Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming with an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian car makers use the same programming protocols as auto tool makers so that they can develop software and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique 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 shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. It has also saved many car owners a lot of money since they don't have to buy new their cars.
The basic concept behind the transponder system is to make it hard for thieves to start your vehicle without a valid key. In the past, thieves would force your ignition switch to the "on" position with a flat screwdriver or even hot-wire the car to bypass the system entirely. These types of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits the signal which is received by a hidden antenna around the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip inside the key. The car's computer onboard will recognize that the key is legitimate and allow fuel to flow, turn the starter or start it.
Some vehicles only recognize a specific type of transponder chip depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.

For instance the "smart key" that lets you call your car into tight parking spaces, like a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual but you'll usually require an auto locksmith to have a new one programmed if the one you have isn't working.

The majority of key fobs come with security features to make it more difficult for criminals to duplicate and copy the signals they transmit. Some key fobs have pseudo-random code generators that generate a different unlock code every time you press the button.
