Keyfob problem on Toyota Yaris hybrid

[Angie0823]

I have a problem with my keyfob. I can't used it to unlock my car anymore. I have to use the key. And I can only start my car with the keyfob over the start/stop button. Because it is a keyless start. But after the car is started, whoever is entering my car or exiting my car, my car will start to bleep and an orange key symbols will appear on the dashboard. Meaning something is wrong with the emobolizer in the car. I thought it was the Battery of the key. So I tried using my spare key that I have never used before on it. But that wouldn't unlock the central lock either. So I changed the Battery in both keyfobs. But it still doesn't work. Very frustrating and annoying. Can anyone tell me the problem please ? 😭 🥺

Hi, 

your keys needs re introduction ( reprogram) to the car. 
It’s a simple procedure that you need to follow.

Thanks Tony for the link. But mine is a keyless start car. So not sure if I can do that. I did see it on YouTube with the actual key in the ignition. But I don't have a key

You do same steps but instead of turning key in ignition you just press twice start button without stepping on the brake pedal. All lights come on but no car starts. Do that and likely will work. Make sure you follow steps. After you do one key , then try the other and if not working you run the same process. 
After that make sure that you use both remote at least once every two months. You not gonna have any problems again. 👍
