Top complaints

Yale Approach Lock with Wi-Fi + Keypad

  • Needs a plug-in Wi-Fi bridge

    Without the included Yale Connect bridge it works only over Bluetooth. The bridge takes up an outlet and is larger than most smart plugs (Wirecutter, Tom's Guide). Tom's Guide says Wi-Fi would be better built into the lock, as on the August.

  • No Apple Home

    Wirecutter and Tom's Guide both note it doesn't support Apple Home. Tom's Guide says Matter support was promised by software update.

  • Noisy motor

    Tom's Guide lists a noisy motor as a reason to avoid it, in both its review and its buying guide.

August Wi-Fi Smart Lock (4th Gen)

  • Short battery life

    PCMag says its two CR123 batteries are expected to last up to three months, so keep spares, and lists short battery life as a con. Amazon's summary says owners report replacing them about every six weeks.

  • Auto-unlock and Wi-Fi misfires

    Amazon's summary says feedback on auto-unlock and Wi-Fi is mixed, with some owners reporting random unlocking at night and frequent disconnections. Wirecutter warns that geofenced auto-unlock risks accidental unlocking on any lock.

  • Bulky and pricey

    Tom's Guide calls it 'quite bulky' and prefers the slimmer Yale Approach. CNET says it is still bulky and lacks full Matter support. PCMag lists it as pricey, and some Amazon owners say it isn't worth the price.
