Car Key Won't Turn in the Ignition: Causes and Fixes

The usual culprit is the steering column lock gripping the cylinder. Rock the wheel gently toward the side with some give while you turn the key, and both tend to release together.

A key that slides all the way in and then will not rotate is usually being held, not broken. The steering lock, the key, the cylinder and, on keyless cars, the fob are the usual suspects, listed below with the likeliest first.

The first and last are often solved in the driveway for little or nothing. A worn key or cylinder needs a paid fix, and the ignition repair page walks through the cylinder job.

Programming happens through the port under your dash.

Try this first

  • Rock the steering wheel gently toward the side with some play while turning the key with light hand pressure.
  • Put the spare in. If it turns, the daily key is the worn part.
  • If the key will not return to Lock, press the brake and check that the shifter sits fully in Park.
  • On a twist-knob car, swap the fob's coin cell for a new one, often a CR2032.
  • Check the blade for a bend or a hairline crack, and stop turning if you see one.

Most likely causes, in order

  1. The steering lock is pinning the cylinder

    Tell-tale sign: the key seats fully but will not budge, and the wheel is locked hard in one direction. Turning the wheel after the engine is off, as when you curb the tires on a steep street in Golden Hill, loads the lock pin against its notch, and the pin holds the cylinder too. Fix: rock the wheel toward the side that moves while turning the key lightly.

  2. The key has worn smooth

    Tell-tale sign: the spare turns cleanly and the daily key does not, or the daily key works only after a few jiggles. Years on a ring round off the peak of every cut, so the wafers stop short of the height that frees the cylinder. Fix: a new key cut to factory depths by code, since a copy traced from the worn blade inherits its wear.

  3. Worn wafers in the lock cylinder

    Tell-tale sign: every key for the car sticks, and the trouble crept up over months. The cylinder's wafers drift out of line with the housing after years of daily turns, and once a freshly cut key also refuses, the lock is what has given out. Fix: a new cylinder, set at the car to your current key, so a single key still works the doors and the ignition.

  4. A twist knob that cannot hear the fob

    Tell-tale sign: there is no keyhole, only a knob, and it stays locked while a key symbol may flash on the dash. These ignitions free the knob only after the car detects the fob, and a cell running low usually explains why it does not. Fix: a fresh cell, often a CR2032. A backup spot shown in the owner's manual tells you quickly whether the cell was at fault.

Known problems by make

If your car is one of these, the make page is the faster read: it names the years, the part that fails and what the repair costs.

Honda ignition repair

Many Honda and Acura ignitions built from 1998 on develop worn or broken wafers, and the key sticks or will not turn.

Volkswagen ignition repair

On 2005 to 2016 Jettas and 2012 to 2016 Beetles the lock housing fails and the key sticks; 2006 to 2010 Passats have an electronic steering lock...

Kia and Hyundai theft ignition repair

Many 2011 to 2022 turn-key Kias and Hyundais lack an immobilizer, and a theft attempt leaves the lock cylinder and housing broken.

Dodge and Chrysler key won't turn

On 2008 to 2014 Chrysler, Dodge, Jeep and Ram models with a push-in fob key, wear in the ignition node can stop the key turning or being read.

Chevy and GMC truck ignition repair

Chevy and GMC trucks and SUVs from 1999 to 2014 wear out ignition cylinders and keys until the key stops turning.

Ford Escape and Focus ignition repair

On 2008 to 2012 Escapes and 2000 to 2011 Focus cars, worn ignition parts stop the key from turning or reaching Start.

Mercedes key won't turn

On the 2008 to 2014 C-Class and some GLK and E-Class cars of the same era, a failed steering lock lets the key in but not turn.

Car key problems by make, and what each dash message means

When to call

Call once the wheel moves freely and the key still refuses, or when the spare sticks as badly as the daily key. The fault is then inside the cylinder, and more twisting mostly risks a snapped blade. Tell us the car and which positions the key still reaches, and the price is set before we drive.

Call as well if the key turns fully but the engine does not crank. That points past the lock to the ignition switch, the starter motor or a flat battery, and we sort out on the call which is a mechanic's job before anyone drives out.

What the fix costs

From the same price sheet as every other job. Confirmed on the phone before we drive.

Questions people ask

Why does my key go in the ignition but not turn?

Usually the steering lock pin is pressing on the cylinder. Rock the wheel gently toward the side with some give while you turn the key, and both should release together. If the wheel moves freely and the key still stops, try the spare: a spare that turns means a worn key, and two stuck keys mean a worn cylinder.

What does it cost when the key will not turn?

Anywhere from nothing to $349, depending on the part. A worn key means a new chip key, $125 to $199 where you parked, while a dealer asks $230 to $380. A worn cylinder is replaced and set to your key for $179 to $349; the dealership quote is $350 to $700.

Will a hardware store key copy fix it?

Usually not. A copy traced from a worn key inherits its rounded cuts and binds the same way. Most cars from 1998 onward also read a chip before starting, so a blade-only copy can turn the lock and leave the engine silent. A code-cut key with a programmed chip avoids both.

Can I keep driving if the key only turns some of the time?

You can, but book the repair soon. A cylinder that needs several tries tends to get worse, ending with a morning when it refuses entirely or a key that snaps mid-twist. Replacing it while the car still runs lets you pick the time and the place, with no tow either way.

What if my car has a knob instead of a key slot?

Then the car has to sense the fob before the knob unlocks, and a fob cell near the end of its life is the likely cause. Fit a fresh cell, often a CR2032, and try the backup fob position shown in the owner's manual. If the knob stays locked with a fresh cell, call and tell us what the dash displays.
