Transponder Chips Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car. The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for your specific vehicle. This prevents the vehicle from starting by either hot-wiring or by tampering. The chip in the car key verifies that the owner is the one who owns the vehicle. This can help to reduce the possibility of theft from your vehicle. Transponder keys resemble normal keys but have caps made of plastic. The chip itself is housed within the plastic part of the key and there are different kinds of cuts available on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key. A circuit inside the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer, allowing the engine to start. If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and an alarm. This feature is intended to deter people from trying to alter the vehicle, but it's not a 100% security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal. As you can see there are quite number of benefits to having a transponder key. This is something that all car owners should consider if they want to protect their investment and decrease the chance of theft. Key Fobs Key fobs today can be more than just a way to lock and unlock doors.

Many of these extra features may seem convenient however they could make it difficult for you to keep track of your car keys. Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted by a small antenna located in the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal. There are several ways to program a key fob based on your vehicle's make and model. Certain models allow you to do it 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 an additional one. When you press a key fob's button, the microchip inside transmits an encoded code to the car's radio that it is linked to. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate. Once the car is paired with a specific fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle, even though they appear similar. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control of the vehicle. The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in the service department of a dealer. Some aftermarket fobs, usually those from older models that have less advanced systems, can be programmed without the need for a dealer.
