Yale Assure Lock Fits 2-1/8 Inch Backset

The title specifies an extended range WiFi connection, which is critical if your apartment's router is on a different floor or behind thick concrete walls that typically block standard smart lock signals. This Black Suede finish is designed to replace a standard deadbolt mechanism while maintaining that specific connectivity advantage.

In the product photo, verify that the exterior keypad is fully visible and not obscured by the door edge, as this model relies on the keypad for keyless entry. Check the internal thumbturn area to ensure it is a standard lever or thumbturn compatible with a 2-1/8 inch backset, avoiding any proprietary mounting plates that would require new drilling.

This listing highlights the Google Nest integration and a tamper-proof design, which is a specific security feature for keyless entry on a front door. The Black Suede finish is consistent with the premium tier of Yale's lineup, but the key detail here is the explicit mention of the keypad deadbolt format.

Look closely at the photo of the lock's side profile to confirm the depth of the mechanism. You need to see a standard deadbolt body that fits within your existing 2-1/8 inch backset hole, rather than a thicker smart lock body that would protrude or require a larger bore hole in your apartment door frame.

The title explicitly calls this a retrofit smart lock, which is the exact terminology for a device designed to work with your existing door hardware without replacing the entire lock cylinder. The Silver finish is a neutral choice, but the 'Unlimited Virtual Keys' feature is the functional differentiator for apartment living where you might share access with roommates or guests.

In the listing image, focus on the internal mounting plate. It should show a standard screw pattern that aligns with a 2-1/8 inch backset. If the photo shows a unique, wide mounting bracket, it will not fit your existing door frame without drilling new holes, which is the primary failure point for retrofit kits.

This product is defined by its inclusion of a Kincaid BK lever, which means it is a lever-style lock rather than a traditional deadbolt. The title also lists compatibility with the Yale Access App, Amazon Alexa, and Google Assistant, indicating a broad smart home ecosystem integration.

Check the photo to see if the lever mechanism is a standard 2-1/8 inch backset lever. Many lever locks have a different internal geometry than deadbolts, so you must confirm the internal plate fits your existing hole. If the photo shows a deadbolt thumbturn instead of a lever, this specific ASIN is not the correct fit for a lever-based apartment door.

The title identifies this as a push-button keyless lock in Polished Brass, which suggests a specific aesthetic and interaction model that differs from keypad-based systems. The 'Connected' designation implies it requires a hub or direct WiFi connection, which is a critical detail for apartment buildings with strict network policies.

In the product photo, look for the internal mounting hardware. This type of push-button lock often has a different internal depth than a standard deadbolt. Verify that the internal mechanism fits within your 2-1/8 inch backset without requiring a longer screw or a different hole pattern, as this is a common point of failure for non-standard smart locks.

This listing specifies a Bluetooth connection rather than WiFi, which means it will likely require a bridge or hub to function with your smart home system. The keypad feature is highlighted for keyless entry, but the Bluetooth protocol is the key technical detail that affects how you will manage access from your phone.

Examine the photo of the lock's exterior to ensure the keypad is not too large for your door's edge. More importantly, check the internal view to confirm the deadbolt body is a standard size that fits a 2-1/8 inch backset. Bluetooth locks sometimes have larger internal batteries that can interfere with the door's existing latch mechanism if the backset is not precise.

Similar to the other extended range models, this title emphasizes the WiFi capability and keyless entry features. The Black Suede finish is a visual marker, but the 'Extended Range' claim is the functional promise that the signal will reach your phone even if you are in a different part of the apartment.

In the product photo, verify the alignment of the internal thumbturn with the door's strike plate. A 2-1/8 inch backset lock must have the thumbturn centered in the door's thickness. If the photo shows the thumbturn offset or the internal plate extending beyond the door edge, it will not fit your existing frame without modification.

This listing includes a Norwood lever, which is a specific brand of lever mechanism that may have different mounting requirements than a generic lever. The title also reiterates compatibility with the Yale Access App and major smart home assistants, ensuring broad integration options for your apartment's smart setup.

Look at the photo to confirm the lever's internal mounting plate size. Norwood levers can have unique screw patterns that do not align with a standard 2-1/8 inch backset. If the photo shows a non-standard plate, you will need to drill new holes, which defeats the purpose of a no-drill replacement. Ensure the lever's internal mechanism fits within your existing door hole.
