Automotive Locksmith Key Programming
Modern cars need some type of key programming. Based on the car's make and model, the procedure can be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are found in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio waves. They have an unique serial number that authenticates your keys when 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 an enormous success in preventing car theft. It also saves many car owners a significant amount of money since they don't need to replace their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to start your vehicle without a valid key. In the past car thieves would use a flat screwdriver to force the ignition switch of your vehicle into "on" mode or even hot-wire it to bypass the system. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder keys into the ignition, it will send an electrical signal that is detected by a hidden antenna circling the barrel of the ignition. This antenna is programmed so that it can detect the specific frequency of the chip inside the key. The car's onboard computer will then recognize that the key is valid and allow fuel to flow, turn up the starter, or even start it.
Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. This is why it's essential to ensure that your locksmith in the automotive industry is equipped to program your car's keys and fobs properly.
A good automotive locksmith will possess a multi-vehicle programing device that can be used with different car models and manufacturers. This is a cheaper option than buying individual tools for each brand of vehicle. These are less common, but there are specialised automotive key programmers that can only be used on a specific brand of vehicle. The top automotive locksmiths have the proper equipment to tackle any type of vehicle, so ensure you choose a reputable firm with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and start the engine with the push of a button ignition. It is also possible to press buttons to trigger features such as trunk releases, door locks or control of the fuel flap. Some fobs also have additional functions that can be controlled with the press of a button for example, a "smart" key fob that allows you to bring your car into tight parking spots, like you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the aid of a user's guide however, you'll typically require an automotive locksmith to have a new one programmed if the one you have isn't functioning. A professional locksmith is more equipped to connect the computer of your car via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to clone and replicate the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code every time you press the button on the key fob. This stops attackers from recording and playing back the unlock signal in order to gain access to your car.
In many cases you can purchase an alternative key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that make the tools used by locksmiths who program their customers' keys.
Certain key fobs from the aftermarket may be marketed as being compatible with vehicles of all kinds. However, professional locksmiths strongly discourage using them as they're more likely to perform poorly or not work at all. Instead, they suggest purchasing fobs that are specifically made for your specific vehicle so that you can be certain they'll work properly and are less prone to issues such as interfering or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools

Key fobs can be somewhat more complicated than a standard mechanical key. This is why they are usually in the hands of seasoned professional auto locksmiths. The cost of a key fob may vary depending on the car model and the key type, but they typically run between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
These car key fobs are more complicated due to the fact that they use a software system that works with the computer onboard of the car. The software blocks unauthorized access by only permitting the key to function only if it's programmed to that specific car. If you replace your keys, you'll have to program the new key fob in the car for it to work.
This is accomplished using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a more expensive one that can perform various things that go beyond key programming (like reading and cloning EEEPROM files in the ECU).
Although some people might attempt to program their own keys with these tools, this is something best left to a professional auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's easy to accidentally alter settings that could cause damage to the vehicle.

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional with expertise with these systems.
Locksmiths can program keys quickly with onboard programming. If everything is done properly it can take just one minute. However, if the key isn't in correct situation or the procedure is not strictly followed, it could take as long as a half hour.
