The days of relying on traditional metal keys to unlock and start your car are long gone. Technology has made great progress. With transponder and smart keys, accessing your car has become safer and more convenient.
However, some vehicle owners can’t decipher between these two types of keys and that is the reason we’d dive and explore them in this article.
If you are curious to know more about transponders and smart keys, you’d learn a lot below.
In the early 1990s, transponder technology and advanced car key systems with high security were introduced to stop the increasing problem of car theft.
The transponder key, or chip key, is made for cars and has an electronic authorization device. We use this key to start our cars, motorcycles, and various other vehicles.
The transponder device is capable of storing data, and car manufacturers utilize it to hold a unique "password" specific to each vehicle. We’ve got your back if need transponder key replacement service.
When you put a transponder key in the ignition, the antenna ring sends a radio frequency code to the chip inside the key. Using the antenna ring, the chip sends its code back to be verified by the car's ECM (Engine Control Module).
If the car recognizes the code, the immobilizer is deactivated, and the engine is unlocked, enabling the vehicle to start. Keep in mind that a locksmith can assist you with key fob programming and other services.
A smart key is an advanced version of a traditional car key, including technology to help you manage your car's locks, start the engine, and perform other functions seamlessly.
In modern smart keys, communication takes place between the key and the car's antennas, enabling the exchange of signals that are interpreted by the vehicle's electronic computer. The computer then sends specific commands to carry out the desired functions, ensuring a smooth and efficient operation.
The smart key doesn't need the driver to remove the key fob from their pocket. Instead, it connects to one of the car's antennas, allowing the control unit to send a radio pulse that unlocks the vehicle or activates the ignition as long as the key is inside the car.
Moreover, modern vehicles can adjust various settings when the smart key remote is present, such as the driver's seat position, steering wheel adjustment, and even stereo presets.
