Transponder Chips
Transponder chips are likely be found in cars manufactured within the last 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This is what stops hot-wiring or tampering with the vehicle's ignition system to start it. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys 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 the keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will then get received by the chip and cause it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and a siren. This is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still bypass this system by using a specific device that intercepts the signal.
You can see that a transponder is a great option. All car owners should consider this in order to safeguard their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking space Key fobs today can also switch on a heated steering wheel or open all windows with a single push. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted via an antenna that is located in the center of the key. The communication is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in various ways based on the model and make of your car. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compares the information with the permitted signals stored in the key fob and then it opens or closes the car's door. If the information does not match the fob's information, the car won't be allowed to run.
Once the car is associated with a particular fob, it can only receive signals from the device. This means that other fobs won't be able to work with the vehicle even though they have the same appearance. This helps to protect the integrity of the car's computer system and prevent unauthorised key fobs from taking control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
