Transponder Chips
If your car was built in the past 20 years, chances are it contains a transponder chip within of it. It's a small plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your vehicle.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is located inside the plastic part of these keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. 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 bypass this system using a special device that detects the signal.
As you can see there are quite a few advantages to getting a transponder key. All car owners should consider this if they wish to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding the car or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted through an antenna in the center of the key. This communication is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in a variety of ways depending on the model and make of your car. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip transmits signals to the receiver in the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the information does not match, the car will not be allowed to run.
Once the car is linked with a specific fob it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place with the knowledge to create an appropriate replacement fob is a dealer's service department. However, car key programing that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
