Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the model and make, the process may be as simple as using an extra key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. It also saves many car owners a significant amount of money as they don't have to buy new their cars.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, thieves would simply push the ignition switch of your car into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system entirely. These kinds of thefts have been dramatically decreased with the introduction of the transponder chip.
When you place the transponder key in the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, power the starter or start it.
Depending on the manufacturer, certain vehicles can only accept a specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming tool that works with different models and car brands. This is a far cheaper option than buying specific tools for each model of vehicle. There are also specialised key programming tools for automobiles that can only be used on specific brands of vehicles, but these are less frequently used. The best locksmiths for automotive have the tools to work on any vehicle. Be sure to choose a reliable company that is equipped with this type of equipment.
Key FOBs
The name implies that key FOBs are home to the transponder chips programmable that allow your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons that you can press to activate features such as trunk release, door locks or fuel flap control. Some fobs have additional functions that can be controlled using the button presses like 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 with the aid of a user's guide but you'll usually need an automotive locksmith to have a new one programmed in case yours stops working. This is because a professional has the right equipment and access to the tools for programming needed to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
Today, most key fobs have security features that make it difficult for hackers to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In many instances you can purchase a replacement key fob from the dealer or from another retailer and then have it programmed by a locksmith for your vehicle to be compatible with your specific vehicle. This is because most of the major US and Asian car manufacturers share their key fob programming protocols with third-party companies who make the tools that locksmiths utilize to programme keys for their customers.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them because 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 like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools
Automotive technology has progressed a lot and modern vehicles require computer technology in order to function. Transponder chips are an essential part of this technology. It must be programmed by a locksmith, mechanic, or dealer to work. Key fobs come with built-in security features that prevent hot-wiring (like in a movie) and the car won't start without the proper key.
These key fobs are more complex than the traditional mechanical key and that's why you'll usually find them in the hands of a reputable professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the type of key however, they generally cost between $85 and $400. This includes labor costs to program the keyfob as well as any replacement parts.
Car key fobs are more complicated due to the fact that they use software that interacts with the computer onboard of the car. The software blocks access by unauthorised persons by only allowing keys that have been programmed for a specific car to function. If you change your keys, you will need to program the new key fob to the car in order for it to function.
The most common way to accomplish this is using the car key programming tool that is compatible with the brand of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle and then enter the programming mode. Key programming tools can either be an inexpensive handheld device or a more expensive one that can do various things beyond just key programming (like reading and cloning EEEPROM files in the ECU).
Some people may attempt to program their keys themselves using these tools. However, this is best left to an expert auto locksmith. It is easy to make mistakes using the software systems if you don't understand the nuances. This can lead to damage. The most important thing to remember is that an experienced professional can help you avoid these issues.
On-Board Programming
If your car is old enough to be considered old-fashioned, you'll have a traditional key made of metal to use to unlock the doors and turn on the ignition. However, modern cars are equipped with a transponder chip that must be recognized by the car's computer system to begin. This is an extra layer of security that stops car thieves from starting a stolen car and then driving off with it. A licensed locksmith will have the necessary tools and software to create a new key that works with your car's security system.
Your locksmith will have to acquire an uncut key that is that is compatible with your car's make and model. Once the key is received the locksmith will connect the scanner for programming to your car's diagnostic port. This will put your car into a special programing mode, which allows locksmiths to add keys to the system.
To accomplish this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will recognize the code and add it to the list of keys approved by. In certain instances the scanner will be able to delete keys that are stolen or lost from the system.
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. This is why it should be left to a professional who has extensive experience working on these types of systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. If everything is done correctly, it can take just one minute. However, if the key isn't placed in the right condition or the procedure isn't followed exactly, it can take up to a half hour.

There are reprogram car key that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their wide selection of models for vehicles. However, neither can be programmed for every vehicle on the market. These devices are also expensive. It is a good idea to buy a programmer that receives regular updates as the manufacturer releases new technologies. If not, your computer will be obsolete in a short time.
