Transponder Chips
If your car is made within the last 20 years, then it contains a transponder chip within of it. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip in the key is the correct one for your specific vehicle.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are various cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit within the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the computer in the car is able to recognize the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and skilled criminal could still bypass this system using a special device that blocks the signal.
As you can see there are quite a number of advantages to having a transponder key. All car owners should consider this in order to safeguard their investment and reduce the risk of theft.
Key Fobs

A lot of these additional features might seem useful however they could make it difficult for you to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located inside the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on your vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button it transmits an encoded code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then locks or opens the car's door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even if they look similar. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in a dealer's service department. Certain aftermarket fobs, typically those from older models with less sophisticated systems can be programmed with out the need for a dealership.
