Yale Assure Lock 2 Wi-Fi
Yale Assure Lock 2 Wi-FiGRADE 2 · 4 AA · ~1 YR

Fit ledger — need → measured evidence

FITS YOUR DOOR
Covers 1-3/8 in to 2-1/4 in doors on a 2-3/8 in or 2-3/4 in backset and a 2-1/8 in bore — a taller thickness ceiling than the Schlages, which stop at 1-3/4 in.
SECURITY GRADE
ANSI/BHMA Grade 2 with a keyed backup cylinder on this YRD410 variant, so a flat battery is a key turn rather than a locksmith call.
BATTERY REALITY
About a year on four AA even with the Wi-Fi module fitted — unusual, because Wi-Fi locks normally drain cells 2-3x faster than Bluetooth or Thread models.
NO HUB, NO FEE
Built-in Wi-Fi means no bridge and no subscription — remote unlock, guest codes and event history are free in the Yale Access app, as on all twelve locks compared.
RUNNING COST
Reckon $8-$25 a year in AA cells and nothing else; the only add-on Yale sells for it is the Matter module, and that is bought separately.
AUTO-UNLOCK TRUTH
Its auto-unlock is Bluetooth geofence — the feature most owners switch off because it fires from the driveway. UWB is the actual fix, and the cheapest UWB lock here is $270.

  The catch — co-equal billing, always

This SKU has no Apple Home Key, and Wi-Fi and Matter share one slot. Home Key needs the key-free touchscreen Assure Lock 2 Plus, not this pushbutton YRD410-WF1 — and because the Wi-Fi module and the Matter module occupy the same bay, fitting Matter-over-Thread means giving up built-in Wi-Fi. You get one radio or the other, never both.

Why the Yale Assure Lock 2 Wi-Fi is right for you

It avoids every trap below — and for anyone, under $250, it is the pick because it delivers:

Trap 01

Fit returns more locks than anything else

Measure before you order, not after. Most picks here fit 1-3/8 in to 1-3/4 in doors on a 2-3/8 in or 2-3/4 in backset and a 2-1/8 in bore. The Level Lock Pro needs 1-3/4 in to 2 in, so it is simply wrong for a standard 1-3/8 in door — and no lock on this card fits a mortise lock or a euro cylinder.

Trap 02

"Retrofit" usually is not one

Only the Yale Approach keeps your existing exterior hardware and keys. The Aqara U400 and the Level Lock Pro replace the entire deadbolt despite being routinely described as retrofits — that is a modification to the door, and your lease or HOA may forbid it.

Trap 03

A grade and a keyway are not implied

BHMA AAA / ANSI Grade 1 covers the Encode Plus, Arrive, Halo Select and eufy E34; the Yale Assure Lock 2 and Wyze Bolt v2 are Grade 2; Lockly, Aqara and the Yale Approach publish no grade at all. And the Schlage Sense Pro has no keyway — flat AA cells plus a missed low-battery alert leaves you outside.
