These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with a computer.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the small plastic piece in the head of the car key that has 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. This signal is then taken up by an antenna attached to the ignition barrel. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This stops the vehicle from being started through hot-wiring or tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car keys cut and programmed near me.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed within the plastic part of the key, and there are different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer onboard the car recognizes the signal as valid it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief could still be able to bypass this system by employing a device designed to intercept the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all car owners should think about if they want to safeguard their investment and minimize the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding the car or switch on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted via an antenna that is located in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are many ways to program a key fob depending on the vehicle's make and model. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the vehicle with which it is linked. The receiver compares the information with the permitted signals stored on the key fob and then opens or locks the car's door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.
Once the car is paired with a specific fob, it only accepts signals from the device. As a result, other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only work with vehicles 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 knowledge that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by customers without the need of a dealership.
