Gate & Building Entry Locks in Epsom
A neighbour mentions, in passing, that the key from three tenants ago still lets him into the building's front door. Nobody changed it after he moved out, and now the property manager wants to know exactly how many keys are still floating around out there.
Gate & Building Entry Locks
In plain words
A building outlives its tenants, and every move-out that skips a rekey leaves one more key in circulation that nobody living there today can account for. This service treats that turnover as routine business: the shared entry's cylinder is rekeyed to a fresh combination, new keys are cut for everyone who currently needs one, and any gate on the same property that should share that key is brought along to match. What used to be an open question about who can get in becomes a short, current list.
How the visit goesBetween the front gate, the side gate and the one behind the shed, there are three different padlocks, three different keys, and a growing pile of duplicates in a kitchen drawer that nobody can match to the right lock anymore.

How the visit goes
Identifying the hardware family
Every lock on a gate or shared entry belongs to a family with its own habits: a surface-mounted gate lock, a mortise case built into a heavier door, a rim cylinder feeding an electric strike, or a panic device on a fire exit. The maker's mark, the keyway shape and whether a thumb-turn or a second keyed side is present all point to which family sits on the door. Getting this right before opening anything up is what lets the visit move straight to adjustment or replacement instead of guessing at parts that will not fit the housing already there.
Working on the cylinder itself
Depending on what the assessment found, the cylinder is either rekeyed, replaced with a weather-rated unit, or decoded so a fresh key can be cut to match it. Rekeying removes the existing pin combination and sets a new one, so old keys stop working while the same housing stays on the gate. A full replacement suits a housing that is worn, pitted or the wrong grade for outdoor use. Either way, the new or updated cylinder is cycled repeatedly with the new key, from both sides where the hardware has two, before it is considered finished.
An electronic entry tested as one system
Where the entry includes a buzzer, keypad or electric strike, you see it worked before the locksmith leaves: the intercom releasing the door on a buzz, the keypad accepting a code, and, where the installed lock includes one, the mechanical override key turning cleanly as a backup. Batteries or settings that were touched during the visit are confirmed, and, if a backup key exists, you are shown where it lives so it is not lost track of. An entry with both a working backup key and working electronics now has two independent ways to open it, worth keeping in mind the day the power or the app misbehaves.

What affects the quote
Same fees day, night or weekend
1Whether the post or frame needs correction
When the underlying cause is a leaning post or a shifted frame rather than the lock itself, resetting, packing or bracing that structure is quoted as its own item alongside the lock work.
2Weather-rated versus standard hardware
Hardware built and sealed for outdoor exposure differs from standard indoor-grade hardware, and choosing the weather-rated option for anything mounted outside is reflected in the parts portion of the quote.
3Condition of the closer, hinges and post
Simple adjustment of an existing closer is a smaller job than replacing a worn closer, correcting sagging hinges, or resetting a post that has shifted with the ground; the quote follows whichever combination the assessment finds.
Gate & Building Entry Locks: questions
Does this service cover the gate itself, or only the lock?
Both, where the two are connected, which on a gate they usually are. A locksmith working on a gate lock also looks at the hinges, the post and the closer, since a lock rarely fails on its own when the real cause is a sagging gate or a post that has shifted. Work that goes beyond hardware the locksmith carries, such as rebuilding a rotted post or a damaged fence panel, is flagged so it can be handled by whoever normally does that kind of repair.
What is the difference between a gate lock and a regular door lock?
A gate lock is built to work outdoors, so it usually pairs a latch or bolt with a closer that swings the gate shut on its own using its own spring, rather than relying on a person to push it home. The cylinder tends to be weather-rated, and the whole assembly fits a gate frame or post rather than a conventional door jamb. A building entry door, by contrast, often combines this outdoor hardware with an interior-style latch or an electric strike.
What information over the phone helps identify the hardware before the visit?
A photo of the lock, the gate or the entry door, taken from a few steps back and up close on the cylinder, tells the locksmith more than a verbal description usually can. Mentioning whether the gate is wood, metal or vinyl, roughly how the property is laid out, and whether the entry has any buzzer, keypad or electric component narrows down what hardware and parts to bring. None of this is required, but it does shape what shows up in the van.
