Overview

What it is and where it fits

The eufy FamiLock S3 Max is a US-style smart deadbolt with a palm reader, a 2K doorbell camera and a 4-inch screen on the inside. It suits a Dubai owner whose door is already drilled for an American deadbolt. Most local doors are not, so we check yours first. You hold your palm near the outside unit and it reads the vein pattern under the skin, which works with wet, dusty or worn hands. There is also a keypad, the eufy Security app, voice control and a backup key. The camera doubles as a video doorbell, and clips save to 16GB of storage inside the lock, so no subscription is needed. Anyone inside can check the door on the screen without a phone. It runs on a 15,000mAh rechargeable battery with four AAA cells as a backup, and it connects straight to 2.4GHz Wi-Fi, so there is no hub to buy. The fit is the catch. This lock needs a round 54 mm hole through the face of the door, 60 or 70 mm in from the edge, on a door 35 to 55 mm thick. Typical Dubai villa and apartment doors use a European mortise lock instead, a rectangular lock case set into the door edge with a lever handle. On those doors the S3 Max means drilling a new hole, which is permanent and not allowed on fire-rated tower doors. It is also large and heavy on the door. If your door has a mortise lock, a mortise video lock is usually the better choice.

  • 2K doorbell camera with clips saved on the lock, no monthly fee
  • Inside screen shows who is at the door without a phone
  • Matter support for Apple Home, Google Home, Alexa and SmartThings

What to check before you order

This is an American deadbolt, and that decides everything in Dubai. A US door is drilled with a round 54 mm hole through its face for the lock. Most villa and apartment doors here use a European mortise lock, a rectangular case slotted into the door edge, so that hole does not exist. We inspect the door before we sell or fit this lock. It suits doors already prepared for US hardware, new solid timber doors that can be drilled to suit, and villa side or annex doors you own that are 35 to 55 mm thick. Many large villa main doors are thicker than 55 mm. Tower apartment entrance doors are usually fire-rated, and drilling them breaks the rating, so building management will normally refuse. Tenants need written landlord approval, and a new hole cannot be undone. For sun-facing villa doors, add shade. Wi-Fi must be 2.4GHz and strong at the door, and dust on the camera lens needs a regular wipe.

Answers

Questions about the eufy FamiLock S3 Max Video Smart Lock with Palm Vein Recognition

What is the eufy FamiLock S3 Max?
Chevron down icon
It is a smart deadbolt that combines three things: a palm vein reader, a 2K video doorbell camera and a 4-inch screen on the inside of the door. It also has a keypad, app control and a physical key. It replaces an American-style deadbolt, not a European mortise lock.

How much does the eufy FamiLock S3 Max cost in the UAE?
Chevron down icon
When we checked on 13 September 2026 it was AED 1,198.80 on Amazon.ae, sold by AnkerDirect AE and in stock. eufy's own UAE store listed it higher at AED 1,399. Prices move with sales, so check the day you buy. Fitting is quoted separately after we see the door.

Will the S3 Max fit my Dubai front door?
Chevron down icon
Probably not without changes. It needs a door drilled for a US deadbolt, with a round 54 mm hole through the face. Most Dubai villa and apartment doors use a European mortise lock and do not have that hole. Send us photos of both sides and the door edge, or book a visit, and we will confirm.
Contact us
Contact us
What is a US bore, and why does it matter for this lock?
Chevron down icon
A US bore is a round hole about 54 mm wide drilled straight through the door, plus a smaller hole from the door edge for the bolt. American doors come drilled this way. The S3 Max is built to sit in that hole. Without it, there is nothing for the lock to mount into.

My door has a lever handle with a key cylinder under it. Can I use the S3 Max?
Chevron down icon
That layout is a European mortise lock, the most common type in Dubai. The S3 Max cannot replace it. The only route is drilling a new 54 mm hole above the existing lock and keeping your lever for the latch. That is permanent, needs solid timber, and is not allowed on fire-rated doors.

Which doors in the UAE does the S3 Max suit?
Chevron down icon
It suits doors already prepared for American hardware, new solid timber doors that can be drilled for it, and secondary villa doors such as a side, garden or annex door that you own. The door must be 35 to 55 mm thick and not fire-rated. For mortise doors we recommend a mortise lock instead.

Can I fit the S3 Max on an apartment door in a Dubai tower?
Chevron down icon
Usually no. Apartment entrance doors in towers are normally fire-rated, and drilling a new hole through one breaks that rating. Building management and the fire safety rules for the building will not allow it. On a tower apartment, a retrofit lock that clips over the inside thumbturn is the safer option.
Contact us
Contact us
I rent my home. Can I install the S3 Max?
Chevron down icon
Only with written approval from your landlord. Fitting this lock on a typical Dubai door means drilling a hole that cannot be reversed, so you cannot hand the door back as you found it. Most tenants are better served by a retrofit lock such as the SwitchBot Lock Ultra, which leaves the door unchanged.

Do I need a HomeBase or hub for the S3 Max?
Chevron down icon
No. The lock connects straight to your home Wi-Fi and records to its own 16GB of storage. You can add a eufy HomeBase 3 if you run other eufy cameras and want them managed together. eufy states the S3 Max does not work with the older HomeBase 2.
Contact us
Contact us
Is there a monthly subscription?
Chevron down icon
No subscription is needed. Video clips are saved on the 16GB of storage inside the lock, and live view, alerts and remote control all work through the free eufy Security app. eufy sells optional cloud backup if you want copies stored off the lock, but you can ignore it.
Contact us

Does the S3 Max work with Apple Home, Alexa and Google Home?
Chevron down icon
Yes, through Matter. You can add the lock to Apple Home, Google Home, Alexa or SmartThings to lock it, open it and check its status. The camera feed does not pass through Matter, so video, palm settings and clips stay in the eufy Security app.

What happens during a DEWA power cut or if the internet drops?
Chevron down icon
The lock keeps working because it runs on its own battery, not mains power. Palm, keypad and the physical key still open the door. What you lose without Wi-Fi is remote control, phone alerts and live view from outside the house until the router comes back.

How long does the battery last in Dubai heat?
Chevron down icon
eufy quotes several months per charge on the 15,000mAh battery, with the four AAA cells as a backup for when it runs flat. Real life is shorter with heavy camera use, busy doors and strong heat, which is hard on any lithium battery. Plan to recharge every few months and keep the app alerts on.
Contact us
Contact us
Can it handle a sun-facing villa door in a 45 degree summer?
Chevron down icon
The outside unit is rated from -30 to 70 C and carries an IP65 rating, so heat and dust are within spec. A dark lock in direct afternoon sun still gets very hot on the surface. Where a door faces west with no canopy, we suggest shade to protect the battery and screen.

How does the palm vein reader work?
Chevron down icon
You hold your open palm in front of the reader and it uses infrared light to map the veins under your skin. Because it reads under the surface, wet, sweaty, sandy or worn hands still work. It stores up to 50 palms, and data stays on the lock rather than in the cloud.

Does the S3 Max have a fingerprint reader?
Chevron down icon
No. The S3 Max uses palm vein recognition instead of fingerprints. If your household prefers fingerprint entry, the eufy E330 has a fingerprint reader and a doorbell camera, though it is also a US deadbolt design with the same door fit limits in Dubai.

How do I give my maid, driver or cleaner access?
Chevron down icon
Give them their own keypad PIN or register their palm, so each entry shows in the app log under their name. You can remove their access from your phone at any time without changing keys. This is easier to manage than handing out copies of a physical key.

Is the S3 Max a good lock for a holiday home?
Chevron down icon
It can work for a DTCM holiday home if the door suits it. You can send guests a PIN from the app, see arrivals on camera and check the lock status remotely. The door fit is still the deciding factor, and most holiday apartments sit in towers with fire-rated doors.
Contact us
Contact us
What does the screen on the inside do?
Chevron down icon
The 4-inch screen on the inside unit shows a live picture from the outside camera. Children, older family members or house staff can see who is at the door without opening it or picking up a phone. The Amazon.ae listing we price includes the screen in the box.
Contact us
Contact us
How secure is the eufy S3 Max?
Chevron down icon
The deadbolt carries an ANSI/BHMA Grade 1 rating, the highest US grade for this type of lock. Palm data is stored on the lock itself. As with any smart lock, use a strong app password and turn on two-step login. Physical strength still depends on the door and frame.
Contact us
Contact us
Does it work on 5GHz Wi-Fi?
Chevron down icon
No, it needs a 2.4GHz Wi-Fi network. Most home routers broadcast both bands, so this is rarely a problem. Signal at the door matters more. Villa entrances often sit behind thick block walls, so we test the signal at the door and add a mesh point if needed.
Contact us
Contact us
How long does installation take, and can you fit it?
Chevron down icon
On a door already drilled for a US deadbolt, fitting and app setup take about one to two hours. Where a door needs new preparation, it takes longer and we agree it with you first. Yes, our technicians supply and fit it after checking the door.

How does the S3 Max compare with the eufy E330?
Chevron down icon
Both are eufy video deadbolts for US door preparation, so the Dubai fit issue is identical. The S3 Max adds palm vein reading, a 2K camera and an inside screen. The E330 uses a fingerprint reader, has no inside screen and costs less. Choose on features only once the door suits either.

Should I pick the S3 Max or a mortise lock like the Yale YDM4109A?
Chevron down icon
If your door has a European mortise lock, which is most Dubai doors, the Yale YDM4109A or an EZVIZ DL50FVS video lock fits it without drilling a new hole. The S3 Max only makes sense on a door already prepared for US hardware or one you are happy to have drilled.
Contact us
Contact us
Who should not buy the eufy S3 Max?
Chevron down icon
Skip it if you rent, live in a tower with a fire-rated entrance door, have a standard mortise lock you want to keep, or have a door thicker than 55 mm. Also skip it if you want a slim lock, because both halves are large and heavy on the door.
Contact us
Contact us
What maintenance does the S3 Max need?
Chevron down icon
Recharge the main battery when the app warns you, and replace the AAA backup cells if they have been used. Wipe dust off the camera lens and palm reader, especially after a sandstorm. Keep the app and firmware updated, and test the physical key every few months.

What about warranty and support in the UAE?
Chevron down icon
Buy from AnkerDirect AE on Amazon.ae or eufy's UAE store so the warranty goes through the brand's regional channel, and keep your invoice. Check the warranty term on the listing before ordering. When we fit the lock, we handle installation issues directly.
