4 Dirty Little Tips About The Toyota Key Industry Toyota Keys and Transponder Keys

There was a time when Toyotas utilized traditional metal keys to open doors and start the engine. The times have changed and many vehicles are now equipped with key fobs.

It is important to understand the different kinds of key fobs that are available and how they function in the event that you own a Toyota.

Transponder Keys

Transponder keys are the most popular type of car keys. They make use of a chip that allows them to connect with the computer system of the vehicle and transmit a unique code. They're designed to ward off unauthorized access, which is the reason they are so difficult to duplicate. They also cost more than normal keys. Here's a quick overview of how they function.

Typically transponder keys are constructed with a plastic piece that houses the microchip. The chip is designed like a standard key, but slightly larger as the microchip needs to be incorporated. The plastic piece can be seen when you take a close look at the key's base. The chip transmits a security code to computer in the vehicle's onboard computers. The computer will then check the code against an immobilizer system. If the codes match, same then the engine will start. If the codes don't match, the computer onboard will prevent the vehicle beginning, making it nearly impossible for thieves to hot wire the vehicle.

Key Fobs

A key fob, also known as a remote control, is a small device used to open the doors of your vehicle and trunk and to start the engine. It also contains an emergency button that can be used to connect with the emergency response system of your vehicle in the event of an accident or a danger. Contrary to metal keys that are physical, key fobs use radio frequency technology to communicate with your vehicle.

A receiver that is mounted on the dashboard of your Toyota picks up signals sent by the key fob, and decodes them in order to unlock doors and start the vehicle. When you press the button on your fob a rolling code is generated. This makes it difficult to duplicate or copy the signals. The rolling codes prevent hacking since the sequences of code are always changing and can't be recorded or replayed.
