Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a huge amount of money by not having to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to get into your car without a key. In the past, car thieves would simply force the ignition switch of your car into the "on" position with an ordinary screwdriver or make use of hot-wires to bypass the system completely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it transmits an electrical signal that is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will recognize that the key is valid and allow fuel to flow, turn the starter or begin it.
Some vehicles only recognize specific type of transponder chip depending on the manufacturer. This is why it's important to ensure that your automotive locksmith is equipped to program your car's key and fobs properly.
A good automotive locksmith will have a multi-vehicle programming device that can be used on a variety of different models and brands of cars.

There are also specially-designed key programming tools for automobiles that can only be used on specific brands of vehicles however, they are less common. The top automotive locksmiths have the appropriate tools to deal with any kind of vehicle, so be sure you find a reputable company with these kinds of tools.
Key FOBs
The name implies that key FOBs house the programmable transponder chips that enable your car to recognize and unlock the doors or start the engine using push-button ignition. You can also use the buttons to trigger features such as door locks, trunk releases or fuel flap controls. Certain fobs can be controlled with the press of buttons. For example an "smart key" that lets you call your car to tight parking spaces, like a Tesla or Genesis GV60.

The majority of key fobs come with security features that make it harder for attackers duplicate and copy the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase an alternative keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of the major US and Asian automobile manufacturers have key fob programming protocols with third-party firms that produce the tools locksmiths for auto use to program keys for their customers.
While some aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them as they are likely to function poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your vehicle, so that you can be certain they'll function correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.

The cost of a car key fob varies dependent on the type and model of key, but it is usually between $85 to $400. This includes labor costs to program the keyfob and any replacement parts.
Car key fobs are more intricate due to the fact that they use a software system that works with the onboard computer of the car. The software blocks unauthorized access by allowing the key to function only if it's programmed to the car in question. This means that if your keys replaced, you'll need to have the new key fob programmed to the car for it to work.
This is accomplished by using a programming tool for keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. Key programming tools can be a handheld device that is inexpensive device or a high-end one that can perform many things beyond just key programming (like reading and cloning the Eeprom files within the ECU).

You can also program new keys with EEPROM. It is check here more complicated and requires a thorough understanding of electronic systems. It is best to leave it to a professional who has knowledge of these systems.

There are numerous key programmer scanners that can be used with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide range of vehicle models. There is no system that can program every vehicle.
