Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming with a spare key that works or as complicated as OBD2 or EEPROM programming.
Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are microchips in the form of computers that emit radio signals at a low level. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has proven to be a huge success in preventing theft of cars. It has also saved many car owners a lot of money because they don't have to buy new their vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, thieves used an ordinary screwdriver to force the ignition switch of your car into "on" mode, or hot-wire it in order to evade the system. Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder key in the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed so that it can read the specific frequency of the chip inside the key. The onboard computer of the car will then recognise the key as being valid and will allow fuel flow, power the starter or start the engine.
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 appropriate equipment to program your car's keys and remotes.

Certain key fobs feature pseudo-random code generators that generate a different unlock code each time you press the button. This prevents attackers from capturing 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 your automotive locksmith to fit your particular vehicle.

This is accomplished by using a programming tool for car keys that is compatible with the brand of your vehicle. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter an programming mode. The key programming device could be an handheld device that is affordable or extravagant and can do more than just program keys (like reading the eeprom file inside the ECU).
