Why won't my ignition key turn?
An ignition key that won't turn is one of the more frustrating car problems, because the car is usually fine. The battery is good, the fuel is there, and the engine would start if the key would only rotate. The trouble sits in a small brass-and-steel assembly behind the key slot, and it tends to fail in a handful of predictable ways.
The most common cause is wear. Every time you start the car, the key slides past a set of tiny spring-loaded wafers or pins inside the ignition cylinder. Over years and thousands of starts, those parts wear down, and so does the key. A worn key paired with a worn cylinder stops lifting every wafer to the exact height it needs, and the cylinder refuses to rotate. Often you can feel it getting worse for weeks first: you wiggle the key, jiggle the wheel, and it eventually works. Then one day it doesn't.
Other causes are less about age. The steering column lock can bind against the wheel if the front tires were turned against a curb when you parked, which makes the key feel jammed. Debris and lint from a crowded key ring can foul the cylinder. A bent or cracked key will not align the wafers. And a heavy ring of keys and charms hanging from the ignition adds constant side load that accelerates wear on the cylinder over time.
The keywords people type into a phone at the worst moment are usually some version of this: ignition won't turn, key stuck in ignition, car key stuck in ignition. They are all describing the same family of faults, and a trained ignition repair locksmith can sort out which one you have by looking and feeling, usually without disassembling anything at first.
What should I do if my key is stuck in the ignition?
Before you call, a few gentle checks can save you a service visit, and they can also keep a small problem from becoming a bigger one. The rule that matters most is simple: do not force it. A key snapped off inside the cylinder turns a repair job into a broken key extraction job first, and that adds work for everyone.
- Make sure the shifter is fully in Park (or Neutral for a manual). Many cars will not release the key or turn it unless the transmission position is registered correctly.
- Turn the steering wheel gently left and right while applying light turning pressure to the key. If the steering lock is binding, the wheel will give a little and the key will free up.
- Check that the key is fully seated. A key that is not pushed all the way in will not turn, and a bent key often sits slightly proud of the slot.
- Remove the extra weight. Take the rest of your key ring off the ignition key if you can reach it without pulling on the key itself.
- Try your spare key. If the spare turns smoothly and your main key does not, the main key is probably worn. If neither turns, the cylinder is the likelier culprit.
- Stop if you feel grinding, metal-on-metal resistance, or the key starting to bend. That is the point where more force makes things worse.

Call (213) 577-1366How we handle ignition repair, step by step
Every ignition job starts with a conversation and a look, not a part swap. Ignition cylinders and the electronics around them differ a lot between makes and years, so we work through the same sequence each time and adjust to what we find. Because our mobile locksmith vans carry the tools to do this at your car, you generally do not need to tow it anywhere for the diagnosis.
- You call (213) 577-1366 and tell us the year, make, and model, what the key is doing, and where the car is. We ask whether the key is stuck, turns partway, or will not go in, because each points in a different direction.
- We arrive at the car and confirm ownership. We ask for ID and some proof the vehicle is yours, because we will not work on a car for someone who cannot show a connection to it.
- We inspect the key and the cylinder. A worn or bent key gets compared against the cylinder behavior, and we check the steering column lock, shifter position, and any debris in the keyway.
- We tell you what we found and which option makes sense: cleaning and freeing the cylinder, repairing it, rekeying it, or replacing it. You hear the options and the reasons before any work begins.
- We carry out the repair. Where the vehicle has a transponder or immobilizer system, we check whether the key and the car still recognize each other afterward, and we confirm by VIN or in person whether programming is needed for your specific vehicle.
- We test it properly. We start the car, cycle the key through its positions, and check that the steering lock releases. Then we hand you a working key and explain what to watch for.
Repair, rekey, or replace the ignition cylinder?
These are three different jobs, and the right one depends on what is actually wrong. We would rather explain the difference than push you toward the most involved option.
Repair means working with the existing cylinder: cleaning it, freeing a sticky wafer, or replacing a worn internal part. It is often the more economical route when the cylinder is basically sound and the problem is minor or caused by a bad key. Sometimes a freshly cut key from the vehicle's key code solves the whole thing, because the old key was the weak link.
Rekeying changes the cylinder so it works with a new key. This makes sense when keys have been lost or stolen and you want old ones to stop working, or when the cylinder is intact but you want everything matched to one key again. On some vehicles the ignition and the door locks use the same key pattern, and we will tell you whether that applies to yours.
Replacement means installing a new or remanufactured cylinder. It becomes the sensible path when the internal wear is bad enough that a repair would not last, when the cylinder has been damaged by an attempted theft, or when the cylinder housing is cracked. Newer cars add another layer: the key often carries a transponder chip, and the car's computer may need to be taught to accept it. See our page on transponder key programming for how that part works.
One honest caveat: some makes and models limit certain parts or procedures to the dealer, whether that is a specific cylinder assembly or a security-related reset. We do not guess. If your vehicle falls in that category we will say so plainly, tell you what we can and cannot do, and not leave you paying for a visit that could not solve the problem.

Call (213) 577-1366What affects the cost of ignition cylinder repair?
We do not quote prices on a web page, because an honest number depends on facts we do not have until we know your car. Here is what actually moves the cost of ignition work up or down, so you know what you are being asked to pay for.
- The vehicle itself. Year, make, and model decide how the ignition is built, how hard it is to reach, and which parts exist.
- The diagnosis. A key that is simply worn out is a much smaller job than a cylinder that has seized or been damaged.
- Repair versus replacement. Freeing or repairing a cylinder generally involves less than installing a new one, and new cylinders vary in cost by vehicle.
- Transponder and immobilizer systems. If the car needs a key or cylinder programmed to its computer, there is added work and sometimes additional equipment involved.
- Key cutting. A new key that must be cut and possibly programmed is a different line item than one that works fine after repair.
- Time of day and location. Late-night and weekend calls, and how far we travel, can factor into the final figure.
- What else is wrong. Sometimes the ignition problem is really a steering lock or electrical issue, which changes the scope.
Why call Wilshire Lock & Key for ignition work?
We have been in business since 1987, and in that time ignition problems have been a steady part of what people call us about. We would rather tell you what sets us apart in plain terms than make big claims.
We are one company. When you call (213) 577-1366, you reach us, not a national call center that sells your job to whoever picks it up. There is no dispatch middleman between you and the technician who shows up. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so there is a real place behind the phone number, and our automotive locksmith work is handled by our own people.
David, the owner and lead technician, oversees our work. For ignition repair, that matters, because the decision between repairing and replacing a cylinder is a judgment call, and we want that call made by someone with decades of context rather than by a script.
The phone is answered 24 hours a day, 7 days a week, year-round. A stuck key does not wait for business hours, and neither do we.
One more point worth knowing as a customer: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they work on your car. It is a fair question and a good habit, whoever you call.

Call (213) 577-1366Ignition repair around Monterey Park
Monterey Park sits on the western edge of the San Gabriel Valley, and the city covers ZIP codes 91754 and 91755. We are based on Wilshire Boulevard in Westwood, so Monterey Park is roughly 19 miles from our storefront, and our mobile vans cover the city and surrounding areas across Los Angeles and Ventura counties.
Most ignition calls we would expect here come from the places people actually park and drive. Along the Garvey Avenue corridor and in the Atlantic Boulevard business district, cars sit in shopping and restaurant parking lots, and a key that will not turn at the end of a long shift is a real problem. Delivery and work vehicles that rack up daily starts wear ignition cylinders faster than a weekend car does, and those starts add up quickly.
Up in the Monterey Highlands in the northeast hills and on the northern hillsides near Alhambra, homes often have long driveways and detached garages. A car with a stuck key tends to be sitting where it is hard to push out of the way, which is one reason a mobile visit that comes to the driveway is more practical than arranging a tow for what may be a small repair. Hillside streets also mean cars are often parked with the wheels turned toward the curb, and that can leave the steering lock tight against the column and make a perfectly good key feel stuck. Try the wheel-and-key technique first, as noted above.
Near East Los Angeles College in southwest Monterey Park, student and commuter cars with older keys and heavy key rings are common, and that kind of wear matches what we see in ignition cylinders. The same area also comes up for car key replacement, and when you have only one key that is already worn, it is worth getting a fresh key made before the cylinder or the key finally gives out. See our car key replacement page if that sounds like you.
As for weather, Monterey Park has warmer summers than the coast, with marine-layer mornings common in May and June, and sun-exposed hillside surfaces weather faster than those in the flats. The effect on locks is modest, so we do not blame the climate for most ignition failures. Wear, worn keys, and heavy key rings are the usual causes, whichever side of town you live on.
When it is not really the ignition
Sometimes what looks like an ignition failure is something nearby, and it is worth knowing before you spend money. A car that clicks but will not crank is usually a battery or starter issue, not a cylinder problem. A key that turns freely but the engine does not start can point to a transponder or immobilizer fault, where the car does not recognize the key. A dead or damaged remote is a different matter from the key blade, and our key fob replacement service handles that side.
If you are locked out with the key inside the car rather than stuck in the ignition, that is a separate situation, covered under car lockout. And if the key is lost entirely, you are looking at lost car key replacement, where the ignition may be perfectly healthy.
When you call, describe exactly what the key and car do. We will tell you honestly if what you describe sounds like something another trade should handle, and we will not turn up with a cylinder you do not need.

Call (213) 577-1366How to keep an ignition cylinder from wearing out
A little care extends the life of an ignition considerably, and none of it costs much.
- Take the weight off the key. Use a light ring with only the ignition key and perhaps the fob, and keep the rest of your keys separate.
- Replace worn keys early. A key with rounded edges or a visible bend is wearing the cylinder every time it goes in.
- Do not force a sticking key. If it feels tight, stop and look for the cause, since forcing it often turns an easy fix into a repair.
- Keep a good spare. Have a spare cut from a good original, not copied from a worn copy, because errors compound with each generation.
- Keep the keyway clean. Avoid spraying heavy oils into the ignition, and ask us before putting anything in there.
- Act on early warnings. A key that works only after jiggling is telling you the cylinder is on its way out, and it is cheaper and easier to deal with it on your schedule than on a roadside at night.
Frequently asked questions
Why does my car key go in the ignition but not turn?
The usual causes are a worn key, a worn ignition cylinder, a steering column lock binding against the wheel, or debris in the keyway. Check that the shifter is fully in Park and gently rock the steering wheel while turning the key. If that does not free it, stop forcing it and call us at (213) 577-1366.
What do I do if my key is stuck in the ignition?
Confirm the car is fully in Park, gently move the steering wheel side to side while applying light pressure on the key, and remove extra weight from the key ring. Do not pull hard or use pliers, since that can break the key. If it still will not move, call us and we will come to the car.
Can you repair an ignition at my home or do I need to tow the car?
In most cases we can diagnose and repair the ignition where the car is parked, whether that is a driveway, a parking lot, or the street, because our mobile vans carry the tools. Occasionally a vehicle needs work that has to be done at a dealer, and if so we will tell you honestly after we look at it.
Will I need a new key if the ignition cylinder is replaced?
Sometimes, yes. A new cylinder comes with its own key pattern, or it can be matched to your existing key depending on the vehicle. If your car has a transponder chip, the key and the car may also need to be programmed to work together. We confirm what your car needs by VIN or in person rather than guessing.
Is a worn key or a worn ignition the problem?
We can usually tell quickly. If a spare key works smoothly where your main key struggles, the main key is probably the weak part, and a fresh key may be the lighter-cost fix. If both keys struggle, the cylinder is more likely to be worn.
How much does ignition repair cost?
It depends on your vehicle, whether the cylinder can be repaired or has to be replaced, whether the key is transponder-equipped, and when and where you need service. We do not give blanket prices over the web, but we explain the options and what drives the cost when you call (213) 577-1366, before any work begins.
Do you handle ignition problems at night and on weekends in Monterey Park?
Yes. Our line is answered 24 hours a day, 7 days a week, year-round, and our mobile vans serve Monterey Park including both the 91754 and 91755 ZIP codes. Late-night and weekend calls can affect the cost, and we will explain that on the phone.
How do I know a locksmith is legitimate before they work on my car?
Ask for their California BSIS LCO locksmith company license, and expect to be asked for ID and proof of ownership for your vehicle. A legitimate locksmith will not be bothered by either question, and neither will we.
