Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the process could be as simple as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car makers share their programming protocols with auto tool manufacturers in order to create tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit radio signals at a low level. 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 proven to be a huge success in preventing car theft.

In the past car thieves used the flat screwdriver to push the ignition switch of your car to go into "on" mode or even hot-wire it to bypass the system. These kinds of thefts have drastically reduced with the introduction of the transponder chip.
When you insert the transponder key in the ignition the signal is picked up by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognize the key as valid and will allow fuel flow, power the starter or begin the engine.

The majority of key fobs are equipped with security features that make it harder for attackers duplicate and copy the signals they transmit.
