We don’t own these locks and we don’t run a lab. Everything below is read from each manufacturer’s published install method and access features, applied to the specific mess of a shared tenancy. Our Lease-Safe rating is editorial and derived from the published install method — not a test result.
Start here: everything must be retrofit
In a house share the door is rarely just yours, and it is never the landlord’s problem to solve. That makes the rule stricter than it is for a solo renter: only a retrofit lock will do. A retrofit fits over the interior of the deadbolt you already have, so the exterior of the door and every existing key keep working exactly as before.
That matters in a share for a reason it doesn’t elsewhere. If you replace the deadbolt, you have unilaterally changed the locks on a door other tenants have a legal right to use, and possibly locked out a landlord who is entitled to access with notice. That’s a real dispute. With a retrofit, everyone’s existing key still works, nothing is taken away from anyone, and you have only added a way in. All three picks here are retrofits or adhesive accessories, and all three are rated Excellent for lease-safety.
How to hand out codes without it going wrong
One code per person, never a house code.A single shared PIN is a key with extra steps: you can’t tell who used it, and revoking it means resetting everyone. Individual codes cost nothing to create and are the entire point of the exercise.
Temporary codes for temporary people.Cleaners, a landlord’s contractor, someone feeding the cat for a fortnight, a friend crashing between flats. Issue, use, delete. This is the closest a rented door gets to actual access control.
Delete a code the day someone moves out, not the week after. The handover afternoon is when everyone remembers; a week later nobody does. Make it part of the same conversation as the deposit.
Do not use a birthday, a house number, or a leaver’s old code reissued. The whole security model rests on codes being unguessable and genuinely individual.
Which lock, and why
The Yale Approachis the one we’d put on a shared front door. The keypad is in the box and mounts with adhesive, so there’s nothing to buy separately and no hole in a frame nobody in the house owns. For a group of people who each need their own way in, having the exterior half solved out of the box is worth paying for — our full Yale Approach review covers the Wi-Fi bridge caveat you should know about first.
The SwitchBot Keypad Touch is the cheaper route to the same place if you already own or plan to buy a SwitchBot lock. It sticks to the wall beside the door, adds PIN and fingerprint entry, and stores codes locally. In a house where one person forgets a four-digit code with impressive consistency, a fingerprint is a genuinely practical answer.
The August Wi-Fi Smart Locktakes the opposite approach: no keypad, and everything through the app. Its advantage in a share is built-in Wi-Fi — you can let someone in remotely, from work, without anyone owning anything physical. Its disadvantage is that it only works for people with the app, a phone with charge, and enough goodwill to install it, which in a house of five is a meaningful assumption. Our August review goes deeper.
The conversations to have before you buy
Ask the landlord, even though you technically may not have to.A retrofit changes nothing about their property and most agreements don’t cover it. But in a shared tenancy, a landlord who arrives to find an unfamiliar keypad beside the door and no warning tends to react badly, and you gain very little by surprising them. A one-line message — it’s reversible, your key still works, it comes off at the end — almost always gets a yes. Nolo’s tenant-rights material is a decent primer on where alteration lines fall if you want to be precise about it, and our can I add a lock to my apartment guide covers the same ground for a solo tenancy.
Agree who administers it.Whoever’s phone the lock is paired to holds a small amount of power over everybody else’s front door, and that is worth naming out loud rather than discovering during an argument. Most locks support more than one admin; use that.
Agree who owns it when the house breaks up.It’s the person who paid for it, obviously — but write that in the group chat now rather than negotiating it on the last day of the tenancy. And whoever takes it: reset it to factory before it goes on a different door, so no old code survives the move.
Split it, if you can. A retrofit lock across four people is a genuinely small amount each for something everyone uses daily and everyone benefits from. It also settles the ownership question by making it collective.
What a smart lock still won’t fix
It secures the front door. It does nothing at all about the door to your own room, which in a share is frequently the door you actually care about — and which you almost certainly can’t fit a lock to without asking. For that, a portable lock that slots into the existing strike plate is the honest answer: no install, no permission, no hole, and it goes in a suitcase. Pair it with a cheap adhesive door alarm and you have covered your own space properly.
It also can’t tell you who was in the house, only which code opened the door. If that’s the question you’re really asking, read our guide to cameras in a rented room first — there are real limits, legal and social, on pointing one at shared space, and it’s much better to know them before you buy than after.
