Toyota’s smart key system is designed to provide convenience and ease of use for drivers. With this system, you can unlock, lock, and operate your vehicle without even taking the smart key out of your pocket or purse. In this article, we will delve into the details of Toyota’s smart key system, its features, and how to use it effectively.

Unlocking and Locking the Doors

One of the key functions of Toyota’s smart key system is the ability to unlock and lock the doors without physically using the key or pressing any buttons. To unlock the door, simply grip the door handle while carrying the smart key. The lock sensor on the back of the handle will detect your touch and unlock the door. On certain models, holding the driver’s door handle for about two seconds will unlock all the doors, signaled by a beep and flashing four-way flashers.

It’s important to note that the sensor may not activate if you’re wearing gloves, so make sure to remove them before attempting to unlock the door. Additionally, on some models, opening the front passenger’s door will automatically unlock all the doors.

If you prefer to customize the smart key system to unlock all the doors when either front door handle is gripped, you can easily program it. Press and hold the lock button while holding the unlock, back door release, or panic button for approximately five seconds. Repeat the same steps to revert back to the default setting. This programming can also be done through the multimedia system screen or by visiting a Toyota dealer.

Convenient Features

Toyota’s smart key system offers additional convenient features. Pressing and holding the unlock button for five seconds will open all the windows and sunroof. This feature comes in handy during hot weather, as it allows you to cool down the vehicle’s interior before getting in. However, it’s important to note that this feature needs to be activated by a Toyota dealer.

When exiting the vehicle with the smart key and closing all the doors, locking the doors is as simple as touching the lock sensor on the upper part of the driver’s door handle. A beep will sound, and hazard lights will flash once to confirm that the doors are locked.

Emergency Backup Key and Smart Key Malfunction

In case of a smart key malfunction or a depleted smart key battery, Toyota provides an emergency backup key within the smart key fob. This mechanical key can be used to manually lock or unlock the vehicle. To start the vehicle in such situations, depress the brake pedal and hold the smart key against the front of the start/stop engine switch. An indicator light in the switch will turn green, and a buzzer will sound, giving you approximately 10 seconds to push the engine switch and start the engine.

If you’re experiencing a smart key malfunction or need to have the smart key remote battery replaced, it is advisable to visit a Toyota dealer. They will inspect the smart key system and replace the battery if necessary.


Toyota’s smart key system offers a convenient and hassle-free way to unlock, lock, and operate your vehicle. With the ability to perform these tasks without physically using the key, you can easily access your car and enjoy a seamless driving experience. Make sure to utilize the programming features and take advantage of the emergency backup key in case of any issues. For any smart key system concerns, it’s always best to consult with a Toyota dealer for professional advice and assistance.
