Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. This is a little plastic thing in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys look like regular metal keys but have a plastic cap. The chip is contained in the plastic portion of the key, and there are different types of cuts on these keys: a cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be taken up by the chip, causing it to send a signal back to the car. If the computer onboard the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine, and will alert you with flashing lights and siren. This is designed to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal might be able bypass this system by employing a device designed to intercept the signal.
It is evident that the transponder is an excellent option. This is something that all car owners should consider if are looking to safeguard their investment and minimize the chance of theft.
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 switch on the heated steering wheel or roll down all windows with a single push. These extra features could make it difficult to locate your car keys.
Key fobs communicate with each other and the car using radio frequencies which are transmitted by an antenna that is located in the middle of the key. This communication is encrypted, which helps to stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and make of your car. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip sends signals to the receiver in the vehicle that it is paired. The receiver then compares this information to the signals that are allowed inside the fob, and either opens or closes the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car is associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even if they look like. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only deal with cars with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
