Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with a spare working key or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool makers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. The microchips have an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has proven to be a huge success in preventing theft of cars. This technology has also saved car owners a great amount of money as they do not have to purchase new cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, thieves would simply force the ignition switch of your car into the "on" position using an ordinary screwdriver or use hot wires to disable the system entirely. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder keys into the ignition, it will transmit a signal that is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip inside the key. The computer onboard of the car will recognize the key as being valid and allow fuel flow, power the starter or start the engine.
Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs correctly.
A reliable locksmith for cars will utilize a multi-vehicle programmable device that can be used on a variety of different models and brands of cars. This is a far cheaper option than buying specific tools for each model of vehicle. They are not as common but there are automotive key programming tools that can only work on a specific model of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reliable company that is equipped with this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and begin the engine with the push of a button ignition. There are also buttons that you can press to trigger features like door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled by the press of a button like a "smart" key fob that lets you bring your car into tight parking spots, like you would with the Genesis GV60 or Tesla. Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the assistance of an instruction manual, however you'll need to contact an automotive locksmith if the one you have isn't working.

Today, most key fobs have security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the key fob's button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy a replacement keyfob from a dealership or another retailer. Your locksmith at your auto will then program it to work with your car. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who create the tools used by locksmiths who program their customer's keys.

However, professional locksmiths strongly discourage using them as they're more likely to perform poorly or even not at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing the fobs.

Key fobs with embedded security features that will prevent hot-wiring (like in a film) and the car won't start if it doesn't have the proper key.

The cost of a key fob may differ based on the vehicle model and the key type however they usually cost between $85 to $400. This includes the labor to program the key fob, as well as the costs for any necessary replacement parts.

You can also program new keys by using EEPROM. It is more complicated and requires a thorough understanding of how electronic systems function. This is why it's best left to a professional who has years of experience working with these kinds of systems.
Locksmiths can program keys quickly with onboard programming. If everything is done correctly it can take as little as one minute. If the key isn't in good working order or the procedure isn't followed exactly, the process could take up to half an hour.
There are numerous key programmer scanners that support various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they support a broad range of automobile models. However, neither can be programmed for every vehicle in existence. These machines are also quite expensive. It's best to purchase an instrument that receives regular updates from the manufacturer as new technologies are introduced. Otherwise, your programming machine will soon become obsolete.
