Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Depending on the model and manufacturer the process could be as simple as using an additional key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can create software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are small computer microchips that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proved to be an immense success in stopping auto theft. It has also saved many car owners a significant amount of money since they don't have to replace their cars.

These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will transmit the signal which is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will then recognize that the key is legitimate and allow fuel to flow, power up the starter, or even start it.
Depending on the manufacturer certain vehicles can only accept the specific type of transponder chip. This is why it is essential to ensure that your locksmith for automotive has the appropriate equipment to program your car's keys and fobs correctly.

A professional locksmith is better equipped to connect your computer to the car via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features that make it more difficult for criminals to replicate and clone the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a unique unlock code every time you press the button. This stops attackers from recording and playing back the unlock signal to gain access to your car.
In certain instances you can purchase an alternative keyfob from a dealership or another retailer. The locksmith you choose to use will then program it to work with your vehicle.
