Toyota Keys and Transponder Keys Toyotas used to use traditional keys made of steel for unlocking doors and starting the engine. However, times have changed and today, many vehicles utilize key fobs for the job. It's important to know the different types of key fobs and how they function in the event that you have a Toyota. Transponder Keys Transponder keys are the most common type of car key.

They're also more expensive than regular keys. Here's a quick overview of how they work. Typically transponder keys are constructed using a plastic component that houses the microchip. The chip is shaped like a standard key, but slightly larger because the microchip must be able to fit. The plastic piece is affixed to the key's base and is evident when you look at it carefully. The chip sends an immobilizer code to the onboard computer of the vehicle. If the codes match, identical then the engine will start. If the codes don't match, the computer onboard will prevent the vehicle getting started, making it impossible for thieves to wire the car.

Key Fobs A key fob, also known as a remote control is a small device used to open the doors of your vehicle or trunk, and also to start the engine. It also has an emergency button that can be used to contact your vehicle's emergency response system in the event of an accident or are in danger. Unlike physical metal keys, key fobs use radio frequency technology to communicate with your vehicle. A special receiver mounted located on the dashboard of your Toyota detects the signals sent by the fob that you have and decodes them to open the doors or start the engine. Each time you press the button on your fob a rolling code is generated. This makes it very difficult to copy or duplicate these signals. The rolling codes also prevent hacking since the sequence of codes is constantly changing and cannot be recorded or replayed.

The fob will send a signal to your vehicle whenever you come within the range of the fob, allowing you to locate your car even when you've lost it.

Some models even allow you to use the lock button while your Toyota is in park to disable the puddle or courtesy lights making it more difficult for thieves to steal your car. Certain smart keys also save your driver profile settings for seat position, climate control, and more. Then, each time you get into your car it will automatically adjust to your preferred settings. This feature is ideal when you have multiple drivers for your Toyota and you want to ensure that everyone's comfort level is satisfied.
