Situations
A side gate can be improved for a few dollars, and the common mistake is buying a good padlock for a gate that lifts straight off its hinges. Secure one hinge, bolt the hasp properly, use a shrouded lock, know when somebody comes through, and light the passage.
Side gates are where people get into backyards, and they are often protected by hardware chosen at a checkout.
Two pin hinges mean the gate lifts off. Secure one of them and the lock at the other end starts to matter. It is often the one people forget.
Coach bolts, through, nuts inside. Screws into the outside face of a gate are a formality.
Shrouded, so a cropper has nowhere to sit. Buy the shortest shackle that will physically reach — every millimeter of exposed steel is attack surface. The ABUS in this guide is the 63 mm (2.5 in) long-shackle version: only take it if the hasp needs it. On an outer gate taking driving rain, a corrosion-resistant body matters more than an extra millimeter of shackle, because a seized padlock is one nobody uses.
A driveway or passage alarm with the sensor outside and the receiver indoors tells you somebody has come through, which a lock never does. Aim it across the passage rather than along it.
A motion floodlight over a side passage acts first, before anybody touches anything. Aim it down rather than out, and check what it lights from the neighbor’s window.
Usually a shed, a bike and a back door. Secure those too.
Where a gate removes the concealed route to the back of a house, which is the classic approach.
Where a gate protects tools, bikes and the back door together.
Where a locked gate signals that going further is a deliberate act rather than a casual one.
Where a locked gate complicates parcels, which is worth planning for rather than discovering.
| The weakness | The fix | The note |
|---|---|---|
| Low gate | Height or a trellis top | Climbability decides everything |
| Bolt reachable over the top | A lock lower down | Position matters |
| Liftable hinges | Hinge bolts | Otherwise the gate comes off |
| Rotten post | Replace the post | The gate is only as good as it |
Gates move with the weather and the ground, and a gate that has dropped no longer meets its latch. That is usually why gates end up propped open or left unlocked, which is a security failure caused by maintenance rather than design.
A gate is a barrier for everyone, including you.
60 mm (2.36 in) cast-iron monoblock body · chrome-plated hardened bolt · shrouded shackle
A monoblock cast-iron padlock: the body encloses the shackle so that very little of it is exposed. KOTARBAU states a chrome-plated hardened steel bolt in a solid cast body.
Best for: A shed, a store or a gate where a cropper is the realistic threat rather than a curious hand.

6.5 mm (0.26 in) shackle · 63 mm (2.48 in) high shackle · Titalium body, 107 g (3.8 oz) · paracentric key · ABUS level 5
ABUS's everyday Titalium padlock with a high 63 mm (2.48 in) shackle: a special-aluminum body at 107 grams, a hardened steel shackle, a paracentric keyway against manipulation, and double shackle locking.
Best for: Doors, lockers and tool boxes where the lock is carried, opened often, and left outdoors between times.
≈ $28
Split sensor and receiver · 32 tones · 8 m (26 ft) × 110° PIR · wireless chime alarm
A two-part driveway alarm: a PIR sensor outside and a receiver indoors with 32 selectable tones. TECKNET states an 8 meter (26.2 ft) by 110 degree detection field.
Best for: Knowing somebody has entered a driveway or a yard before they reach the door.
20 W · 2,200 lm · 6500 K · IP66 · adjustable SENS, TIME and LUX
A 20 W motion floodlight at 2,200 lumens and 6500 K, rated IP66, with three separate adjustments: sensitivity, on-time and the ambient light level below which it will trigger.
Best for: A first security light where the three adjustment dials matter more than the brand.
Because a gate on ordinary pin hinges lifts vertically off them with the lock still engaged at the other side. Securing one hinge — a hinge bolt, a reversed pin, or a plate that fouls the lift — is what makes the lock relevant at all.
Coach bolts through the timber with the nuts on the inside. Screws driven into the outside face of a gate are removed with the same screwdriver anybody carries, whatever lock hangs from them.
High enough not to be stepped over, and without footholds. Height is the main thing that turns a gate from a formality into a barrier.
Low enough that an arm reaching over the top cannot operate it. A reachable bolt secures nothing at all.
Some people deliberately do not, since noise is a modest alarm. It is a genuine trade-off between annoyance and warning.
Anti-climb measures raise real liability questions in many countries. Check what is permitted before fitting anything that could injure.
A locked side gate changes where parcels go. Deciding that in advance is easier than discovering a courier has left one in the street.
Designed for: A shed, a store or a gate where a cropper is the realistic threat rather than a curious hand.
Its main asset: Monoblock construction shrouds the shackle — the single biggest step up in this family
Its main gap: Heavy, and it will mark a painted gate
Designed for: Doors, lockers and tool boxes where the lock is carried, opened often, and left outdoors between times.
Its main asset: 107 g (3.8 oz) — light enough to carry without noticing
Its main gap: 6.5 mm (0.26 in) shackle, thinner than the Alutitan alongside it
Designed for: Knowing somebody has entered a driveway or a yard before they reach the door.
Its main asset: Sensor outside, sound inside — you hear it, the visitor does not
Its main gap: Range depends on the axis: 8 m by 110° horizontally, 10 m by 30° vertically
Designed for: A first security light where the three adjustment dials matter more than the brand.
Its main asset: Three separate adjustments — sensitivity, time and daylight threshold
Its main gap: 6500 K is a harsh, blue-white light that neighbors notice
