Toyota Keys and Transponder Keys Toyotas used to use traditional metal keys to unlock doors and start the engine. But times have changed, and many cars now utilize key fobs for the job. It's essential to be aware of the different kinds of key fobs that are available and how they work when you have a Toyota. Transponder Keys Transponder keys are the most common type of car keys. They utilize a chip to communicate with the computer system of the vehicle and transmit an unique code. They're also designed to block unauthorized access, which is the reason they are so difficult to duplicate. They are also more expensive than standard keys. Here's a quick explanation of how they work. 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 due to the fact that the microchip must be accommodated. The plastic piece is fixed to the key's base and is visible when looking at it closely. The chip sends an immobilizer code to the onboard computer of the vehicle. If the codes are compatible the engine will begin to run. If the codes don't match, the computer onboard will stop the vehicle from starting, making it almost impossible for thieves to wire the vehicle. This technology makes it harder for thieves to steal vehicles, however it's not completely foolproof. This is also beneficial for drivers who aren't keen on locking the keys to their car.

Key Fobs A key fob is a small device that opens your car doors, trunk and also starts the engine.

A receiver 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 and start the vehicle. Every time you press the button on your fob, a rolling code is generated. This makes it difficult to duplicate these signals. The rolling codes also stop hacking since the sequence of codes are always changing and cannot be recorded or replayed. Most newer Toyotas have key fobs that come with an “find my car” feature.
