Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming with a spare working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create hardware or software for automotive locksmiths.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips have an unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has been an incredible success in preventing auto theft. This technology has also helped car owners save a huge amount of money since they don't have to replace their vehicles.

Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it transmits a signal that is detected by a hidden antenna circling the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will recognize that the key is valid and allow the fuel to flow, then power up the starter or start it.
Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it's essential to ensure that your locksmith in the automotive industry is equipped to program your car's keys and fobs properly.

Today, most key fobs have security features that make it difficult for hackers to clone or replicate the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code each time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances, you can purchase an alternative key fob from the dealer or from another retailer and then have it programmed by your locksmith in your car to fit your particular vehicle.

Key programming tools can either be an inexpensive handheld device or a more expensive one that can perform many things beyond key programming (like reading and cloning the EEEPROM files in the ECU).
Although some people might attempt to program their own keys with these tools, it's an activity best left to an experienced auto locksmith.

You can also program new keys using EEPROM. It is more complex and requires a thorough understanding of electronic systems. It is best to delegate it to a professional with knowledge of these systems.

There are many key programmer scanners that support different car models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their broad range of vehicle models.
