Programming
🏢 Dealer RequiredProgramming typically requires a compatible scan tool and security authorization/credentials used for late-model Toyota immobilizer systems. Some situations (all keys lost, immobilizer/Smart Key ECU replacement, or certain security states) may be dealer-only or require a locksmith with advanced Toyota support. Expect proof of ownership and photo ID to be required by reputable providers.
⚠️ Common Issues
- Weak coin-cell battery causing reduced range or 'Key Not Detected' messages
- Aftermarket fobs that look correct but have incompatible FCC ID/frequency or chipset
- Fob works for remote buttons but not for proximity/start due to incomplete smart registration
