Quick verdict
A smart-lock keypad is most useful when you want door access by code rather than relying solely on a connected device. The Yale AK-R3 Bluetooth Smart Keypad is a focused choice for homes already using a supported Yale or August Smart Lock: it adds personal entry-code access through a wireless, battery-powered touch keypad with illuminated numbers.
At USD 54.99, this black Yale keypad makes the most sense when compatibility is already established and a dedicated code-entry accessory is the goal. Its appeal is straightforward: no wiring is required, and the package includes the hardware and documentation needed for the keypad itself.
Who it suits
Choose the Yale AK-R3 Bluetooth Smart Keypad if your supported Yale or August Smart Lock would benefit from code-based entry for household members or visitors. The illuminated numeric touch surface is especially relevant for anyone who wants a keypad interface rather than depending on a physical key or another access method.
It is less suitable as a general-purpose door keypad because it is designed for supported Yale and August Smart Locks. The compatibility requirement is the central decision point, not an incidental detail.
What stands out from the listed details
The keypad keeps its feature set practical. Bluetooth connectivity, wireless operation, and battery power support a clean accessory approach without wiring. Illuminated numbers give the touch keypad a clearly defined interface, while the black plastic housing keeps the look consistent with many smart-home door setups.
The package is also notably complete for an open-box item. It includes the Yale Smart Keypad, mounting plate, mounting screws and anchors, removal pin, documentation, and the original retail box. The protective film remains installed on the keypad, while the screws and anchors are sealed.
Meaningful trade-offs
The key trade-off is that this is an open-box unit rather than a sealed retail package. The box has light shelf or storage wear, including minor wrinkling on one corner. For shoppers who place a high priority on untouched retail packaging, that condition may matter more than the included accessories.
The other limitation is scope. This keypad is an accessory for compatible Yale or August locks, not a standalone smart-lock replacement. Its strongest use case is narrow but clear: adding an illuminated code pad to an existing supported lock setup.

Pick this model for its battery-powered, no-wiring design and personal entry-code function with supported Yale or August Smart Locks. The open-box condition and lightly worn retail box are the main compromises, even though the keypad retains its protective film and includes the original accessories.
Bottom line
The Yale AK-R3 is a sensible smart-home accessory when the priority is simple keypad entry for a compatible Yale or August lock. Its illuminated touch controls, battery operation, and included mounting components make the purpose clear; the open-box packaging and compatibility-specific design define the trade-offs.
