Ignition Switch

Automotive Ignition Switch and Lock Cylinder Assembly
Engine Starting & Electrical Circuit Control

OEM Ignition Switches & Lock Cylinder Modules

Restore reliable engine starting, accessory power activation, and key cylinder turning smoothness with our pre-tested OEM ignition switches.

The ignition switch routes battery power to the starter solenoid, ignition coils, fuel pump, and dashboard accessories based on key position. Pitting contacts, worn internal tumblers, or faulty push-button start modules can result in sudden engine stalling, intermittent starter engagement, or key sticking. Our replacement ignition assemblies feature heavy-duty electrical contacts, anti-theft immobilizer chip compatibility, and direct-fit electrical harness plugs.

Common signs include engine stalling unexpectedly while driving, key failing to turn in the lock cylinder, dashboard warning lights failing to illuminate in the "ON" position, and starter not engaging when turned to "START".

The lock cylinder is the mechanical key tumbler mechanism where your metal key inserts. The ignition switch is the electrical component mounted behind it that connects electrical contacts as the cylinder rotates.

Replacing the lock cylinder comes with new matching keys, or the new cylinder tumbler pins can be re-keyed by a locksmith to match your existing door keys. Replacing only the electrical switch behind it keeps your original keys.

Yes! Hanging heavy keychains creates constant downward leverage while driving over bumps, which prematurely wears out mechanical lock tumblers and internal electrical contacts.

Always disconnect the battery negative terminal before working on ignition electrical components to prevent accidental airbag deployment or wiring harness shorting.
