Toyota Keys and Transponder Keys Toyotas used to use traditional metal keys for unlocking doors and starting the engine. But times have changed, and many cars now utilize key fobs for the job. It's important to know the different types of key fobs and how they work if you have a Toyota. Transponder Keys Transponder keys are the most common kind of car key. They utilize a microchip to communicate with the vehicle's computer system, and transmit a unique security code. They are designed to resist unauthorized entry, which is why they are so difficult to copy. They are also more expensive than normal keys. Here's a quick explanation of how they function. Typically transponder keys are constructed using a plastic component that houses the microchip. The chip is shaped like the standard key, however it is slightly larger because the microchip must be accommodated. The plastic piece is visible when you examine the base of the key. The chip sends a security code to the computer onboard the vehicle, which will then check the code against an immobilizer system. If the codes are the same then the engine will start. If not the computers onboard will stop the vehicle from beginning, making it almost impossible for thieves to hot wire the car. This technology makes it much more difficult for thieves to steal vehicles, however it's not completely foolproof. It's also beneficial for drivers who don't want to risk accidentally locking their car keys inside their car. However, there are still ways that thieves can try to get around this security feature. Whatever type of key you have it is important to be aware of the possible risks that they pose. If you're worried that someone could steal your car, you should think about changing to a transponder key or purchasing a proximity key. These keys are more expensive and require professional programming. They are also more secure, but are more expensive. They aren't compatible with all cars, so it is best to consult a professional locksmith prior to purchasing one.

Key Fobs A key fob, also referred 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 contains an emergency button that can be used to contact the emergency response system of your vehicle in case of an accident or danger. Key fobs connect to your vehicle using radio frequency technology, unlike physical keys made of metal. A receiver that is mounted on the dashboard of your Toyota receives signals transmitted by the fob that you use to enter your key, and decodes them to unlock doors or start the car. Every time you press the button on your fob you generate a rolling code. This makes it difficult to duplicate these signals. The rolling codes also stop hacking because the sequence of codes are always changing and cannot be recorded and replayed. The majority of newer Toyotas have key fobs that come with an “find my car” feature. It will send a message to your vehicle when it is within range of your key fob.

Smart Keys Keys Toyota drivers love the convenience of a smart key. This system goes one step further and enables you to open and start your car remotely without the need to insert the key into the ignition slot. Smart keys use radio-frequency identification, or RFID, to communicate with the Toyota's built-in antennas. When you place your key fob within range, it sends out an encrypted rolling code that is recognized and verified by the computer in your vehicle. This blocks the unauthorized access to your vehicle's trunk and doors. Place the smart keys near the door handle of your Toyota's front passenger or driver. The smart key will send a signal to activate the puddle or courtesy lights, if equipped, as well as the keyless entry system.

In this case, the vehicle will automatically shut your trunk and doors when it detects the smart key. Then, you can press a button to remotely close the trunk and doors. Some models allow you to push the lock button when your Toyota is in Park to disable the Puddle lights or lights for courtesy, making it more difficult for thieves to rob your vehicle. Certain smart keys also save your driver profile settings such as seat position, climate control and more. Each time you drive, it will automatically adjust to your preferences. This feature is ideal when you have multiple drivers in your Toyota and want to make sure everyone's level of comfort is met. However, it is important to remember that this type of smart key may also be hacked by hackers with advanced technology.
