Toyota FJ Cruiser Key Programming Procedure (Manual Method)
Need to program a new key for your Toyota FJ Cruiser? Whether you’ve bought a spare, replaced a lost key, or need to re-sync your immobiliser, this guide covers the manual programming steps that work on most FJ Cruiser models sold in Australia.
✅ What You’ll Need
- Your Toyota FJ Cruiser with at least one working master key
- The new key blank or transponder key to be programmed
- A few minutes of uninterrupted time
🔑 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.

Professional Tip
Some Toyota FJ Cruiser models will appear to complete the manual programming sequence but fail due to:
- Immobiliser system restrictions
- Incorrect remote type or frequency
- Vehicle battery voltage issues
- Aftermarket alarm or immobiliser interference
If manual programming fails, a diagnostic scan can quickly confirm whether key registration is supported on your specific vehicle.
💡 When DIY Won’t Work
Manual programming requires at least one working master key. If you’ve lost all keys, the vehicle must be programmed using diagnostic locksmith tools.
