Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the past 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys appear like regular metal keys, but with caps made of plastic. The chip itself is housed in the plastic portion of the key, and there are different cuts that can be found on the keys: a standard cut laser cut (also called 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 is received by the chip which then transmits a signal to the vehicle. If the computer in the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and an alarm. This feature is intended to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.
You can see that the transponder is an excellent option. All car owners should take this into consideration in order to safeguard their investment and decrease theft risk.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the car remotely, make chirping noises to aid in finding cars, or switch on the heated steering wheel. A lot of these features might seem useful but they could make it difficult for you to keep the track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted via an antenna in the center of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. It is possible to do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob, the microchip transmits an indication to the receiver inside the car with which it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the information doesn't match the fob's information, the car won't be allowed to operate.
Once the car is associated with a particular fob, it can only receive signals from the device. In turn, other fobs will not work with the vehicle even though they have the same appearance. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially those from older models with less advanced systems, can be programmed without the need for a dealer.
