Transponder Chips
If your car was built in the last 20 years, chances are it has a transponder inside of it. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.
This prevents the vehicle from starting by either hot-wiring or by tampering. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys resemble normal keys but they have a plastic cap. The chip itself is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is put into an ignition barrel. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer on the car recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined criminal might be able get around this system employing a device designed to take over the signal.
As you can see there are quite number of benefits to having transponder keys. This is something that all car owners should think about if they are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car remotely, emit chirping sounds to help locate cars or turn on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The communication is encrypted, which helps to stop others from stealing and re-transmitting the signal.
There are several ways to program a key fob depending on the model and make. Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob, or an alternative one.
When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle that it is paired. The receiver compared this information with the 'allowed' signals stored on 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 operate.
After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even if they appear identical. This safeguards the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
The majority of car dealers who are newer 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 the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
