If your vehicle is showing physical key gets stuck or won't turn in door lock cylinder, here are the most likely causes and the parts you'll need to fix each one.
Because most drivers rely on electronic key fobs, the physical door lock cylinder rarely gets used. Over time, dirt, dust, and corrosion build up inside, causing the internal tumblers to seize.
The cuts and grooves on the physical key blade can wear down and become too smooth over years of use, failing to properly align the pins inside the lock cylinder.
The internal wafers or pins inside the lock cylinder have bent, broken, or worn out. This physically blocks the cylinder from rotating even with the correct key.
In freezing temperatures, moisture trapped inside the door lock cylinder can freeze into ice, locking the internal tumblers solid and preventing the key from turning.
If the door panel was recently removed for repairs, the metal linkage rod connecting the lock cylinder to the door latch may have been bent, misrouted, or jammed, preventing the cylinder from turning.
