Transponder Chips
If your car is made within the past 20 years, chances are it contains a transponder chip within of it. It's a small plastic piece in the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low level signal. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This is what stops hot-wiring or tampering with the ignition system of the vehicle to start it. The chip in the key also proves that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys look like normal keys but have caps made of plastic. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal will be taken up by the chip, causing it to send a signal back to the car. If the computer in the car detects the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and determined thief might be able bypass this system by using a device that can detect the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all of the windows with just a single push. These additional features could make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are sent by a small antenna in the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends a code to the car's receiver it is linked to. The receiver compared the information with the permitted signals stored on the key fob and then opens or locks the car's door. If the information doesn't match the fob's information, the car won't be allowed to operate.
When a car is connected with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they appear identical. This ensures the security of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills that can only be found in the dealer's service department. Some fobs from the aftermarket, especially those for older models with less sophisticated systems, can be programmed without the need for a dealer.
