How Does the Ignition Lock Cylinder Work in Your Car?

Before we dive into replacement costs, let’s overview what the ignition lock cylinder does:

  • It contains a set of spring-loaded tumblers that must align with cuts in your key when inserted. This allows the ignition switch to activate.
  • When you turn the key, it rotates the cylinder. This enables the switch to send power to the starter and ignition system.
  • The cylinder provides physical security by requiring the correct key to start the vehicle.
  • It helps prevent hotwiring and theft when functioning properly.

So in short, the lock cylinder is the crucial mechanical gatekeeper between your key and actually starting the engine.

  • Keys Breaking Off – Severe cylinder damage can cause keys to snap and get stuck inside.

Don’t delay cylinder replacement when these symptoms appear. Doing so can leave you stranded.
