⚡ Quick Answer:
Most smart locks use the same pin tumbler cylinders found in traditional deadbolts, which means the physical lock can still be picked. However, smart locks add digital layers — app control, auto-lock, and tamper alerts — that reduce certain risks while introducing new ones like wireless attacks and battery failure.
If you’ve ever wondered whether switching to a smart lock actually makes your door harder to get through, you’re not alone. The question of whether smart locks are pickable comes up constantly — and the honest answer is more nuanced than most product pages will tell you.
In this guide, we’ll walk through how smart lock cylinders work physically, what “picking” actually means in both traditional and digital contexts, which vulnerabilities are most relevant for typical homeowners, and what you can do to strengthen your setup without overclaiming what any lock can promise.

What Does It Mean for a Lock to Be “Pickable”?
Lock picking is the practice of manipulating the internal components of a lock — most commonly the pins inside a pin tumbler cylinder — to open it without the original key. A picker uses tension and a pick tool to push each pin to the shear line one at a time until the cylinder turns freely.
Standard residential deadbolts, including the cylinders used in most smart locks, operate on this same pin tumbler principle. That means the physical cylinder in many smart locks can, in theory, be picked by someone with the right tools and enough practice. The word “pickable” refers specifically to this physical mechanical vulnerability.
However, picking a lock is not the same as walking through someone’s door. Most opportunistic break-ins involve brute force — kicking a door in or breaking a window — rather than the quiet, skilled technique of lock picking. Understanding this distinction helps you make smarter decisions about where to invest in your home’s security.
📝 Note
Lock picking requires specific tools, time, and skill. Studies by security researchers suggest most residential burglaries involve forced entry through doors or windows — not lock picking. That said, understanding your lock’s vulnerabilities is still a sensible step in a layered security approach.
How Smart Locks Are Built — The Physical Side
Most smart locks are designed to retrofit onto your existing deadbolt. They replace the interior thumb-turn and sometimes the entire lock body, but many keep the existing keyed exterior cylinder. That cylinder is usually a standard Grade 1 or Grade 2 pin tumbler lock — the same type used in millions of conventional deadbolts across the country.
Some smart locks — particularly models like the Schlage Encode or the Yale Assure series — include upgraded cylinders with anti-pick pins, security pins, or restricted keyways that make manipulation significantly harder. Others use lower-grade cylinders where the exterior key slot is considered a backup entry method, with the assumption that most users will rely on the keypad or app instead.
This matters because if the cylinder is low-grade, anyone who bypasses the app and goes straight for the key slot faces less resistance than they would with a higher-grade lock. When evaluating whether smart locks are pickable, the cylinder grade is the first thing to examine.
Comparison: Smart Lock Cylinder Types
📊 Physical Attack Methods — Relative Difficulty (Practical Guide)
These bars represent typical relative difficulty — not scientific benchmarks — based on general security knowledge.
Kicking / Forced Entry
Very common — most break-ins use brute force
Lock Bumping (bump key)
Moderate difficulty — requires bump key and some practice
Traditional Lock Picking
Requires skill, tools, and uninterrupted time
Wireless / Relay Attack on Smart Lock
Targeted attack — needs specific equipment and proximity
Credential Theft (app/PIN compromise)
Uncommon but possible — usually through phishing or weak PINs
Looking at this range of attack types helps put the “pickable” question in perspective. Physical picking is one method among several — and not the most common threat most homeowners face.
Digital Vulnerabilities: The Risks Unique to Smart Locks
Beyond the cylinder, smart locks introduce vulnerabilities that traditional deadbolts don’t have at all. These are worth understanding before deciding whether smart locks are pickable in a broader sense — because digital attacks don’t require picking tools.
Common Digital Threat Scenarios
The Cybersecurity and Infrastructure Security Agency (CISA) recommends keeping smart home device firmware up to date and enabling two-factor authentication wherever available as a foundational step for any connected device.
🔐 Smart Lock Digital Security Decision Path
Walk through these questions to evaluate your current digital setup.
Step 1: Is your lock’s app account protected with a strong, unique password?
✅ Yes → Proceed to Step 2 | ❌ No → Change it now before anything else
Step 2: Is two-factor authentication (2FA) enabled on the app?
✅ Yes → Proceed to Step 3 | ❌ No → Enable it in app settings immediately
Step 3: Is the lock firmware on the latest version?
✅ Yes → Proceed to Step 4 | ❌ No → Check the manufacturer app for an update
Step 4: Is your home Wi-Fi router on a strong, unique password?
✅ Yes → Your digital layer is reasonably hardened | ❌ No → Update router credentials now
Step 5: Do you have battery alerts enabled or a backup entry method ready?
✅ Yes → Good operational redundancy | ❌ No → Enable low-battery alerts in app settings
Bump Keys and Other Physical Bypass Methods
Lock bumping is a technique that uses a specially cut “bump key” combined with impact to jolt the pins in a standard cylinder above the shear line, allowing the lock to turn. It’s faster and requires less skill than traditional picking, which is why it gets significant attention in security discussions.
Many smart locks — particularly those from Schlage — include anti-bump technology built into the cylinder. Others rely on standard cylinders without this protection. If you’re evaluating whether smart locks are pickable or bumpable, checking whether the manufacturer explicitly mentions anti-pick and anti-bump ratings is a practical starting point.
Deadbolt strength also matters here. Even if a lock cylinder resists picking, a weak door frame or a short bolt throw can be defeated with a kick. A smart lock with a Grade 1 cylinder installed in a hollow-core door with a worn strike plate offers less real-world protection than the cylinder rating alone would suggest.
⚠️ Warning
Do not assume a high security rating on the lock alone is sufficient. Door frame reinforcement, a longer bolt throw (at least 1 inch), and a heavy-duty strike plate with 3-inch screws are part of the overall picture. A strong lock in a weak door frame may still fail under forced entry. If you’re unsure about your door frame condition, consult a licensed door installer or locksmith.
Safe Smart Lock Setup vs Risky Setup Choices
Which Smart Locks Offer Stronger Pick Resistance?
Not all smart locks use the same cylinder quality, and this is one area where brand and model selection genuinely matters. When thinking about whether smart locks are pickable, the cylinder specification is your primary physical indicator.
Schlage smart locks — such as the Encode Plus and the B60N series — are frequently noted by locksmiths and security writers for including Schlage’s proprietary pin technology that may resist picking and bumping better than standard cylinders. Yale Assure locks include Yale’s own cylinder options. August smart locks, by contrast, tend to retrofit onto your existing deadbolt, which means pick resistance depends entirely on the cylinder you already have installed.
💡 Tip
If you’re retrofitting a smart lock module onto an existing deadbolt (like an August or Level lock), evaluate your existing cylinder first. If it’s an older builder-grade lock, consider replacing the full deadbolt assembly with a higher-grade cylinder — then add the smart module on top. This gives you better physical security without sacrificing the smart features.

🏠 Renters
A retrofit smart lock (like August or Level) that attaches to the existing interior thumb-turn without replacing the cylinder is typically the easiest option that may comply with most lease agreements. Always check with your landlord first.
🏡 Homeowners — Single Entry Point
A full deadbolt replacement with a Grade 1 smart lock (like Schlage Encode) may offer better physical and digital security. Combined with door frame reinforcement, this setup is a meaningful upgrade from a builder-grade lock.
👨👩👧 Families with Multiple Users
Keypad-equipped smart locks with guest code functionality allow separate codes for each family member. This eliminates shared key risks and lets you revoke access easily if a code is compromised or shared accidentally.
🏘️ Short-Term Rental Hosts
Remotely managed smart locks with time-limited access codes are common in Airbnb and VRBO setups. Choose a model with tamper alerts and access logs. Make sure your lock app allows easy code rotation between guest stays.

How to Evaluate Your Smart Lock’s Physical and Digital Security
Whether you already own a smart lock or are deciding which to buy, walking through these steps can help you identify any gaps in your current setup.
Red Flags That Your Smart Lock Setup Needs Attention
Even after installation, your smart lock setup can develop weaknesses over time. These are the warning signs that something needs to be checked or corrected.
🚩 Smart Lock Red-Flag Checklist
If any of these apply to your setup, address them promptly.
🔴 Your PIN code hasn’t changed in over 6 months
Codes shared with guests or service workers should be rotated regularly.
🔴 You’ve never checked your lock’s firmware version
Unpatched firmware can contain known vulnerabilities that have already been fixed in later releases.
🟠 Your lock app account uses the same password as other services
A data breach at any other site can expose your lock account if passwords are reused.
🟠 You have no backup entry method if the battery dies
Dead batteries can leave you locked out. Keep a physical key or know your lock’s emergency power option.
🟡 Your door has visible fingerprint smudges around the keypad
Smudge patterns can narrow down which digits are used. Wipe the keypad periodically and use longer PIN codes.
🟡 Access log shows entries you don’t recognize
Review your lock’s entry history regularly. Unexpected entries should be investigated promptly and access codes audited.
Common Smart Lock Mistakes and Better Choices
In my experience testing and researching smart locks, a handful of setup and purchase mistakes come up repeatedly. Knowing them in advance can save you from creating vulnerabilities that undercut the benefits of upgrading.
Mistakes vs. Better Choices
Privacy and Data Considerations for Smart Lock Owners
Smart locks that connect to the cloud collect data about when your door opens and closes, who has access, and from which device. Understanding what that data is, where it goes, and how it’s stored is part of responsible smart lock ownership.
Before purchasing, review the manufacturer’s privacy policy for answers to these questions: Is access log data stored in the cloud? For how long? Is it shared with third parties? Can you delete your data? Is communication between the lock and app encrypted?
The Federal Trade Commission (FTC) provides guidance on connected device privacy that’s useful for any homeowner evaluating smart home products. The FTC recommends reviewing manufacturer privacy policies before buying any IoT device, and considering whether the data collected is proportionate to the features you actually need.
For users with higher privacy concerns, some smart locks support local operation over Z-Wave or Zigbee without requiring cloud connectivity. These setups process commands locally through a smart home hub like SmartThings or Home Assistant, which can reduce the amount of data sent to external servers. However, local-only setups come with their own tradeoffs — typically less convenient remote access.
🛡️ Safety Note
If you’re setting up a smart lock on a network shared with a business or a home office, consider placing smart home devices on a separate IoT network segment. This limits the potential lateral movement if any single device were ever compromised. Most modern routers support guest network separation as a basic feature. For detailed guidance on network segmentation, CISA’s network security resources are a useful reference.

Smart Locks Worth Considering
If you’re in the market for a smart lock and want to prioritize physical security alongside smart features, the options below are commonly referenced for their cylinder quality and feature sets. As always, verify specifications with the manufacturer before purchasing.
Schlage Encode Plus Smart WiFi Deadbolt
A Grade 1 deadbolt with a built-in Wi-Fi connection that may support consistent app-based access without needing a separate hub. Commonly noted for its cylinder resistance features and compatibility with Apple Home Key. Requires standard deadbolt door prep.
Yale Assure Lock 2 with Wi-Fi
A keypad-equipped smart lock that may support flexible access code management for households with multiple users. Grade 2 construction with a touchscreen keypad and no key slot on some models — reducing the key-picking concern entirely. Compatible with major smart home platforms.
August Wi-Fi Smart Lock (4th Gen)
A retrofit interior module that attaches to your existing deadbolt thumb-turn. Useful for renters or anyone who wants smart access without replacing their exterior cylinder. Physical security depends entirely on the existing deadbolt — pair with a Grade 1 cylinder for best results.
🔧 When to Contact a Professional
- Your door frame is visibly damaged, warped, or showing wood rot — a locksmith or door installer can assess whether the frame needs reinforcement before installing any new hardware.
- You live in a rental and are unsure whether smart lock installation is permitted — check your lease and consult your landlord or property manager before drilling or modifying any door hardware.
- You want to install a smart lock that requires hardwired power (some commercial models do) — this requires a licensed electrician and may require a permit depending on your location.
- You’re choosing a lock for a commercial property, a multi-unit building, or any application where building code compliance may apply — consult a licensed locksmith or security integrator familiar with local codes.
- Your access logs show repeated unrecognized entries — this warrants both a security investigation and potentially contacting local law enforcement, not just a lock change.
Frequently Asked Questions
Are smart locks pickable the same way traditional locks are?
Most smart locks use pin tumbler cylinders that are physically pickable in the same way as traditional deadbolts. However, many mid- to higher-grade smart locks include security pins and anti-pick cylinder features that increase resistance. The smart electronics do not themselves prevent physical picking — the cylinder quality does.
Can someone hack into a smart lock remotely?
A remote compromise is theoretically possible if the lock’s app account uses a weak or reused password and two-factor authentication is not enabled. Attackers who gain access to your account credentials can potentially unlock the door remotely. Enabling 2FA, using a strong unique password, and keeping firmware updated significantly reduces this risk.
Is a smart lock more secure than a regular deadbolt?
It depends on the models being compared. A Grade 1 smart lock installed on a reinforced door with 2FA enabled may offer more overall protection than an older builder-grade deadbolt with a standard cylinder. But a low-grade smart lock installed on a weak door frame may offer less physical resistance than a quality traditional deadbolt. The smart features add digital layers, not automatic physical superiority.
What happens if my smart lock battery dies — am I locked out?
Most smart locks provide low-battery alerts well before the battery fails. Many also include a physical key backup or a 9V battery emergency terminal on the exterior that can temporarily power the lock enough to enter a code. Keep a physical key accessible and make sure battery alerts are enabled in your app to avoid being caught off guard.
Can someone guess my PIN from the smudges on the keypad?
Yes — fingerprint residue on frequently pressed digits can reveal which numbers are used in your PIN. To mitigate this, use a longer PIN code, periodically wipe down the keypad, and consider using the “scramble pad” feature available on some models, which randomizes the digit layout each time.
Do I need a hub for a smart lock to work?
Many popular smart locks include built-in Wi-Fi and work directly with their companion app without a separate hub. Others use Z-Wave or Zigbee and require a compatible hub like SmartThings, Home Assistant, or Wink. Bluetooth-only models work without Wi-Fi but require your phone to be within range. Check the connectivity type before purchasing to match your existing setup.
Are smart locks safe for renters to install?
Retrofit smart locks that attach to the interior thumb-turn without modifying the exterior cylinder or door hardware are typically the most lease-friendly option. However, always check your lease agreement and get your landlord’s permission before installing any lock hardware. Some landlords may require the original lock to be reinstalled when you move out.
Final Thoughts
The question of whether smart locks are pickable doesn’t have a single yes or no answer. Physically, most smart locks use the same cylinder mechanisms as traditional deadbolts — which means a skilled picker with the right tools could, in theory, manipulate the pins. The relevant question is whether your specific lock has security pins, an anti-pick cylinder, and a sufficiently strong ANSI grade to slow that process meaningfully.
Beyond picking, smart locks introduce digital considerations that traditional locks don’t have — app account security, firmware updates, wireless communication protocols, and battery management. Addressing these layers is just as important as the physical cylinder grade.
The best approach is a layered one: a quality cylinder, a reinforced door frame, strong digital credentials, and a broader home security setup that includes sensors and visible deterrents. For complex installations or commercial applications, consult a licensed locksmith or security integrator who can evaluate your specific door, frame, and building code requirements.
