Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer, the process may be as simple as using an additional key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can create tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money as they do not have to buy new vehicles.
The transponder system's basic idea is to make it hard for thieves to get into your car without the right key. In the past, car thieves would simply force your car's ignition switch into the "on" position with the flat screwdriver, or hot-wire the car to bypass the system altogether. Transponder chips have dramatically reduced the number of thefts.
When you insert the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. The antenna is programmed to detect the particular 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.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it's essential to ensure that your locksmith in the automotive industry has the right 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 models and car brands.

The top automotive locksmiths have the appropriate tools to deal with any kind of vehicle, so ensure you choose a reputable firm that has these types of tools.
Key FOBs
The key FOBs are programmable transponder chips that allow your vehicle to open doors and start the engine using a push button ignition. There are also buttons that you can press to activate features like door locks, trunk release 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, such as the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the assistance of a user's manual but you'll usually need an automotive locksmith to have a new one programmed if the one you have isn't working. A professional is better equipped to connect your computer to the vehicle to the OBD port under the steering wheel.
The majority of key fobs today come with security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random sequence generators that generate an entirely new unlock code every 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 most cases you can buy an alternative key fob from the dealer or other retailer and then have it programmed by your automotive locksmith to be compatible with your particular vehicle. This is due to the fact that most of the major US and Asian car manufacturers use key fob programming protocols with third-party companies who create the tools auto locksmiths use to program keys for their customers.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths strongly discourage using them as they are likely to work poorly or even not even work at all. Instead, they suggest purchasing fobs designed specifically for your specific vehicle so that you can be sure they'll function correctly and are less susceptible to issues like interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements for your fobs.

One of the key components of this technology is a transponder chipset that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. These key fobs have built-in security features that stop hot-wiring (like in a movie) and the car won't start without the proper key.
Key fobs are more complicated than a mechanical keys and are the reason they are usually in the hands of a reputable, professional auto locksmith. The cost of a key fob can vary depending on the car model and the type of key however they usually cost between $85 to $400. This includes the labor to program the key fob as well as the costs for any required replacement parts.
To make the process more complicated to make the process more complicated, these key fobs for cars make use of a special software to connect to the car's onboard computer. The software blocks unauthorized access by only allowing 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 programed to the car in order for it to work.
The most common method to do this is by using the car key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter an programming mode. Key programming devices can be a handheld device that is inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
While some may try to program their own keys using these tools, it's something best left to a professional auto locksmith. If you're not aware of all the details of the various software systems, it's easy to accidentally alter settings that could damage the vehicle.

The computer will be able to recognize this code and include it to the list of keys that are authorized. In some 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 by using EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional that has a lot of experience working on these types of systems.

There are a variety of key programmer scanners that support various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they support a broad range of vehicle models. The system cannot program every vehicle.
