We don’t own this lock and we don’t run a lab. What follows is read from what Yale publishes about the Approach’s design and install, assessed against the one thing we do have a defensible view on: whether a device leaves a rented door exactly as it found it. Our Lease-Safe rating is editorial and derived from the published install method — it is not a test result.
What “retrofit” actually means here
The Approach reuses the deadbolt already in your door. You unscrew the interior thumbturn, fit the Yale unit in its place over the same spindle, and that’s the lock done. Nothing changes on the outside of the door. Your key still works, exactly as before. There is no new hole, no new bore, no new strike plate — and critically, no visible difference from the corridor.
That last point is what makes this category worth paying for as a renter. A replacement deadbolt like the Wyze Lock Boltis a fine lock, but it puts unfamiliar hardware on the landlord’s door and takes their key out of circulation, which in most tenancies is a permission conversation and in some is a straight no. A retrofit sidesteps all of it. We rate the Approach Excellent for lease-safety on exactly that basis, and at move-out it comes off in about the time it took to fit.
The keypad, and why it’s adhesive
The Approach’s distinguishing feature is the exterior keypad Yale includes, and it’s a peel-and-stick mount, not a screwed one. That detail does a lot of work. A screwed keypad means two holes in a door frame you don’t own, which would drag the whole product back down to the same permission problem a replacement deadbolt has. Adhesive keeps the exterior side of this lock as reversible as the interior side, so the entire installation — both halves — leaves nothing behind.
The practical catch is that adhesive needs somewhere flat and smooth beside your door. Painted plaster, a smooth metal frame, a flat brick-effect panel: fine. Heavily textured render, rough brick, or a frame with no clear flat run at the right height: a problem worth checking before you order. Look at the specific patch of wall next to your door first — our adhesive mounting guidecovers which surfaces hold and which don’t, and how to prepare them so a keypad stays put through a winter.
What the keypad buys you is genuinely useful in a rental: codes instead of keys. A housemate who keeps losing theirs, a friend collecting a parcel, a landlord’s contractor who needs an hour on Tuesday — each gets a code, and codes can be deleted. A spare key cannot be un-copied.
The honest catch: the Wi-Fi bridge
Here is where the Approach is beaten by its own sibling, and it’s the single most important thing to understand before buying. The Approach communicates over Bluetooth. Bluetooth is enough for the lock to work while you’re there and for the keypad codes to function, but it is not enough to check the lock from work or let someone in while you’re out. For that you need the Yale/August Wi-Fi bridge, which is sometimes bundled and sometimes an extra purchase.
The August Wi-Fi Smart Lock, by contrast, has Wi-Fi built into the lock itself. No bridge, no accessory, no second thing plugged into a socket. If remote access is a feature you actually want, check carefully whether the Approach listing you’re looking at includes the bridge, because a bundled one and an unbundled one are effectively different products at different prices. Our August vs Yale comparison puts the two side by side on precisely this point.
Compatibility: check this before anything else
Every retrofit lock has one hard requirement: a standard single-cylinder deadbolt— key on the outside, thumbturn on the inside. Most apartment doors have one. But not all: double-cylinder deadbolts (key on both sides), mortice locks common in older buildings, and some multipoint European-style locks on newer builds will not take a retrofit at all.
Look at the inside of your own door before you order anything. If there’s a thumbturn you twist by hand, you are almost certainly fine. If there’s a keyhole on the inside too, or a long handle you lift to lock, you are not, and no retrofit lock on this site will fit — a portable lock or a door alarm is the better route for those doors. Yale publishes a compatibility list; spend two minutes on it.
Batteries, and what happens when they die
The Approach runs on AA cells. The reassuring part of a retrofit design is what a flat battery means: nothing dramatic. Your original key still works, from the outside, exactly as it did before the lock existed — because the deadbolt and keyway were never modified. That is a materially better failure mode than a replacement smart lock, where a dead battery can mean an emergency jump-start off a 9V terminal or a locksmith.
Carry the key you already have and this is a non-issue. It is also, incidentally, a good answer to the anxiety most people have about smart locks in general: the retrofit design means the mechanical lock underneath is untouched and always available.
Who should buy it — and who shouldn’t
Buy the Yale Approach if you want code entry on a rented door and you want it to work out of the box without buying a second accessory. Sharing access is the use case it wins on outright: housemates, a partner who stays some nights, a dog walker, a parent visiting for a week. It is our pick whenever a keypad is the requirement, and it sits high in the best smart locks for renters ranking for that reason.
Buy the August insteadif you don’t need a keypad and you do want remote access. It is cheaper, the interior unit is a little slimmer, and its built-in Wi-Fi means no bridge to buy or find a socket for. Most single renters who just want the door to lock itself behind them are better served by the August — our August review makes that case.
Consider the SwitchBot route if you like the keypad idea but want to mix and match. The SwitchBot lock plus its adhesive keypad reaches roughly the same place by a different path, and if you’re managing codes for several people it’s worth reading our smart locks for roommates page before you commit to either ecosystem.
