Gate Lock Installation
Gates move with the weather, so the lock that survives here is the one with room to be slightly out of line.

A gate lock lives outdoors with no shelter, mounted on a structure that moves. Timber swells when it is wet and shrinks when it dries, posts shift as the ground does, and a gate that latches sweetly in one season can miss its keeper entirely in another. Front door hardware fails out here not because it is weak but because it has no tolerance for that movement.
The second constraint is that a gate is usually the lock nobody ever services. No shelter, no maintenance, and often no key touched for months until the afternoon somebody actually needs to get through it. Generous tolerance and a cylinder that can be replaced on its own matter far more here than a high grade on a specification sheet.
What is assessed at the gate
- How much the gate moves through its swing. One that has to be lifted or shouldered to meet the post needs the hinges and the post sorted out before any lock is chosen for it.
- Post condition. A latch is only as good as what it screws into, and a post that rocks when you push it will pull its fixings loose inside a season.
- Frame material — timber, tubular steel, or a wrought pattern with nowhere flat to mount anything. Metal gates usually want a weldable box or a bolt-through plate rather than wood screws.
- Whether it must be operable from both sides, and by whom. A keyway on the inside face of a gate that sits on an escape route is a hazard rather than extra security.
- Whether a pool or a small child is behind it, because a gate enclosing a pool carries self-closing and self-latching requirements and a latch height set by rule rather than by preference.
Know these before hardware is picked
- Whether the gate is timber, metal or a composite panel, and whether it is solid or open framed.
- Whether anyone outside the household needs to open it, such as a delivery or a meter reading.
- Whether the gate currently drags on the ground, sags at the latch side, or has to be forced to close.
- Whether power reaches anywhere near the gate, if you are considering anything electric.
- Whether the gate forms part of a pool enclosure or a shared access route to another property.
If this is a powered vehicle gate running on an operator, the lock is the smallest part of it and the control side has to be designed together with the gate. see commercial lock installation.
Common questions
What kind of lock survives outdoors best?
Something with a shielded cylinder and a mechanism that has room to move. A shrouded shackle padlock on a heavy hasp is unglamorous and lasts, because the working parts sit behind metal and the whole unit can be swapped without touching the gate. Fine tolerance hardware is what seizes first out there.
My gate latches in winter and not in summer.
That is timber moving, and it tells you the latch was set with no margin to begin with. The answer is either a latch with a wider catch, a keeper you can adjust between seasons, or dealing with the sag that ate the margin in the first place.
Can the gate go on my house key?
Only where the gate hardware takes a cylinder on a compatible keyway, which many outdoor latches simply do not. Where it can be matched it is worth doing, because a gate key that lives in a kitchen drawer is a gate that gradually stops being used.
Should I worry about someone reaching over the top?
Yes, and it is the most common way a gate lock is beaten — a hand over the rail to the thumbturn or the release on the inside face. A shielded latch, a solid top rail, or moving the release lower and further in all deal with it, and none of them involve buying a stronger lock.
