Hello everyone,
We have a multi-family house, but only relatives live there. I want to switch to smart door locks and am considering whether to choose Nuki Ultra or Bold. The main differences are:
Nuki Smart Ultra:
Bold Elite SX33:
Prices are relatively similar for the complete package. There isn’t much difference. We have 1 main entrance door, 4 apartment doors, and 1 garage door.
1. First question: What is the name of the latch on the strike plate that allows the door to be opened without a key by simply pushing harder? (The latch basically doesn’t hold against the strike plate)
2. Second question: What are the strike plates called that have a latch allowing the door to be opened without a key by pushing harder? Are these also available for apartment doors? The strike plate height is 20cm (8 inches).
Use case: Children come home from school at midday. On the main entrance door strike plate, we have the latch “unlocked” so the children can enter anytime without a key or smartphone. At our apartment door, they have to knock or ring the bell.
With Nuki, the following would be possible:
With Bold, I don’t see this option. But you could give the children a clicker. If they lose it, you can simply deactivate it. This isn’t as problematic as losing a key.
3. What are your thoughts? All other common use cases should be similar. Which would you tend to choose? Does anyone have experience with either system?
We have a multi-family house, but only relatives live there. I want to switch to smart door locks and am considering whether to choose Nuki Ultra or Bold. The main differences are:
Nuki Smart Ultra:
- It actually turns the key, so it can open and close both the latch and the deadbolt
- If someone doesn’t have a smartphone, they can still lock and unlock with the traditional key
- Battery lasts about 6 months
Bold Elite SX33:
- The exterior knob is free-spinning. By activating it via smartphone or a clicker, the knob is engaged and you can lock or unlock. This extends battery life significantly
- If someone doesn’t have a smartphone, they can lock and unlock with the clicker
- Battery lasts about 2 years (and apparently even longer depending on use)

With Nuki, the following would be possible:
- You unlock the latch on both the main entrance and apartment doors. The children could enter anytime. Via the app, you could lock both doors by engaging the deadbolt into the strike plate again. Then a key or clicker would be needed. So at certain times the children could just enter freely.
With Bold, I don’t see this option. But you could give the children a clicker. If they lose it, you can simply deactivate it. This isn’t as problematic as losing a key.

iOS or Android?Android. Yes, that’s not really a dealbreaker. The only issue is the volume, especially in the evening when the apartment is generally quiet.Nuki was delivered yesterday.
Today I tried to install it – but without success. The cylinder is 10 mm (0.4 inches) too long. The included mounting plates for the Nuki lock do not have a through-hole for the cylinder, which limits the maximum length. I assume this is for added stability, but it also restricts the choice of cylinders that can be used. There is no extra space either.
Now I have to get a 45/45 cylinder, as currently a 45/55 cylinder is installed.
Visually, it makes a very high-quality impression.

One of the two mounted plates. There are also versions with offset screw holes.

I also initially considered it because of the children. However, I find it too insecure this way. And the older child definitely won’t get a smartphone in elementary school.

I initially thought about it because of the kids. But for me, it’s just too insecure. And the older child definitely won’t get a smartphone in elementary school. Well, look at that—are burglary gangs already using fingerprints now? What nonsense. Just as pointless as switchable power outlets so the burglar can’t use their drill.
You watch too much Mission Impossible. Be careful the thieves don’t start wearing masks soon and sneak into your house pretending to be your wife.
