Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the process can be as simple as onboard programming with an extra working key or as complex as OBD2 or EEPROM programming.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, which means they can design software or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are in a variety of newer vehicles to prevent car theft. These are tiny computer microchips that emit low-level radio signals. The microchips are equipped with a unique serial number which authenticates your key whenever you plug it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been a huge success in preventing car theft. This technology has also saved car owners a great deal of money by not having to replace their vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to open the doors of your car without the right key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car into the "on" mode or even hot-wire it to bypass the system. Transponder chips have dramatically reduced these types of thefts.
When you insert the transponder key in the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the appropriate equipment to program your car's keys and remotes.
A good automotive locksmith will utilize a multi-vehicle programmable device that can be used on a variety of different automobile models and manufacturers. This is a more cost-effective alternative to purchasing separate tools for each brand of vehicle. These aren't as popular however, there are specialist automotive key programming tools that can only be used on a specific brand of vehicle. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs

There are also buttons that you can press to activate features like door locks, trunk release or fuel flap control. Certain fobs come with additional functions that can be controlled using the button presses, such as the "smart" key fob that lets you bring your car into tight parking spots, like you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from the user guide, however you'll need to contact an automotive locksmith in the event that yours isn't working.

The majority of key fobs are equipped with security features to make it harder for attackers clone and replicate the signals they transmit. Certain key fobs feature pseudo-random code generators which generate a different unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some instances you can purchase an alternative keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party companies who produce the tools used by locksmiths who program their customer's keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle However, the majority of locksmiths in the automotive industry do not recommend using them because they are likely to function poorly or not at all. Instead, they suggest buying fobs designed specifically for your vehicle so that you can be certain they'll function properly and be less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing your fobs.

The cost of a key fob may differ based on the vehicle model and the key type, but they typically run 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, these car key fobs utilize a specific software system to connect to the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed specifically for a particular car to function. This means that if your keys replaced, you'll need to have the new key fob programmed to the car 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 permits a locksmith to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming tool could either be an inexpensive handheld device or a fancy one that can do a wide range of things beyond key programming (like reading and cloning the EEEPROM files in the ECU).

You can also program new keys using EEPROM. It is more complex and requires a deep understanding of how electronic systems operate. This is why it should be left to a professional that has extensive experience working on these types of systems.
