Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Based on the model and make the process could be as simple as using an additional key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can create software or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are found in many newer cars to stop theft of cars. These are small computer microchips that emit radio signals at a low level. They have a unique serial number that authenticates your key when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has proven to be an enormous success in preventing auto theft. This technology has also helped car owners save a huge deal of money since they don't have to replace their vehicles.

In the past, thieves would use the flat screwdriver to push the ignition switch in your car into "on" mode, or wire it hot to bypass the system. These kinds of thefts have drastically decreased with the introduction of the transponder chip.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip within the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, turn up the starter or begin it.
Depending on the manufacturer certain vehicles can only accept certain types of transponder chip. This is why it is essential to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs properly.

This includes the labor cost to program the keyfob as well as any replacement parts.

The software prevents unauthorized access by permitting the key to function only if it's programmed to that specific car. This means that if your keys replaced, you'll need to have the new key fob programed to the car for it to work.
This is done by using a programming tool for car keys that is compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port in the vehicle and then enter the programming mode.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It is best to delegate it to a professional with experience with these systems.
Onboard programming is the fastest way for a locksmith to program a new key. It can take as little as a minute when everything is executed correctly. If the key is not in the correct condition or the procedure isn't being followed exactly, the process could take as long as a half hour.
