are matching cylinders to a key system you already run, enter the key code in the optional key code field so the new cylinders come cut to it. Keying is a required selection on the 83735, there is no default, so a bulk order for a building gets set once and arrives on one key. Leave it Keyed Different when each door needs its own key.

The 83735 is the 5-pin exterior deadbolt cylinder. Pin count is a keying question, not a fit question: a 5-pin cylinder is cut on a 5-position KW1 key. If your building is already running Kwikset KW1 keys, the blank is the same either way, but confirm your existing key bitting depth positions before ordering keyed to code.
