Starting problems

Key won't turn in the ignition

If the key won't turn at all, the problem is usually mechanical - a locked steering column, a worn key, or a stuck ignition cylinder - rather than an electrical no-start.

Symptoms

  • Key goes in but won't rotate
  • Steering wheel feels locked
  • May work if you jiggle the wheel or key
  • Sometimes only happens with one specific key

Likely causes

  • CommonSteering wheel lock engagedMost cars lock the column when the wheel is turned while parked, and the key won't turn until pressure is released.
  • CommonWorn or damaged keyA worn key can fail to fully engage the tumblers needed to turn the cylinder.
  • PossibleDirty or worn ignition cylinderDirt or wear inside the lock can prevent smooth rotation.
  • PossibleSteering column shift interlock not engaged (automatic)Some vehicles require the shifter to be fully in Park before the key will turn.
  • PossibleFailing ignition lock cylinder or tumblersOver years of use the internal pins can wear enough to bind.

What to do

  1. Make sure the shifter is fully in Park (automatic) or the clutch is pressed (manual, if required) before turning the key.
  2. Gently turn the steering wheel left and right while applying light pressure to the key to release a locked column.
  3. Try your spare key if you have one, in case the primary key is worn.
  4. Avoid forcing the key hard, which can bend it or damage the lock cylinder.
  5. If the key turns partway then binds, try lightly wiggling it up and down while turning.
  6. Spray a small amount of graphite or a lock-specific lubricant into the keyhole if the lock feels gritty (avoid oil-based lubricants, which attract dirt).
  7. If it's a push-button start car with a separate lock issue, check the owner's manual for the steering lock release procedure.
  8. If nothing works, avoid repeated forceful attempts, which can snap a key off in the lock.

Tools and parts

  • Spare key if available
  • Dry lock lubricant (graphite or specific lock lube)

When to call a pro

If wiggling the wheel and trying a spare key don't work, a locksmith or dealer can service or replace the ignition cylinder without towing in many cases.
