Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming with a spare key that works or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car makers use the same programming protocols as auto tool manufacturers in order to create hardware and software for automotive locksmiths to use.
Transponder Chips
Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips which emit radio signals of low-level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proved to be an enormous success in preventing auto theft. This technology has also helped car owners save a good amount of money as they do not have to purchase new cars.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car into the "on" mode or even hot-wire it in order to get around the system. Transponder chips have drastically reduced these types of thefts.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will then detect that the key is legitimate and allow fuel to flow, turn up the starter or start it.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs correctly.

Most key fobs today come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.

This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party companies who create the tools used by locksmiths for programming their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them as they are likely to function poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.

If you change your keys, you'll need to program the new key fob into the car for it to work.

There are many key programmer scanners on the market that support different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they can be used with a variety of vehicles. However, no system can program every vehicle in existence.
