Best Garden Gate Locks for Security: 2025 Expert Review

Published 16 December 2025

Improving your garden security often starts at the back gate. However, many homeowners struggle with locks that seize up, catches that miss their alignment due to timber movement, or fittings that simply aren't robust enough to withstand forced entry.

In York, where we deal with driving rain and damp conditions, timber gates expand and contract significantly throughout the seasons. This movement can render standard bolts useless if not chosen correctly. A proper gate lock needs to accommodate this movement whilst keeping your property secure.

In this review, I've selected three locking mechanisms suitable for different needs: a budget-friendly hasp and staple, a high-quality long-throw lock for daily use, and a robust solution for thicker gates prone to movement.

Specs vs. The Real World

The Spec: "Weatherproof / Rust-Proof Claims"

The Theory

"Manufacturers often claim 'rust-proof' or 'weather-resistant' finishes will last indefinitely outdoors."

The Reality

In our damp climate, only high-grade stainless steel or brass truly resists corrosion long-term. Powder-coated steel will eventually chip and rust unless regularly inspected and oiled.

The Spec: "Universal Fit"

The Theory

" locks are advertised to fit any wooden gate."

The Reality

Timber thickness varies massively. A standard 50mm lock won't reach through a heavy braced gate. Always check your gate's stile thickness (the vertical timber edge) before buying.

My Top 3 Recommendations

Three options to cover different needs and budgets

Door Lock Gate Bolt & Door Latch Hasp with Padlock

Budget Pick
Door Lock Gate Bolt & Door Latch Hasp with Padlock

MIVITOOM

For a simple, cost-effective solution, this sliding bolt and huge padlock combination does the job. It is ideal for side gates or shed doors where high-tech integration isn't required, offering visual deterrence and basic physical security.

Price£8.99 (at time of writing)
MaterialStainless Steel
Lock TypeSliding Bolt with Padlock
The Good
  • Very affordable complete kit including padlock
  • Simple surface-mounted installation (no complex chiselling)
  • Visual deterrent due to the visible padlock
The Bad
  • Padlocks can be fiddly to operate in wet, freezing weather
  • Surface-mounted screws are generally less secure than a mortice lock

Installer Tip:

Whilst the kit comes with screws, for a garden gate I strongly recommend replacing the main hasp fixing screws with coach bolts that go all the way through the timber. This prevents a burglar from simply prying the screws out with a crowbar.

Long Throw Heavy Duty Gate Lock (50mm)

Quality Choice
Long Throw Heavy Duty Gate Lock (50mm)

SEPOX

This is the style of lock I install most frequently on high-quality timber gates. The 'long throw' bolt shoots further out than a standard lock, helping to bridge large gaps, and the brass cylinder mechanism is reliable. Being able to unlock it from both sides is a massive convenience compared to a padbolt.

Price£29.99 (at time of writing)
Max Gate Thickness50mm
MechanismLong Throw Deadlock with Brass Cylinder
The Good
  • Key access from both sides (great for front access)
  • Brass cylinder resists corrosion better than steel
  • Stainless steel external fixings resist rust
The Bad
  • Requires drilling a 26mm hole accurately through the gate
  • More expensive than basic bolts

Installer Tip:

When drilling the hole for the barrel, drill halfway from one side and then finish from the other side. This prevents the timber from splintering ('blowing out') as the drill bit exits. Also, grease the stainless steel bar inside the lock before fitting.

70mm Big Double Long Throw Gate Lock

Problem Solver
70mm Big Double Long Throw Gate Lock

Concise Home

Standard gate locks often bottom out on thicker bespoke gates, but this unit handles up to 70mm thickness. Crucially, it features an 'elongated keep' which allows for vertical movement—solving the common issue of the latch not lining up when the gate drops slightly over time.

Price£24.99 (at time of writing)
CapacitySuits 70mm (2") thick doors/gates
FeatureElongated Keep
The Good
  • Perfect for extra thick or heavy-duty timber gates
  • Elongated keep accommodates gate sag or seasonal ground movement
  • 6-pin tumbler provides higher security pick-resistance
The Bad
  • Keys are quite long (can be bulky in a pocket)
  • Fixing screws provided could be higher quality

Installer Tip:

The elongated keep is a brilliant feature for heavy timber gates. When fitting the keep to the frame or post, position the bolt hole slightly below the centre point. As all gates eventually drop slightly due to gravity, this gives you maximum room for future movement without needing to refit the lock.

Frequently Asked Questions

What is the best way to maintain a garden gate lock?
Avoid WD-40 as acts as a solvent that eventually strips away grease. Instead, use a graphite powder for the key barrel and a light dab of white lithium grease on the bolt mechanism once a year before winter sets in.
Why has my wooden gate lock stopped lining up?
This is likely due to timber movement. In damp Yorkshire weather, wood swells, and in summer it shrinks. Additionally, heavy gates can 'drop' on their hinges. An adjustable hinge or a lock with an elongated keep (like the Concise Home option above) helps manage this issue.
Are long-throw locks better than padbolts?
Generally, yes. Long-throw locks allows you to open the gate from both sides with a key, which is more convenient than reaching over to slide a bolt. They are also harder to force open as the bolt extends deeper into the frame.
Can I fit a gate lock myself?
Surface-mounted locks (like the budget option) are easy DIY jobs requiring just a screwdriver and drill. Mortice-style or long-throw locks require more precision with spade bits and chisels. If you are unsure, a local joiner can ensure a neat, secure fit.
