Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming with a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian car makers use the same programming protocols as auto tool makers in order to create tools and hardware for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny 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 plugged into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has proven to be extremely successful in preventing theft of cars. This technology has also saved car owners a great deal of money since they don't have to purchase new cars.
The principle behind the transponder system is to make it difficult for thieves to get into your car without a key. In the past, car thieves would force your ignition switch to the "on" position with the flat screwdriver, or hot-wire the car to bypass the system altogether. These kinds of thefts have been dramatically 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 to read the specific frequency of the chip within the key. The onboard computer of the car will recognize the key as being valid and allow fuel flow and power the starter to start the engine.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. This is why it is essential to ensure that your locksmith in the automotive industry is equipped to program your car's key and fobs properly.

In certain instances you can purchase the replacement keyfob at an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle.

The cost of a key fob may vary based on the vehicle model and the type of key however they usually cost between $85 to $400. This includes the cost of labor to program the key fob and the costs for any necessary replacement parts.
