Toyota 69057-35240 Ignition Lock Cylinder

Removal steps 1. Park vehicle on level ground, set parking brake, remove key/fob from ignition, and note/disable any active alarm or immobilizer per owner's instructions. 2. Disconnect the negative battery terminal and isolate the cable; wait the manufacturer-recommended time for SRS/unpowered systems to de-energize (commonly a few minutes). 3. If work is near the steering column airbag or clockspring, follow airbag safety practices and avoid deploying the airbag or rotating the steering wheel while connectors are disconnected. 4. Remove or open any trim or column covers that block access to the ignition lock area-use appropriate trim tools to avoid damage and keep fasteners/clips organized. 5. Photograph or mark the relative positions of linkages, electrical connectors, and any actuator/lock orientation for reassembly reference. 6. Disconnect electrical connectors attached to the ignition lock assembly; label connectors if multiple similar plugs are present. 7. Release any retaining clips, retaining rings, or locking tabs securing the lock cylinder/assembly-note that the release method varies by design. 8. Withdraw the lock cylinder or entire ignition lock assembly gently, guiding wiring and linkages free; retain small springs or tumblers if present. Installation steps 1. Verify replacement part matches original and that you have required keys or programming credentials before installing. 2. Position the lock cylinder or ignition assembly into place, aligning it to the same orientation noted during removal; ensure linkages are routed without binding. 3. Reinstall retaining clips, rings, or fasteners to secure the assembly-use the original hardware where possible and keep components seated correctly. 4. Reconnect all electrical connectors and any mechanical linkages, confirming each connector locks in place and wiring has clearance from moving parts. 5. Refit trim and column covers, reinstalling fasteners or clips and ensuring no wires are pinched. 6. Reconnect the negative battery terminal and clear any stored codes or warnings only if you have the correct diagnostic tool and instructions; wait briefly for systems to power up. 7. Test operation: verify key or push-button functions, accessory positions, engine start/stop, steering lock/unlock, and that warning lamps behave normally; if the vehicle has an immobilizer or transponder, confirm the key is recognized or perform required programming. 8. If any binding, electrical faults, airbag warnings, or immobilizer issues occur, stop and consult a professional with the appropriate diagnostic tools. Repair tip: Keep small springs, tumblers, and clips in labeled containers during the job and take reference photos before disassembly to simplify correct reassembly.
