Q: How do you remove and install the ignition switch and lock cylinder on Toyota Avalon and 2002 through 2008 Toyota Solara?
A: These models are equipped with an integration relay that works in conjunction with the ignition switch to activate the key unlock warning system and anti-theft system. To remove the ignition switch, first disconnect the cable from the negative terminal of the battery and place the ignition key in the ACC position. Then, remove the steering wheel and steering column covers. Unplug the ignition switch electrical connectors and remove the switch retaining screws to detach the electrical portion of the ignition switch from the lock cylinder housing. To remove the lock cylinder, disconnect the electrical connector from the key-lock warning switch and, if applicable, gently pry off the plastic shroud around the Ignition Lock Cylinder and disconnect the electrical connector. Depress the lock cylinder retaining pin with a small screwdriver or punch and pull the cylinder straight out. To install the lock cylinder, depress the retaining pin and guide the lock cylinder into the housing until the retaining pin extends itself back into the locating hole. The remaining steps for installation are the reverse of removal.
Q: How to disconnect and remove the ignition switch,Ignition Lock Cylinder and steering lock actuator assembly?
A: Disconnect the cable from the negative battery terminal. Place the ignition key in the ACC position. Remove the steering wheel. Remove the steering column covers. Remove the steering column switches. Unplug the ignition switch wiring harness connector and key light connector (if equipped). Remove the interlock solenoid mounting screws and disengage the ignition switch mounting clips, then pull the switch from the housing. Installation is reverse of removal. Carefully pry the transponder key amplifier switch mounting clips outwards and slide the transponder forward to detach it and the bracket from the steering column. Turn the ignition switch to ON (ACC). Use a small screwdriver or punch inserted into the hole in the top of the steering column bracket to depress the locking claw and pull the Ignition Lock Cylinder out until its claw comes into contact with the stopper of the steering column bracket. Insert the tip of a screwdriver into the hole inside of the steering column bracket and tilt it downward to disengage the claw. Pull the Ignition Lock Cylinder out. The remainder of installation is the reverse of removal. After replacing the steering lock actuator assembly, perform the key ID code registration by opening and closing the driver's door. The engine may not start until the driver's door has been opened and closed. Remove the steering column and place the column in a soft jaw vise. Using a grinder or small hacksaw blade, cut a slot into the steering lock shear bolt heads. Use a screwdriver to back the bolts out and remove the actuator. Install the steering lock actuator and steering column clamp with new steering lock shear-head bolts, then tighten the bolts until their heads break off.
Q: How do I perform a check, removal, and installation of the ignition switch and lock cylinder on Lexus ES300,Toyota Avalon and 1997 through 2001 Toyota Solara?
A: To check the ignition switch, follow these steps: Trace the wire from the ignition switch to the main wiring harness connector and disconnect it. Then, use an ohmmeter or self-powered test light to assess continuity between the specified switch terminals in different switch positions. If continuity doesn't match the specified values, replace the switch. For ignition switch removal, begin by disconnecting the battery's negative terminal cable and placing the ignition key in the ACC position. Proceed to remove the steering wheel and steering column covers. Then, take out the steering column switches and unplug the ignition switch wiring harness connectors. Detach the switch retaining screws and remove the switch assembly from the steering column. Installation involves reversing the removal process. To remove the Ignition Lock Cylinder, depress the Ignition Lock Cylinder retaining pin using a small screwdriver or punch, then pull the Ignition Lock Cylinder straight out from the vehicle. To install the Ignition Lock Cylinder, depress the retaining pin and guide the Ignition Lock Cylinder into the steering column housing until the retaining pin locks into the locating hole. The rest of the installation process is the reverse of the removal steps.
