Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then amplified by the specific antenna that is attached to the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip in the key is the correct one for your specific vehicle.
This is what stops from modifying or hot-wiring the vehicle's ignition system to get it started. The chip inside the key also proves that you are the genuine owner of the vehicle. This can reduce car theft.
Transponder keys look like normal keys but have a plastic cap. The chip is contained within the plastic portion of these keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and a siren. This feature is intended to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief could still be able to bypass this system by employing a device designed to take over the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should consider if are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space keys of today can also switch on a heated steering wheel, or open all windows with a single button click. These extra features could make it difficult to locate your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. The signal is encrypted to prevent others from stealing or modifying the signal.
Keyfobs can be programmed in various ways based on the model and make of your vehicle. Certain cars let you do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
When a car is connected with a specific fob, it will only accept signals from that device. As a result, other fobs won't work with the vehicle, even though they have the same appearance. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only work with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by customers without the need of dealers.
