By way of its official eufy Amazon storefront, Anker is offering returning low prices on three of its popular smart locks – all with palm vein recognition. Things start with the base FamiLock E34 Smart Lock at $179.98 shipped, matching the direct website pricing, while the more advanced FamiLock S3 Smart Lock is down at $229.48 shipped (matching its direct pricing), and the most advanced FamiLock S3 Max Smart Lock at $279.98 shipped (matching its direct pricing). These three models usually go for $280, $350, and $400 at full price, respectively, which we last saw drop to these all-time low prices back during Christmas sales, while we also saw some shorter-term dips to these rates in early January. Now, you’re getting the first shot to grab them at their best prices in 2026, saving you $100 or $120 off the going rates.
Ready for quick installations without alterations or drilling new holes, these Anker eufy FamiLock smart locks are designed to “fit standard US and Canada doors.” They come boasting multiple ways to enter your home, with the standout being the palm vein recognition, though you also have the options for a traditional key, a PIN code, in-app unlocking, or with voice commands through Alexa or Google Assistant. They even come Matter-equipped for greater integration across the most popular ecosystems: Apple Home, SmartThings, and more. They can run for up to eight months at a time, thanks to the 10,000mAh battery and separate non-removable 750mAh backup battery that keep things wireless.
Where things start to change is with the two more advanced upgraded models that offer all the same features above, and more. There’s the FamiLock S3 model that brings along a 2K HD camera so you can gain video feeds to any device with the companion app, while the FamiLock S3 Max offers the same on top of an integrated display for video footage you don’t have to open the app for.
That’s not all we’ve spotted from this brand for your security upgrades either, as the solar-powered Security SoloCam S340 2-Cam Kit and 4-Cam Kit (both with HomeBase 3) are starting from a $350 low right now too. For inside your home, especially if you have kids or pets, there’s also the ongoing deal for the Anker eufy S350 Security Indoor Cam at $100, which brings along dual 4K and 2K cameras, 8x zoom, 360-degree pan/tilt, and AI tracking.
