Toyotas used to use traditional keys made of steel to unlock doors and also start the engine. However, times have changed and today, many vehicles use key fobs to do the job.
If you own a Toyota that requires a key fob, it's crucial to know the different types available and their functions.
Transponder Keys
Transponder keys are the most commonly used type of car keys. They use a microchip to communicate with the car's computer system and transmit a unique security code. These keys are designed to ward off unauthorized access, which is why they're so difficult to duplicate. They're also more expensive than traditional keys. Here's a quick overview of how they function.
Transponder keys typically include a plastic piece to house the microchip. The chip appears like a regular key, but it is slightly larger than a conventional key due to the fact that it needs to hold the microchip. The plastic piece is affixed to the base of the key and is evident when you look at it closely. The chip transmits a security code to vehicle's onboard computers, which will then check the code against an immobilizer system. If the codes are the identical the engine will start. If not the onboard computers stop the vehicle from beginning, making it almost impossible for thieves to wire the vehicle.
This technology makes it much more difficult for thieves to steal vehicles, but it's not completely foolproof. This is also useful for those who do not want to accidentally lock their car keys in their vehicle. However, there are still ways for thieves to bypass this security feature.
Whatever type of key you have regardless of the type, you must be aware of the possible risks associated with them. If you're worried about someone stealing your car, you should consider upgrading to a transponder key or a proximity key. These keys are more expensive and require professional programming.

Key Fobs
Key fobs are small device that opens your car doors, trunk and starts the engine. It also houses a panic button that can be used to notify your vehicle's emergency response system in the event of an accident or are in danger. In contrast to physical keys made of metal, key fobs use radio frequency technology to communicate with your vehicle.
A receiver that is mounted on the dashboard of your Toyota receives signals transmitted by the key fob, and then decodes them to unlock doors and start the vehicle. A rolling code is generated every when you press the fob's button, making it very difficult to duplicate these signals. The rolling codes also prevent hacking since the sequence of codes is constantly changing and cannot be recorded and replayed.
The majority of the newer Toyotas include key fobs that have the "find my car" feature. The fob will send a signal to your car when you are within the range of the fob, which will allow you to locate your car even when you have lost it. This can be helpful if you're trying to find your car in a parking space or on a busy street.

Smart Keys
