The Lockly locks Secure Pro sits at the intersection of biometric access control and conventional deadbolt design, making it one of the more technically layered smart locks available to residential and light-commercial users in the US and Canada. This Lockly Secure Pro review examines the lock’s core features, evaluates the security trade-offs that manufacturers rarely emphasize, breaks down realistic installation and service costs, and identifies the specific scenarios where a licensed locksmith should be involved rather than a DIY approach.
Lockly Secure Pro review overview
The Lockly Secure Pro is a Grade 2 ANSI-rated deadbolt that combines a 3D fingerprint reader, a patented PIN Genie randomized touchscreen, Bluetooth and Wi-Fi connectivity, and a traditional key cylinder. That combination addresses a common criticism of smart locks: single-point failure. If the battery dies, the app is unreachable, or the biometric reader malfunctions, the physical key provides a backup entry path.
The PIN Genie display is worth understanding in detail. Rather than a fixed numeric keypad, the display randomizes the position of digits on each use. This prevents shoulder-surfing attacks and reduces the smudge-pattern vulnerabilities that plague conventional touchscreen locks. Each access attempt presents digits in a new arrangement, so an observer watching from a distance cannot reliably decode a code by tracking finger positions.
The 3D fingerprint sensor uses sub-dermal imaging rather than surface scanning, which reduces false rejections caused by dry skin, minor cuts, or partial finger contact. In practical terms, this means the sensor performs more consistently across seasons and for users with worn fingerprints, a real-world concern for tradespeople and older adults. The lock stores up to 99 fingerprints, supporting households with multiple authorized users without requiring separate user accounts in the app.
On the connectivity side, the Secure Pro includes built-in Wi-Fi, removing the need for a separate Bluetooth-to-Wi-Fi bridge that earlier Lockly models required. The companion app supports remote locking, access log review, and temporary access codes with defined expiration windows. These features are broadly in line with competing smart locks in the $200–$300 retail price range.
Key factors in a Lockly Secure Pro assessment
Any honest Lockly Secure Pro evaluation must address the physical security of the lock cylinder and the door hardware it relies on. The Secure Pro ships with a Lockly-branded key cylinder that is not a high-security grade. It is not pick-resistant to the standard of Medeco lock products, Mul-T-Lock, or ASSA Abloy high-security cylinders. For most residential installations, this is an acceptable trade-off, but it means the smart features are not matched by an equivalently hardened mechanical fallback.
The deadbolt throw itself is a standard 1-inch bolt, consistent with Grade 2 classification. A Grade 1 deadbolt — the residential standard recommended by security consultants — offers a longer throw and heavier internal components. Homeowners on high-crime streets or with a prior forced-entry history should consider whether the Grade 2 rating meets their threat model. Upgrading the physical door frame reinforcement, strike plate anchoring, and hinge security will have a greater impact on forced-entry resistance than the smart lock brand selected.
Battery life is rated at approximately one year under normal use, relying on four AA alkaline batteries. The Wi-Fi radio draws more current than Bluetooth-only locks, so heavy remote-access users may see shorter intervals between replacements. The lock provides low-battery notifications through the app and an audible alert, and a 9-volt battery can be pressed against the exterior terminals to provide temporary power for a single entry if internal batteries are fully depleted — a detail worth committing to memory before a lockout occurs.
Access log retention and data privacy are factors that rarely appear in Lockly Secure Pro comparison discussions but matter for security-conscious users. Entry events are stored locally on the lock and synced to the app. Lockly’s cloud infrastructure processes remote access commands. Users operating under strict data governance requirements — rental property managers, small-business owners — should review Lockly’s current privacy policy to understand data retention and third-party sharing practices before deployment.
Costs and risks of the Lockly Secure Pro
The retail price of the Lockly Secure Pro ranges from approximately $200 to $280 depending on finish and retailer. That figure covers the lock hardware only. Installation involves removing an existing deadbolt, preparing the door for the new hardware dimensions, and configuring the app and Wi-Fi credentials. The process is documented clearly in the included instructions and typically takes 30–60 minutes for a straightforward retrofit on a standard door with existing deadbolt prep.
Risks increase with non-standard door configurations. Doors thicker than 2 inches, doors with offset bore dimensions, steel doors, or fiberglass doors with internal framing may require adapter kits, extended tailpieces, or professional fitting. Attempting to force a lock into a door that does not match the hardware specifications can damage the door, strip the mounting hardware, or result in a deadbolt that does not throw cleanly — leaving the home either unsecured or inaccessible.
Average: $85 · Range: $65–$120 · Travel: free in service area. That is a representative range for a locksmith to install a smart deadbolt on a standard residential door in most US and Canadian markets. If door prep modifications are needed — enlarging the bore, reinforcing a strike plate, or installing a door frame repair kit — expect additional charges of $30–$80 depending on scope. These costs are typically lower than the cost of repairing a damaged door from a forced or misaligned installation.
A less-discussed risk involves the Wi-Fi onboarding process. The Secure Pro connects to 2.4 GHz networks only and does not support 5 GHz bands. Homes with mesh networks that broadcast a unified SSID across both bands may experience pairing failures. The workaround — temporarily separating the 2.4 GHz band or using a guest network — is manageable but adds a configuration step that can frustrate less network-savvy users. If the lock loses its Wi-Fi credentials due to a router replacement or network reconfiguration, re-pairing requires physical proximity to the lock, which is straightforward for homeowners but may require a service call for property managers dealing with the issue remotely.
When to call a locksmith for Lockly Secure Pro service
There are four scenarios where professional locksmith involvement is appropriate rather than optional. The first is a lockout caused by battery failure when no 9-volt emergency power source is available and the physical key cannot be located. A locksmith can provide non-destructive entry using techniques appropriate to the lock cylinder, avoiding damage to the door or the smart lock hardware itself.
The second scenario is a malfunctioning deadbolt throw. If the Secure Pro’s bolt does not fully extend or retract — due to door warping, misalignment, or internal mechanical failure — forcing the handle or repeatedly cycling the lock can strip the clutch mechanism. A locksmith can assess whether the issue is door-related or hardware-related and determine whether adjustment, lubrication, or replacement is the appropriate remedy.
The third scenario is rekeying or cylinder replacement. The Secure Pro’s factory cylinder can be rekeyed to match an existing key system, which is valuable for landlords and property managers who want the smart features of the Lockly platform without introducing a separate key for the building. A licensed locksmith with access to the appropriate key blanks and pinning kit can rekey the cylinder to a master key system or a specific residential key profile.
The fourth scenario covers installation on non-standard doors. Aluminum-framed glass doors, solid-core doors with steel inserts, and commercial doors with multi-point locking systems require evaluation before a smart deadbolt installation proceeds. A locksmith can assess compatibility, source necessary adapters, and complete the installation in a way that does not compromise the door’s structural integrity or the lock’s warranty.
Recommended next steps for Lockly Secure Pro owners and buyers
For prospective buyers completing a Lockly Secure Pro analysis before purchase, the first practical step is measuring the existing door and deadbolt configuration. Confirm the door thickness, the backset measurement (the distance from the door edge to the center of the bore — typically 2-3/8 inches or 2-3/4 inches), and whether the existing deadbolt is a single-cylinder or double-cylinder configuration. The Secure Pro accommodates both standard backsets with included hardware but requires the correct tailpiece length for double-cylinder doors.
For users who have already purchased the Secure Pro and are planning self-installation, reviewing the door frame and strike plate condition before installation is worthwhile. A deadbolt is only as strong as the frame it anchors into. A strike plate secured with short screws into the door jamb — the most common residential installation — can be kicked in with a single impact regardless of the lock grade. Replacing the strike plate with a heavy-gauge reinforced model secured with 3-inch screws into the structural framing takes under 30 minutes and meaningfully improves forced-entry resistance at minimal cost.
Existing Secure Pro owners experiencing intermittent fingerprint rejection should first check whether the sensor lens has accumulated residue — a common cause of false rejections that a dry microfiber cloth resolves. If the issue persists, re-enrolling the affected fingerprint using multiple angles during the registration process typically improves recognition rates. The lock allows enrollment of multiple impressions per finger, which is useful for users whose fingerprint condition changes across seasons or due to work-related wear.
For property managers deploying multiple Secure Pro units across rental units, establishing a consistent access log review schedule and setting expiration dates on all guest codes — rather than issuing permanent codes to temporary occupants — significantly reduces credential management risk over time. The app’s access history feature provides a timestamped record of all entry events, which can be relevant documentation in property management disputes or incident investigations.
Anyone considering upgrading the physical security profile of a Secure Pro installation should speak with a locksmith about high-security cylinder retrofit options. Some aftermarket high-security cylinders can be fitted to the Lockly housing, providing pick and bump resistance without replacing the entire lock unit. A locksmith familiar with smart lock hardware can advise on compatible cylinders and whether the modification affects the manufacturer’s warranty terms.
