Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on car key programming G28 Car Keys 's make and model, the process could be as simple as onboard programming using a spare key that works or as complicated as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers so that they can develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital 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 immense success in stopping auto theft. This technology has also helped car owners save a huge deal of money as they do not have to purchase new cars.

In the past, car thieves would simply push your car's ignition switch into the "on" position with a flat screwdriver or even hot-wire the car to bypass the system altogether. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it transmits the signal which is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed with the frequency of the chip within the key. The car's computer onboard will recognise that the key is valid and allow fuel to flow, power up the starter, or even start it.
Depending on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. This is why it's crucial to make sure that your locksmith for automotive is equipped to program your vehicle's keys and fobs properly.

This includes labor costs to program the keyfob as well as any replacement parts.
