Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's a tiny plastic piece on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal then gets amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the key confirms that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble regular metal keys, but with a plastic cap. The chip itself is housed in the plastic portion of the key, and there are different kinds of cuts available on these keys: a 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 sends out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the car's computer detects this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and an alarm. This feature is intended to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still evade this system by using a specific device that blocks the signal.
As you can see there are quite a few advantages to getting transponder keys. 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 lot, today's key fobs can also switch on the heated steering wheel or open all windows with a single button press. These extra features can make it difficult for you to locate your car keys.
Key fobs use radio frequencies to communicate with one another and the car. These frequencies are transmitted by a small antenna within the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are a few different ways to program a key fob, based on your vehicle's make and model. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is linked. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.
Once the car has been connected to a specific fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available 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 of a dealership.
