Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers so that they can develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio waves. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a good deal of money since they don't have to purchase new cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past car thieves used the flat screwdriver to push the ignition switch of your car into the "on" mode or even wire it hot to get around the system. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder key into the ignition, it will send a signal that is picked up by a hidden antenna around the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow the fuel to flow, then power up the starter or start it.
Some vehicles only recognize specific type of transponder chip, depending on the manufacturer. This is why it's important to ensure that your locksmith for automotive has the right equipment to program your car's keys and fobs properly.

Some fobs also have additional functions that can be controlled by the button presses for example, the "smart" key fob that allows you to bring your car into parking spaces that are difficult to access similar to 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 that they transmit. Certain key fobs feature pseudo-random code generators that generate a different unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy an additional key fob at the dealer or other retailer and have it programmed by a locksmith for your vehicle to work with your specific vehicle. This is due to the fact that most of the major US and Asian car makers share their key fob programming protocols with third-party companies who create the tools locksmiths use to program keys for their customers.
Some aftermarket key fobs may be advertised as compatible with any vehicle. However, automotive locksmiths advise against using them since they are likely to work poorly or even not even work at all. They suggest buying fobs designed specifically for your vehicle so that they function properly and are less susceptible to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.

The cost of the car key fob can vary dependent on the model and type of key, but it is usually between $85 and $400. This includes labor costs to program the keyfob and any replacement parts.

The software blocks access to unauthorized users by permitting the key to function if it has been programmed to that specific car. If you replace your keys, you'll have to program the new key fob to the car in order for it to function.
The most common way to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. The key programming tool could be a simple handheld device or a fancy one that is capable of performing various things that go beyond key programming (like reading and cloning Eeprom files within the ECU).

In some instances, the scanner will also be able to delete keys that are stolen or lost from the system.
You can also program new keys with EEPROM. It is more complex and requires a deep understanding of electronic systems. It is best to delegate it to a professional with knowledge of these systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. If everything is done properly it can take just one minute. If the key isn't in the correct condition or the procedure isn't being followed exactly, the process could be as long as half an hour.
There are numerous key programmer scanners that work with various car models and makes.
