Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the vehicle's make and model, the procedure can be as easy as programming onboard using an extra working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio signals. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has been an immense success in stopping auto theft. It also saves many car owners a lot of money as they don't have to replace their vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to start your car without a key. In the past, car thieves would simply push the ignition switch of your car into the "on" position using a flat screwdriver or even make use of hot-wires to bypass the system completely. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it will send a signal that is received by a hidden antenna that is positioned around 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 recognize that the key is legitimate and allow the fuel to flow, then power the starter or begin it.
Depending on the manufacturer some vehicles will only recognise certain types of transponder chip. It is therefore important that your locksmith in the automotive industry is equipped with the right equipment to program your car's keys and remotes.

The best automotive locksmiths will have the proper tools to work on any type of vehicle, so make sure you choose a reputable business with these kinds of tools.
Key FOBs

There are also buttons that you can push to activate features such as door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled by the press of a button, such as the "smart" key fob that lets you bring your car to parking spots that are tight, like you would with the Genesis GV60 or Tesla.

The majority of key fobs come with security features that make it difficult for attackers to clone and replicate the signals they transmit. They include pseudo-random generators that generate a fresh unlock code every time you press the button on your key fob. This is to prevent attackers from capturing and replaying the unlock signal in order to gain access to your car.
In many cases you can buy an additional key fob at the dealer or from another retailer and have it programmable by a locksmith for your vehicle to be compatible with your particular vehicle. This is due to the fact that most of the major US and Asian car manufacturers share their key fob programming protocols with third-party firms that produce the tools locksmiths utilize to program keys for their customers.
Certain key fobs from the aftermarket may be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths strongly discourage using them as they are likely to work poorly or even not at all. Instead, they recommend purchasing fobs specifically designed for your vehicle so that you are certain they'll function properly and be less prone to issues like interfering or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.
