Quick verdict
Choosing between these smart home electronics locks starts with a practical tension: do you want a new brass-finish model with Amazon Alexa compatibility named, or a lower-priced satin-nickel model whose Used condition and incomplete wording need to shape the decision?
The Kwikset Home Connect 620 Z-Wave Smart Lock, Lifetime Brass - New is the clearer fit for an Alexa-oriented setup and polished-brass door hardware. The Kwikset Home Connect 620 Z-Wave Smart Entry Door Deadbolt Lock Satin Nickel READ is the better match for silver or satin styling and a lower listed price. Its Used condition and incomplete wording make it a more selective choice.

Where each product wins
Lifetime Brass - New
This model wins when New condition and polished brass are the starting requirements. Amazon Alexa and Z-Wave compatibility are named, making it the more natural fit for a shopper using Alexa. Universal/Reversible door handing is another concrete selection point. The finish is the limitation: Lifetime Brass and Polished Brass do not suit a satin-nickel or silver design brief. Choose it when the new-condition and named-compatibility combination matters more than matching silver-toned hardware.
Satin Nickel READ
This model wins when silver, satin, or nickel styling is the deciding factor, and its lower listed price is central to the choice. It is a smart entry door deadbolt with a Keyless feature and a 1-inch throw length. Those details give a shopper a clear entry profile. The trade-off is condition: it is Used, and the item is marked incomplete with what is missing circled. The READ wording in the title reinforces that this is a more conditional choice than the new brass alternative. It suits a price-and-finish-led decision, not a new-condition priority.
Product notes
Kwikset Home Connect 620 Z-Wave Smart Lock, Lifetime Brass - New
A practical reason to choose this model is its clearly defined hardware set: hardware, instructions, and a key are included. Universal/Reversible door handing is specified, giving an entry-door shopper a concrete fit detail. It is a keyed entry smart door for a front door or front entrance, which places its intended use clearly. The limitation is visual: Lifetime Brass and Polished Brass will not suit someone planning silver or satin-nickel hardware. This makes it a focused choice for shoppers who want the brass configuration and included-item details, rather than a match for a satin finish brief.
Kwikset Home Connect 620 Z-Wave Smart Entry Door Deadbolt Lock Satin Nickel READ
The Satin Nickel READ model gives shoppers a defined one-unit configuration: Model Home Connect 620, Nickel material, and one unit in the pack are specified. That gives the choice a clear identity before condition enters the decision. Its limitation is condition. It is marked Used, and it is also marked incomplete, with what is missing circled. That combination makes it less suitable for someone who wants a new-condition item. It is the more selective pick: useful when finish and the lower listed price lead, but not aligned with a new-item priority.
Final choice by use case
- Choose Kwikset Home Connect 620 Z-Wave Smart Lock, Lifetime Brass - New for a new-condition front-door use case, polished-brass hardware, or an Alexa-oriented setup. Its listed price is USD 60.00.
- Choose Kwikset Home Connect 620 Z-Wave Smart Entry Door Deadbolt Lock Satin Nickel READ when satin-nickel or silver styling and a lower listed price matter most. Its listed price is USD 17.99, but the Used condition and incomplete wording remain central to the decision.
- If neither finish leads, use condition as the tie-breaker: the Lifetime Brass model is New, while the Satin Nickel READ model is Used and marked incomplete.
