SwitchBot's Lock Ultra Max Vision Pro Combo, announced at IFA Berlin on 3 September 2026, is a retrofit smart lock bundle for European doors that opened for UK pre-orders the same day at £339.99. The combo packs three parts: the new Lock Ultra Max (a faster brushless-motor version of the Lock Ultra), the Keypad Vision Pro (3D face, palm-vein, fingerprint, PIN and NFC entry), and a Hub Mini Matter Enabled that bridges the lock into Apple Home and Home Assistant. For UK buyers it is the first SwitchBot lock explicitly listed as fitting UK oval cylinders and night latches without changing the cylinder, and it undercuts comparable Nuki bundles. The caveat is that this is a pre-order announcement: the launch-window Max Service promotion runs only to 30 September, shipping dates are not yet published, and the Lock Ultra Max is not yet named in Home Assistant's SwitchBot Bluetooth integration docs, so early Home Assistant control will run over Matter via the hub.
What is in the Lock Ultra Max Vision Pro Combo?
The combo bundles a Lock Ultra Max, a Keypad Vision Pro and a Hub Mini Matter Enabled into a single £339.99 kit, and SwitchBot also lists the Lock Ultra Max alone at £189.99 on its UK store. The lock is the headline upgrade. SwitchBot says its UltraDrive brushless motor spins at up to 160 rpm, roughly three times the previous Lock Ultra, and can turn a euro or oval cylinder in as little as 1.1 seconds in Fast Mode, with a Quiet Mode rated at around 56 dBA for early mornings. Power comes from a 4,200 mAh rechargeable pack that SwitchBot rates at up to nine months, a CR123A backup that takes over automatically for roughly 500 operations, and a supercapacitor that stores enough residual charge for a handful of emergency unlocks if both run down. The body is aluminium alloy with a brushed, fluted finish, measuring 122 × 62.6 × 66.8 mm and weighing 391 g with batteries.
Does the SwitchBot Lock Ultra Max fit UK doors?
Yes, according to SwitchBot's UK product listing, which names EU profile, UK oval, Swiss round and night-latch mechanisms as supported, with extra adapters for unusual installs. That matters more in the UK than the "99% of European locks" figure in the press release, because most UK composite and uPVC doors use a euro cylinder while many older timber doors use a rim night latch, and previous retrofit locks have often handled one but not the other. The lock mounts over your existing thumbturn, so the cylinder, keys and insurance-rated hardware stay in place. If you are not sure what you have, our smart lock installation guide walks through identifying door and cylinder types before you buy. Note that a night latch install still leaves the deadlock unmanaged, so anyone who habitually double-locks a mortice will need to think about how that fits an auto-lock routine.
How does the Keypad Vision Pro unlock the door?
The Keypad Vision Pro adds five hands-free or contactless entry methods on the outside of the door: 3D facial recognition using more than 30,000 infrared points, contactless palm-vein scanning, fingerprint, passcode and NFC card. SwitchBot quotes face recognition inside 0.6 to 0.9 m and palm-vein inside 8 to 25 cm, with a false-acceptance rate it puts below 0.0001%, and says all biometric templates are stored on the keypad rather than in the cloud, with AES-128 encryption between keypad and lock. Its 5,000 mAh battery is rated at up to 12 months. Counting app, Apple Watch, voice, widgets, geofenced auto-unlock, SwitchBot Remote, home sharing and the physical key, SwitchBot arrives at "19 ways to unlock", though in daily use most households will settle on two or three. The earlier Keypad Vision reviewed well for face recognition but was found to be sensitive to ambient lighting, so expect placement to matter.
Does the Lock Ultra Max work with Home Assistant?
It does, but through Matter rather than Bluetooth at launch. The bundled Hub Mini Matter Enabled exposes the lock as a bridged Matter device, and Home Assistant's Matter integration supports bridges from SwitchBot alongside door-lock control, so you get a lock entity, lock and unlock actions and state for automations once the hub is commissioned. What you do not get over a bridged SwitchBot lock, based on how the current Lock Ultra behaves, is much beyond a single lock entity: door-open state, battery level and keypad credential management stay in the SwitchBot app. The direct Bluetooth SwitchBot integration currently lists the Lock, Lock Pro, Lock Ultra and Lock Lite, which expose battery, door status and auto-lock state locally without a hub; the Ultra Max is not yet listed, so treat Bluetooth support as likely but unconfirmed. If you want Home Assistant to manage PIN codes centrally, read how the Matter Lock Manager works, and check which credential types a given bridge passes through before relying on it.

Is the SwitchBot combo worth pre-ordering in the UK?
It is a strong option if you want palm or face entry on a UK oval or night-latch door without replacing the cylinder, but there is no penalty for waiting a few weeks for hands-on reviews beyond losing the launch bonus. Pre-orders through SwitchBot's UK site placed between 3 and 30 September 2026 include a free year of Max Service, which SwitchBot values at £24.90 and which adds a year of warranty on top of the standard two years plus faster replacement handling. Against the field in our best smart locks for UK homes round-up, the closest rival is Nuki's keypad-and-bridge bundle, which the SwitchBot combo undercuts while adding biometrics, though Nuki has a longer track record on European doors. Prices vary by retailer and pre-order terms can change, so check the listing before committing. One SwitchBot-specific point worth checking on arrival is the full shipping date, which was not published at announcement.
