Transponder Chips
If your car was built in the last 20 years, it is likely that it contains a transponder chip within of it. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the right one for your particular car key reprogram.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is located inside the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car recognizes the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an absolute security measure. A skilled and skilled criminal can still get around this system by using a specific device that blocks the signal.
You can see that a transponder is a great option. Every car owner should consider this when they want 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 sound chirps to help locate the car in a parking lot, today's key fobs can also switch on the heated steering wheel or roll down all of the windows with just a single click. Many of these extra features might seem useful but they could make it difficult for you to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna in the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button it transmits an informational code to the car's receiver that it is linked to. The receiver compared this information to the signals that are allowed in the fob and then either opens or locks the door. If the information doesn't match the signals, the car will not be allowed to run.
Once the car is connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look identical. This helps to protect the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. Some aftermarket fobs, usually those from older models that have less advanced systems, can be programmed without the need for a dealership.
