How to check and replace the ignition switch and Ignition Lock Cylinder on 1995 through 2004 Toyota Tacoma?

After disconnecting power, disable airbags and remove steering wheel components to get access by taking off protective steering column shields.

Test the key unlock warning switch between OFF mode and the key removed until you find no connection between the two terminals. Insert your key and turn the switch ON to validate 1 and 2 terminal connection. The replacement of ignition switch becomes necessary when manual operation fails. First insert the key into the ignition switch Ignition Lock Cylinder then switch it to ACC mode. Next follow this step by inserting a small screwdriver to depress the release button while pulling the lock cylinder straight out. The process to install a part follows the opposite steps of when you took it out.

Toyota Tacoma Ignition Switch

The Ignition Switch of Toyota Tacoma sends electrical current from the battery to the starter, ignition, and component circuits. The Ignition Switch, fixed on the steering column, enables switching only when the matching key is inserted. This arrangement is in accordance with Toyota anti-theft strategy. The Tacoma Ignition Switch must be turned to the start position to engage power from the battery to the starter motor and fuel systems for engine cranking. The on position energizes the engine and electrical components when running. The Toyota Tacoma operator can power the radio and other items without running the engine via an acc position. The power to the Ignition Switch is cut, and the steering will be secured in the lock position, and the key can be removed. Automatic-equipped Tacoma will always have the shift lever in park. A coded key relays information with the onboard electronic components with which the vehicle is fitted to restrict the engine of any Toyota from starting when the code is rejected. Damage caused by wear or internal contact inside the Ignition Switch can cause both intermittent component loss and unexpected engine shutdown.
