Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the procedure could be as simple as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create software or hardware for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with transponder chips to stop car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a huge amount of money since they don't have to buy new vehicles.
The principle behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, car thieves would force your ignition switch to the "on" position with the flat screwdriver, or use hot wires to disable the system completely. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it will send a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will recognize that the key is valid and allow fuel to flow, power the starter or start it.
Some vehicles only recognize certain type of transponder chip according to the manufacturer. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your car's keys and remotes.
A reputable locksmith for cars should have a multi-vehicle key programming device that can work on many different models and manufacturers of cars. This is a far cheaper option than buying separate tools for each type of vehicle. They are not as common but there are automotive key programmers that are able to only work on a specific brand of vehicle. The top automotive locksmiths have the right tools to deal with any kind of vehicle, so be sure you choose a reputable business with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that allow your vehicle to open doors and begin the engine with the push of a button. It is also possible to press buttons to trigger features such as door locks, trunk releases or fuel flap controls. Some fobs have additional functions that can be controlled with the push of a button, such as a "smart" key fob that allows you to get your car to parking spots that are tight similar to a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help from a user guide, but you will need to call an automotive locksmith in the event that yours has stopped functioning. A professional is better equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
Today, most key fobs come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators which generate a different unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.
In certain instances you can purchase an alternative keyfob from an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that create the tools used by locksmiths who program their customer's keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them as they will likely only work poorly or not at all. Instead, they recommend purchasing fobs specifically designed for your specific vehicle so that you can be certain they'll work properly and are less prone to issues such as interfering or not working. This will save you money in the long run by avoiding costly repairs or replacements of your fobs.

Key fobs are a bit more complicated than a traditional mechanical key and are the reason you'll typically find them in the hands of an expert professional auto locksmith. The cost of a key fob can differ based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes labor costs to program the keyfob and any replacement parts.
To make the process more difficult the car key fobs make use of a special software to communicate with the car's onboard computer. The software blocks access to unauthorized users by only permitting the key to function only if it's programmed for the specific car. This means that if your keys replaced, you'll need to have the new key fob programmed to the car in order for it to function.
This is accomplished by using a tool for programming keys for cars that are compatible with the brand of your 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 can be a simple handheld device or a high-end one that is capable of performing various things that go beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people attempt to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith.

This will put the vehicle into a specific programming mode, which will allow locksmiths to add the key to the system.
The key scanner that is programmed communicates with the computer in the vehicle to transmit the code. car key programming will detect the code and add it to the list of approved key. In some cases the scanner will also erase keys that were stolen or lost.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of how electronic systems work. This is why it should be left to a professional who has a lot of expertise working on these types of systems.

Onboard programming is the fastest way for a locksmith to program an entirely new key. If everything is done properly, it can take just one minute. However, if the key isn't placed in the proper situation or the procedure is not adhered to, it could take up to a half hour.
There are a variety of key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their broad range of models for vehicles. The system cannot program every vehicle. They are also expensive. It's a good idea purchase a programer that is updated regularly when the manufacturer introduces new technologies. In the event that your machine is not updated, it will be obsolete in a short time.
