ο»Ώο»Ώο»Ώο»ΏA worn or failing ignition switch is a common cause of no start, sudden stalling, or dead accessories. The good news: you can spot the signs early and do a few easy checks at home before deciding to replace it.

Quick symptoms of a bad ignition switch

  • No crank when you turn the key to START (but the battery is good).
  • Intermittent starting: jiggle the key and it suddenly works.
  • Stalling while driving, especially when the key is bumped.
  • Accessories cut out (radio, HVAC, lights) when you move the key.
  • Key feels loose or gets stuck; visible wear on the cylinder.

Simple tests you can do

  1. Battery and fuses first: rule out low voltage and blown fuses.
  2. Accessory position test: turn to ACC. If radio and blower flicker when you nudge the key, suspect the switch.
  3. Wiggle test: hold the key in RUN and gently wiggle. If the engine cuts or accessories die, contacts inside the switch may be worn.
  4. Starter relay bypass: if the starter cranks when you jump the relay, but not with the key, look at the ignition switch or neutral safety circuit.

Replacement cost (typical)

  • Ignition switch: $45–$120 for quality brands; labor 0.7–1.5 hr.
  • Lock cylinder (if needed): $60–$150; labor 0.5–1.0 hr.

Prices vary by vehicle and brand; always verify fitment.
