🔑 Step-by-Step: Manual Key Programming (Toyota FJ Cruiser)
- Insert your master key into the ignition (do not start engine).
- Turn the ignition ON and OFF five times within 15 seconds.
- Leave the ignition OFF after the final cycle.
- Open and close the driver’s door six times within 20 seconds.
- You should see the security light illuminate — this means the system is in programming mode.
- Insert the new key into the ignition.
- Turn ignition to ON (without starting engine) and leave it for about 60 seconds.
- The security light will stop flashing, confirming the key is accepted.
- Turn ignition OFF and remove the new key.
- Test the new key by starting the engine.
⚠️ Troubleshooting
- Security light keeps flashing → Your key may not be compatible or you used a valet/sub key instead of a master key.
- New key won’t start vehicle → The transponder chip may not be programmed correctly.
- Procedure won’t enter programming mode → Timings must be precise; repeat steps carefully.
If the issue persists, the immobiliser ECU may need to be programmed with specialist equipment.
