Transponder Chips
If your car is made within the last 20 years, then it has a transponder chip inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. This signal then gets absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the right one for your particular car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the car key confirms that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys but have caps made of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil will emit signals when the transponder is put into ignition barrel. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer, allowing 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 will warn you with flashing lights and a siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not an absolute security measure. A skilled and committed thief may still be able to get around this system using a device that can take over the signal.
You can see that a transponder is a great option. This is something that all car owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding the car, or turn on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
There are many ways to program a key fob, based on your vehicle's model and make. Some cars allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the car that it is paired. The receiver compares this information with the 'allowed' signals in the fob and then either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to run.
Once the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even if they look similar. programming car key protects the integrity of the computer system in 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 sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems can be programmed without the need for a dealer.
