Best Gate Lock For Vinyl Fence: Compare 10 Locking Latches

#1 · Best Overall

1. Weatherables Keystone Advantage

• Material: Nylon Polymer
• Weight: 1.3 lb
• Material Type: Nylon Polymer

Best for: Two-sided keyed fence access.

Why it ranks #1: Explicitly fits vinyl gates and provides two-sided keyed access; UV-resistant nylon polymer, stainless steel, and an included marking template support installation.

The Keystone latch provides access from both sides and works with vinyl, wood, and metal gates, so users need not walk around to operate it. Its key-lockable gravity latch also suits buyers who want a locking option alongside self-latching operation, with left- or right-swinging gate compatibility.

Two-sided operation is useful when people approach the gate from either direction, while compatibility with left- and right-swinging gates allows more flexibility in placement. The gravity latch self-latches, and its key-lockable mechanism adds a way to secure the gate. Nylon polymer and stainless steel are specified for the construction; Weatherables also describes resistance to intense weather changes, including temperature, water, humidity, and sun exposure. The included marking template, instructions, and fasteners support installation.

Skip it if you want code entry instead of a key-lockable latch; Yardlock's Gate Lock uses a personal code.

This fits buyers who want keyed security and access from both sides of a vinyl, wood, or metal gate. Its swing-direction flexibility is useful, but choose a different style if code entry or a basic non-keyed latch is the priority.

#2 · Best Keyless Option

2. Yardlock Code Lock

• Material: Zinc
• Weight: 0.79 kg
• Material Type: Zinc

Best for: Keyless code-entry vinyl gates.

Why it ranks #2: The listing specifically says it installs on vinyl gates and works with inward or outward swings; a personal code replaces a key.

A personal-code box opens the Yardlock without a key, while a wire inside lifts the latch on the opposite side. That arrangement gives visitors keyless access from outside and lets someone inside raise the latch without entering the code, for wood or vinyl gates that swing either way.

The code-operated box keeps entry dependent on a personal code, and the internal wire transfers that release to the latch across the gate. This lets the outside user unlock without carrying a key while preserving a simple lift-to-open action from inside. Yardlock lists compatibility with wood and vinyl gates and with inward- or outward-swinging gates, offering useful placement flexibility. Its zinc construction and keyless operation make this a different choice from conventional keyed latches; the supplied dimensions describe the lock body and parts.

Skip it if you want keyed access or a two-sided keyed latch; Weatherables Keystone offers a key-lockable option.

Choose this for a vinyl or wood gate where code-based outside entry and straightforward inside release suit the household. Its fit covers either swing direction, but it is not the choice for buyers who specifically want key-operated access.

#3 · Widest Gap Range

3. National Hardware LokkLatch

• Material: Plastic
• Weight: 4.32 oz
• Material Type: Plastic

Best for: Adjustable keyed gate security.

Why it ranks #3: Works with vinyl and offers keyed outside access with inside push-button release; its listed gate-gap capacity reaches 4-9/16 inches.

An adjustable fit for gaps up to 4-9/16 inches distinguishes the National Hardware LokkLatch, helping accommodate gates that do not sit at one fixed spacing. Keyed outside access and a push-button inside release pair that fit flexibility with a clear entry and exit routine.

Horizontal and vertical adjustments let this latch accommodate gate gaps up to 4-9/16 inches, which can help when aligning a wood, metal, vinyl, or composite gate. From outside, access is keyed; from inside, a push-button release avoids requiring a key for exit. The listing positions it for outdoor use and pool-gate security, making the two-sided operating method relevant to controlled access. Its plastic construction keeps the latch light, though the supplied facts do not specify a weather-resistance rating.

Skip it if you need a weather-resistance specification; D&D Technologies LL3AL explicitly lists weather resistance.

Choose this for a vinyl or other listed fence when gap adjustment and keyed outside access matter. The push-button interior release is practical for regular passage; buyers prioritizing an expressly weather-resistant polymer latch may prefer another option.

#4 · Best One-Side Key Lock

4. D&D LokkLatch LL3AL

• Material: Polymer
• Weight: 0.29 kg
• Material Type: Polymer

Best for: Single-sided keyed gate control.

Why it ranks #4: Designed for vinyl gates and key locking from one side; listed for posts 1 to 6 inches deep and gaps from 3/8 to 1-1/4 inches.

The D&D LL3AL locks and operates from only one side, providing a clear choice for buyers who want controlled access from a designated approach. It is listed for square-frame-post metal, wood, and vinyl gates, with stated post-depth and gate-gap ranges to help assess installation fit.

A key-lockable mechanism on one side gives the gate a defined access point, which can suit installations where operation from the other side is not needed. The listed post depth range is 1 to 6 inches, and the gap variance is 3/8 to 1-1/4 inches, providing dimensions to compare with the gate setup. Its industrial-strength polymer construction is described as weather resistant, and the manufacturer says the latch will not rust or stain. The listing covers metal, wood, and vinyl gates.

Skip it if you need key access from both sides; Weatherables Keystone provides two-sided access with a key-lockable latch.

This is a fit for buyers who want keyed control from one designated side of a square-post vinyl, wood, or metal gate. Check the stated post and gap ranges, and choose a two-sided model if both approaches need access.

#5

5. SANKINS Keyed Double-Sided Latch

• Weight: 12 oz

Best for: Keyed access from either approach.

Why it ranks #5: Its listing names vinyl gates and describes key unlocking from indoors or outdoors, though it also clarifies this is a one-way lock.

The SANKINS keyed latch can be installed on either the inside or outside of the gate, allowing family and guests to unlock from either approach. Its polymer and stainless-steel construction is listed alongside compatibility with wood, vinyl, metal, and square-post gates.

Installation on either side lets the buyer choose which approach receives the keyed unlocking operation, while the listing describes access for people entering and exiting from both indoors and outdoors. The product is explicitly a one-way lock, however, and does not provide two-way opening unless using a model with a pull cord. Polymer and stainless steel are specified, and the listed applications include wooden fences, outdoor gates, double doors, and pool gates. This makes the one-way operating detail important to household traffic planning.

Skip it if you need two-way opening without a pull cord; Weatherables Keystone offers access from both sides.

Choose this for a wood, vinyl, or metal gate when keyed access from either approach and flexible installation side fit your layout. Its one-way operation is the key boundary; households needing two-way opening should select a suitable alternative.

#6 · Best Steel Gravity Latch

6. HILLMASTER Gravity Latch 666

• Material: Steel
• Weight: 11.7 oz

Best for: Gravity latch for wider gaps.

Why it ranks #6: Explicitly lists vinyl fence compatibility and supports inward or outward swings; steel construction has a black powder coat and zinc plating.

A self-latching design that accommodates a gate-to-post gap up to 1-9/16 inches makes the HILLMASTER a practical candidate for a wider-spaced installation. Its fingertip release can also be operated with a wire, while the latch supports inward- and outward-swinging gates and doors.

The listed gap capacity of up to 1-9/16 inches helps buyers assess whether the latch can bridge their gate and post spacing. Gravity self-latching closes the gate with its movement, while the fingertip release provides a manual opening method and can also be operated with a wire. Heavy-gauge steel, a black powder-coated finish, and zinc plating are specified for corrosion resistance. The product is listed for wood, metal, and vinyl gates, making it relevant to a range of fence materials.

Skip it if you require keyed access; National Hardware LokkLatch provides keyed outside access and an inside push-button release.

Pick this for a wood, metal, or vinyl gate when automatic gravity latching and a wider listed gap capacity matter. Its wire-operated release adds flexibility, but buyers needing keyed security should choose a keyed model instead.

#7

7. D&D LokkLatch LL3ABL

• Material: Polymer
• Weight: 0.36 kg
• Material Type: Polymer

Best for: Independent two-side lock control.

Why it ranks #7: The listing gives a useful post-depth range of 1 to 6 inches and gap range of 3/8 to 1-1/4 inches, but does not explicitly name vinyl compatibility.

Separate locks for the External Access Button and Main Latch give the D&D LokkLatch distinct control points on the gate. Its listed post depth range of 1 to 6 inches and gate-to-post gap range of 3/8 to 1-1/4 inches help buyers assess installation fit before choosing it.

The specified post depth range of 1 to 6 inches and gap variance of 3/8 to 1-1/4 inches provide concrete dimensions for checking a square-post installation. The External Access Button locks separately from the Main Latch, so operating one lock does not automatically lock the other; the Main Latch, when locked, cannot be unlocked and opened as described. Polymer construction and 316 marine-grade stainless-steel components are listed, while the manufacturer says the latch will not rust or stain.

Skip it if you prefer a single-sided keyed latch; D&D Technologies LL3AL operates and locks from only one side.

This suits buyers who want separate control of the access button and main latch on a square-post gate. Check the stated post-depth and gap ranges against the installation; its dual-control arrangement is less direct than a single lock.

#8

8. HILLMASTER Heavy-Duty Latch

• Material: Alloy Steel
• Weight: 0.76 kg
• Material Type: Alloy Steel

Best for: Pull-string gravity latch users.

Why it ranks #8: Its description explicitly includes vinyl fences and inward or outward swinging gates; alloy-steel construction and a self-latching release suit gravity-latch use.

A pull string can operate the HILLMASTER’s self-latching fingertip release, giving users an alternate way to open the gate. Its heavy-gauge alloy-steel construction and support for inward- and outward-swinging gates make it an option for buyers seeking automatic latching across either swing direction.

Gravity self-latching lets the latch engage as the gate closes, while the fingertip release or pull string provides two listed ways to open it. That release choice can suit a gate where reaching the latch directly is inconvenient. The alloy-steel construction weighs about 0.76 kg, and the listing describes a black powder-coated finish with zinc-plated corrosion resistance. It is intended for inward- or outward-swinging gates and doors; the supplied facts do not give a gate-gap range.

Skip it if you need a stated wide-gap limit before selecting hardware; HILLMASTER model 666 specifies a gap up to 1-9/16 inches.

This suits buyers seeking an automatic gravity latch with a pull-string option for a wood, metal, or vinyl fence gate. Its swing-direction flexibility is useful, but the supplied information does not state a gap capacity to check against your installation.

#9

9. BORDERSMOVER Automatic Latch

• Material: Alloy Steel
• Material Type: Alloy Steel

Best for: Spring-latch padlock option.

Why it ranks #9: Listed for wooden and vinyl fences, this steel self-closing latch accepts a padlock; the listing gives a 0.3-inch hole diameter.

A spring-loaded self-closing action lets this BORDERSMOVER latch engage when the gate is pushed shut, with a fingertip press to open it from the other side. Its padlock hole measures up to 0.3 inches in diameter, giving buyers a specific constraint when selecting a lock.

The self-latching design closes with a slight push, which can simplify routine passage through a wood or vinyl gate. On the opposite side, a light fingertip press opens the latch; the spring and adjustable screw are listed as part of its mechanism. Steel construction and a powder-coated finish are specified for weather suitability, while the padlock hole provides an added locking option. The package lists self-drilling screws and a nylon spacer, supporting screw-in installation; no gap range is supplied.

Skip it if you need a stated gap limit; HILLMASTER model 666 specifies compatibility with gaps up to 1-9/16 inches.

This suits buyers of wood or vinyl gates who want self-closing action, fingertip release, and an optional padlock. The 0.3-inch hole limit matters when choosing a padlock, and the listed information does not specify gap capacity.

#10

10. SANKINS Self-Locking Latch

• Material: Alloy Steel
• Weight: 0.76 kg
• Material Type: Alloy Steel

Best for: Padlock-ready wood gate users.

Why it ranks #10: The product description focuses on wood or metal doors rather than vinyl, making its use-case fit less explicit despite its gravity locking and included mounting hardware.

A standard-size padlock can be added to this SANKINS self-locking latch, giving buyers a way to secure a gate beyond its automatic gravity action. Thick steel construction and inward- or outward-swinging compatibility make it a useful option for wood or metal gates around yards and gardens.

The gravity mechanism self-latches when the gate closes, while a fingertip release provides a direct way to open it. The latch is designed to accept a standard-size padlock, so buyers can add lockable access control using their own padlock. Its alloy-steel construction and included mounting hardware and fasteners support a sturdy, ready-to-install setup. The supplied facts list wood or metal doors and outdoor gates; they do not specify vinyl compatibility or a gate-gap range.

Skip it if you need a vinyl-specific listed fit; D&D Technologies LL3AL names vinyl gates and offers key locking.

Choose this for a wood or metal gate when automatic latching and the option to add a padlock meet your needs. Its listed compatibility does not include vinyl, so buyers with a vinyl gate should select a model that names that material.
