Transponder Chips Transponder chips are likely be found in cars manufactured in the last 20 years. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own. When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your vehicle. This stops the vehicle from being started through either hot-wiring or by tampering. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle. Transponder keys appear like regular keys made of metal but have caps made of plastic. The chip is contained inside the plastic portion of the key and there are different types of cuts on these keys: a regular cut laser cut (also called a sidewinder key) or Ford Tibbe key. When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start. If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and siren. This function is designed to discourage people from tampering with the vehicle. However it's not an absolute security measure. A skilled and skilled criminal could still evade this system by using a specific device that intercepts the signal. As you can see there are quite number of advantages to having transponder keys. This is something that all car owners should consider if they are looking to safeguard their investment and decrease the risk of theft.

A lot of these features may seem convenient however they could make it harder for you to keep the keys to your car. Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. The signal is encrypted to prevent others from stealing or modifying the signal. You can program a keyfob in a variety of ways depending on the make and model of your car. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or an additional one. When you press a key fob's button the microchip inside sends a code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's door. If the information does not match the signals, the car will not be allowed to run. After the car has been connected to a specific fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even though they have the same appearance. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it. The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place that has the experience to design an appropriate replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models with less advanced systems, can be programmed without the need for a dealership.
