Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with a spare working key or as complex as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number which authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been a huge success in preventing theft of cars. It has also saved many car owners a lot of money because they don't need to replace their vehicles.

Transponder chips have drastically reduced these types of thefts.
When you insert the transponder keys in the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, turn the starter or start it.
Based on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. This is why it's important to ensure that your locksmith in the automotive industry is equipped to program your car's keys and fobs correctly.
A reliable locksmith for cars will have a multi-vehicle programming device which can be used on many different automobile models and manufacturers.

For example the "smart key" that lets you call your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed with the assistance of a user's manual, you'll often require an automotive locksmith to have a new one programmed if the one you have isn't functioning. A professional locksmith is better equipped to connect your computer to the vehicle via the OBD port on the steering wheel.
The majority of key fobs come with security features to make it harder for attackers clone and replicate the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code every time you press the button.

These key fobs have built-in security features that stop hot-wiring (like in a movie) and the car won't start if it doesn't have the right key.
Key fobs are a little more complex than a conventional mechanical key. This is why they are handled by experienced professional auto locksmiths. The cost of the car key fob can vary according to the model and type of key, but it is generally between $85 to $400. This includes the labor to program the key fob as well as the costs for any necessary replacement parts.
To complicate the process to make the process more complicated, these key fobs for cars make use of a special software to work with the car's onboard computer. The software blocks access by unauthorised persons by only permitting keys that have been programmed specifically for a particular car to function. This means that if your keys replaced, you'll have to have the new key fob programed to the car in order for it to work.
The most popular method to do this is by using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. Key programming devices can be an handheld device that is inexpensive or one that is sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).

The key scanner is programmed to communicate with the computer in the car to send an electronic code. The computer will be able to recognize the code and add it to the list of keys that are approved. In some instances the scanner will be able to erase keys that are stolen or lost from the system.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional who has a lot of expertise working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program a new key. If everything is done correctly it could take as little as one minute. If the key isn't in the correct condition or the procedure isn't being followed exactly, the process could take as long as a half hour.
There are many key programmer scanners on the market that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they support a broad range of vehicle models. However, neither will be able to program every single vehicle that exists. These machines are also quite expensive.
