Yale Assure Lock 2 Plus

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. A bare price under this product name means nothing without the configuration attached. Never treated as a live price.)

Compatibility

Protocols: WIFI · BLUETOOTH · NFC^[1][3]

What it can do^[8]

Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.

Subscription reality^[2]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

Maintenance reality^[4]

• Batteries: AA x4 — expect roughly 18 months per set
• Works without the internet: Not established — we have not sourced this yet. 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).

Security updates^[10]

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's parent publishes per-model security-support declarations, and this US lock is not among them. Yale UK maintains a PSTI documentation library of 27 signed Statements of Compliance, 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 document 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 declaration that names a sibling never transfers. On the US side, the shopyalehome.com product page states no support period, and Yale's US support portal could not be read at all: it returns a client-rendered shell of a few dozen characters to a plain fetch, so it is named here as unread rather than counted as silence.

The catch

No Matter and no Thread — ecosystem reach rides Yale's Wi-Fi cloud; 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; works for Alexa/Google/SmartThings on the Wi-Fi model.
