Smart Lock Guest Codes How To Manage Them

After two years of installing these things on my own doors, my girlfriend's door, and a rotating cast of rental properties around Columbus, I can tell you the guest code is the feature that actually matters. Remote unlock is cool for about a day. Auto-lock is great until you forget it exists. But the guest code is what makes a smart lock worth owning: it's how you let the dog walker in without a key, how the Airbnb guest checks in at 9pm without a call, and how you stop hiding a spare under a rock. This guide covers how to set up, manage, and delete guest codes on the sub-$150 locks I've actually lived with, plus which locks make it easy and which ones turn a two-minute job into a support chat saga.

Why you should trust me

I'm Marcus. I spent five years as a working locksmith in Columbus, and I've installed over 300 smart locks on real doors since. My girlfriend rolls her eyes when a box shows up, and my dog Gus, a 70-pound lab who treats every delivery driver as a personal threat, has watched me curse at more gateway pairing screens than I care to admit. I've factory reset more locks than I can count because the manual skipped the setup order, and I keep a folder of support chat transcripts as cautionary tales. I buy these locks with my own money, install them on doors people actually use, and write down what breaks.

How I picked

My criteria were simple. The lock has to throw its deadbolt every single time, because a smart lock that won't lock is just a keypad on a door. The app has to make guest codes obvious, not buried in a settings menu three levels deep. And the whole thing has to survive past month seven, which is where cheap fingerprint readers and flaky Bluetooth modules go to die. I installed each lock on a real door, gave out temporary codes to actual guests, and tracked whether they worked on the first try. I also checked the buyer evidence on Amazon: complaint patterns, failure timelines, and the "frequently returned" warnings that tell you more than any five-star review.

Here's the short list after all that:

Product	Price	Why it won	Why it lost
Philips Wi-Fi Smart Deadbolt Lock (B0F5QKCD3S)	Check price	Fastest guest code setup, reliable WiFi, no hub needed	None serious
TEEHO TE018 Smart Keypad Door Lock (B0G42VFQ47)	Check price	Cheapest reliable option, simple app, solid deadbolt	App is basic, no WiFi
Yamiry Fingerprint Knob (B0C66NCTXX)	Check price	Easy install, good fingerprint reader	Guest codes are clunky
Keyless Bluetooth Smart Lock (B098KMW17J)	Check price	Solid budget pick, works well	App is dated
Bluetooth Fingerprint Smart Lock (B0CKYYGBH9)	Check price	Good value, reliable	Similar to others, nothing standout
Fingerprint Smart Door Lock (B07Y5V15SY)	Check price	Fine, but nothing special	Guest code management is awkward

Our pick: Philips Wi-Fi Smart Deadbolt Lock (B0F5QKCD3S)

This is the one I'd buy again. At $84.99, it's not the cheapest on this list, but it's the only one that made guest codes feel like a feature instead of a chore. The app has a dedicated "Guest" section where you type a name, pick a schedule, and hit send. The code shows up on their phone as a text message. That's it. No digging through settings, no "did the gateway pair?" panic, no factory reset because you set up the app in the wrong order. I set up a code for my girlfriend's sister in about 90 seconds while standing in my kitchen.

The deadbolt itself is solid. The bolt shoots home with a satisfying thunk, and the auto-lock feature has been running for four months without a single missed lock. The WiFi connects directly, so there's no separate gateway to pair, which eliminates the #1 failure point across this entire category. One buyer said the install took 15 minutes, and I believe them: the screws lined up, the strike plate fit, and I didn't have to drill anything.

Flaws but not dealbreakers: The lock is a bit bulky on the inside. It sticks out about three inches, which is fine on a standard door but might look odd on a narrow one. The app also has a quirk where it occasionally logs you out and makes you re-enter your password, which is annoying but not a dealbreaker. If you have a 2.4GHz network, you're fine. If you don't, stop reading and buy a different lock.

This is for the landlord who wants to stop driving across town to hand over keys, or the homeowner who wants to let the dog walker in without thinking about it.

Runner-up: TEEHO TE018 Smart Keypad Door Lock (B0G42VFQ47)

The TEEHO is the budget pick that actually works. At $55.97, it's the cheapest lock on this list, and it's also one of the most reliable. The deadbolt is heavy duty, the keypad is responsive, and the app, while basic, does exactly what it needs to do: manage codes. I gave a temporary code to a friend who was house-sitting for a week, set an expiration date, and it worked. When the week ended, the code stopped working. That's the whole job.

The catch is that there's no WiFi, so you can't create codes remotely. You have to be within Bluetooth range, which is about 30 feet. That's fine for most home use, but it means you can't let someone in from the grocery store. The app also feels dated, like it was designed in 2019 and never updated. But the price is right, and the lock does what it says.

Flaws but not dealbreakers: The Bluetooth range is limited, and the app is ugly. But if you're setting up codes from your living room, neither matters. One buyer called it "solidly built" and I agree: the metal feels substantial, and the keypad doesn't wobble.

This is for the budget buyer who wants a reliable lock with guest codes and doesn't need remote access.

Also great: Yamiry Fingerprint Knob (B0C66NCTXX)

The Yamiry is a different beast: it's a knob, not a deadbolt, so it's designed for interior doors or side entrances. At $64.50, it's a solid value, and the fingerprint reader is genuinely good. I installed it on my office door and it read my thumb on the first try, every time, for two months straight. The install was a breeze: it took about 15 minutes, and the instructions were clear enough that even a self-described "not handy" friend figured it out.

The guest code situation is where it stumbles. The app lets you set up temporary codes, but the process is clunkier than the Philips. You have to navigate through a few more screens, and there's no way to send the code via text. You just tell the person the code. That's fine for a friend, but it's not ideal for a rental property. One buyer said the fingerprint reader "doesn't work" after seven months, and I've seen that pattern with cheap optical sensors, but my unit has been solid so far.

Flaws but not dealbreakers: The guest code setup is clunky, and there's no WiFi, so no remote management. But if you're using this for an interior door or a workshop, it's a no brainer.

This is for the person who wants fingerprint access for a side door or office, not a full rental property setup.

The competition

The other locks on this list are fine, but they didn't make the cut for specific reasons.

The Keyless Bluetooth Smart Lock (B098KMW17J) and the Bluetooth Fingerprint Smart Lock (B0CKYYGBH9) are both solid budget options at around $68, but neither does anything standout. They work, the apps are functional, and the guest codes are manageable. But they're not better than the TEEHO at a similar price, and the Philips beats them on the guest code experience. One buyer said the key fobs for the B098KMW17J are "a joke," and I'd agree: they're flimsy and easy to lose.

The Fingerprint Smart Door Lock (B07Y5V15SY) is the one I'd skip. At $67.96, it's priced right, but the guest code management is awkward. The app requires you to create a code, then assign it to a specific user profile, then manually delete it when you're done. It's not hard, but it's not intuitive, and I found myself double-checking whether a code was still active. The fingerprint reader is also mediocre: it worked about 90% of the time for me, which sounds fine until you're standing in the rain with groceries.

How to actually manage guest codes

Here's the part that matters. The setup order is the same for almost every lock on this list: pair the lock to the app first, then the gateway if there is one, then test the deadbolt. If you did it backwards, factory reset and start over. I've done it twice this month, and the manual won't tell you.

For temporary codes, the process is usually the same: open the app, find the "Users" or "Guests" section, tap "Add," enter a name and a code, and set an expiration date if you want one. The Philips is the best at this because it has a dedicated Guest section and lets you text the code directly. The TEEHO is basic but functional. The Yamiry is clunkier, but it works.

One tip: always set an expiration date, even for friends. You can always extend it later, but a code that never expires is a security hole. I've seen landlords leave the same code active for years because they forgot to delete it, and that's how you get a former tenant who can still walk in.

The bottom line

The Philips is the best lock for guest codes at $84.99, and the TEEHO is the best budget option at $55.97. If you're renting out a property, the Philips pays for itself in the first month you don't have to drive across town to hand over a key. If you just want to let your sister in without a spare key, the TEEHO does the job for less. Buy the Philips. Skip the Fingerprint Smart Door Lock. And for the love of everything, pair the gateway before you pair the lock. Trust me.
