Why won't my ignition key turn?
A key that won't turn is rarely random. Something specific is holding the cylinder, and it usually comes down to one of four causes.
Each one feels a little different in your hand. A bound steering lock gives slightly and then stops dead. A worn key works some days and not others. A failing cylinder often feels rough or loose, or the key turns freely and nothing happens in the car. When you call, describe what you feel. It helps us decide what to bring up the 60 before we ever leave the van.
- The steering wheel lock is engaged. If the wheel got bumped after the engine was shut off, the lock bolt can bind against the steering column and hold the cylinder still.
- The key is worn. Years of use round off the cuts, and the wafers inside the cylinder stop lining up the way they were built to.
- The cylinder is worn or damaged. Wafers and springs wear, bend, or break, and the cylinder starts to feel gritty, sticky, or loose.
- Something behind the cylinder has failed, such as the ignition switch or part of the shifter interlock, so the cylinder looks like the culprit when it isn't.
What should I do if my key is stuck in the ignition?
Stay calm and don't force it. Pliers, hammers, and heavy leverage are how a stuck key becomes a snapped key, and a snapped key is a bigger repair than the one you started with. Here is what is worth trying before you call.
If the key has already broken off inside the cylinder, that is a different job, and our broken key extraction page explains how we handle it. And if the key is stuck and you are also locked out of the car, tell us when you call so we plan for both problems at once.
- Make sure an automatic is fully in Park. Many cars will not release the key from any other position.
- Turn the steering wheel gently left and right while putting light turning pressure on the key. This frees a bound steering lock more often than anything else.
- Look at the key. If it is bent, cracked, or carrying a heavy ring of other keys, take the weight off the cylinder and try again with a light touch.
- If it still won't move, stop. Skip heavy oils and household sprays, which can gum up the wafers and make the repair harder, and call us.

Call (213) 577-1366How do we repair an ignition cylinder?
Ignition work is not guesswork, and it should not be a lottery of swapping parts until something works. This is how a typical call goes with us. The details change by vehicle, and we confirm what your car needs by VIN or in person rather than assuming from the make alone. Our broader automotive locksmith work follows the same approach.
- You call (213) 577-1366, and a real person answers around the clock. We ask the year, make, and model, what the key does or doesn't do, and where the car is parked.
- A technician from our own company drives out in a mobile van. There is no handoff to a dispatch middleman.
- Before working on the ignition we ask for ID and proof the vehicle is yours, such as registration. That protects you as much as it protects us.
- We diagnose first: test the key, check the steering lock, inspect how the cylinder moves, and check whether the problem sits behind the cylinder instead.
- We explain what we found and what the repair involves, including what affects cost, before any work begins.
- We repair, rekey, or replace the cylinder as needed, and cut or program keys to match when the job requires it.
- We test it properly: start the car more than once, try every key you hand us, and make sure the key releases cleanly when you shut off.
Repair, rekey, or replace: how do we decide?
The usually more economical route is the one that fixes the actual fault and nothing more. If the cylinder is mechanically sound and only the key is worn, a freshly cut key can solve the problem without opening the steering column at all. If the cylinder itself is worn, we can often service or rebuild it. If it is damaged past that point, replacing the cylinder and making keys that match is the sensible fix.
Newer vehicles add a wrinkle. Many have an anti-theft system that expects the key's chip to be recognized, so a new cylinder or key may also need transponder key programming before the car will start. Whether yours does depends on the vehicle, which is why we confirm by VIN rather than quote from memory.
We will also tell you plainly when a job is dealer territory. Some vehicles tie the ignition to the body computer or immobilizer in ways that need dealer-level software or parts. If your car is one of those, we say so up front instead of starting something we can't finish, and we'll point you in the right direction.

Call (213) 577-1366What affects the cost of ignition repair?
We do not publish numbers on a web page because ignition work varies too much for a number to be honest. What we can do is tell you exactly what moves the cost up or down, and give you a firm quote once we have seen the car.
Ask any locksmith for the same breakdown. If a company quotes a flat figure over the phone without knowing your vehicle, be cautious.
- Year, make, and model. Some ignition assemblies are simple and common; others are specialized and harder to source.
- Repair versus replacement. Servicing a worn cylinder generally involves less in parts than replacing the whole assembly.
- Keys. Whether we need to cut a new key, match an existing one, or program a chip.
- What sits behind the cylinder. If the ignition switch or another component has failed, that is additional work.
- Column access. How much trim has to come off to reach the cylinder differs by vehicle.
- Parts availability. Common parts may be on the van; unusual ones may need to be sourced.
- Time and place. Night and weekend calls and distance to the vehicle are factored in, and we explain them up front.
What does ignition trouble look like in Walnut?
Walnut is a city of tract homes, hillside lots, and driveways, in ZIP code 91789, and the cars that live there tend to be parked in the same few places every day. That shapes the calls we get.
Around the Mt. SAC campus area, one familiar scenario is student vehicle trouble and key replacement. A key that has been used daily for years eventually stops turning smoothly, sometimes in a parking lot between classes. When the key is the worn part, the fix is often a properly cut replacement rather than a new ignition, and we check that before recommending anything bigger. On the Amar Road corridor and the Grand Avenue corridor, a car that won't start affects a working day, so tell us when you call if you are on a tight schedule. Up in Walnut Hills and other hillside streets, parking with the wheels turned against a slope puts load on the steering lock, which is a classic reason a key refuses to turn. Gently wiggling the wheel as described above often frees it.
Heat is part of living here. Hot inland-valley summers do not typically damage an ignition cylinder, but a baked cabin and a frustrated afternoon make people force keys that shouldn't be forced. Santa Ana dust is mostly an exterior-hardware issue, so we don't blame it for ignition problems unless we find it.
Our storefront is at 10740 Wilshire Blvd in Westwood, about 39 miles from Walnut, so Walnut calls are handled by a mobile locksmith van. Ask for an arrival estimate when you call, and we will give you an honest one for where you are.

Call (213) 577-1366When the key is the real problem
Not every ignition complaint is an ignition problem. A worn, bent, or poorly cut copy can mimic a bad cylinder, and the reverse is also true: a fresh key that still won't turn tells us the cylinder is the culprit. That is why we test with your key and, if you have one, a spare before replacing anything.
If testing shows the key is worn out, we can talk through car key replacement options for your vehicle. If you have no working key at all, say so on the phone so we can plan accordingly. We keep this page about the ignition itself, but we will not send you away with a repaired cylinder and a key that is about to fail.
Why call Wilshire Lock & Key?
We have been in business since 1987, and ignition problems were part of the trade long before most keys had chips. We serve 140 cities across Los Angeles and Ventura counties, Walnut among them.
A few things we can say honestly about how we work:
- One company, start to finish. The person who answers the phone works for us, and so does the technician who shows up. No dispatch middlemen reselling your call.
- A real storefront and mobile vans. We have a physical shop in Westwood and bring the work to you.
- David's oversight. David is the owner and lead technician, and he stands behind how our work is done.
- We answer 24 hours a day, seven days a week, year-round at (213) 577-1366.
- We tell you what we find. If it is the key, we say so. If it is dealer-only, we say so.
What should you ask any locksmith before they touch your ignition?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are considering for that license number, and check it yourself. It is a fair question and a good company will answer it without hesitation.
Also ask whether they will ask for proof of ownership, whether the quote covers parts and keys or only labor, and who will actually come to your car. If you would rather talk it through first, reach us through our contact page or call (213) 577-1366.
Frequently asked questions
Can you fix my ignition without replacing it?
Often, yes. If the cylinder is worn but still sound, we can service or rebuild it. If the real problem is a worn key, a new cut may be all you need. We diagnose first and tell you which applies before doing anything bigger.
Why does my key turn only some of the time?
That pattern usually points to a worn key, worn wafers inside the cylinder, or a steering lock that binds in certain wheel positions. It tends to get worse, so it is worth having it looked at before the key stops turning completely.
Can a dead battery make my key stick in the ignition?
On some vehicles, yes, because the key release or shifter interlock depends on electrical power. It varies by car, which is why we check by VIN or in person. If your battery is weak, mention that on the phone.
Will I need a new key after the ignition is repaired?
Sometimes. If we rekey or replace the cylinder, the keys have to match it. If your vehicle uses a chip key, programming may also be part of the job. We will explain what your vehicle needs before we start.
Do I need to prove the car is mine?
Yes. Before we work on an ignition we ask for ID and proof of ownership, such as registration. It is a standard step that protects you from anyone trying to take a vehicle that isn't theirs.
Can you come to me in Walnut, or do I have to tow the car?
In most cases we come to you. Our mobile vans do the work where the car is parked, whether that is a driveway, a lot near Mt. SAC, or a business parking space. If a repair truly needs a shop or a dealer, we say so.
Do you work on ignitions at night and on weekends?
Yes. Our phone is answered 24 hours a day, seven days a week, year-round at (213) 577-1366. After-hours calls can affect cost, and we explain that before the work starts.
Is a locksmith able to do this instead of the dealer?
For many vehicles, yes, and it is often more convenient because we come to you. Some vehicles do require dealer-level software or parts, and we tell you honestly when yours is one of them.
How long does an ignition repair take?
It depends on the vehicle, what failed, and whether keys must be cut or programmed. Rather than promise a time, we give you an honest estimate once the technician has seen the car.
