Transponder Chips

If your car is made within the past 20 years, chances are it has a transponder chip inside of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

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

This is what stops from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key verifies that the owner is the one who owns the vehicle. This can help to reduce car theft.

Transponder keys resemble normal keys but they have a plastic cap. The chip is housed inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.

If the car 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 discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still be able to bypass this system by using a special device to intercept the signal.

As you can see there are quite a few advantages to getting transponder keys. Every car owner should consider this when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

These extra features can make it difficult for you to locate your car keys reprogramming keys.

Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.

There are many ways to program a key fob, based on the vehicle's make and model. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.

When you press the button on a key fob, the microchip sends a signal to the receiver in the car that it is paired. The receiver then compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to run.

When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. In turn, other fobs won't be able to work with the vehicle even though they look the same. This protects the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that is only available in the dealer service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by consumers without the need for a dealership.
