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 easy as onboard programming using a spare working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automakers share their programming protocol with auto tool manufacturers, so they can design hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal it will 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 buy new vehicles.
The transponder system's basic idea is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, thieves would use the flat screwdriver to push the ignition switch of your vehicle to go into "on" mode or even hot-wire it in order to get around the system. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The car's onboard computer will recognise that the key is genuine and allow fuel to flow, power up the starter or begin it.
Based on the manufacturer, certain vehicles can only accept certain types of transponder chip. This is why it is essential to ensure that your locksmith for automotive has the appropriate equipment to program your car's key and fobs properly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that can work on many different car manufacturers and models. This is a much cheaper option than buying separate tools for each type of vehicle.

The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this type of equipment.
Key FOBs
As the name implies, key FOBs house the transponder chips programmable that enable your vehicle to identify and unlock the doors or start the engine using push-button ignition. They also have buttons that you can press to activate features like trunk release, door locks or control of the fuel flap. Some fobs can be controlled using buttons. For example an "smart key" that lets you call your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual, you'll often require an automotive locksmith to have a new one programmed in case yours stops functioning. This is because a professional locksmith has the equipment that is specialized and access to the programming tools needed to connect your car's computer via the on-board diagnostics (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features that make it harder for attackers replicate and clone the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code each time you press the button on your key fob. This prevents attackers capturing and replaying the unlock signal in order to gain access to your car.
In many cases you can buy an alternative key fob from the dealership or another retailer and have it programmed by your locksmith in your car to be compatible with your specific vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party companies who create the tools used by locksmiths who program their customer's keys.

However, automotive locksmiths strongly discourage using them as they're more likely to perform poorly or not even work at all. Instead, they recommend purchasing fobs specifically designed for your specific vehicle so that you are certain they'll function correctly and are less susceptible to issues such as interfering or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers

The cost of a key fob can differ based on the vehicle model and the key type, but they typically run between $85 and $400. This includes the labor cost to program the keyfob and any 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 blocks unauthorized access by only allowing the key to function only if it's been programmed for the specific car. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car in order to function.
This is done by using a tool for programming car keys that is compatible with the vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter an programming mode. The key programming tool could be a simple handheld device or a fancy one that can perform many things beyond just key programming (like reading and cloning the EEEPROM files in the ECU).
Some people try to program their keys on their own using these tools. However this should be left to a professional auto locksmith. If you're not aware of all the details of the various software systems, it's easy to make a mistake and alter settings that could damage the vehicle.

In certain instances, the scanner will also be able to remove keys that have been stolen or lost from the system.
You can also program new keys with EEPROM. It is more complex and requires a thorough understanding of electronic systems. This is why it's best left to a professional that has extensive experience working with these kinds of systems.
Onboard programming is the most efficient way for a locksmith to program a new key. It can take less than a minute when everything is executed correctly. If the key isn't in the right condition or the procedure isn't being followed exactly, the process can take up to half an hour.
There are many key programmer scanners available that work with various vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicles. There is no system that can program every vehicle. They are also expensive. It's a good idea to purchase a programer that receives regular updates when the manufacturer introduces new technologies. Your computer's programming software check here will soon become obsolete if you do not take this step.
