Compiled by SmartHomeWorkflow Research · Yale · Smart Locks · ~$309.99 ($309.99 for the Wi-Fi configuration this record describes (YRD450-N-WF1, 'Assure Lock 2 Plus with Wi-Fi and Apple Home Keys'), read from Yale's own store structured offer data on 2026-08-08. ⚠ THE NAME COVERS THREE CONFIGURATIONS AT TWO PRICES: the Bluetooth-only 'with Apple Home Keys' (YRD450-N-BLE) is $219.99, and a 'Wi-Fi Connect for Vacation Rental Hosts' variant (YRD450-N-CB1) is also $309.99.

How to read the equipment roles
This shows the connection route, not every network cable or a shopping list. One device may provide several roles, including a Matter controller and a Thread border router. Only a Thread connection needs the Thread role. Read the equipment cards for all recorded requirements.
These paths summarize documented setup options. Check the function table for the connection covered by each recorded capability.

Officially supported in HA core two ways, both with real setup caveats: the August/Yale-Access cloud integration lists the Assure Lock 2 (the lock must be online — built-in Wi-Fi WF1 model or a Connect bridge), and the local Yale Access Bluetooth (yalexs_ble) integration lists the YRD450 but requires extracting the Yale Access offline key. HA's docs name the base YRD450/Assure Lock 2 family, not the Home-Key '-N Plus' variant specifically.[5][28][29]
One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

Batteries: AA x4 — manufacturer-stated 18 months per set
Works without the internet: Inconclusive — we read the vendor's own material and it does not answer this either way. It does not mean the product fails without the internet.
Longest-lived battery of our locks — 4xAA alkaline rated ~18 months (Yale). Fully KEY-FREE: no physical keyway. Dead-battery backup is the exterior 9V terminal — hold a 9V battery to the two contact pads under the keypad to power it up long enough to enter your code. Low-battery: on-screen + app notice at 25%, then daily email/push as it drains. Ecosystem features ride Yale's Wi-Fi cloud (Yale Access), so a Yale-cloud outage degrades remote/voice control (the Apple Home Key tap itself is local NFC).
Yale publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.
Yale publishes product-by-product security-support promises, and this US lock is not among them. Yale UK keeps a library of 27 signed compliance statements under the UK's product security law (PSTI), each covering one product and each stating a defined support period; the Linus L2 statement (YE00007SLK, signed by Richard Bromley, VP CTO and Head of Residential, Willenhall, 28th March 2024) declares "4 Years from 1st January 2024". Every statement in that library covers a UK product line: Linus L1 and L2, Conexis L2, Connect X, Keyless Smart Lock, the Yale Smart and Sync alarms, the UK camera and CCTV kits. None names the Assure Lock 2 Plus or its model number YRD450-N-WF1, and a promise made for a sibling product never carries over. On the US side, the shopyalehome.com product page states no support period, and Yale's US support site could not be read at all (it shows almost no text without a full browser), so it counts as unchecked rather than as saying nothing.
The catch
No Matter and no Thread — Yale says the Wi-Fi model is what carries the voice and smart home integrations; key-free, so the only physical fallback is the exterior 9V emergency terminal. And check which box you are buying: Yale sells a Bluetooth-only 'Assure Lock 2 Plus with Apple Home Keys' for $219.99 that looks identical and has no Wi-Fi radio, so Alexa, Google, SmartThings and remote access do not apply to it. The compatibility on this page is the $309.99 Wi-Fi model.
Who it's for
Apple households wanting Home Key tap-to-unlock with the longest battery life here; Yale names Alexa, Google Home and SmartThings for the Wi-Fi model, without saying what each can do with the lock.

[3] Replaces a prior fabricated 'Yale Assure Lock 3 Ultra' catalog row that had NO Yale primary source (only third-party 'best of 2026' guides). Yale's Z-Wave-module page excludes the Plus (YRD450-N) from the swappable module bay, and every Plus page confirms Home Key + Wi-Fi with no Matter/Thread; Matter is a separate Yale SKU (Smart Lock with Matter, YRD510) that has no Home Key.

Wi-Fi bands it can use
shopyalehome.com/pages/yale-assure-lock-2, product banner + its footnote (as of 2026-09-10): 'Now, with 5GHz Wi-Fi' — '5GHz Wi-Fi support is only available for Yale Assure Lock 2 models with a Wi-Fi module', which this model is
shopyalehome.com/pages/yale-assure-lock-2, compatibility footnote and FAQ answer (as of 2026-09-10): 'Wi-Fi models require a 2.4GHz Wi-Fi network' and 'You'll need the lock to be connected to a home 2.4GHz Wi-Fi network'
We publish: unknown
Both sentences are Yale's, on one page, and both claim to cover a Wi-Fi-module model. Picking the newer banner would assert 5 GHz on a lock whose own FAQ says to connect it to 2.4 GHz; picking the FAQ would ignore a specification Yale advertises. Neither is a reading of the evidence — it is a choice between two of Yale's statements, which is the maker's to reconcile, not ours.
