## Best For

- Existing 4th-generation Pro owners adding Matter
- Discount buyers who verify the exact generation
- Homes with Thread border router coverage near a compatible European door

## Skip If

- The listing says Smart Lock 3.0 Pro
- The newer Smart Lock Pro (5th Gen) is close in price
- You want the smaller Ultra lock body

## Setup Notes

- Confirm the lock is the 4th-generation Pro, not Smart Lock 3.0 Pro.
- Use the Nuki app for setup, firmware, calibration, and accessory pairing.
- Pair through Matter over Thread only after the lock is working reliably in Nuki.

## Known Limitations

- The newer Pro and Ultra models may be better buys at similar prices.
- Matter apps may expose fewer lock-administration features than Nuki's app.
- Door compatibility still controls the recommendation.

## Pros

- Direct Matter-over-Thread support in the older Pro body
- Includes Pro-level Nuki features compared with the regular 4th-generation lock
- Can use Remote Access via Thread in Nuki's 4th-generation path

## Cons

- Superseded by the 5th-generation Smart Lock Pro
- Requires compatible European door hardware
- Matter still needs a Thread border router

## Check the generation before the deal

Nuki Smart Lock Pro (4th generation) is a valid direct Matter-over-Thread lock, but the generation label matters. Smart Lock 3.0 Pro is not the same buyer story.

That makes this page most useful for existing owners, used listings, and discounted inventory. If you are shopping new, compare the 5th-generation Pro first.

## Matter is the shared control layer

The 4th-generation Pro can join Matter ecosystems over Thread, so you do not need a Nuki bridge for that path. You still need a Matter controller with Thread border router support, and you still need the Nuki app for setup, calibration, firmware, and accessory details.

As with other Matter locks, test the platform-specific behavior before relying on routines, shared access, or detailed notifications.

## When to move on

Skip this model if the price is not meaningfully better than the 5th-generation Pro or if the listing does not make the generation clear. The Matter label is useful, but it does not erase the normal used-lock risks around batteries, fit, and missing accessories.
