Ignition repair in Pomona, CA: keys that won't turn and worn cylinders

What is actually wrong when your ignition key won't turn?

An ignition key that won't turn is one of the more stressful car problems because it tends to happen at the worst moment. You are in the driver's seat, the car is parked somewhere you didn't plan to stay, and the key goes in but nothing else happens. Sometimes the key won't seat all the way. Sometimes it turns a hair and then stops. Sometimes it turns but the car does nothing, or the key refuses to come back out. Each of those points to a slightly different cause, and describing exactly what happens when you call helps us work out what we are dealing with before a van is on the road.

Mechanically, the ignition is two things working together. The lock cylinder reads the cuts on your key, much like a door lock does. Behind it sits the switch that sends power to the starter and the rest of the car. Add the steering column lock, a small pin that locks the wheel when the key is out, and you have three places where something can bind. Trouble inside the cylinder is locksmith work. A failed electrical switch behind the cylinder is sometimes a job for an auto electrical shop, and we will tell you plainly which one you have rather than sell you a repair you don't need.

Why does a key get stuck or refuse to turn in the ignition?

Most ignition problems build slowly and then show up all at once. The key that worked fine yesterday can feel gritty for a few weeks first, and people usually ignore that until the day it stops. These are the causes we see most often when someone describes a car key stuck in the ignition or an ignition that won't turn:

• The steering lock is binding. If the wheel was turned against a curb or bumped after you shut the car off, the lock pin presses hard against the column and the key can't rotate. This is the easiest cause to fix and often needs no repair at all.
• The key itself is worn. Years of use round off the cuts, and a key copied from a copy carries small errors with it. A worn key can pick the wrong positions inside the cylinder and jam.
• The cylinder is worn. Inside are small wafers or tumblers and springs. After enough years they wear, weaken or stick, and the cylinder stops responding to even a good key.
• Debris and residue. Lint, dust, sticky drink residue and the breakdown of old lubricant can gum up the inside of the cylinder.
• A bent or damaged key. A heavy keychain hanging from the ignition bends keys and wears the cylinder face over time.
• A shifter or interlock condition. On some cars the key will not turn or release unless the shifter is fully in Park and other conditions are met.
• A broken key piece inside the cylinder. That is a separate problem with its own tools, and we cover it under broken key extraction.
• A key that turns but the car won't start. That points away from the cylinder and toward the battery, the starter, or the vehicle's anti-theft system reading the key chip.

What can you safely try before calling a locksmith?

A few careful checks cost nothing and sometimes solve the problem on the spot. They also give us better information if you do end up calling. The one rule that matters most: stop forcing it. Force is how a repair becomes a replacement.

1. Check the shifter. Make sure the car is fully in Park, or in the position your owner's manual requires, and press the brake if your car asks for it.
2. Work the steering wheel. Turn the wheel gently left and right while applying light turning pressure on the key. If the steering lock was binding, the key will often release as the wheel moves.
3. Try your spare key. If the spare turns smoothly, the original is probably worn, which is useful to know. If neither key works, the cylinder is the more likely culprit.
4. Look at the key. A bent, cracked or worn-smooth key should be retired. Stop using it so it does not do more damage inside the cylinder.
5. Do not hammer, pry, or use pliers. A snapped key or a damaged cylinder face turns a straightforward repair into a larger one.
6. Skip household oil sprays. They can seem to help for a day, but over time they attract grime into the cylinder.
7. Call (213) 577-1366 and tell us what the key does: won't go in, won't turn, turns but nothing happens, or won't come out.

How do we repair an ignition cylinder step by step?

Every ignition job is a little different, but the process follows the same honest order. We diagnose before we repair, and we repair before we replace.

1. You call and describe the symptoms, along with the make, model and year of the car. We ask whether you have a spare key and whether anything unusual happened just before the problem started. Over the phone we can tell you what is likely, but we do not pretend to know for certain until we have the car in front of us.
2. A mobile van comes to where the car is parked, whether that is a driveway, an apartment lot or the side of the street. If a job turns out to need bench work, we will say so and explain the options, which can include our storefront at 10740 Wilshire Blvd in Westwood.
3. We confirm the car is yours. That means asking for ID and registration or similar proof. It is standard practice for anyone in this trade, and it protects you.
4. We diagnose. We test the key, inspect it for wear, check the steering lock, and see how the cylinder responds. This is where we separate a cylinder problem from a steering lock, a shifter interlock or an electrical fault.
5. If a key is stuck, we free it carefully, without forcing the cylinder.
6. We choose the repair path: clean and service a cylinder that is still sound, rebuild it with new internal parts, or replace it and cut a key to match.
7. We test the result. The key should enter smoothly, turn through every position, return without sticking and come out freely. Where the car's anti-theft system is involved, we confirm the car recognizes the key before we call the job done.
8. We explain what failed and which old keys should be retired, so you know what to do differently.

Repair, rebuild or replace: what are the real options?

A worn ignition cylinder does not always need replacing. If the wear is moderate, servicing or rebuilding the cylinder can bring it back, and that is usually the more economical route. If the internals are badly worn, the cylinder face is damaged or a key has snapped inside it, replacement is the sensible choice, and we cut a new key to match.

Newer vehicles add a layer that older ones did not have. Many cars use a key with a chip in it, and the car checks that chip before it will start. Whether a replacement ignition cylinder needs its key programmed, and how that is done, depends entirely on the vehicle. We do not guess at that. We confirm by VIN and in person before we promise a repair path, and if your vehicle is one where certain parts or programming can only be done through the dealer, we will tell you that honestly rather than start work we can't finish. Where chip programming is part of the job, our page on transponder key programming explains how that side works.

If the real issue is that you have lost your only key, or the key is too worn to trust, a different service fits better. See car key replacement for worn or damaged keys and lost car key replacement for when no working key exists. Those jobs often overlap with ignition work, and we will sort out which applies when we see the car.

What affects the cost of ignition repair in Pomona?

We do not quote numbers on a web page because ignition jobs vary too much for a number to mean anything. What we can do is tell you exactly what moves the cost, so you know what you are being quoted for. Ask for the full quote before work begins from any locksmith you call.

These are the main factors:

• The vehicle. Make, model and year determine how the ignition is built, what parts exist and whether anti-theft programming is involved.
• Repair or replacement. Servicing a cylinder that is still sound generally costs less than replacing it and cutting new keys.
• Parts. Availability matters, and so does whether the part comes from the aftermarket or from the manufacturer. On some vehicles the part is dealer-only.
• Key and chip work. If the new cylinder or a replacement key must be programmed to the car, that adds labor and equipment.
• The condition of the key. A key broken inside the cylinder adds a removal step before any repair can start.
• Where and when. A service call to a location in Pomona, which is roughly 43 miles from our Westwood base, and the time of day you need us, can both affect the total.
• A different underlying fault. If the diagnosis shows the problem is elsewhere, such as the steering lock or the electrical switch, the work and cost change accordingly.

Why call Wilshire Lock & Key for ignition problems?

We have been in business since 1987, and that is a long time to have looked inside a lot of worn ignition cylinders. We operate from a real storefront at 10740 Wilshire Blvd in Westwood and run mobile service vans, so the work happens either at your car or, when it truly needs it, at our shop. When you call (213) 577-1366, you are reaching our own company. We are not a dispatch middleman who takes your call and hands it to whoever is available, so the person who answers is connected to the people doing the work. The owner and lead technician, David, oversees the work.

One honest note on credentials: California requires locksmith companies to hold a license with the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are considering for that license number before they touch your car. It is a fair question, and you should get a straight answer.

Our phone is answered 24 hours a day, 7 days a week, year-round, because a car that won't start doesn't wait for business hours. If you want to understand the wider range of vehicle work we do, our automotive locksmith page covers it, and the mobile locksmith page explains how van service works. For after-hours situations, see our 24-hour locksmith page.

Where ignition trouble shows up around Pomona

Pomona covers ZIP codes 91766, 91767 and 91768, and ignition problems don't stay in one part of town. A car with a sticking key can be parked in the driveway of a postwar tract house, in the lot of an apartment building along the Garey Avenue corridor, or on a street in Ganesha Hills, and our vans are built to work where the car already is. If you are in Phillips Ranch, the planned community in the southwestern hills, or in Spadra near Cal Poly Pomona, you do not need to get the car anywhere. Tell us the cross streets or lot and we will plan from there.

Fairplex brings its own situation. On event days, vehicles crowd the lots, and keys get lost, locked in, jammed or abused in the rush to leave. If the problem is a locked door rather than a stuck key, that is a car lockout. If the key is in the ignition and won't turn or come out, that is the work on this page. A big crowd and a car that won't move is a bad combination, so it helps to tell us up front which one you have.

Pomona's inland valley location also means hot, dry summers. Heat is hard on anything already worn, including old plastic key heads and cylinders that were marginal in spring. A key that felt a little rough in cooler months is the sort of thing that can turn into a stuck key during a long summer stretch. If your key has been feeling gritty, getting it looked at early is easier and usually less costly than waiting until you are stranded.

Because Pomona is about 43 miles from our storefront, we ask you to call as early as you can so we can plan the trip. We will not promise an arrival window until we know where our vans are, but we will tell you honestly what to expect once we do.

How can you keep an ignition from failing?

Most ignition failures are slow, and a few habits make a real difference. None of these require tools:

• Lighten the keychain. A heavy bundle hanging from the key bends the key and wears the cylinder over time.
• Retire worn keys. If a key sticks, is visibly rounded or has been copied from a copy, replace it before it damages the cylinder.
• Do not use the key as a tool. Prying, scraping or opening boxes with it bends the blade.
• Keep a good spare, and test it. A spare you have never tried is not a spare.
• Pay attention to early warning signs: a gritty feel, needing to jiggle the key, or a key that sticks only sometimes.
• Never force a key that will not turn. Stop, check the steering wheel and shifter, and call if it does not give.
• If your key fob is also failing, see our key fob replacement page, since fob trouble and ignition trouble are sometimes confused.
