Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with a spare key that works or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio waves. The microchips have a unique serial number which authenticates your key when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be a huge success in preventing car theft. This technology has also helped car owners save a huge amount of money as they do not have to buy new vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to start your car without a key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car into the "on" mode, or hot-wire it to get around the system. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it will send an electrical signal that is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then recognise that the key is genuine and allow the fuel to flow, then power up the starter, or even begin it.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. This is why it's important to ensure that your locksmith in the automotive industry has the appropriate equipment to program your car's key and fobs correctly.

For instance an "smart key" that lets you call your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the assistance of a user's manual, you'll often need an automotive locksmith to get a brand new one programmed in case yours stops working. A professional locksmith is better equipped to connect your computer to the vehicle to the OBD port located under the steering wheel.
The majority of key fobs are equipped with security features that make it harder for attackers duplicate and copy the signals that they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most cases you can purchase a replacement key fob from the dealer or other retailer and have it programmable by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who produce the tools used by auto locksmiths to program their customers' keys.
While some aftermarket key fobs are marketed as being compatible with any vehicle However, the majority of locksmiths in the automotive industry don't recommend using them because they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they function properly and are less susceptible to issues like interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements of your fobs.

Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires an in-depth understanding of how electronic systems operate. This is why it's best left to a professional that has a lot of expertise working on these types of systems.
