Sometimes, car owners may notice the security light on their Toyota dashboard flashing, which can be concerning. But don’t panic just yet! There could be several reasons for this issue. One common cause is an incorrect key code. If the car doesn't recognize the key, it might trigger the security system. Another possibility is a malfunction in the immobilizer system. This system works to prevent unauthorized starts by matching the key code with the car’s system. If there’s any disruption, the security light will blink as a warning.

To troubleshoot, try using the original key and ensure it’s not damaged. If the problem persists, check the battery of your key fob—low power can sometimes cause issues. For peace of mind, visiting a certified Toyota mechanic is always a good idea. They can run diagnostic tests to pinpoint the exact issue. Remember, it's better to get it checked early than to risk further complications. Keep calm and drive safe! ✅交通安全，你我同行！
