Quick answer: zero is the number that settles this comparison. That's how many apps, hubs, or WiFi bridges the Kwikset SmartCode 270 needs to keep working through a router outage. The Ultraloq U-Bolt Pro needs 8 AA batteries and an included WiFi bridge, but throws in fingerprint unlock and remote access that the SmartCode 270 simply cannot do.
Bottom Line
Ultraloq U-Bolt Pro
Five ways in: fingerprint, backlit keypad, companion app, Bluetooth auto-unlock, and a physical key. The WiFi bridge ships in the box, so remote access and Alexa or Google Assistant control work without an extra purchase.

A keypad and a key. Nothing else. No WiFi radio to hack, no app account to breach, no firmware to update, and a BHMA Grade 2 certification backing the hardware itself.
See Kwikset SmartCode 270 →That's the short version. The full picture involves unlock redundancy, what happens when the internet drops, battery math, and which lock actually has a documented security grade. Let's get into it.
Head-to-Head Comparison
These two locks solve the same problem, keeping your front door locked, from opposite directions. One assumes you want your phone involved. The other assumes you don't.
| Feature | Ultraloq U-Bolt Pro | Kwikset SmartCode 270 |
|---|---|---|
| Price range | $$ | $ |
| Unlock methods | Fingerprint, keypad, app, Bluetooth, key (5) | Keypad, key (2) |
| WiFi included | Yes, bridge included in box | No radio at all |
| Smartphone app | Yes, remote access and activity log | None |
| Voice assistant | Alexa, Google Assistant (via app) | None |
| Fingerprint unlock | Yes | No |
| Physical key backup | Yes | Yes (SmartKey Re-Key cylinder) |
| Security certification | Not published for this model; check listing | BHMA Grade 2 (confirmed) |
| Weather resistance | IP65 dust and water rated | Check listing |
| Batteries | 8 AA, about 1 year | 4 AA, about 12+ months |
| Keypad code capacity | Check listing | 50 codes (confirmed) |
| Works through internet outages | Local unlock methods keep working; remote features do not | Unaffected, no network to lose |
Price tiers are approximate. $ = under $50, $$ = $50 to 150, $$$ = $150 to 300, $$$$ = over $300. Tap any link for the current Amazon price.
Neither lock is objectively better. The U-Bolt Pro is a connected smart lock with a keypad bolted on as a backup. The SmartCode 270 is a keypad deadbolt that was never designed to connect to anything. Once you frame it that way, picking between them gets a lot easier.
How Owners Rate the Two in Practice
The two locks draw very different kinds of feedback, because they're solving different problems for different buyers.
Ultraloq U-Bolt Pro
Owners consistently highlight how many ways there are to get in the door: fingerprint for the household, a shared code for a dog walker, and the app for everyone else. The recurring praise is that the fingerprint sensor reads reliably even with wet or cold hands, which is the complaint that sinks cheaper biometric locks. The most common gripe centers on setup: getting the WiFi bridge paired to a 2.4GHz network takes some owners longer than expected if their router broadcasts a combined 2.4/5GHz name.
Kwikset SmartCode 270
Owners describe the appeal in almost identical terms every time: it does one job and nothing goes wrong. Buyers switching from app-based locks report relief at not troubleshooting a dropped WiFi connection at 11pm. The SmartKey Re-Key feature draws specific praise from landlords and owners who inherited a house with unknown key copies floating around, since resetting the cylinder takes under a minute with the included tool. The one consistent complaint: without any app, there is no way to see who used which code or when, so shared-access accountability depends entirely on assigning a unique code per person.
Jacob’s read on this category
The real question isn't which lock has more features, it's whether you want your front door on the internet at all. A WiFi-connected deadbolt gives you remote codes and activity logs, but it also means a router outage, a dead bridge, or a forgotten firmware update can complicate your day. A lock with no radio can never be remotely hacked, updated, or bricked by a bad app release, but you also can't let anyone in when you're not home unless they already have a code. Match the lock to how you actually manage access, not to which spec sheet looks longer.
Unlock Methods and Redundancy
Winner: Ultraloq U-Bolt Pro, by a wide margin.
The U-Bolt Pro gives you five independent ways to get inside: a fingerprint scanner, a backlit physical keypad, the companion app over Bluetooth or WiFi, Bluetooth auto-unlock when your phone gets close to the door, and a traditional physical key. If any one method fails, whether that's a dead phone battery, a finger the sensor won't read, or a forgotten code, you have four backups left.
The SmartCode 270 gives you two: the keypad or the physical key. That's the entire list. For a lock this simple, two methods is plenty, since the whole design philosophy is "fewer things that can break." But if you've locked yourself out without the key and can't remember the code, there's no app, no fingerprint, and no remote unlock to fall back on.
Anyone comparing biometric options specifically should also look at our fingerprint smart lock guide, where the U-Bolt Pro shows up again alongside other scanner-equipped deadbolts.
Connectivity, App Control, and Battery Life
Winner: depends entirely on whether you want a network-connected door.
The U-Bolt Pro ships with its WiFi bridge already in the box, which matters because plenty of competing smart locks charge extra for that hardware or sell it as a separate module. Once paired, the app shows lock status, unlock history, and lets you issue remote access from anywhere with a signal. It also connects to Alexa and Google Assistant through that same app, so voice commands and routines are on the table if your smart home already runs on one of those platforms.
The tradeoff is battery draw. Running a WiFi radio takes more power than a lock that never turns one on, and the U-Bolt Pro uses 8 AA batteries to cover roughly a year of typical use. The SmartCode 270 uses only 4 AA batteries and lasts about as long, simply because it never has a radio active in the background.
The SmartCode 270 has no app, no WiFi, and no Bluetooth radio at all. Kwikset built it this way on purpose: no pairing process, no firmware updates, no account to create, and nothing on the lock that can be remotely accessed by anyone, including you, unless they're standing at the keypad. For a rental property or a door where you don't want a persistent smart home dependency, that's a feature. Our guide to smart locks for Airbnb and rental properties covers this exact tradeoff in more depth for landlords weighing WiFi locks against standalone keypads.
Security Certification and Build Quality
Winner: Kwikset SmartCode 270, on paper.
The SmartCode 270 carries a confirmed BHMA Grade 2 residential security rating, the industry's standard scale for measuring a deadbolt's resistance to forced entry, kick-ins, and drilling. That's a documented, third-party-verified number you can point to.
Ultraloq does not publish an ANSI/BHMA grade for the U-Bolt Pro on the current listing, so we're not going to guess one. What the U-Bolt Pro does confirm is an IP65 rating for dust and water resistance, meaning it's built to handle rain, snow, and exposure on an uncovered exterior door without the internals corroding. That's a different kind of durability spec, weatherproofing rather than forced-entry resistance, so it isn't a direct substitute for a published security grade.
If a documented BHMA grade specifically matters for your insurance policy or your own peace of mind, the SmartCode 270 is the only one of these two that gives you a number to cite.

Frequently Asked Questions
Behind This Comparison
These two locks rarely get compared directly because they aren't chasing the same buyer, one is a connected biometric deadbolt, the other is a deliberately offline keypad lock. We cross-checked entry methods, battery specs, and certification claims against each brand's current listing and product pages, and did not carry forward any spec or rating we couldn't confirm for this exact model. Listings were checked on 2026-09-08.
