Fit My Door Lock product guide
Yale Assure Lock 2 Keypad with Wi-Fi, Black Suede (YRD410-WF1-BSP)
Standard US doors that pass Yale's printed door checker
A keypad deadbolt with a removable Wi-Fi module, unlimited scheduled codes, Auto-Unlock and a DoorSense sensor that keeps Auto-Lock from throwing the bolt on an open door. It keeps a mechanical key. Two things to settle first: the Wi-Fi band, and whether your door passes Yale's own Door Checker.

Fit and limits

Caveats

- Electronics warranty is stated as one year on Amazon, two on Yale's page
- Door thickness and bore limits in the listing differ from the guide
Check your door before you buy, not after
Yale ships a tear-off Door Checker in the installation guide, and it is blunt about failure: for several measurements it simply says your door is not a match for a Yale smart lock. The checks are door thickness, backset, face bore diameter, edge bore diameter and depth, strike pocket diameter and depth, and clearance above the existing knob or lever.
Door thickness is handled by three screw sets: a blue set for one and three eighths inch doors, a black set for one and three eighths to one and three quarter inch doors, and a silver set for two to two and a quarter inch doors. Backset can be two and three eighths inches out of the box or two and three quarters after adjusting the latch. Face bore can be two and one eighth inches, or one and a half inches if you unscrew the black adapter from the lock.
The listing's own description gives different numbers from the guide it attaches. It says the lock fits doors one and three quarters to two and a quarter inches thick with a two and one eighth inch bore and a four inch minimum centre-to-centre spacing between deadbolt and knob. The guide says one and three eighths to two and a quarter inches, allows a one and a half inch bore, and asks for two inches of clearance between the top of the existing knob trim and the centre of the deadbolt hole. Measure against the guide.
Yale says 2.4GHz only; the listing says 2.4 or 5
This one is worth settling before you order. The Amazon bullets and description say the lock connects directly to 2.4 or 5 GHz Wi-Fi without a hub or bridge. The footnote on Yale's own product page for this SKU says Wi-Fi models require a 2.4GHz Wi-Fi network. Those are different requirements and we are not going to pick one for you.
It matters because the Wi-Fi module has to join whatever network you actually run at home. Check whether your router lets you connect a device to a 2.4GHz network on its own, and ask Yale to confirm in writing which requirement applies to the module in the box.
The Wi-Fi capability itself comes from a removable Yale Smart Module that this bundle includes. Yale's page notes Bluetooth is included on all Assure Lock 2 products while the Wi-Fi module upgrade is what adds remote access and the extra voice and smart-home integrations. The installation guide warns that batteries must not be installed when you insert or remove that module.
Every way in, and what happens when the batteries die
You unlock by pressing the Yale logo to wake the keypad, entering a code and pressing the checkmark. Other routes are the Yale Access app on a phone or Apple Watch, a voice assistant, Auto-Unlock that opens the door as you approach, the inside thumbturn, and a mechanical key cylinder. This is the keyed version, so the key override is present.
Entry codes are four to eight digits, unlimited in number, and can be permanent, recurring or on a temporary schedule. The guide notes a code must be entered within five seconds while the keypad is active, and the same code cannot be used for two different users. After five wrong codes the lock shuts down for sixty seconds, and both the attempt limit and the lockout time are adjustable in the app.
Power is four AA alkaline batteries with three escalating low-battery warning levels. Yale's page says a battery-powered lock still works in a power cut, and the guide's troubleshooting is equally direct about the other case: if the lock does not respond and the door is locked, use the mechanical key. Nothing we read describes an external emergency power contact.
DoorSense, Auto-Lock and the modes you should know about
DoorSense is the door-position sensor that lets the lock tell open from merely unlocked. It mounts two ways: surface-mount with a screwdriver and adhesive tape, or flush-mount, which needs a five eighths inch drill bit and a half inch deep hole in the door frame. Yale asks for it within one and a half inches of the frame edge, aligned with the lock, and calibrated in the app afterwards.
Auto-Lock is off by default and can run on a timer from thirty seconds to thirty minutes. With DoorSense fitted, the guide says the door will not lock until it is actually closed, which is the behaviour that stops a deadbolt throwing into an open frame. A passage button inside temporarily suspends Auto-Lock.
Two other modes are worth knowing. Vacation operating mode restricts all entry-code access while leaving app control working. Verified Access, off by default, requires biometric or passcode authentication in the app before the lock will operate. A separate programming code, generated by the app, is used for handing, module setup and diagnostics and cannot unlock the door.
Installation, and the parts that decide whether it goes well
This is a full deadbolt replacement, so the guide's first step is to remove your existing deadbolt, and it suggests keeping the old one until the new lock is working. Yale says the job needs a standard Phillips screwdriver, with drill, chisel, knife, tape measure, level and pencil only if you have to adjust or prepare the door.
The box holds the exterior keypad, interior lock, mounting plate, adjustable deadbolt latch, strike plate, battery cover, reset pin, DoorSense with housing, cover, tape and flush-mount cap, the three screw sets, optional security strike screws, batteries and keys. Note a discrepancy: Amazon's included-components field mentions one key, while the guide's In The Box illustration shows two.
The guide's troubleshooting section is about alignment. The guide's hardware troubleshooting covers a grinding deadbolt that needs re-handing through the settings menu, a deadbolt hitting the strike plate, a strike pocket that is not deep enough, and resistance that means bending the tab on your existing knob or lever strike plate. It also warns that failure to follow the instructions could void the factory warranty.
Integrations, certification wording and two warranty answers
Yale's page lists the smart-home partners for this model as Google Home, Amazon Alexa, Apple HomeKit, ecobee Smart Security, Philips Hue, Samsung SmartThings and Airbnb, with voice through Alexa, Google and Siri. For Apple Home remote access it says you need an Apple TV, iPad or HomePod set up as a hub, and the Yale Access app is limited to the US and Canada per the listing.
On certification, the Amazon bullets say the lock is Grade 2 certified by BHMA and rate it for minus 22 to 140 degrees Fahrenheit. Neither Yale's own product page nor the installation guide states a BHMA grade or a temperature range in anything we read, and no certificate was read, so treat both as listing claims and ask Yale if either is decisive for you.
The warranty answers do not match either. Amazon's warranty field says a lifetime limited warranty on finish and mechanical parts with one year on electronics. Yale's own page for this SKU shows a two-year electronics warranty badge alongside 30-day returns. Get the current terms from Yale in writing before you rely on either figure.
