Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using an extra working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool manufacturers, so they can design software or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are found in many newer cars to stop theft of cars. These are microchips in the form of computers that emit low-level radio signals. The microchips have a unique serial number which authenticates your key when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge amount of money as they do not have to purchase new cars.
The basic concept behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, thieves used a flat screwdriver to force the ignition switch in your car into the "on" mode or even hot-wire it to bypass the system. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will send a 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 specific frequency of the chip within the key. The car's onboard computer will then recognize that the key is valid and allow fuel to flow, power up the starter or begin it.
Depending on the manufacturer, certain vehicles can only accept the specific type of transponder chip. It is therefore essential that your locksmith in the automotive industry is equipped with the appropriate equipment to program your car's keys and remotes.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different models and manufacturers of cars. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. These aren't as popular but there are automotive key programmers that are able to only work on a particular brand of vehicle. The most reliable automotive locksmiths will have the appropriate tools to work on any type of vehicle, so make sure you choose a reputable business that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and begin the engine with a push button ignition. You can also press buttons to trigger features such as door locks, trunk releases or fuel flap controls. Certain fobs come with additional functions that can be controlled with the button presses like the "smart" key fob that lets you bring your car into tight parking spots as you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the assistance of the user guide, however you'll need to contact an automotive locksmith if the one you have has stopped functioning. A professional locksmith is more equipped to connect your computer to the car via the OBD port located under the steering wheel.
Today, most key fobs have security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the button on your key fob. This is to prevent attackers from capturing and playing back the unlock signal in order to gain access to your vehicle.
In most cases, you can purchase a replacement key fob from the dealership or another retailer and then have it programmed by your automotive locksmith to be compatible with your specific vehicle. This is due to the fact that most of the major US and Asian automobile manufacturers share their key fob programming protocols with third-party companies that make the tools that locksmiths for auto use to programme keys for their customers.
Although some key fobs from the aftermarket are advertised as compatible with any vehicle However, the majority of locksmiths in the automotive industry don't recommend using them since they will likely only work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they function properly and are less susceptible to issues such as interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements for your fobs.
Toolkits for Programming Vehicles of Manufacturers
Automotive technologies have progressed a lot and modern vehicles require computer technology to function. One key element of this technology is a transponder chip that requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. These key fobs have built-in security features that prevent hot-wiring (like in a movie) and the car won't start if it doesn't have the proper key.
These key fobs are a bit more complex than your mechanical keys, which is why they are usually in the hands of an expert professional auto locksmith. The cost of a key fob can vary depending on the car model and the key type however, they generally cost between $85 and $400. This includes the labor required to program the key fob, as well as the costs for any necessary replacement parts.
The car key fobs are more complex because they utilize a software system that works with the onboard computer of the car. The software blocks access by unauthorised persons by only allowing keys that have been programmed for a specific vehicle to function. This means that if your keys replaced, you'll need to have the new key fob programed to the car for it to function.
The most common way to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. The key programming device can be a handheld device that is affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys with these tools, this is an activity best left to an experienced auto locksmith. It is easy to make mistakes using the software systems if you don't understand the nuances. This could result in damage. It's crucial to remember that a knowledgeable professional can help you avoid these issues.
On-Board Programming
If your vehicle is old enough that you'll have a traditional key made of metal that you can use to open the doors and turn on the ignition.

The key scanner is programmed to communicate with the computer of the vehicle to transmit an electronic code. The computer will be able to recognize this code and include it to the list of keys that are authorized. In some cases, the scanner will also be able to erase keys that have been stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has expertise with these systems.
Onboard programming is the fastest way for a locksmith to program the new key. If everything is done properly it could take just one minute. However, if the key isn't in proper state or the procedure is not strictly followed, it could take up to an hour.
There are many key programmer scanners on the market that work with various vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their wide range of models for vehicles. The system cannot program every vehicle. They are also expensive. It is recommended to purchase one that will receive regular updates from the manufacturer as new technologies are developed. Your programming machine will quickly become obsolete if you do not take this step.
