The Toyota keyless entry system is a convenient feature available on some new Toyota vehicles. With this keyless fob on your person or in your purse, you can start the engine, unlock the doors, and do anything else that normally requires a key.

To start the automobile, lock and unlock the doors, and do other tasks, the Toyota keyless entry system uses wireless technology to “recognize” when the key is near the vehicle. Here’s how the keyless entry system in your Toyota works:

  • To open a locked car door when using a keyless remote, simply grab the door handle. The system will recognize the key, and the door will automatically open.
  • As soon as you enter your vehicle and press the button on your keyless remote, the engine will be ready to go. To begin driving, apply the brake and push the “Start/Stop” button.
  • Safety features built into the Toyota keyless entry system make it difficult to lock your keys inside the vehicle accidentally. If you leave your keyless remote inside the car and then try to lock the doors by pressing the “lock” button on the door handle, an alarm will go off to let you know that you need to get your keys.
