Automotive Locksmith Key Programming Most modern-day cars require some kind of key programming. Based on the model and make the procedure could be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM. The majority of US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop hardware or software for automotive locksmiths. Transponder Chips Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. The microchips have an unique serial number that authenticates your key whenever 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 enormous success in preventing car theft. It also saves many car owners a significant amount of money as they don't have to buy new their vehicles. The basic idea behind the transponder system is to make it impossible for thieves to start your car without a key. In the past, thieves used the flat screwdriver to push the ignition switch of your car into the “on” mode, or hot-wire it to bypass the system. These kinds of thefts have been dramatically decreased with the introduction of the transponder chip. When you insert the transponder key in the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, power up the starter, or even begin it. Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes. A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that is compatible with different car manufacturers and models. This is a far cheaper option than buying specific tools for each model of vehicle. These are less common however, there are specialist automotive key programming tools that can only be used on a specific brand of vehicle. The most reliable automotive locksmiths will have the right tools to work on any type of vehicle, so make sure you find a reputable company with these kinds of tools. Key FOBs Key FOBs are programmable transponder chips that allow your vehicle to unlock doors and start the engine using a push button ignition. They also have buttons that you can press to trigger features such as trunk release, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled with the push of a button for example, a “smart” key fob that allows you to summon your car into tight parking spots as you would with the Genesis GV60, Tesla or Genesis GV60. You can program replacement key fobs yourself with the help of an instruction manual, however you'll need to contact an automotive locksmith if yours isn't functioning. This is because a professional locksmith has the equipment that is specialized and access to the programming tools required to connect your car's computer through the OBD (OBD) port that is located under the steering wheel. The majority of key fobs today 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 fresh unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle. In some cases, you can buy a replacement keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who produce the tools used by auto locksmiths to program their customers' keys. While some aftermarket key fobs are advertised as compatible with any vehicle However, the majority of locksmiths in the automotive industry don't recommend using them because they are likely to function poorly or not at all. Instead, they suggest buying fobs specifically designed for your specific vehicle so that you can be certain they'll function properly and be less prone to issues such as interfering or not working. This will save money over time by avoiding costly repairs or replacements for your fobs. Tool for Programming Vehicle Manufacturers' The automobile industry has made significant strides in the last few decades. Today's cars are computer-driven. One key element of this technology is a transponder chip which requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order 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 can be a little more complex than a conventional mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob may vary depending on the car model and the type of key, but they typically run between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts. To complicate the process to make the process more complicated, these key fobs for cars use a special software system to connect to the car's onboard computer. The software blocks access to unauthorized users by only permitting the key to function if it has been programmed for the specific car. This means that if you need your keys replaced, you'll have to have the new key fob programmed to the car in order to function. This is accomplished using a programing tool for keys for cars that are compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle and then enter programming mode. The key programming device can be an handheld device that is inexpensive or one that is fancy and can do more than just program keys (like reading the eeprom file inside the ECU). Although some people might attempt to program their own keys using these tools, this is something best left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's possible to accidentally change settings that could potentially damage the vehicle. The most important thing to remember is that a professional with experience can help you avoid these issues. On-Board Programming If your car isn't as old that it has a key, it might still come with a key made of steel that you can use to open doors and turn the ignition. Modern cars come with transponders that need to be recognized and accepted by the computer system in order to start. This is an extra layer of protection that can stop car thieves from stealing a car and then driving off with it. A locksmith who is certified will have the necessary tools and software to create a new key that works with the security system in your car. First, your locksmith needs to purchase an uncut key that is compatible with the model and make of your car. Once the key is in your possession the locksmith will connect the programming scanner to the diagnostic port of your car. This will place the car into a special programming mode that will allow the locksmith to add a new key into the system. To do this, the key programming scanner will communicate with the car's computer system to transmit an exact code. The computer will be able to recognize this code and add it into the list of approved key. In some cases, a scanner can also remove keys that have been stolen or lost. You can also program new keys by using EEPROM. It is more complex and requires a deep understanding of how electronic systems function. This is why it should be left to a professional that has years of experience working with these kinds of systems. Onboard programming is the fastest way for a locksmith to program the new key. When everything is done correctly, it can take just one minute. If the key is not in the correct condition or the procedure isn't followed exactly, the process can be as long as half an hour. There are numerous key programmer scanners which can work with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their wide selection of models for vehicles. However, neither will be able to program every single vehicle that exists. Additionally, these devices cost a lot. It is recommended to purchase one that will receive regular updates from the manufacturer whenever new technologies are introduced. Your computer's programming software will soon become obsolete if you don't take this step.
