Your key goes in but will not turn

The key seats all the way and then stops dead. Two of the four common causes are free and take under a minute: a steering column lock loaded under wheel tension, and a shifter that is not fully seated in Park. Work through those before you pay anybody, including us. If the key still will not rotate, the fault is in the key bitting or in the ignition lock cylinder, and both are fixed where the car is parked.

25 technicians on rotation

First: is your key blocked or spinning?

A key that will not rotate and a key that spins freely feel similar in your hand and are opposite failures. If the key is locked solid and the plug will not move, you are on the right page: that is a mechanical block, and the four causes below cover almost all of it. If the key rotates normally but nothing happens, the lock cylinder is doing its job and the fault sits behind it, in the ignition switch, the immobilizer or the starting circuit. Read the right one, because the repairs share no parts.

Try This Before You Call Anyone

Four checks, and two of them are free

Work these in order. Two of the four common causes cost nothing and take under a minute, and we would rather you fix it yourself than pay us for a drive-out.

  1. 1

    Stop pulling on the key

    Force is what turns a twenty-second fix into a broken-key extraction. A key blade snaps at the shoulder under far less torque than people expect, and a snapped blade inside the plug is a separate job. Take the load off the key before you do anything else.

  2. 2

    Unload the steering column lock

    When you pull the key, a spring-loaded lock pin drops into a slot in the steering shaft. If you parked with the wheel turned, or the front tires are pressed against a curb, the weight of the car holds that pin hard against the slot and the plug physically cannot rotate. Put light, steady turning pressure on the key, about what you would use on a house key, and rock the wheel gently left and right with your other hand. The key turns by itself the instant the pin is free.

  3. 3

    Seat the shifter fully in Park

    On an automatic, the shift interlock (BTSI, Brake Transmission Shift Interlock) ties the ignition to the shifter position. A shifter that looks like it is in Park but is one notch short, or a worn park position switch, will hold the key. Push the lever firmly into Park. If that changes nothing, hold the brake, move it to Neutral, and try the key there.

  4. 4

    Try the spare key

    This is the test that decides the whole diagnosis, and it costs nothing. If the spare turns and your everyday key does not, the everyday key is worn: the cuts have lost depth and no longer lift the wafers to the shear line. If both keys fail the same way, the key is not the problem and the fault is in the cylinder or the column.

Lock Cylinder vs Ignition Switch

Two different parts, and almost nobody separates them

The ignition lock cylinder and the ignition switch are two different parts, and almost every page written about this symptom treats them as one. The lock cylinder is the mechanical assembly your key enters. The ignition switch is the electrical unit mounted behind or below it, usually driven by a rod or a cam gear, and it carries the ACC, ON and START circuits. A key that will not rotate is a lock cylinder or steering column problem. A key that rotates freely and produces nothing is an ignition switch or immobilizer problem. Same hole, different parts, different repair.

Automotive ignitions are wafer locks, not pin-tumbler locks. Inside the plug are flat, spring-loaded wafers that must be lifted to exactly the shear line by the cuts on your key before the plug can turn. That matters because it explains the two ways this fails mechanically: the wafers wear and stop seating cleanly, or the key wears and stops lifting them far enough. A page that talks about pins in a car ignition was not written by anyone who has had a steering column apart.

A worn key is the cause people most often get wrong, because the key looks fine. Bitting wears a few thousandths at a time over years in a pocket, and the failure is gradual until the day it is total. The correct fix is a key cut to code from the VIN, or cut from depths decoded directly off the lock. The wrong fix, and the one a kiosk will happily sell you, is a copy of the worn key: a copy reproduces the worn cuts and fails exactly the same way, usually within weeks. Read how cutting to code differs from duplicating a key.

There is no trouble code for a key that will not turn

A key that will not rotate is a mechanical failure, and it sets no diagnostic trouble code. The engine control module was never asked to do anything, because the ignition never reached START. No scan tool will read a code for this, because there is no code to read. If a shop quotes you a diagnostic code for a key that will not turn, they are either describing a different symptom or selling you one.

How to verify a locksmith before you let them workWhat NASTF VSP actually authorizes
Ignition Lock Cylinder Symptoms

What a failing cylinder feels like

If you recognise more than one of these, the cylinder has been telling you for a while. They do not reverse on their own.

Key stops dead at zero degrees

No movement at all in either direction. Usually the steering column lock under load, or a wafer stack that is no longer aligning. Check the wheel first, always.

Key sticks part way around

It reaches ACC or ON and jams before START. Classic worn-wafer behaviour: enough alignment to start the rotation, not enough to finish it.

You have to jiggle it every time

A cylinder that only works at a particular angle, or with the key pulled back a hair, is already failing. The day it stops responding to the trick is the day you call somebody.

The key falls out while the engine runs

Tumbler wear letting the plug release at ON. The car drives, so it gets ignored, and then one morning it will not turn at all.

The cylinder feels loose or wobbly

Play in the plug or the housing means the assembly is moving in the column. This is mechanical wear, not electronics, and it gets worse on its own.

The wheel will not release even with the key out

On most vehicles that is the column lock pin. On a Mercedes with an Electronic Steering Lock, or on a Nissan with a steering lock actuator, it is a module, not a pin.
What This Symptom Is Not

Four things people get quoted for by mistake

A key that will not rotate rules several expensive repairs out before anyone opens a toolbox. Knowing which ones protects you on the phone.

It is not the immobilizer

On a mechanical ignition the immobilizer only reads the transponder once the key turns, so a key that never rotated never reached it. Not true of the electronic ignitions in the table below (Mercedes ESL, Nissan actuator, RAM WIN), which authorise before they release.
Mechanical ignitions

It is not a dead battery

A flat battery kills the crank, not the rotation: a mechanical lock cylinder turns with the battery disconnected entirely. On the electronic steering locks in the table below, low voltage is a live cause, because the module must be powered to release.
Mechanical ignitions

P0513 is a different symptom

P0513, Incorrect Immobilizer Key, is a real code, and it belongs to a key that turns and then fails to start the engine. It is not a code for a key that will not rotate.
Scope it correctly

It is not module programming

ECU, BCM, PCM and TCM faults, including communication codes like U0100, live behind a working ignition. Real work, different page, not this symptom.

What this looks like on the cars we actually work on

These are the makes, models and year spans behind our own ignition work, not a list of prestige badges. The mechanism is not the same on all of them, and that changes what you should try first.

Honda Accord1998-2019HON66 wafer cylinderMechanical column lock. Free the wheel first. If both keys fail, the cylinder comes out on site.
Honda Civic2010-2022HON66 wafer cylinderSame column lock behaviour as the Accord. Worn-key failures are common at this age.
Honda CR-V2003-2014HON66 wafer cylinderHigh-mileage wafer wear. Key cut to code, or cylinder replaced and re-keyed to the existing key.
Toyota Corolla1999-2018TOY43 wafer cylinderColumn lock plus a wafer stack that wears predictably. Decoded and cut on site.
Toyota Camry2008-2020TOY43 wafer cylinderLater trims are push-to-start, where the symptom is a wheel that will not release, not a key that will not turn.
Chevrolet Silverado2015-2023B111 / B106 keywayColumn lock plus cylinder. Truck weight on a turned wheel loads the lock pin hard, so rock the wheel properly before calling.
Chevrolet Malibu1999-2017B111 / B106 keywayOlder GM cylinders and sidebar-era hardware. Cylinder replaced and keyed on site.
Ford F-1502012-2020Blank decoded on siteFord changed blade profile inside this span, so we decode the lock rather than publish one code for all of it. Worn blades fail to lift the wafers long before the key looks worn.
Ford Explorer2009-2020Blank decoded on siteFord changed blade profile inside this span, so we decode the lock rather than publish one code for all of it. Cut to code from the VIN with proof of ownership.
Volkswagen Jetta2007-2020HU66 keywayColumn lock plus a cylinder that binds as it wears. Cut to code, cylinder swapped if it is the plug.
Hyundai Sonata2008-2017Blank decoded on siteWe decode the lock rather than publish a blank code we have not verified. Cylinder or key, diagnosed in the driveway.
Nissan Rogue2011-2023Blank decoded on siteSteering lock is commanded by the BCM through an actuator, not a plain mechanical pin. Rocking the wheel will not free it if the actuator is the fault.
Nissan Altima2014-2021Blank decoded on siteSame actuator-based steering lock. We confirm whether the block is mechanical or commanded before touching the column.
Mercedes-Benz C3002010-2022HU64 keywayW204 and W205 use an Electronic Steering Lock (ESL, also ELV). There is no pin to rock free. Module-level work, coded to the car, NASTF VSP required.
BMW 535i2010-2017Blank decoded on siteCAS immobilizer family. Column lock behaviour differs from a plain wafer cylinder and is diagnosed as a module, so the blade profile is read off the lock rather than published.
RAM 25002012-2025CY24 keywayLater trucks use a WIN module (Wireless Ignition Node) in place of a conventional cylinder. Different part, different diagnosis.

Keyway codes are published only where we are confident of them. Where we are not, the row says the blank is decoded on site rather than guessing. Same rule for fault codes: the Nissan steering lock actuator and the Chrysler WIN module both have documented failure patterns, so we describe the mechanism and leave the code numbers off the page.

*Prices shown are reference only. Final cost varies based on the complexity of the service, the specific hardware involved, the vehicle make, model and year, and the time of service. We provide an exact phone quote before our technician is dispatched. Automotive prices depend on the make, the model and the year of the vehicle. A key for a Toyota and a key for a Ferrari are not the same job, and the ranges above reflect that spread. The dispatcher confirms the exact total on the phone before a technician is sent.

How We Work

What you should expect from whoever you call

We ask for proof of ownership

Before any key is made when no working key exists, we need the title, the registration or the insurance in your name, plus photo ID that matches it. A locksmith who does not ask is the warning sign, not the convenience.

Work vans and light trucks included

Keys cut and programmed for commercial vehicles, Sprinter 2500 and Savana work vans among them, not only passenger cars.

Fixed where the car is parked

The cylinder comes out in your driveway or the parking lot. A locked column is exactly the case where towing costs the most, because the wheel will not straighten for the tow.

The quote is set before dispatch

The dispatcher gives you the total on the phone, including the after-hours surcharge if it applies, before a technician leaves.

FAQ - Key Will Not Turn in the Ignition

Got questions? We have answers. If you don't see your question below, call us anytime - we're available 24/7.

Take the pressure off the key, then put light, steady turning pressure on it while you rock the steering wheel gently left and right. In most cases the steering column lock pin is loaded against its slot and the plug cannot rotate until that load comes off. This is free and it usually takes under a minute. If the wheel does not move at all, check that the shifter is fully seated in Park, then try your spare key.
Almost certainly. A spring-loaded lock pin drops into the steering shaft when you remove the key. Parking with the wheel turned, or with a front tire against a curb, puts the weight of the car on that pin and jams it in the slot. The cylinder is fine. Rock the wheel while applying light key pressure and it releases.
No. A key blade shears at the shoulder under far less torque than people expect, and a broken blade inside the plug turns a free fix into a broken-key extraction, which runs $100 - $250 by day. Rock the wheel instead. The correct amount of key pressure is about what you would use on a house key.
It means the cylinder is fine and your everyday key is worn. The cuts have lost depth and no longer lift the wafers to the shear line. Do not have that key copied, because a copy reproduces the worn cuts and fails the same way. The correct fix is a key cut to code from the VIN, or cut from depths decoded off the lock itself.
It means the key is not the variable, so the fault is in the ignition lock cylinder or in the steering column. Worn wafers, a failed spring, a seized plug or a stuck column lock all present this way. A technician confirms which on site before anything is removed, and the repair starts from $200.
One. If the key never rotated, the starting circuit was never asked to do anything, so there is nothing separate wrong with it. Fix the rotation and the starting behaviour usually comes back with it. If the key rotates normally and the engine still does nothing, that is the opposite symptom and a different diagnosis.
No. A key that will not rotate is a mechanical failure and sets no diagnostic trouble code, because the ignition never reached START and the engine control module was never asked to act. There is nothing for a scan tool to read. P0513, Incorrect Immobilizer Key, is a real code but it belongs to a key that turns and then fails to start the engine.
Yes, and it is the second most common free cause. The shift interlock ties the ignition to the shifter position, and a lever that is one notch short of fully seated, or a worn park position switch, will hold the key. Push the lever firmly into Park. If nothing changes, hold the brake, move it to Neutral, and try the key there.
An automotive locksmith, in almost every case. The failure is in the lock cylinder, the key or the steering column lock, which are lock components. A mechanic is the right call when the key turns normally and the engine does not respond, because that moves the fault into the electrical and starting side.
Where it is parked. We remove the column trim, replace the cylinder and re-key or cut to match on site, then test rotation, crank, steering release and key removal before we leave. A locked column is the worst case for towing anyway, because the wheels will not straighten.
Usually not. W204 and W205 C300 models use an Electronic Steering Lock (ESL, also called ELV), which is a module rather than a mechanical pin, so rocking the wheel does nothing. That is module-level work, coded to the vehicle, and OEM data access for it requires NASTF VSP authorization. We are VSP authorized, and we tell you on the phone which branch you are on.
Proof that the vehicle is yours: the title, the current registration or the insurance in your name, plus photo ID that matches it. We ask every time, including on work vans and trucks. All-keys-lost programming runs $200 - $1,000 depending on the vehicle, and the dispatcher confirms the exact total on the phone before a technician is sent.
