Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the car's make and model, the process could be as simple as onboard programming with a spare working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car makers use the same programming protocols as auto tool makers so that they can develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your key when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been a huge success in preventing car theft.

Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder key 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 with the frequency of the chip inside the key. The car's computer onboard will recognize that the key is legitimate and allow the fuel to flow, then power up the starter, or even start it.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. This is why it is crucial to make sure that your locksmith in the automotive industry has the appropriate equipment to program your car's keys and fobs properly.

Automotive technology has progressed a lot and today's vehicles need computer technology to function. One of the most important components of this technology is a transponder chipset that requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to work. Key fobs are fitted with security features that prevent hot-wiring like in a movie. The car will not start without the correct keys.

If you change your keys, you will have to program the new key fob to the car in order for it to work.
This is done by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. Key programming devices can be a handheld device that is affordable or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).

You can also program new keys by using the EEPROM. It is more complex and requires a deep understanding of electronic systems. It is best to delegate it to a professional with expertise with these systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. It takes as little as a minute when everything is executed correctly. However, if the key isn't in correct 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 makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they cover a wide range of vehicles. However, no system can be programmed for every vehicle on the market. In addition, these machines are quite expensive. It's a good idea to purchase a programer that will get regular updates when the manufacturer introduces new technologies.
