Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the process can be as easy as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. These are tiny computer microchips that emit radio signals at a low level. They have a unique serial number that authenticates your key whenever you plug it 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 extremely successful in preventing theft of cars. This technology has also helped car owners save a huge deal of money by not having to purchase new cars.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past, thieves would simply force the ignition switch of your car into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system entirely. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will recognize that the key is legitimate and allow the fuel to flow, then power up the starter, or even begin it.
Depending on the manufacturer, certain vehicles can only accept a specific type of transponder chip. Therefore, it is essential that your automotive locksmith is equipped with the appropriate equipment to program your car's keys and remotes.

The majority of key fobs are equipped with security features to make it difficult for attackers to clone and replicate the signals that they transmit.

Instead, they recommend purchasing fobs that are specifically made for your vehicle, so that you are certain they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing the fobs.

This means that if your keys replaced, you'll need have the new key fob programed to the car to function.
This is accomplished by using a programming tool for keys for cars that are compatible with the vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter an programming mode. Key programming tools can be a simple handheld device or a fancy one that can perform various things beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people attempt to program their keys on their own using these tools. However, this is best left to a professional auto locksmith.

You can also program new keys using EEPROM. It is more complicated and requires a deep understanding of electronic systems. It is best to leave it to a professional with knowledge of these systems.
Locksmiths can program keys quickly by using onboard programming. It can take less than a minute when everything is executed correctly. However, if the key isn't placed in the proper state or the procedure isn't followed exactly, it can take as long as a half hour.
There are numerous key programmer scanners which can work with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they cover a wide range of automobile models. However, neither can be programmed for every vehicle in existence.
