Transponder Chips

If your car was manufactured within the past 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of the car key that has 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. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your vehicle.

This stops the vehicle from being started by hot-wiring or manipulating. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car key reprogramming near me recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still bypass this system using a special device that blocks the signal.

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

Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are sent through a small antenna located in the middle of the key. This communication is encrypted, which helps keep others from stealing and retransmitting the signal.

Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Certain cars let you do it yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or an additional one.

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information does not match the fob key programmer (these details)'s information, the car won't be allowed to drive.

Once the car is connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, even though they look similar. This helps to protect the integrity of the vehicle'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 a car with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
