If you have a Toyota that requires a key fob it's essential to know the different types available and their functions. Transponder Keys Transponder keys are among the most common kinds of car keys.

They also cost more than standard keys. Here's a quick explanation of how they function. Transponder keys usually have an aluminum piece that houses the microchip. The chip is shaped similar to the standard key, however it is slightly larger due to the fact that the microchip must be accommodated. The plastic piece is visible when you look closely at the base of the key. The chip transmits an encryption code to the computer in the vehicle's onboard computers. The computer then compares the code with an immobilizer system. If the codes match the engine will begin to run. If not the computers onboard will stop the vehicle from being started, making it impossible for thieves to hot wire the vehicle. While this technology isn't foolproof, it does make it harder for thieves to rob cars. This is also beneficial for those who do not want to accidentally lock their car keys in their vehicle.

Key Fobs A key fob, also known as a remote control is a small device used to open the doors of your car or trunk, and also to start the engine. It also has the panic button which can be used to contact your vehicle's emergency response system in the event of an accident or are in danger. Key fobs connect to your vehicle using radio frequency technology, unlike metal keys that are physically present. A specially-designed receiver on your Toyota's dashboard detects the signals sent by your key fob, and decodes them to open the doors or start the engine. A rolling code is generated every time you press the fob's button making it extremely difficult to clone or replicate these signals. The rolling codes also prevent hacking because the sequence of codes are always changing and cannot be recorded and replayed. The key fobs on the majority of modern Toyotas include an “find-my-car” feature. This will send a message to your vehicle when it is within reach of your key fob. This is useful if you're trying to locate your vehicle in a busy parking lot or street. Many drivers prefer having an additional key fob in the event that the first one breaks or is damaged by accident.

Smart Keys Toyota drivers appreciate the convenience of smart keys. This system takes keyless entry technology a step further, allowing you to open and start your vehicle remotely without the need to insert the key into the ignition slot. Smart keys use RFID, also known as radio-frequency identification to communicate with your Toyota's built-in antennas. When you place the fob within range of your car it sends out a rolling security code that a computer within your vehicle recognizes and verifies. This blocks unauthorized access to your car's trunk and doors. Place the smart keys near the door handle of your Toyota's front passenger or driver. It will send a signal which activates the lights of the puddle and courtesy, if equipped and permit you to access the keyless entry feature. After that, you can use the smart key button to start the engine and leave the parking lot. Certain smart key systems allow you to lock your Toyota by simply touching the door handle. In this scenario, the vehicle will shut your trunk and doors when it detects the smart key. You can then press a button to remotely shut the doors and trunk. Certain models let you push the lock button when your Toyota is in park to turn off the Puddle lights or lights for courtesy, making it more difficult for thieves to steal your vehicle.
