Transponder Chips

If your car was manufactured in the past 20 years, then it has a transponder chip inside of it. It's a tiny piece of plastic in the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip in the key is the right one for the car you have.

This stops the vehicle from starting by either hot-wiring or by altering the key. The chip in the car key confirms that the owner is the one who owns the vehicle. This helps to prevent car theft.

Transponder keys resemble normal keys but they have caps made of plastic. The chip is located inside the plastic part of these keys. There are several different cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.

A circuit inside the induction coil emits an electrical signal when the transponder is put into the ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as being the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will warn you with flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal might be able bypass this system by using a special device to intercept the signal.

As you can see, there are quite a number of benefits to having transponder keys. Every car owner must take this into consideration in order to safeguard their investment and minimize the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all windows with a single press. These extra features could make it difficult to find your car keys.

Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.

There are several ways to program a key fob depending on the model and make. You can sometimes do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.

When you press a key fob's button the microchip inside sends an informational code to the car's receiver it is paired with. The receiver then compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the information does not match, the car will not be allowed to drive.

After the car has been associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear similar. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. Some aftermarket fobs, usually those for older models with less sophisticated systems, can be programmed without the need for a dealer.
