Toyotas used to use traditional keys made of metal for unlocking doors and starting the engine. But times have changed, and now many vehicles utilize key fobs for the job.
If you own a Toyota that requires a key fob, then it's important to understand the various types of key fobs that are available and how they work.
Transponder Keys
Transponder keys are the most popular kind of car key. They make use of a microchip that allows them to connect to the vehicle's computer system and transmit a unique security code. They are designed to prevent unauthorised entry, which is also why they are so difficult to duplicate. They're also more expensive than standard keys. Here's a quick overview of how they function.
Transponder keys typically have a plastic piece to house the microchip. The chip looks like a regular key, but it's a bit larger than a conventional key due to having to house the microchip. The plastic piece is fixed to the base of the key and is evident when you look at it carefully. The chip transmits an encryption code to the computer in the vehicle's onboard computers. The computer will then check the code against an immobilizer system. If the codes are the identical then the engine will start. If the codes do not match, the computer onboard will block the vehicle from starting, making it almost impossible for thieves to hot wire the car.
This technology makes it more difficult for thieves to steal vehicles, however it's not foolproof. It's also helpful for drivers who want to avoid accidentally locking their car keys inside their own vehicle. However, there are still ways that thieves can try to get around this security feature.

You'll also have to provide the locksmith details about your vehicle, including model and make. This will help them identify the correct key for your vehicle and then program it accordingly.
Key Fobs
A key fob, also known as a remote control is a small device used to open your car's doors, trunk and start the engine. It also has an emergency button that can be used to call your vehicle's emergency response system when you have an accident or are in danger. Unlike physical metal keys that are made of metal, key fobs make use of radio frequency technology to communicate with your vehicle.

Every time you press the button on your fob, you generate a rolling code. This makes it extremely difficult to copy or duplicate the signals. The rolling codes also stop hacking because the sequence of codes are always changing and cannot be recorded and replayed.
The key fobs on the majority of newer Toyotas have a "find-my-car" feature. The fob will notify your vehicle when you get within range of the fob, which will allow you to locate your car even when you have lost it. This is useful if you're trying to locate your car in a busy street or parking lot.

Smart Keys
Toyota customers love the convenience of a smart key. This system takes keyless technology a step further, allowing you to start and unlock your car remotely.
Smart keys use radio-frequency identification, or RFID to communicate with your Toyota's built-in antennas. When you put the fob within range of your car it sends out a rolling security code that a computer inside your vehicle detects and validates. This prevents unauthorized users from gaining access to your vehicle's trunk and doors without permission.
Place the smart key close to the door handle of your Toyota's front driver or passenger. It will send a signal which activates the puddle or courtesy lights when they are on and allows you to access keyless entry options. After that, you can utilize the smart key button to start the engine and then leave the parking area.
Some smart key systems allow you to lock your Toyota by touching the door handle. In this case the vehicle will detect the smart key and then automatically manage your trunk and doors. You can then press another button to remotely close the doors and trunk. Some models even let you press the lock button when your Toyota is in park to turn off the courtesy lights or puddle making it more difficult for thieves to steal your car.
