Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the past 20 years. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.

This is what prevents from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key verifies that the owner is the person who owns the vehicle. This can help to reduce car theft.

Transponder keys appear like normal keys but have a plastic cap. The chip is inside the plastic portion of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is received 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 vehicle immobilizer to allow the engine start.

If the car does not 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 siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can take over the signal.

As you can see there are quite few advantages to getting a transponder key. All car owners must take this into consideration if they wish to protect their investment and decrease theft risk.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding a car in a parking lot, today's key fobs can also activate the heated steering wheel or open all windows with a single button press. These extra features can make it difficult to locate your car keys.

Key fobs communicate with each other and with the car through radio frequencies that are transmitted through an antenna in the middle of the key. The communication is encrypted, which helps keep others from stealing and replicating the signal.

There are several ways to program a key fob based on the vehicle's make and model. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or a second fob.

When you hit the button on a key fob it transmits an encoded code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the data does not match the signals, the car will not be allowed to run.

After the car has been paired with a specific fob, it only accepts signals from that device. This means that other fobs will not work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control over it.

Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need for dealers.
