Key Programmers
Modern vehicles require a key-programming process to set up their systems and to start the car. In certain instances the key needs to be programmed by an auto locksmith or a dealer. The key may not function correctly or will not start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to always have two working keys for a modern car and have the replacement key programmed when needed.
A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to copy data from an existing key to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also have a bidirectional user interface to work with an immobilizer system.
There are many different kinds of keyprogrammers on the market, and they come in a variety of shapes and sizes. Some keyprogrammers are cheap, while others can cost thousands of dollar. Some are specifically designed for certain types of vehicles and can offer advanced diagnostics for the car's electronic systems.

They're less expensive than going to a dealership however, they aren't cheap. Make sure you research the seller before purchasing one. Some aren't reliable and can damage your car.
Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder chip inside of it. This is a little plastic piece inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle can then verify that the chip in the key's transponder is the right one for your vehicle.
This stops the vehicle from being started through hot-wiring or manipulating. The chip inside the key also confirms that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of the keys. There are various cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted into 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 to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief could still bypass this system with a specially designed device that blocks the signal.
As you can see, there are quite a few advantages to getting a transponder key. This is something that all car owners should think about if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today 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 turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it harder for you to keep the track of your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are a few different ways to program a key fob, based on the model and make. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver compared this information to the 'allowed' signals on the fob and either opens or locks the door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is linked with a specific fob it will only accept signals from that specific device. This means that other fobs won't work with the vehicle even if they appear similar. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. It is because the only place that has the knowledge to create a replacement fob is in a dealer's service department. Certain aftermarket fobs, typically ones for older models with less advanced systems can be programmed without the need for a dealership.
