Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can design hardware or software for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips in order to prevent theft. These are small computer microchips that emit low-level radio signals. They have an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has been a huge success in preventing car theft. This technology has also saved car owners a great amount of money since they don't have to buy new vehicles.
The principle behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, car thieves used the flat screwdriver to push the ignition switch in your car to go into "on" mode, or hot-wire it in order to bypass the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you place the transponder key in the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip in the key. The car's onboard computer will then recognise that the key is legitimate and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it's important to ensure that your locksmith in the automotive industry has the appropriate equipment to program your car's keys and fobs correctly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that works with different models and manufacturers of cars. This is a far more cost-effective approach than purchasing separate tools for each type of vehicle. There are also specially-designed key programming devices for automotive that are only suitable for one particular brand of vehicle however, they are less popular. The best locksmiths for automotive are equipped to work on any vehicle. Make sure you select a reliable company that is equipped with this type of equipment.
Key FOBs
As the name implies, key FOBs contain transponder chips that can be programmed to allow your car to recognize and unlock the doors, or start the engine using push-button ignition. You can also press buttons to activate features such as trunk releases, door locks or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For example, a "smart key" that allows you summon your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the aid of a user's guide however, you'll typically require an automotive locksmith to get a brand new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect your computer to the vehicle to the OBD port under the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a new unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy a replacement key fob from the dealership or another retailer and then have it programmed by a locksmith for your vehicle to work with your specific vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with the third-party firms who create the tools used by auto locksmiths to program their customer's keys.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles, most automotive locksmiths do not recommend using them since they will likely only work poorly or not at all. Instead, they suggest buying fobs that are specifically made for your vehicle so that you can be sure they'll work properly and are less susceptible to issues such as interfering or not working. This will save you money over the long term by avoiding expensive repairs or replacing the fobs.
Tool for programming the vehicle manufacturers

One of the most important components of this technology is a transponder chipset that must be programmed into the vehicle by an auto locksmith or dealer/mechanic order to function. Key fobs are fitted with security features to prevent hot-wiring, as in a movie. The car won't start if the keys are not correct.
Key fobs are a little more complex than a traditional mechanical key. This is why they're usually in the hands of seasoned, professional auto locksmiths. The cost of a key fob can vary based on the vehicle model and the type of key, 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 make use of a special software to communicate with the car's onboard computer. The software prevents unauthorized access by only allowing the key to function only if it's been programmed to that specific car. This means that if your keys replaced, you'll need have the new key fob programmed to the car for it to work.
This is accomplished using a tool for programming keys for cars that are compatible with the brand of your vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. Key programming tools can be a handheld device that is inexpensive device or a fancy one that can perform many things that go beyond key programming (like reading and cloning the Eeprom files within the ECU).
Some people may attempt to program their keys on their own using these tools. However, this is best left to an expert auto locksmith.

You can also program new keys using EEPROM. It is more complex and requires a thorough understanding of how electronic systems function. This is why it should be left to a professional who has a lot of experience working with these kinds of systems.
Onboard programming is the fastest way for a locksmith to program an entirely new key. If everything is done correctly it can take as little as one minute. If the key is not in the correct condition or the procedure isn't followed precisely, the procedure could take as long as a half hour.
There are numerous key programmer scanners on the market that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their broad range of models for vehicles. No system can program every vehicle. These machines are also quite expensive. It is recommended to purchase a programmer which will receive regular updates from the manufacturer as new technologies are introduced.
