This Bosch FU6 Plus review covers what you're actually paying for: a dual-battery power supply (4200mAh plus a 2250mAh backup) so a drained battery doesn't strand you outside your own door. The Bosch FU6 Plus is a fully automated smart lock that also supports facial recognition, fingerprint, PIN, card, and app access, and it costs AED 2,750. It's not a budget pick — it's the model to choose when battery redundancy matters more to you than price.
Full feature set
The FU6 Plus covers every common unlock method in one lock:
- Facial recognition for hands-free entry
- Fingerprint storage for household members
- PIN code entry, with expiry you set yourself when you generate a code
- IC card access
- App control over WiFi, for remote unlock and activity notifications
- Built-in intercom with remote talk, so you can see and speak to whoever's at the door before letting them in
- Dual battery (4200mAh + 2250mAh) as backup power
- Mechanical backup key, included as standard on every Bosch and SmartLuck model
Fingerprint, PIN, and card access all work without WiFi — the app and remote notifications are the only features that need a network connection.
What the dual-battery setup actually solves
Every smart lock on the market runs on a battery, and every smart lock warns you before it runs low. The FU6 Plus goes a step further by building a second battery into the lock itself, rather than relying on you to notice a warning and act on it in time. If you travel often, if the lock is on a door you don't pass every day, or if you've simply been caught out by a dead lock battery before, this is the model built specifically for you.
It's worth being precise about what this means: even on models without a second battery, a dead battery doesn't lock you out — every Bosch and SmartLuck lock can be jump-started with a power bank through its emergency power port, or opened with the mechanical backup key. The FU6 Plus doesn't solve a lockout risk the others don't already cover; it reduces how often you'd ever need that fallback in the first place.
Bosch FU6 Plus review: where it sits in the lineup
Bosch prices the FU6 Plus above both the Bosch FU8 (AED 2,650) and the Bosch FU30 Plus (AED 2,450) — the two models SmartLuck positions as its "camera tier" for facial-recognition buyers on a mid-range budget. That makes the FU6 Plus the more expensive option of the three, not the cheaper one, so don't go in expecting a discount pick with a nice extra feature. You're paying specifically for the second battery.
If your priority is the lowest price with fingerprint and app access, the Bosch ID30 at AED 1,450 is the better fit — it's the model SmartLuck installs most often in Dubai apartments, though it doesn't include facial recognition or an intercom. If you want facial recognition and a guest-code intercom system without paying for the second battery, the Bosch FU8 covers the same core feature set as the FU6 Plus at a lower price, minus the dual-battery redundancy.
Installation and warranty
Like every Bosch and SmartLuck model, the FU6 Plus requires professional installation — it's not a clip-on retrofit over an existing lock body. SmartLuck installs it free of charge in Dubai and Sharjah (charges apply in other Emirates), and a technician tests facial recognition, fingerprint, PIN, and card setup with you before finishing the job. It carries a 12-month warranty as standard, the same coverage as every other model in the lineup regardless of price tier.
Who should (and shouldn't) buy the FU6 Plus
Buy it if dead-battery anxiety is the specific problem you're solving — a door you don't use daily, frequent travel, or a household that's been locked out by a flat battery before. Skip it if you're optimizing for price (the ID30 is AED 1,300 cheaper) or if you want the same facial-recognition and intercom feature set without paying for the extra battery (the FU8 gets you there for less).
FAQ
What makes the Bosch FU6 Plus different from other Bosch smart locks?
Its dual-battery design — a 4200mAh main battery plus a 2250mAh backup — built directly into the lock. Every Bosch model already prevents a true lockout through a power-bank jump port and a mechanical backup key, but the FU6 Plus reduces how often you'd ever need to reach for that fallback, since the second battery takes over before the first one runs out.
Is the Bosch FU6 Plus a budget option?
No. At AED 2,750, it's priced above both the Bosch FU8 and Bosch FU30 Plus, which cover similar facial-recognition and app features for less. The FU6 Plus is a reliability pick for buyers who specifically want backup power redundancy, not an entry-level model.
Does the Bosch FU6 Plus work without WiFi?
Yes, for the core unlock methods. Facial recognition, fingerprint, PIN, and card access all work with no internet connection at all. WiFi is only needed for remote app control and push notifications, so a router outage never blocks you from getting through your own door.
Can I set a temporary guest code on the Bosch FU6 Plus?
Yes. You can generate a PIN code and set its own expiry at the moment you create it, so a cleaner, driver, or short-term guest gets access only for as long as you intend, with no permanent key to hand out or collect back.
Is the Bosch FU6 Plus suitable for a villa main door?
Yes, with one caveat: if the main door is fully exposed to direct sun and rain with no porch or overhang, Bosch models like the FU6 Plus are the right call over SmartLuck-branded alternatives, specifically for weatherproofing and build quality on that kind of exposed installation.
