Transponder Chips Transponder chips can be found in vehicles manufactured within the last 20 years. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car. When activated by an electro-magnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle. This is the reason why doing hot-wiring or altering the vehicle's ignition system to turn it on. The chip in the car key confirms that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle. Regular transponder keys are designed like regular metal keys with a plastic top. The chip itself is housed within the plastic part of the key and there are different cuts that can be found on the keys: a standard 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 sends out an electrical signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer inside the car is able to recognize the signal as being correct, it will disable vehicle immobilizer so that the engine can start. If the vehicle doesn't recognize the transponder signal as being the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to tamper with the vehicle, but it's not a 100% security measure. A skilled and committed thief could still be able to escape this security system by employing a device designed to take over the signal. As you can see, there are quite a few advantages to getting a transponder key. This is something that all car owners should consider if they want to safeguard their investment and minimize the chance of theft. Key Fobs Key fobs today can be more than just a way to lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding the car or turn on the heated steering wheel. These additional features could make it difficult to find your car keys. Key fobs communicate with one other and the car using radio frequencies which are transmitted through an antenna that is located in the center of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal. Keyfobs can be programmed in a variety of ways depending on the model and make of your vehicle. Certain cars let you do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one. When you press the button on your key fob, the microchip inside transmits an encoded code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's doors. If the information doesn't match, the car will not be allowed to run. When a car is connected with a specific fob it will only accept signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle. Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the experience to design a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed with out the need for a dealer.
