Modern cars require some type of key programming. Depending on the model and manufacturer, the process may be as simple as using an additional key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian car makers use the same programming protocols as auto tool makers to allow them to develop software and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are small computer microchips that emit low-level radio signals. The microchips have an unique serial number that authenticates your key whenever you connect it to the ignition barrel.

These types of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit the signal which is detected by a hidden antenna around the barrel of the ignition. This antenna is programmed so that it can detect the particular 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 begin it.
Based on the manufacturer, certain vehicles can only accept certain types of transponder chip. Therefore, it is essential that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.

You can also program new keys by using EEPROM. It is more complicated and requires a thorough understanding of how electronic systems function. It's best to leave it to a professional with experience with these systems.
Locksmiths can program a key quickly using onboard programming. It takes as little as one minute if everything is completed correctly. However, if the key isn't in the correct situation or the procedure is not adhered to, it could take up to a half hour.
There are a variety of key programmer scanners that can be used with different makes and models of vehicles.
