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 simple as onboard programming using an extra working key or as complex as OBD2 or EEPROM programming.

Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number which authenticates your key when 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 been an incredible success in preventing auto theft.

Transponder chips have drastically reduced the number of thefts.
When you insert the transponder key in the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will then detect that the key is valid and allow the fuel to flow, then power the starter or start it.

The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific car to function. If you replace your keys, you will need to program the new key fob into the car to allow it to work.
This is done by using a programming tool for keys for cars that are compatible with your vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode.

Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires a deep understanding of how electronic systems work. It is best to leave it to a professional who has experience with these systems.
Locksmiths can program a key quickly with onboard programming. It can take less than a minute when everything is completed correctly. If the key is not in the right condition or the procedure isn't followed exactly, the process could take as long as a half hour.

Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their broad range of models for vehicles. However, neither can program every vehicle on the market.
