Transponder Chips

If your car is made in the last 20 years, it is likely that it has a transponder inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for your specific vehicle.

This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.

Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are several different cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and an alarm. This feature is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A determined and skilled thief could still bypass this system using a special device that blocks the signal.

It is evident that a transponder is a great option. This is something that all car owners should think about if they want to safeguard their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking lot keys of today can also turn on the heated steering wheel or roll down all of the windows with a single click. Many of these extra features may seem convenient but they could make it more difficult to keep the keys to your car.

Key fobs communicate with each other and the car using radio frequencies that are transmitted by a small antenna located in the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.

You can program a keyfob in various ways based on the model and make of your vehicle. Certain cars let you do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a car key a new key fob, or an alternative one.

When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is linked. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then opens or locks the car's door. If the information doesn't match the signals, the car will not be allowed to run.

Once the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs won't work with the vehicle even if they look the same. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of 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 expertise to prepare an appropriate replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
