Kwikset 660 Deadbolt Lock Review

Our Summary

The Kwikset 660 (96600-869) is for exterior doors that need a keyed single-cylinder deadbolt with SmartKey re-keying.

The listing says the deadbolt locks with a key outside and a turn piece inside, and that the SmartKey feature lets you re-key it yourself in seconds. It fits doors 1-3/8 to 1-3/4 inches thick and the latch backset adjusts to 2-3/8 or 2-3/4 inches with a twist. It installs with a screwdriver and comes with the hardware and directions. The listing says security, durability and finish are BHMA Grade 3, and that a lifetime mechanical and finish warranty applies. The color is satin nickel. The weight is about 1.1 pounds. The model is 96600-869.

Grade 3 is the lowest of the three BHMA grades, so consider a higher grade for a door that needs more security. A deadbolt is only as strong as the door, the frame and the strike plate, so use the long screws that reach the stud. Do not leave the key in the lock, and keep a spare. Check the door prep matches (a 2-1/8 inch bore and a 1 inch edge bore). The page does not say how many keys come in the pack. Read the warranty for terms.

Best-Fit Shopper

This style of doors & windows suits shoppers who already know they need deadbolts coverage and want a Kwikset option with transparent listing details.

It is a weaker match if you need a fully custom install, a different capacity class, or a feature the hub row simply does not list.

What to Double-Check

Trade-offs are normal in deadbolts. A design that wins on portability may give up enclosed storage; a long wireless claim may assume open line-of-sight; a high load rating usually assumes even distribution.

Our Hardware Pick badge is editorial shorthand for “worth considering in this category,” not a guarantee for every floor plan, campsite, or property layout.

Alternatives Context

Against generic no-name alternatives, Kwikset listings often win on clearer packaging and easier returns through Amazon — still read the live seller and fulfillment line.

Against premium ecosystems, this unit may look simpler. That can be a feature if you want fewer apps and more straightforward hardware.

Final Buying Notes

Buy the Kwikset 660 Deadbolt Lock if the hub numbers and feature set line up with your deadbolts job. Skip it if you need a capability the listing does not document.
