Why No One Cares About Automotive Locksmith Key Programming
Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian car manufacturers have programming protocols that they share 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 what are called transponder chips in order to prevent theft. These are small computer microchips that emit radio signals at a low level. 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 does not recognize the signal and the engine is shut down. This technology has proven to be a huge success in preventing car theft. It has also saved many car owners a lot of money since they don't have to replace their vehicles.
The principle of the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would simply push your car's ignition switch into the "on" position with a flat screwdriver or even make use of hot-wires to bypass the system entirely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's onboard computer will recognize that the key is legitimate and allow fuel to flow, turn up the starter or begin it.
Some vehicles only recognize a specific type of transponder chip according to the manufacturer. It is therefore important that your locksmith in the automotive industry is equipped with the right equipment to program your keys and remotes for your vehicle.

Some key fobs have pseudo-random code generators which generate a new unlock code each time you press the button.
