Most front door setups have two locks working independently a deadbolt up top and a knob or lever below. Locking one and forgetting the other is an easy habit to fall into, and it leaves your door less secure than it looks from the outside.
Interconnected smart locks solve that by linking both mechanisms so one action secures them together. We went through the current options to find the best interconnected smart locks that combine that mechanical advantage with app control, remote access, and reliable daily use.
If you want one recommendation for best interconnected smart locks, go with the Philips WiFi Smart Lock. It covers front door access and family security in one package, so you get the convenience of a single-action lock without giving up the layered protection of a deadbolt and latch working together. Browse our full list below to see which one works best for your situation.

Buying Guide for Best Interconnected Smart Locks
An interconnected lock is a specific piece of hardware, and not every smart lock qualifies. Understanding what makes one genuinely interconnected and what to look for beyond that label keeps you from buying something that only solves half the problem. Here is what to look at before you decide.
Mechanical Interconnect vs. Software Pairing
Some locks advertise interconnected behavior by syncing two separate devices through an app, which is not the same as a true mechanical interconnect. A real interconnected lock uses a physical linkage between the deadbolt and latch so that one turn or press engages both simultaneously.
This distinction matters for reliability. A software-synced setup can fall out of step if connectivity drops, while a mechanical interconnect works regardless of battery level or Wi-Fi status. Confirm the lock uses a physical mechanism before you buy.
Door Prep and Hardware Cutouts
Interconnected locks require specific door prep that differs from a standard deadbolt replacement. The lock body spans both the deadbolt and latch positions, so your door needs the right spacing between bore holes and the correct backset to match.
Measure your door’s existing hole spacing before ordering, and check whether your frame and strike plate need modification. If you want to handle the install yourself, smart locks designed for easy DIY installation are worth looking at, though interconnected models sometimes require more prep than a straight deadbolt swap.
Access Methods and Entry Flexibility
An interconnected lock on a front door usually serves everyone in the household, so the access methods need to cover different habits and ages. A keypad code works for most people; adding fingerprint or app access fills in the gaps for guests or situations where hands are full.
Look for a lock that supports multiple credential types and lets you manage them per user. If keyless entry is the main goal, options built around keyless access often overlap well with the interconnected category and give you a broader set of access methods to compare.
Smart Home and Remote Access
A front door lock that you can check or control remotely adds real value when you are managing deliveries, letting in a contractor, or just not sure if you locked up. Wi-Fi locks do this directly; Z-Wave or Zigbee models need a hub.
Think about what smart home setup you already have before deciding on a protocol. If you are already running Apple devices, HomeKit-compatible smart locks integrate cleanly with existing automations and keep the lock visible alongside your other devices.
Battery Life Under Load
Interconnected locks have more hardware to drive than a standard deadbolt the motor engages both the latch and the deadbolt simultaneously, which draws more current per cycle. On a busy front door, that adds up faster than most battery estimates assume.
Check the rated battery life against actual door usage and look for a model that sends low-battery alerts early. For households where a dead lock is a real inconvenience, locks with long battery life are worth prioritizing over feature count.
With those factors sorted, the right interconnected lock for your door becomes a much cleaner decision than the crowded market makes it look.

Final Thoughts
Picking the right interconnected lock comes down to what you actually need it to do.

FAQs
How do interconnected smart locks handle power outages?
Interconnected smart locks retain physical key backup so entry remains possible during outages. Most models also accept USB emergency power for app or code use when batteries drop. This setup works well on front doors that see daily family traffic where sudden power loss would otherwise block access.
Do interconnected smart locks require a hub?
Many interconnected models operate directly over Wi-Fi without a separate hub. Others need an existing HomeKit or Z-Wave bridge for full remote functions. Check your current network before purchase to avoid buying extra hardware for basic operation.
Can interconnected smart locks work with rental properties?
Interconnected smart locks install on standard doors without permanent modifications in many cases. Temporary codes allow owners to grant and remove access without rekeying. Confirm lease terms on modifications first, then select models that reverse to original hardware easily.
Is it better to choose fingerprint or keypad entry on interconnected locks?
Fingerprint entry speeds daily use for primary residents while keypads suit guests or visitors without stored biometrics. Most quality units include both methods for flexibility. Busy households benefit from the dual approach because it covers varied access needs without extra remotes.
How often should interconnected smart lock batteries be replaced?
Interconnected smart lock batteries typically last 12 months under normal use before replacement. App alerts usually appear weeks ahead to prevent unexpected lockouts. Keep a spare set on hand for high-use doors to maintain continuous protection.
