Transponder Chips
If your car was built in the past 20 years, it is likely that it has a transponder inside of it. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a regular standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. automotive locksmith key programming is designed to discourage people from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can take over the signal.
As you can see there are quite few advantages to getting transponder keys. Every car owner should take this into consideration if they wish to protect their investment and reduce theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making chirping sounds to help find a car in a parking space, today's key fobs can also turn on a heated steering wheel or roll down all windows with a single button click. These additional features could make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in different ways based on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press a key fob's button the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver compared this information with the signals that are allowed in the fob and then either opens or locks the door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once the car has been paired with a specific fob, it only accepts signals from the device. As a result, other fobs won't work with the vehicle, even though they appear similar. This protects the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
