Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based 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 OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers in order to create hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates your key 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 proved to be an immense success in stopping auto theft. This technology has also helped car owners save a huge deal of money since they don't have to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, car thieves used an ordinary screwdriver to force the ignition switch in your car into "on" mode, or hot-wire it to evade the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert the transponder key in the ignition the signal is picked up by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's computer onboard will detect that the key is legitimate and allow fuel to flow, turn the starter or start it.
Based on the manufacturer, certain vehicles can only recognize certain types of transponder chip. It is therefore essential that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.

This is a cheaper option than purchasing separate tools for each brand of vehicle.

The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so make sure you choose a reputable business with these kinds of tools.
Key FOBs

There are also buttons that you can press to trigger features like door locks, trunk release or control of the fuel flap. Some fobs can be controlled by pressing buttons. For example, a "smart key" that lets you call your car to parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from the user guide, however you will need to call an automotive locksmith if yours has stopped working.

The majority of key fobs are equipped with security features that make it difficult for attackers to clone and replicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase a replacement keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because most of the major US and Asian car manufacturers use key fob programming protocols with third-party companies who make the tools that auto locksmiths employ to programme keys for their customers.
Although some key fobs from the aftermarket are advertised as compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them as they're likely to work poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you can be sure they'll function properly and be less prone to issues such as interference or incompatibility. This will save money over time by avoiding costly repairs or replacements of your fobs.

You can also program new keys using the EEPROM. It is more complicated and requires a deep understanding of how electronic systems operate. It's best to leave it to a professional with expertise with these systems.
Onboard programming is the fastest way for a locksmith to program a new key. If everything is done correctly it could take as little as one minute. If the key isn't in the proper situation or the procedure is not adhered to, it could take as long as a half hour.
There are a variety of key programmer scanners that can be used with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they support a broad range of vehicles. However, no system can be programmed for every vehicle in existence. These machines are also quite expensive. It is a good idea to purchase a computer that receives regular updates when the manufacturer introduces new technologies.
