They have diagnostic software that allows them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips

Transponder chips are likely to be found in cars manufactured within the last 20 years. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

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

This is what stops from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys look like regular metal keys but they have a plastic cap. The chip itself is housed inside the plastic portion of the key and there are different kinds of cuts available on these keys: a regular standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get received by the chip, causing it to send a signal back to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.

If the vehicle does not recognize the transponder signal as being the right one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that blocks the signal.

You can see that the transponder is an excellent option. All car owners should take this into consideration when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today be more than just a way to lock and unlock doors. They can also start the car remotely, make chirping noises to aid in finding cars, or turn on the heated steering wheel. A lot of these additional features may appear convenient however they could make it more difficult to keep the keys to your car.

Key fobs communicate with one other and the car using radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal.

There are a few different ways to program a key fob depending on the vehicle's model and make. Certain models allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.

When you hit the button on a key fob it transmits an encoded code to the car's receiver it is linked to. The receiver compares the information with the permitted signals stored in the key fob, and then opens or locks the car door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.

Once the car has been associated with a particular fob, it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they look the same. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control of it.

The majority of newer dealerships will only work with cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place with the experience to design a replacement fob is in the service department of the dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need of a dealership.
