Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is taken up by an antenna that is attached to the barrel of ignition. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This can help to reduce car theft.
Transponder keys look like regular keys made of metal but they have a plastic cap. The chip is inside the plastic portion of these keys. There are several different cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the car does not recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an absolute security measure. A determined and skilled thief could still bypass this system by using a specific device that intercepts the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all vehicle owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking space Key fobs today can also activate the heated steering wheel or open all windows with a single push. A lot of these features might seem useful, but they can also make it harder for you to keep the keys to your car.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted via an antenna in the center of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Certain models allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order 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 inside the vehicle with which it is paired. The receiver then compares this information to the 'allowed' signals stored 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 operate.
Once the car has been paired with a specific fob, it will only accept signals from the device. This means that other fobs won't work with the vehicle even though they have the same appearance. This ensures the security of the computer system in the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare an appropriate replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
