Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. It's a tiny plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from being started through either hot-wiring or by manipulating. The chip in the car key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip is located inside the plastic part of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to take over the signal.
As you can see there are quite number of advantages to having transponder keys. All car owners should take this into consideration in order to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking lot, today's key fobs can also turn on the heated steering wheel or open all windows with just a single click. A lot of these additional features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip sends an indication to the receiver in the car that it is paired. The receiver then compares the data with the permitted signals stored in the key fob, and then locks or opens the car door. If the data does not match, the car will not be allowed to drive.
After the car has been paired with a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even if they look similar. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control over the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the experience to design a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems, can be programmed without the need for a dealership.
