Professional locksmiths can carry out various types of programming for car keys. Certain types are more complex and require advanced tools. These tools aren't generally available to the public and are used only by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of key programming can be performed by anyone. These are done using the onboard diagnosis port, which can be accessed by a specific tool for key-fob programming. A locksmith can perform this procedure with the help of a guide online and the owner's manual.

Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder inside of it. It's a small plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for your particular car.
This stops the vehicle from being started by hot-wiring or manipulating. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys resemble normal keys but have caps made of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. reprogram car key will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and a siren. This feature is intended to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and determined criminal could still be able to get around this system using a device that can take over the signal.
As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should think about if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car remotely, make chirping noises to aid in finding a car or switch on the heated steering wheel. A lot of these features might seem useful however they could make it harder for you to keep track of your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna in the center of the key. The transmission is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. You can sometimes do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you press a key fob's button it transmits an informational code to the car's receiver that it is linked to. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't able to function.
Once the car is connected to a specific fob, it only accepts signals from the device. As a result, other fobs will not work with the vehicle even if they look the same. This protects the integrity of the computer system in the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by customers without the need of a dealership.
