Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble regular keys made of metal but have a plastic cap. The chip is contained within the plastic part of the key, and there are different types of cuts on the keys: a cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil will emit an electrical signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If reprogram key fob recognizes this signal as being the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and alert you with flashing lights and a siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.
It is evident that the transponder is an excellent option. All car owners should take this into consideration in order to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to help locate cars or turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it harder for you to keep the track of your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located inside the middle of the key. This signal is encrypted to stop others from stealing or stealing the signal.
There are several ways to program a key fob based on your vehicle's model and make. Certain cars let you do it yourself. However, most newer 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 transmits a signal to the receiver inside the car with which it is paired. The receiver compared the information with the permitted signals stored on the key fob and then it opens or closes the car door. If the information doesn't match the signals, the car will not be allowed to run.
When a car is connected with a particular fob, it will only receive signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even if they have the same appearance. This protects the integrity of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the expertise to prepare the replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
