The short answer: for most renters, the better retrofit lock is the one that fits your cylinder and connects the way you want without extra hardware — and once you count the hub, the winner flips. The Nuki Smart Lock (Deadbolt) is $159 with built-in Wi-Fi, so remote access costs nothing extra. The SwitchBot Lock Pro (W3500000) looks cheaper at $119.99, but remote access needs a Hub 2 at $69.99, taking the real total to $189.98 — about $31 more than the Nuki. Check cylinder compatibility first, hub needs second, and only then compare price. Prices checked 6 Nov 2026 on the makers’ US stores; Amazon street prices may differ, so check the live price before you buy.
Most retrofit lock comparisons fail renters the same way: they compare features, then the buyer discovers the lock does not fit their cylinder, or remote access needs a hub they did not buy. Fit and connection are the purchase; everything else is secondary.
Quick comparison: Nuki vs SwitchBot retrofit locks
| Factor | Nuki | SwitchBot |
|---|---|---|
| Retrofit idea | Fits over the existing cylinder, keys kept | Fits over the existing lock, keys kept |
| Remote access | Built-in Wi-Fi — connects directly to your home Wi-Fi, no hub needed (Matter needs a compatible hub) | Needs Hub 2 (sold separately) for remote access and Matter |
| Cylinder compatibility | US model fits single-cylinder deadbolts — check your cylinder type on the listing | Check your lock type on the listing |
| Renter-friendliness | No cylinder change, original keys kept | No lock change, original keys kept |
| Price, checked 6 Nov 2026* | $159 (lock alone, Nuki US store) | $119.99 lock alone + $69.99 Hub 2 = $189.98 for remote access (SwitchBot US store) |

Total cost to get remote access — the maths that decides it
Lock-only prices mislead. Remote access is the feature most renters actually buy the lock for, so the honest comparison is the total cost to get it:
| Nuki Smart Lock (Deadbolt) | SwitchBot Lock Pro | |
|---|---|---|
| Lock alone | $159 | $119.99 |
| Hub needed for remote access | None — built-in Wi-Fi | Hub 2, $69.99 |
| Total for remote access | $159 | $189.98 |
The Nuki ends up about $31 cheaper once the hub is counted, even though the SwitchBot lock alone looks $39 cheaper. The cheaper route into SwitchBot remote access is the Lock Pro + Hub Mini (Matter) bundle at $149.99 — still $9 less than the Nuki, but that is the Hub Mini, not the full Hub 2 with its sensors and smart buttons, so compare like with like. If you already own a Hub 2, or you only need Bluetooth access at the door, the SwitchBot maths changes — the hub is only a cost if you actually need it.
What actually matters in a retrofit lock?
Cylinder compatibility first. Retrofit locks fit specific cylinder and lock types. Photograph your lock, check the manufacturer’s compatibility list, and do not assume a lock that fits a neighbour’s door fits yours.
Hub or Wi-Fi second. This is where the two differ most. A model with built-in Wi-Fi connects directly; a model that needs a hub needs that hub bought, plugged in, and placed within range. Add the hub to the price before you compare, and check whether the hub is included in the box you are buying.
Renter rules third. Retrofit means no cylinder change and no new keys for the landlord in most cases, which is why renters choose these locks. Keep the original hardware and keys for move-out, and check your lease if it mentions locks at all.
App and access fourth. Who gets a code, who gets a key, and how you revoke access matter more over a year than the lock’s headline features. Check guest codes, auto-lock, and what happens if the batteries die or the Wi-Fi drops.
1. Nuki Smart Lock (Deadbolt) — best if you want Wi-Fi without a separate hub
Nuki’s appeal for renters is straightforward: the US model, the Nuki Smart Lock (Deadbolt), has built-in Wi-Fi, so remote access does not need extra hardware in the hallway — it connects directly to your home Wi-Fi and you manage it from the Nuki app. At $159 (lock alone, Nuki US store, checked 6 Nov 2026) it is also the cheaper total once remote access is counted. One caveat from Nuki’s own page: Matter integration needs a compatible hub, so if Matter is the reason you are buying, check that separately. And the fit check still comes first — the US deadbolt version fits single-cylinder deadbolts, not European cylinders.
2. SwitchBot Lock Pro (W3500000) — best if the hub cost still wins
SwitchBot wins on the lock price alone — $119.99 for the Lock Pro (SwitchBot US store, checked 6 Nov 2026) against the Nuki’s $159 — and loses some of that advantage once a Hub 2 ($69.99) is added for remote access, taking the real total to $189.98. If you already own the hub, or you only need Bluetooth access at the door, that maths changes — the hub is only a cost if you actually need it. The cheaper bundle worth knowing about is the Lock Pro + Hub Mini (Matter) at $149.99, which covers remote access and Matter for $9 less than the Nuki, though without the Hub 2’s sensors and buttons.
3. Cylinder compatibility — the check that decides it
Neither lock wins if it does not fit your door. Check cylinder type, lock type, and door thickness on the manufacturer’s compatibility page before you buy either. This check takes five minutes and prevents the most common retrofit return. For a broader overview, see our guide to the best smart lock for renters without changing hardware.
4. Batteries and failure modes — best for peace of mind
Both locks run on batteries, and both need a plan for dead batteries and lost Wi-Fi. Check battery type, battery life on the listing, and whether the original key still works — for a retrofit lock, the key should always remain your backup.
5. Guest access — best for hosts and sharers
If you share the home, host guests, or let a cleaner in, guest codes and time-limited access matter. Check how codes are created and revoked in each app, and whether revocation works without Wi-Fi at the door. If you host, see our guide to an affordable smart lock setup for a small rental portfolio.
What to check before you buy Nuki or SwitchBot
Does it fit your cylinder? Check the manufacturer’s compatibility list with a photo of your lock. Do not guess from a product photo.
Does remote access need a hub? Add the hub to the price if it does, and confirm whether the box you are buying includes it.
Do you keep your original keys? For a retrofit lock, yes — and keep the original hardware for move-out.
What happens when batteries die or Wi-Fi drops? The original key should still work. If it does not, that lock is not a retrofit lock in the sense renters need.
Frequently asked questions
Which is better for renters, Nuki or SwitchBot?
The one that fits your cylinder and connects the way you want. Nuki can win on built-in Wi-Fi; SwitchBot can win on lock price if you already have, or do not need, its hub.
Do I need a hub for a retrofit smart lock?
It depends on the exact model. Some models have built-in Wi-Fi; others need a hub for remote access. Check the model, not the brand.
Can my landlord object to a retrofit lock?
Retrofit locks do not change the cylinder or the keys, which is why renters choose them — but check your lease and keep the original hardware.
What happens if the smart lock battery dies?
Your original key should still open the door. Check battery type and life on the listing, and replace batteries before they run flat.
Is Nuki available in the US?
Yes — Nuki launched a US deadbolt version in July 2025 (single-cylinder deadbolts): the Nuki Smart Lock (Deadbolt), $159 on Nuki’s US store (checked 6 Nov 2026). Check the US listing, not the European Pro listing — the Smart Lock Ultra (Euro Profile) is a different model for European cylinders only. Keep the cylinder check first — US deadbolt vs European cylinder are different models.
