Mechanical Lock Buying Guide: Choose the Right Lockey Lock
At GateSecurityHardware, we specialize in providing trusted, secure solutions for access control, whether you're locking up a storefront, securing a backyard gate, or upgrading interior door security. One of the brands we trust most is Lockey. Their mechanical keyless locks are known for durability, reliability, and ease of use across residential, commercial, and industrial settings. We've worked with Lockey for years and proudly offer their full line of mechanical locks designed for doors, gates, cabinets, and more.
But we also know that picking the right lock can feel overwhelming. With so many styles, functions, and configurations, it's not always obvious what features you need until you're staring at a list of unfamiliar options. That's why we created this guide, to walk you through everything you need to know to confidently choose the right mechanical lock for your project.
Key Factors to Consider Before Buying a Mechanical Lock
Before you dive into models and specs, it's important to think about how your lock needs to perform. Here are the most important factors to keep in mind:
- Handle Style: Choose between knobs, levers, or thumb-turns based on preference, ADA requirements, and ease of use.
- Compliance: If your lock is installed in a public or commercial space, ADA compliance may be mandatory.
- Lock Configuration: Decide if you need single-sided access, a double-sided keypad, passage mode, or a key override option.
- Latch Type: Depending on whether you're installing the lock on a gate, sliding door, or standard door, you'll need a compatible latch style like a deadbolt, spring latch, hookbolt, or cam.
- Finish Options: Consider aesthetics and environmental resistance, Lockey offers marine-grade finishes for harsh outdoor use.
- Application Type: Is your lock going on an interior office door, an exterior gate, a sliding glass patio door, or a supply cabinet?
- Installation Style: Will the lock be surface-mounted, mortised into the door, or installed using a gate box?
Now that you know what to consider, the next section walks you through each feature in detail, from lock mechanics to latch types to code access, so you can better understand how these options align with your specific needs. After that, we'll explore Lockey's most popular mechanical lock series and help you match the right model to your project.
Types of Lockey Mechanical Locks by Handle Style
Lockey offers a wide range of mechanical keyless locks to suit every application, from residential entry doors to commercial gates and aluminum storefronts. One of the most important factors in choosing the right lock is understanding the handle type. Each handle style offers unique functionality and is better suited for specific types of installations. Below are the main handle interface options available in Lockey's mechanical lock lineup.
Knob Locks
Traditional and compact, knob-style mechanical locks are ideal for homes and light commercial use for simple turn-and-go function.
Lever Handle Locks
ADA-compliant and ergonomic, these locks are perfect for commercial buildings and high-traffic areas requiring easy one-handed operation.
Thumb-Turn Locks
Simple and low-profile, thumb-turn mechanical gate locks are great for gates, sheds, and enclosures where external handles aren't required.
Cam Locks
Designed for cabinets, lockers, and enclosures, Lockey cam locks are compact, secure, and offer mechanical code access in tight spaces.
Lockey Mechanical Lock Configurations and How They Work
While Lockey's mechanical locks all operate without electricity or batteries, they come in several different configurations that affect how you interact with them. Whether you're installing a gate lock, a door lock, or a cabinet lock, understanding how each lock functions will help you choose the right model for your needs. Below, we explain the most common mechanical input methods and access features found across the Lockey product line.
Combination Dial Locks
Certain Lockey cam locks and specialty enclosure models use a combination dial system. Instead of pressing buttons, you twist a series of rotating dials to line up the correct sequence. Once aligned, the mechanism unlocks. These are ideal for compact applications like cabinets, lockers, and utility enclosures where a low-profile and silent solution is needed.
How does it work?
Combination dial locks operate by turning a rotating dial in a specific sequence to align internal components. These locks are fully mechanical and require no power source, making them ideal for low-maintenance security in various applications like gates, cabinets, and lockers.
- Turn the dial left and right following the preset numeric code.
- Each number aligns a separate internal cam or disc.
- When the full combination is dialed correctly, the locking mechanism disengages.
- The user turns a thumb-turn or handle to retract the latch or bolt.
Push-Button Mechanical Locks
Most Lockey models use a mechanical push-button keypad. These locks are set to a static, user-defined code during installation by configuring internal pins or discs. To unlock, the correct sequence is entered, followed by a turn of the lever, knob, or thumb-turn. These models are widely used for gates, doors, garages, and commercial entrances where durable, no-fuss access is essential.
How does it work?
Push-button locks use a physical keypad with a pre-set or user-defined numeric code. These locks unlock by aligning internal tumblers through the correct sequence of button presses, offering fast access without a key or dial.
- Press the correct sequence of buttons on the keypad (e.g., 1-3-5-7).
- Each press shifts internal pins or cams into alignment.
- Once the full code is entered, the lock disengages automatically.
- The user opens the door by turning a knob, lever, or thumb-turn.
Single-Sided vs Double-Sided Keypad Access
Single-sided locks feature a keypad on one side only, usually the exterior. The opposite side is left open, using a knob, lever, or thumb-turn for easy exit. This design is common for doors or gates where you only need to control access in one direction, like entering a backyard or an office suite.
Double-sided locks include keypads on both the entry and exit sides. These are ideal for perimeter gates, secure facilities, or areas where you want to restrict access from both directions. They require a code to both enter and exit, adding an extra layer of security for sensitive or high-traffic zones.
Passage Function
Some Lockey locks include a built-in passage mode. When enabled, the latch stays retracted, allowing the door or gate to open freely without entering a code. This feature is useful during high-traffic periods or when access needs to remain open temporarily. The passage mode can usually be turned on or off with a toggle pin inside the lock housing.
Key Override Options
Although Lockey locks are designed to operate entirely without keys, several models offer an optional key override for added peace of mind. This feature lets you use a physical key as a backup in case someone forgets the combination or the lock needs to be accessed quickly by authorized personnel.
Key override locks are available in two main formats:
- Keyed Alike: Multiple locks use the same key. Ideal for property managers or maintenance crews who want to carry one master key for all locks.
- Keyed Different: Each lock comes with a unique key. Best for situations where individual key control is important and you want to prevent cross-access between users.
Types of Lockey Latches and Locking Mechanisms
Cam Lock
Cam locks use a rotating metal arm (the "cam") to secure cabinet doors, lockers, or enclosures. Turning the cam moves it behind a fixed catch, locking the compartment shut.
Deadbolt
A deadbolt uses a thick, solid metal bolt that manually extends into the door frame for maximum holding strength. Ideal for doors requiring high security and no spring-loaded action.
Deadlocking Spring Latch
Also known as a latchbolt, this type automatically latches when the door closes and includes a deadlocking plunger to prevent tampering or “loiding.” Great for entry doors with frequent use.
Slide Bolt (Deadbolt Style)
These manual bolt locks slide horizontally or vertically into place. Common on gates and pool enclosures, they provide solid physical security and simple locking action.
Hook Bolt
Hook bolts curve into the strike plate to provide strong resistance against pull-force. Ideal for sliding gates, glass doors, or applications where vertical motion isn't used.
