Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the model and make, the process may be as simple as using an additional key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. automotive key programming are tiny computer microchips that emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has been a huge success in preventing car theft. This technology has also helped car owners save a good deal of money as they do not have to buy new vehicles.
The transponder system's basic idea is to make it hard for thieves to open the doors of your vehicle without a valid key. In the past car thieves used a flat screwdriver to force the ignition switch of your car into the "on" mode or even wire it hot to bypass the system. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder keys into the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed to detect the specific frequency of the chip within the key. The onboard computer of the car will then recognize the key as being valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it is essential to ensure that your automotive locksmith has the appropriate equipment to program your car's key and fobs correctly.
A good automotive locksmith should have a multi-vehicle key programming tool that can work on many different car manufacturers and models.

Key FOBs

It is also possible to press buttons to activate features like trunk releases, door locks or fuel flap controls. Some fobs have additional functions that can be controlled by the press of a button like a "smart" key fob that allows you to summon 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 to make it difficult for attackers to duplicate and copy the signals that they transmit. Some key fobs have pseudo-random code generators which generate a unique unlock code every time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In many cases you can buy an additional key fob at the dealership or another retailer and have it programmable by your locksmith in your car to be compatible with your specific vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who produce the tools used by locksmiths for programming their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them as they are likely to function poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your specific vehicle so that you are certain they'll function correctly and are less prone to issues like interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing the fobs.

This includes the labor to program the key fob, as well as the costs for any required replacement parts.
The car key fobs are more complex because they utilize an operating system that communicates with the onboard computer of the car. The software blocks unauthorized access by only permitting the key to function only if it's programmed to that specific car. This means that if you need your keys replaced, you'll have to have the new key fob programed to the car in order for it to function.
This is done by using a programing tool for keys for cars that are compatible with the brand of your vehicle. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming device can be an handheld device that is cheap or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).
While some people may attempt to program their own keys with these tools, it's something best left to an experienced auto locksmith.

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional who has experience with these systems.
Onboard programming is the fastest method for locksmiths to program a new key. If everything is done properly it could take just one minute. If the key isn't in the correct condition or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are numerous key programmer scanners which can work with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of models for vehicles. However, neither can program every single vehicle that exists.
