Here is the honest answer first: there is no universal patio door smart lock you can buy off the shelf. Most hinged and French patio doors lock with a multipoint system, not a normal deadbolt, and normal smart deadbolts cannot drive it. One true exception exists — the Yale Assure Lock built for Andersen patio doors — and for everyone else, three routes actually work: a smart deadbolt swap, a retrofit unit, or keeping your multipoint lock and adding smart monitoring.
This guide is for swinging patio doors: single hinged doors and double French doors. It first shows you how to tell which lock type your door has, then matches each type to the option that genuinely fits. Every price was checked on the maker’s or a specialist retailer’s own page on October 19, 2026.
Your options at a glance:
- Andersen multipoint door: Yale Assure Lock for Andersen (YRM276) — $531.70 Z-Wave or $629.08 Wi-Fi at GoKeyless
- Single-point door with a standard deadbolt: swap in a smart deadbolt, for example the Schlage Encode Plus — from $329.00 at Schlage
- Same door, less work: a retrofit unit over your existing deadbolt — August Smart Lock + Connect kit, $199.99 at August
- Any other multipoint door: keep the lock, add an Aqara Door and Window Sensor P2 — $34.99 at Aqara’s US store
Why Patio Doors Break the Normal Smart Lock Rules
A front-door smart deadbolt assumes your door has one deadbolt in one standard hole. Patio doors often work completely differently, and that difference decides everything in this guide.
How a multipoint lock works
A multipoint lock runs the full height of the door edge. When you lift the handle, hooks or bolts at the top, middle, and bottom of the door swing into the frame. Turning the key or thumbturn then locks the whole system in place.
That design does two jobs at once. It spreads force across three or more locking points instead of one, and it pulls the tall door evenly into its seals, which is why multipoint doors resist drafts so well. As one hardware maker puts it in its own FAQ, a deadbolt protects a point, while a multipoint system protects the whole edge.
The problem for smart locks is the drive. A multipoint system is powered by a gearbox and a long rail inside the door, worked by the handle. There is no standalone deadbolt in a standard 2-1/8 inch bore with a simple tailpiece for a motor to grab. A normal smart deadbolt has nothing to connect to.
Single-point vs. multipoint: the 30-second check
Do this before you shop. Close your patio door and look at how it locks:
- You lift the handle up to engage the lock, then turn a key or thumbturn: that is a multipoint door. Also look for extra hooks or bolts along the door edge, above and below the handle.
- Your door has a separate deadbolt above or beside the handle, in its own round hole: that is a single-point door, and it behaves like a front door. Standard smart deadbolts and retrofits are back on the table.
- Your handle only latches, with a small thumbturn in the handle itself: read the brand label on the lock mechanism or the etched logo in the corner of the glass before assuming anything. Many of these are multipoint systems in disguise.
French doors: only the active leaf counts
On double French doors, one leaf is active and carries the handle and lock. The other leaf is inactive and is held by flush bolts at the top and bottom, which you slide by hand.
Any smart lock only ever goes on the active leaf, and it only ever controls that leaf’s lock. If the inactive leaf’s flush bolts are not thrown, the pair is far weaker than the lock suggests. Make throwing both flush bolts part of your locking routine, smart lock or not.
The One Smart Lock Built for Multipoint Patio Doors: Yale Assure for Andersen
If your hinged patio door is an Andersen, you are the exception to the rule. Yale makes a version of its Assure Lock specifically for Andersen patio doors, and Andersen itself confirms it in its patio door FAQ: the Yale Assure Lock is available on their patio doors and front doors, with monitoring, locking, and unlocking from anywhere.
The Yale Assure Lock for Andersen (model YRM276) replaces the deadbolt area of the Andersen multipoint hardware with a motorized, key-free touchscreen unit. You still lift the handle the way you always have. The smart unit drives the locking point your thumbturn used to turn, and GoKeyless, the lock specialist that sells it, lists its locking device plainly as “Multipoint.”
What you get:
- Keypad codes (4 to 8 digits), one-touch locking by tapping the keypad, and an interior thumbturn
- A door position sensor that tells the app whether the door is open or closed, not just locked or unlocked
- No key cylinder at all, so there is nothing to pick or bump — and no key backup either
- 9-volt battery contacts on the outside, so dead batteries do not lock you out if you have a spare 9V handy
- Four AA batteries; GoKeyless lists battery life at about a year
Price: the Z-Wave model (YRM276-ZW2) is $531.70 at GoKeyless (list price $699.00), and the Wi-Fi and Bluetooth model (YRM276-CB1), which includes the Connect Wi-Fi Bridge, is $629.08 at GoKeyless — both checked October 19, 2026. The Z-Wave version needs a Z-Wave hub or alarm system for remote control; the Wi-Fi version works with the Yale Access app out of the box. Andersen dealers also sell this lock, and prices vary by finish.
Check your series before you order. The lock fits Andersen A-Series hinged patio doors, E-Series patio doors from March 2018 and newer, entry doors, and folding patio doors. The 400 Series is not on the list. The Yale manual’s identification steps use the locking instruction label on the door mechanism: A-Series doors carry a red label, while 400 Series doors carry a black one. Check yours first — this is an expensive lock to buy for the wrong door.
Best for: Andersen A-Series and newer E-Series owners who want real keypad and app control on a multipoint door. Keep in mind: it fits Andersen doors only. Pella, Marvin, and other multipoint brands use different internal gear, and this lock does not fit them.
When No True Smart Lock Fits: Three Routes That Work
If your door is not a compatible Andersen, no big-brand smart lock replaces your multipoint hardware today. That is the plain state of the US market in October 2026. You still have three honest routes, and the right one depends on the check you did above.
All four routes compared: fit, what you get, and price checked on October 19, 2026
| Route | Fits which doors | What you get | Price |
|---|---|---|---|
| Yale Assure Lock for Andersen (YRM276) | Andersen A-Series hinged and E-Series (2018+) multipoint doors | Keypad codes, app control, remote lock and unlock, door sensor | $531.70 Z-Wave / $629.08 Wi-Fi at GoKeyless |
| Smart deadbolt swap (example: Schlage Encode Plus) | Single-point patio and French doors with a standard deadbolt | A full smart deadbolt: codes, app, voice, auto-lock | From $329.00 at Schlage |
| Retrofit unit (August Smart Lock + Connect) | Single-point doors with a standard single-cylinder deadbolt | App control over your existing deadbolt; outside hardware and keys unchanged | $199.99 at August |
| Keep the multipoint lock + contact sensor (Aqara P2) | Any multipoint door, any brand | Open and closed alerts and automations; locking stays manual | $34.99 at Aqara’s US store |
Route 1: swap in a smart deadbolt (single-point doors)
If your patio or French door has a standard deadbolt in a standard bore, treat it like a front door. Schlage says it directly in its French door guide: its electronic and smart locks are compatible with standard doors, so you can install one on French or double doors the same way you would a mechanical deadbolt.
The Schlage Encode Plus is the strong default here: built-in Wi-Fi, up to 100 codes, Apple Home Key, and Schlage’s top BHMA rating. Price: from $329.00 at Schlage.com, checked October 19, 2026. If you want codes without any app at all, the Schlage Camelot Keypad Deadbolt (BE365) is the simple baseline at $129.00 at Home Depot, per Schlage’s product page (list $169.00), checked the same day. Our guide to the best door locks for home compares the strongest standard deadbolts if your door takes this route.
Route 2: a retrofit unit over your existing deadbolt
Retrofits keep your outside hardware and your keys, and motorize the inside thumbturn instead. The August Smart Lock + Connect kit is $199.99 at August.com, checked October 19, 2026, and August specifies a standard single-cylinder deadbolt. The SwitchBot Lock Ultra, which clamps over many thumbturn and knob cylinders with adapters, is another option; its Vision Combo with hub and keypad is $249.99 at SwitchBot’s US store, checked the same day.
The limit matters: a retrofit needs that standard single-cylinder deadbolt to grab. It cannot drive a multipoint gearbox, and it cannot fix a door whose deadbolt is stiff. If turning your thumbturn takes real effort today, fix the door first — a small motor is weaker than your hand.
Route 3: keep the multipoint lock, add smart awareness
Here is the option most multipoint owners should start with. Your multipoint lock is already the strongest hardware on the door — stronger, point for point, than the deadbolt a smart lock would give you. What it lacks is awareness: it cannot tell you the door was left unlocked.
A contact sensor closes that gap for very little money. The Aqara Door and Window Sensor P2 is $34.99 at Aqara’s US store, checked October 19, 2026. It reports open and closed status over Matter and Thread (you need a Thread border router, which many Apple, Google, and Amazon households already own), so your phone can alert you when the patio door opens, or remind you at bedtime if it was left open. It does not lock anything. Pair it with the habit of lifting the handle fully and locking every time, and you have most of the real-world benefit at a tenth of the price.
One more route exists for a few doors: specialist smart-lock shops retrofit some multipoint systems, including Pella doors, after reviewing photos and measurements of your door. The Connected Shop describes exactly this process for Pella multipoint doors. Expect a consultative quote rather than a shelf price, and ask any such shop which gearbox they support before paying anything.
What About a Sliding Patio Door?
Sliding panels are a different problem. They latch sideways with hooks, they have no deadbolt and no multipoint rail of the hinged kind, and none of the options above fit them. A handful of purpose-built smart locks and strong manual double-bolt locks exist for sliders, and we cover them in depth in our guide to the sliding glass door smart lock. If your patio door slides, that guide is the right one — everything else in this article is about doors that swing.
Weather, Swelling, and Alignment: The Patio Door Realities
Patio doors live harder lives than front doors. They are tall, mostly glass, and they open onto weather. Three realities shape what works:
- Alignment drifts. Hinges sag a little, houses settle, and doors swell in humid months and shrink in dry ones. A multipoint door that lifts and locks smoothly in spring can bind by August. Any motor — in a smart lock or a retrofit — stalls or chews through batteries when it has to force a binding bolt.
- The seal is part of the lock. A multipoint system earns its keep by pulling the door evenly into the weatherstripping along its full height. If the seal is flattened or torn, you get drafts even when the door is locked properly. Our door weatherstripping guide shows how to test and replace worn seals.
- Heat and cold reach the hardware. A sun-baked patio door gets hot, and cold snaps shorten battery life on any battery lock. The electronics of the options above sit on the inside face, which helps — but plan on battery checks before winter, not after a failure.
💡 Practical Home Tip: Always lift the handle fully before you turn the key or thumbturn. A half-lifted multipoint door can feel locked while only the latch is holding it — the hooks never engaged. And if lifting the handle ever needs a shoulder behind it, your door has dropped: adjust the hinges or call a door professional before spending anything on smart hardware, because a motor cannot fix alignment.
How to Choose the Right Patio Door Smart Lock
Work through these five steps in order. The first two decide everything; the rest is preference.
- Do the handle test. Lift-to-lock means multipoint. A separate deadbolt in its own hole means single-point. Your route is chosen by this test, not by a product page.
- Read the labels. Find the brand etched in the glass corner and the label on the lock mechanism. Andersen owners: red A-Series label, good news; black 400 Series label, the Yale does not fit.
- Match the route. Compatible Andersen → the Yale YRM276. Single-point → deadbolt swap or retrofit. Other multipoint → sensor now, and a specialist quote only if you truly need powered locking.
- Pick the connection you already own. Z-Wave Yale ($531.70) makes sense if you run a Z-Wave hub or alarm; the Wi-Fi Yale ($629.08) if you do not. Same logic applies to sensors and retrofits: buy for the hub or border router already in your house.
- Tune the door before you install anything. Hinges tight, handle lift smooth, seals intact, both French flush bolts working. Ten minutes of tune-up is worth more than any feature on the box. New to smart locks entirely? Our smart key lock guide explains the types and features in plain words first.
Mistakes That Waste Money on Patio Doors
- Buying a standard smart deadbolt for a multipoint door. It cannot connect to the gearbox, and no adapter fixes that. It is the most common and most expensive mistake in this category.
- Ordering the Yale without checking the series. It fits A-Series and newer E-Series Andersen doors. It does not fit the 400 Series, and it does not fit Pella, Marvin, or any other brand.
- Mixing up sliding and hinged hardware. Sliding-door locks, hooks, and bars do not fit swinging doors, and the reverse is also true. Confirm which way your door moves before ordering anything.
- Forgetting the inactive French leaf. A smart lock on the active leaf does nothing about unthrown flush bolts on the other leaf.
- Motorizing a stiff door. If the handle lift or thumbturn is hard work for you, it is impossible work for a small motor. Fix alignment first.
- Skipping the hub check. The Z-Wave Yale needs a Z-Wave system for remote control, and the Aqara sensor needs a Thread border router. Confirm what you own before you pay for features you cannot switch on.
Frequently Asked Questions
Can you put a smart lock on French doors?
Yes, when the French door has a standard deadbolt. Schlage’s own guidance is that its smart locks install on French and double doors the same way as a mechanical deadbolt. If your French doors use a multipoint system instead — handle lifts to lock — a standard smart deadbolt will not fit, and the routes in this guide apply.
Are multipoint locks more secure than deadbolts?
Against forced entry, yes. A deadbolt secures one point at the center of the door, so a kick concentrates its force there. A multipoint lock anchors the door at three or more points spread along its height, dividing the same force across the door and frame. No lock makes a door impossible to open, but multipoint removes the easiest ways in.
Can French doors be locked?
Yes. French doors lock with their included hardware: the active leaf carries a handle and lock (often multipoint), and the inactive leaf is secured by flush bolts at the top and bottom. Pella notes the same in its hinged patio door answers, and adds that optional multipoint locks increase security further. Both leaves must be secured for the pair to be locked in any real sense.
Are French doors safe?
They can be. Pella’s answer is that French doors are safe and include locking hardware — and the honest addition is that safety depends on using all of it: multipoint engaged, flush bolts thrown, and glass treated as the weak point it is. A quality multipoint French door, fully locked, is a strong door. The same door on its latch alone is not.
Does anyone make a smart lock for multipoint patio doors?
Barely. In the US today, the one mainstream answer is Yale’s Assure Lock for Andersen, built for Andersen’s multipoint doors at $531.70 to $629.08 depending on the radio. Europe’s best-known multipoint smart handle, Yale’s Conexis, is not sold or supported in the US. For non-Andersen multipoint doors, monitoring with a sensor is the practical smart upgrade.
What about a sliding patio door?
None of the locks in this guide fit a sliding panel — sliders latch sideways and need their own hardware. Purpose-built smart options and strong manual double-bolt locks do exist for them, and our sliding glass door smart lock guide covers what fits, what it costs, and the anti-lift fixes that matter more than the lock.
A short disclaimer: this guide is general information for homeowners, not professional security advice, and it cannot judge your specific door. Products were checked on retailer and manufacturer pages on October 19, 2026; prices and compatibility lists can change. If your door is damaged, out of square, or protects a high-risk home, have a qualified locksmith or your door maker’s dealer assess it in person.
The Bottom Line
Start with the handle test, not a product page. Andersen multipoint owners have one true smart lock, the Yale YRM276, and it is a good one. Single-point patio and French doors can use the same smart deadbolts as a front door. Everyone else with a multipoint door should keep the strongest lock they already own, add a $34.99 sensor for awareness, and spend the savings on alignment and seals.
Your next step takes thirty seconds: close your patio door tonight and notice whether you lift the handle to lock it. That one observation tells you exactly which section of this guide is yours.
