Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder inside of it. It's a small piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is housed inside the plastic portion of the key, and there are a few different types of cuts on these keys: a cut and program car key (a cool way to improve), a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to get around this system employing a device designed to intercept the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all car owners should consider if they are looking to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the car remotely, make chirping noises to aid in finding a car, or turn on the heated steering wheel. These extra features can make it difficult to locate your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob key programming depending on your vehicle's make and model. Certain cars let you do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one.
When you press a key fob's button it transmits an informational code to the car's receiver that it is paired with. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is linked with a particular fob, it will only receive signals from that specific device. Other fobs won't work with the car, even though they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. Some fobs from the aftermarket, especially those for older models with less sophisticated systems can be programmed with out the need for a dealer.
