Why won't my gate lock, and what usually causes it?
A gate that won't lock is a different problem from a door that won't lock. A door sits inside a frame and closes against a stop. A gate hangs on two hinges, swings in the wind, gets pushed by delivery drivers and kids, gets bumped by cars, and stands outdoors every day of the year. After enough years, something moves, and the lock stops lining up with the part it is supposed to catch.
Most gate lock calls come down to a short list of causes. Knowing which one you have is half the repair, and it is the first thing we look at.
In Gardena, the climate is on your side more than most places. The city sits on the inland coastal plain, so you get marine layer overcast but very little direct salt exposure. That means the usual culprit is not coastal corrosion. It is ordinary wear, plus the damp-morning swelling that can make a wooden gate or frame stick until the afternoon dries it out. If your gate latches fine at noon but not at 7 a.m., swelling is a likely suspect.
- A sagging gate: the hinges have loosened or the post has shifted, so the latch bolt no longer meets the strike plate.
- A misaligned latch or strike: even a small drop in the gate leaves the bolt hitting the edge of the plate instead of entering it.
- A worn or gummed-up lock cylinder: dust, grit and dried lubricant make the key hard to turn or stop it from fully retracting the bolt.
- A key that turns but does nothing: usually a broken internal part or a bolt that has jammed against a misaligned strike.
- A keypad lock that has stopped responding: dead batteries, worn buttons, or an internal fault.
- An electronic gate lock or electric strike that no longer releases: a power, wiring or controller problem rather than a mechanical one.
- A bent latch from a gate that slams: repeated impact eventually deforms the hardware.
- Rust or paint buildup on steel hardware that was never maintained.
How do we repair a gate lock, step by step?
We treat the gate and the lock as one system. Replacing a lock on a gate that has dropped half an inch just produces a new lock that fails the same way. Here is how a typical visit goes.
- You call (213) 577-1366, which is answered around the clock. Tell us what the gate is made of (wood, wrought iron, aluminum, chain link), whether it is a side gate, pedestrian gate or driveway gate, what kind of lock is on it, and what it is doing. A photo helps if you can send one.
- We come to you in a mobile van. A gate lock cannot be brought to a shop, so the work happens on site.
- We inspect the gate before we touch the lock: hinges, post, swing, how it closes, and where the latch bolt meets the strike.
- We tell you what we found and what your options are, including the lighter-cost route and the more complete one, and what drives the cost, before work starts.
- We make the repair. That might mean adjusting or relocating the strike, tightening or resetting hinges, cleaning and lubricating the lock with something suited to outdoor use, replacing worn internal parts, or rekeying.
- If the lock is past saving, we install a replacement rated for outdoor use and matched to your gate.
- We test it properly: closing the gate from both sides, opening it with the key or code, and repeating the cycle several times. We also check that you can always get out from the inside, then hand over keys or codes.

Call (213) 577-1366Should I repair the gate latch or replace the whole gate lock?
Gate latch repair is usually the more economical route when the lock body is sound and the real problem is alignment, a worn part, or a seized cylinder. We would rather fix a lock that is fixable than sell you a new one.
Gate lock replacement makes more sense in other situations, and we will say so plainly when we see them.
- The lock is an indoor-rated hardware-store lock that was never meant to live outside and has corroded or seized internally.
- Parts for an older model are no longer available, or the repair would cost more in effort than a new lock.
- The bolt is too short or too weak for the gate, so the gate rattles loose in the latch even when aligned.
- You have lost keys, a tenant has moved out, or you simply do not know who has copies, and rekeying is not enough because the hardware is already worn out.
- You want to move from a key to a keypad, or add a smart or electronic gate lock, which is an installation rather than a repair.
- The gate is used heavily by many people and the existing lock simply was not built for that.
What about keypad, electronic and smart gate lock installation?
Keypad gate locks are popular for good reason: no keys to lose, and you can change the code when a tenant, contractor or house-sitter no longer needs access. But outdoor keypads are not all equal. A weather-resistant gate lock is built with sealed internals and a finish that tolerates moisture and sun. A lock designed for an interior door is not.
There are two broad families. Mechanical keypad locks use button combinations and need no batteries or power, which makes them forgiving on a side gate where nobody wants to climb a ladder to swap cells. Electronic gate locks run on batteries or a wired power source and offer more features, such as multiple user codes, but they depend on that power staying alive.
Smart gate lock installation adds app control or remote access. It can be a good fit, but only if the gate itself closes reliably, the signal reaches the gate, and the lock is rated for outdoor exposure. We will tell you honestly if your gate is not yet ready for it, usually because it does not swing shut on its own. If you are also thinking about the house door, our smart lock installation page covers that separately.
For properties where many people need different access, such as a shared pedestrian entrance at a small complex, a simple keypad can become awkward. That is when a proper access control installation with individual credentials may be the better answer.

Call (213) 577-1366How are driveway, pedestrian and side gate locks different?
Each type of gate has its own habits, and each fails in its own way.
Side gate locks are the most common call. They are typically on a wooden or metal gate between the front and back yard. They are used daily, slammed often, and usually have a basic latch with a lock added later. Alignment and latch condition are the main issues.
A pedestrian gate lock sees heavier use, especially at multi-unit properties, and usually needs a self-closing hinge so the gate latches every time without anyone having to think about it. If the gate does not close fully on its own, no lock will protect it consistently.
A driveway gate lock is a bigger piece of hardware. Swing gates often use drop bolts, gravity latches, or electric locks. Sliding gates use hook bolts or locking points tied to the operator. We repair and replace the locking hardware. If the real fault is the motor, the opener or its control board rather than the lock, we will tell you that plainly rather than guess, so you are not paying for the wrong repair.
For the door locks on the house itself, see our lock repair service. This page stays focused on gates.
What affects the cost of gate lock repair?
We do not quote numbers in a web page because a gate lock job can be very small or quite involved, and the honest answer depends on what is in front of us. These are the factors that actually move the cost, so you can see where a quote comes from.
- Whether the problem is the lock, the latch, the alignment, or all three. Adjusting a strike is a different job from replacing a lock and resetting a hinge.
- Gate material. Wood, wrought iron, aluminum and chain link each need different fasteners, drilling and mounting methods.
- The type of lock. A basic outdoor latch, a mechanical keypad, an electronic gate lock and a smart gate lock sit in very different places.
- Hardware grade. Heavier, weather-resistant hardware costs more up front and usually lasts longer under daily outdoor use.
- Wiring or power. Electric locks and strikes may involve checking or adding power, which adds work.
- Whether we need to rekey, add keys, or reset codes.
- Time of day and how far we travel. We answer around the clock, and you will hear how that applies to your visit when you call.
- Whether the gate itself needs repair. A gate that has dropped may need hinge work before any lock will behave.

Call (213) 577-1366Why call Wilshire Lock & Key for a gated property?
If you need a locksmith for a gated property, a few things about how we operate are worth knowing.
We have been in business since 1987. We have a storefront at 10740 Wilshire Blvd in Westwood and run mobile service vans, so the person who answers the phone works for the same company that shows up at your gate. There is no dispatch middleman reselling your call to whoever is closest. David, the owner and lead technician, oversees the work.
Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round. Gates do not pick convenient times to fail. They fail on a Sunday night or just before you leave for work, and that is when you most want a real person to pick up. Our mobile locksmith service is built for exactly that kind of on-site work.
One more thing worth saying: California requires locksmith companies to hold a Bureau of Security and Investigative Services (BSIS) locksmith company license, known as an LCO license. Ask any locksmith you are considering for their license number before they start work. It is a fair question and a good company will not mind it.
What does gate lock service look like around Gardena?
Gardena grew out of the farming districts of Moneta and Strawberry Park and is now largely built out with 1940s and 1950s single-family tracts, garden apartments and condo complexes. It also has a high share of small multi-unit rental properties. Whether you are in 90247, 90248 or 90249, gate hardware tends to fall into a few patterns.
In residential areas such as Moneta, Strawberry Park and Hollypark, side gates and rear-yard gates are the usual jobs. If your tract home dates to that era, the side gate latch may be well past its original service life. Many Hollypark homeowners call us for residential rekeys, and a gate lock that shares keys with the house is often worth rekeying or replacing at the same visit. If you want the gate and the doors on one key plan, our lock rekey service covers the door side.
Garden apartments, condo complexes and small multi-unit rentals bring a different problem: shared pedestrian gates where many people have access and turnover is steady. Along Western Avenue, apartment complexes are a regular source of lockouts and mailbox lock changes. If a property there has a pedestrian gate, the same visit can cover the gate latch or code, and the mailbox lock replacement service can handle the mailboxes. Landlords and property managers can read more on our locksmith for landlords page.
The Rosecrans and Artesia corridors mix light-industrial buildings with homes. There, the gate is more likely to be a yard or vehicle gate with a chain, a hasp or a heavy-duty lock rather than a decorative latch. We already work on warehouse and roll-up door locks in those corridors, and commercial properties with gated yards can look at our commercial locksmith page.
Because Gardena has security doors and window bars on much of its older housing, many owners already think about security in layers. A gate that actually latches is the first layer, and it is often the one that gets neglected.
We are about 17 miles from our Westwood storefront, and our mobile vans serve Gardena directly.

Call (213) 577-1366What should I do before I call about a gate that won't lock?
A few quick checks can save time, and a few things are best left alone.
- Take a photo of the lock, the latch and the strike plate, and one of the whole gate. It helps us bring the right parts.
- Note what the gate is made of and whether it is a side, pedestrian or driveway gate.
- If it is a keypad or electronic lock, replace the batteries first. Dead batteries cause a surprising number of calls.
- Check whether the gate has dropped. Look at the gap at the latch side compared with the hinge side.
- Do not force the key or hammer the latch. A key that breaks in the lock turns a small repair into a larger one.
- Avoid heavy oil sprays on the lock cylinder. They attract dust and grit and often make things worse within weeks.
- If the gate will not latch at all, secure it temporarily so it does not swing open while you wait, but do not drill into the frame yourself.
Frequently asked questions
Can you repair a gate lock the same day I call in Gardena?
We answer the phone 24 hours a day, 7 days a week at (213) 577-1366, and our mobile vans work on site. Call, describe the gate, and we will tell you when a van can reach you and what the visit is likely to involve.
Is it better to repair or replace a gate lock?
If the lock body is sound and the problem is alignment, a worn part or a seized cylinder, repair is usually the more economical route. Replacement makes sense when the lock is corroded, was never rated for outdoor use, is a model with no parts, or when you want to switch to a keypad or electronic lock. We will tell you which applies after inspecting the gate.
My key turns but the gate won't stay latched. Why?
Most often the gate has dropped slightly, so the bolt no longer meets the strike plate properly. It can also be a broken internal part in the lock, or a bent latch. We check alignment first, because replacing the lock without fixing the alignment usually brings the same problem back.
Can you install a keypad lock on my existing side gate?
Usually yes, but it depends on the gate. We look at the material, the thickness of the frame, and whether the gate closes fully on its own. A keypad lock on a gate that doesn't latch by itself will not protect anything, so we may adjust hinges or the closing action first.
Are electronic and smart gate locks reliable outdoors in Gardena?
A properly rated weather-resistant gate lock handles Gardena's climate well. The area has marine layer and damp mornings but very little direct salt exposure, so heavy corrosion is less of a concern than ordinary wear. The thing to watch with electronic and smart gate locks is power, so batteries or wiring need to be dependable.
Do you repair driveway gate motors and openers?
Our work is the gate lock and latch hardware. If your driveway gate won't lock because of a motor, opener or control board fault, we will say so honestly after looking at it rather than replacing a lock that isn't the problem.
Can you rekey or change the code on a gate lock when a tenant moves out?
Yes. Keyed gate locks can often be rekeyed so old keys stop working, and keypad locks can have their codes reset. If the lock is badly worn, replacing it may make more sense than rekeying. Our lock rekey service handles the door side of the same turnover at lock rekey.
How much does gate lock repair cost?
It depends on the gate material, the type of lock, whether alignment or hinge work is needed, the hardware grade, any electrical component, and the time of the visit. We don't post numbers because every gate is different, but you will hear what applies to your situation before work begins.
