$89.99
Product Overview
The Kwikset Convert Zigbee 3.0 Electronic Smart Lock Conversion brings modern smart home functionality to your existing deadbolt without requiring a full door hardware replacement. Designed for homeowners who want enhanced security and convenience, this conversion kit replaces only the interior portion of your current deadbolt while preserving the exterior’s original appearance and mechanical operation. Using advanced Zigbee 3.0 wireless technology, the lock connects seamlessly to popular smart home ecosystems, enabling remote access, real-time monitoring, and voice control integration. Whether you’re at home or away, you can check your front door’s status, lock or unlock it instantly, and receive instant notifications—all through a web-enabled device like your smartphone or tablet. The system supports keyless entry via personalized codes, offers backup key access, and includes a back-lit keypad for reliable use in low-light conditions.
Key Features
- Zigbee 3.0 Wireless Connectivity: Enables secure communication with compatible smart home systems such as Xfinity Home, Samsung SmartThings Hub v3, Amazon Echo Plus, 4th Gen Echo (2020), and Echo Show 10. This ensures stable, long-range connectivity without relying on Wi-Fi, reducing network congestion and improving performance.
- Remote Door Monitoring & Control: Stay connected to your home from anywhere. Check whether your door is locked, send a remote lock or unlock command, and receive instant alerts if someone enters a code or attempts access. Ideal for managing deliveries, granting temporary access to guests, or verifying security while traveling.
- One-Touch Motorized Deadbolt: Features a powerful motor that automatically engages the deadbolt with a single touch from the keypad. This eliminates manual turning and ensures consistent, reliable locking every time—even in cold or wet weather.
- Back-Lit Keypad for Enhanced Visibility: The illuminated numeric keypad lights up when touched, making it easy to enter your code at night or in dimly lit areas. No more fumbling with keys or guessing numbers in the dark.
- Keyless Entry Convenience: Use a personalized access code to unlock the door—no physical keys needed. You can create unique codes for family members, housekeepers, or trusted visitors, and even set temporary or expiring codes for added flexibility.
- SmartKey Security Technology: Includes a rekeyable backup keyway that allows you to easily change the internal pin configuration using standard SmartKey tools. This feature enhances security by letting you rekey the lock if needed, without replacing the entire cylinder.
- Easy Installation & Seamless Integration: Designed specifically to replace only the interior mechanism of your existing single-cylinder deadbolt. This means no changes to your exterior handle or strike plate are required, maintaining the original look and feel of your door while upgrading functionality.
- Battery-Powered Operation: Runs efficiently on four AA batteries, which are standard and widely available. The system provides reliable performance and includes battery life indicators to alert you before power runs low.

Benefits & Use Cases
This smart lock conversion is perfect for homeowners who already have a compatible exterior deadbolt and want to modernize their entry point without a full door overhaul. It’s especially valuable when you’re frequently away from home but still want peace of mind. Need to let in a pet sitter while on vacation? Send them a temporary code remotely. Forgot to lock the door after leaving? A quick tap on your phone locks it instantly. The lock integrates smoothly with home automation routines—such as automatically unlocking when you arrive home based on GPS location or locking up at bedtime via voice command through Alexa.
Guests appreciate the convenience of not needing a physical key, and you retain the option of traditional key access as a backup. The Satin Nickel finish gives the lock a sleek, contemporary look that complements a wide range of door designs. Since only the interior mechanism is replaced, there’s no need to adjust the exterior handle or modify the door frame—making installation straightforward and non-invasive.
Voice control compatibility means you can say, “Alexa, lock the front door” from anywhere in your home, enhancing both security and convenience. The system also supports geofencing, where the lock detects when you’re approaching home and unlocks automatically—ideal for hands-free entry after carrying groceries or during bad weather.
Important Notes
Before purchasing, verify that your current deadbolt meets compatibility requirements. Measure your door’s backset (distance from edge to center of cylinder hole), cross bore diameter (typically 2-1/8 inches), and door thickness (standard is 1-3/8 inches to 2 inches). While the lock is designed to work with most standard single-cylinder deadbolts, some older or specialty models may not be compatible. The conversion does not include drilling tools, so ensure your door has the necessary pre-drilled holes for installation.
While many users report satisfaction with the build quality and ease of use, opinions vary regarding programming complexity and long-term reliability. Firmware updates and full app-based features require a stable internet connection and a compatible hub or gateway. Battery life typically lasts several months under normal usage, but heavy use may reduce longevity. Always keep a physical key handy as a backup in case of power loss or system failure.
Installation is recommended for individuals with basic DIY skills or those willing to hire a professional. The kit includes all necessary mounting hardware, but extra batteries and tools are sold separately. This product is intended for indoor use only and should not be exposed to excessive moisture or extreme temperatures.

- Kwikset Convert Smart Lock Unit (Satin Nickel)

Note: Exterior handle and strike plate must be compatible with standard single-cylinder deadbolts. Not compatible with double-cylinder deadbolts or electronic deadbolts with integrated keypads.
Final Thoughts

Simple Way to Make Existing Locks Smart
This actually replaced my existing Kevo, so it was a simple installation of swapping out this back panel. It paired easily to my Home Assistant via Zigbee. The deviceâs batteries last a lot longer than the August Lock. The back panel is solid, though the black plastic panel is a bit flimsy. Also, the placement of the screw on the bottom makes it challenging to install because the door handle is in the way. Iâd prefer if the unit was more streamlined and less bulky, for a better look. Overall, this is a great alternative to other smart locks and retains the existing lock look and functionality from the front.Works great with Home Assistant.

Great product
Setup was easy. Works with ZHA. I love the fact that there is no need to change the lock mechanism or the outside unit.My favorite part is you can easily remove the battery pack with no tools in two seconds and your lock becomes an ordinary (dumb) lock with no outside connection, and still looks good.

Louder than a chainsaw and dead after 3 months
The instructions are verbose, but fairly usable. Getting it configured “correctly” for left-vs-right doors is confusing at first (mostly a wording and status communication issue) is a bit weird, but fine. Otherwise, it works. Connects just fine to Home Assistant and seems to work.However, it is LOUD. Like… REALLY loud. Like… “power drill” loud. Or “chainsaw”. How is it THIS LOUD? I can literally hear it echoing down the hallway of my floor of the apartment building… from OUTSIDE my apartment.How has no one else mentioned how loud this is? … did I just get a bad unit?Update: 3 months later (note: I replaced the original unit with another that seemed to be slightly quieter), the motor has just stopped functioning. It started sounding a little funny less than a week ago, happily locked yesterday morning when I went to work, but then was no longer working when I got home. No sounds or anything indicating even an attempt to lock/unlock when it is requested to, but it does still seem to be reporting the lock status when manipulated manually. So I guess the motor is just dead. Guess the motor isn’t rated for more than 250-300 cycles…

Cautiously optimistic
Based on the other reviews in withholding final judgment. Right now though I easily installed this device to am existing Kwikset deadbolt. It is connected to my Home Assistant instance via ZHA for a few days now without issue. It responds much faster than the August lock I tried out (likely bc it works without a cloud connection).Couple things though. First it is recognized as a gen 1 when I connected it and the box showed a manufacture date of 2017. Second i was sold an open box unit rather than a new unit. Amazon did give me $20 back so I’m satisfied. The batteries in the box were corroded and weathered by poor storage conditions. The lock hardware itself looks ok. I pulled the zigbee board out and it is in good shape. Even being opened, it was obviously unused so I think it’ll all be ok. Yes it’s loud and you have to take the face plate off to replace batteries but…it ended up only costing $80 so again, I’m ok with some design shortcomings. A few days is not long enough to evaluate battery life but I will update my review if that looks to be an issue.Overall, so long as it lasts, I do not have any major complaints considering the cost.

Works Really Well. Fitment and Orientation are Most Important
It works really well. Locks and unlocks flawlessly with a solid connection to my smart home. The things to watch for most is the orientation of the lock in relation to the deadbolt mechanism (the manuel doesn’t quite make this clear and the lock doesn’t work in the wrong orientation)…Other than that set up is easy it looks nice fits right into the door without really changing anything and without having any weird looking retrofits.

It works
This lock installed fairly easily. I had to enlarge the one insert by filing it a bit to fit my existing lock. So far this has been working properly and I have integrated into the Home Assistant software. The programming was relatively easy with the Zigbee network. My biggest complaint at this time is that it seems to eat batteries. The batteries are at 40% after about a week of only locking and unlocking once a day. This may be due to the factory supplied batteries but some other reviewers relate this issue. I will use a better type of battery when I replace the original ones. The upside is that the app does show what the battery level is.

Discreet and exactly what I needed
Works great with Home Assistant. Doesnât look like an ugly keypad like most. Keeps the original look.Iâve wanted smart locks but the keypad designs are hideous, plus they often have security issues and signal to people that they can try to crack them in some way beyond just kicking the door in.

Wouldnât unlock remotely
I love the way it looks, but it wouldnât work right. It refused to unlock remotely after the first 2 days of use. My hard key worked fine, the device reported lock status fine, it would lock just fine, but it would never unlock using Zigbee. I got a Wyze lock instead which has been working fine for weeks now.

Quite a disappointment, I bought the conversion kit 914 hoping to replace the indoor part of my existing Kwikset 914 lock.It happens there is no cable to connect the outdoor keypad on this kit.Misleading and misrepresentative, you are not buying a 914 model.

If youâre a person who cherishes his/her privacy (especially when it comes to your entrance door usage pattern) you would be using Home Assistant locally with Zigbee (never WIFI or any subscription based cloud service that forces you to download a spyware app on your phone to operate). Then, youâd be interested in this one.Worked very well with ZHA: lock/unlock/battery level.UPDATE:After about 4 months of light use (only 2 people in the household), it starter âskippingâ with a clear audible clicking. It is now a hit-and-miss to unlock it. This makes it is dangerous as you âmayâ be locked out of your home. Now it takes 3-4 times of repeatedly locking and unlocking for a successful unlocking! COMPLETELY unacceptable.The Zigbee ZHA connectivity remains rock solid. No issues there whatsoever.I decided to disassemble it to understand the root cause and to my dismay, I found the mechanism to be predominantly made of cheap plastic susceptible to a high rate of ware and tare. Also the axel that drives the latch to be very wobbly with no support to keep it in place. This leads to easy misalignment and high friction everywhere.I am not sure if the manufacturer decided to save cost in materials or this is just a classic case of âPlanned obsolescenceâ. The end result is the same as this is now unreliable.It is sad that the electronics implementation is âso goodâ. While the hardware is this flimsy. I hope the manufacturer would see this review and gets serious with the hardware side as they do have a potentially magnificent product in hand.Sad, sad, sadâ¦

I tried to install this with a Weiser deadbolt.Issue 1: Kwikset gave 3 separate kits for Weiser/Baldwin/Schlage locks, but the connector did not match the suggested kit for Weiser. The one for Schlage looked correct.Issue 2: However, the provided screws did not fit the existing deadbolt, so I used the existing bolts.Issue 3: The learning process seemed to have issues adjusting to the existing deadbolt and never finished with a green light (success).Issue 4: Since this was from a non-Amazon seller, I have to pay for shipping and take the 20% restocking hit. Lesson learned.
