Transponder Chips
If your car is made within the last 20 years, then it contains a transponder chip within of it. This is a little piece of plastic on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This is what stops hot-wiring or tampering with the vehicle's ignition system to start it. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is inside the plastic part of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the computer in the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If car keys programmer isn't able to recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal could still be able to get around this system using a special device to detect the signal.
As you can see there are quite a number of advantages to having transponder keys. Every car owner must take this into consideration if they wish to protect their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking lot, today's key fobs can also activate a heated steering wheel, or roll down all windows with just a single click. A lot of these features might seem useful but they could make it more difficult to keep the track of your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are many ways to program a key fob depending on the vehicle's make and model. You may be able to do it yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob and then opens or locks the car's door. If the data does not match the signals, the car will not be allowed to run.
Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create the replacement fob is the service department of the dealer. Some aftermarket fobs, usually those for older models that have less advanced systems can be programmed with out the need for a dealership.
