Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer, the process may be as simple as using an extra key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. The microchips are equipped with a unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car isn't able to recognize the signal, it will shut down 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 by not having to purchase new cars.
The basic concept behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, thieves would simply push your car's ignition switch into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system entirely. Transponder chips have drastically decreased the likelihood of theft.
When you insert the transponder keys into the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will recognize that the key is legitimate and allow fuel to flow, turn up the starter, or even begin it.
Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. This is why it is essential to ensure that your automotive locksmith has the right equipment to program your car's keys and fobs correctly.

For example the "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself using the help of an instruction manual, however you will need to call an automotive locksmith if yours isn't functioning.

The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique 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 many cases you can buy an additional key fob at the dealership or another retailer and then have it programmed by your locksmith in your car to work with your specific vehicle. This is because most of the major US and Asian car manufacturers have key fob programming protocols with third-party companies who produce the tools locksmiths employ to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with any vehicle However, the majority of locksmiths in the automotive industry here don't recommend using them since they will likely only work poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your specific vehicle so that you are certain they'll function properly and be less susceptible to issues like interfering or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing the fobs.

The cost of a key fob may vary depending on the car model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the key fob, as well as the cost of any needed replacement parts.
To make the process more difficult the car key fobs use a special software system to work with the car's onboard computer. The software prevents unauthorized access by only permitting the key to function only if it's been programmed for the specific car. If you change your keys, you'll have to program the new key fob in the car in order for it to work.
The most common method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter the programming mode. The key programming device could be an handheld device that is affordable or fancy and can do more than just program keys (like reading the eeprom file inside the ECU).
While some people may attempt to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. If you're not familiar with the details of the various software systems, it's possible to make a mistake and alter settings that could damage the vehicle.

EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of how electronic systems operate. This is why it should be left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the quickest method for locksmiths to program the new key. It can take as little as one minute if everything is completed correctly. If the key isn't placed in the correct condition or the procedure is not strictly followed, it could take up to a half hour.
There are a variety of key programmer scanners that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide selection of models for vehicles. There is no system that can program every vehicle. These devices are also expensive. It is recommended to purchase one that will receive regular updates from the manufacturer whenever new technologies are released.
