Automotive Locksmith Key Programming Modern vehicles require some form of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming using a spare key that works or as complicated as EEPROM or OBD2 programming. The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool manufacturers, so they can develop tools or hardware for automotive locksmiths. Transponder Chips Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with a unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a good amount of money by not having to buy new vehicles. The principle of the transponder system is to make it impossible for thieves to get into your car without the right key. In the past, thieves would simply force the ignition switch of your car into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system completely. Transponder chips have dramatically reduced the number of thefts. When you place the transponder key into the ignition the signal is picked up by an antenna hidden around the barrel. This antenna is programmed to read the specific frequency of the chip within 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 according to the manufacturer. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle. A good automotive locksmith will utilize a multi-vehicle programmable tool that can be used with different car models and manufacturers. This is a more cost-effective solution than buying separate tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programming tools that can only be used on a specific type of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reliable company that is equipped with this type of equipment. Key FOBs Key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine using the push of a button ignition. They also have buttons you can push to activate features like door locks, trunk release or control of the fuel flap. Certain fobs can be controlled by pressing buttons. For instance, a "smart key" that allows you summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60. You can program replacement key fobs yourself using the help from the user guide, however you will need to call an automotive locksmith if yours isn't functioning. A professional locksmith is better equipped to connect your computer to the vehicle to the OBD port under the steering wheel. The majority of key fobs are equipped with security features that make it difficult for attackers to replicate and clone the signals that 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 prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle. In many instances, you can purchase a replacement key fob from the dealer or other retailer and have it programmed by your automotive locksmith to fit your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by locksmiths who program their customers' keys. While some of the aftermarket key fobs are advertised as compatible with any vehicle However, the majority of locksmiths in the automotive industry do not recommend using them since they are likely to function poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they will work properly and are less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs. Tools for programming vehicles used by manufacturers The automobile industry has made significant advances in the last couple of decades. Today's cars are computer-driven. One of the key components of this technology is a transponder chip that must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to prevent hot-wiring like in a film. The car will not start if the keys are not correct. These key fobs can be somewhat more complicated than a standard mechanical key. This is why they are placed in the hands of experienced professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the type of key, but they typically run between $85 and $400. This includes the cost of labor to program the key fob as well as the costs for any necessary replacement parts. To complicate the process the car key fobs use a special software system to connect to the car's onboard computer. The software prevents unauthorized access by only allowing the key to operate if it has been programmed to that specific car. This means that if your keys replaced, you'll have to have the new key fob programmed to the car for it to function. 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 lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. Key programming devices can be a handheld device that is cheap or extravagant and can do more than just program keys (like reading the eeprom files in the ECU). Although some people might attempt to program their own keys with these tools, this is something best left to an experienced auto locksmith. If you're not aware of all the aspects of the various software systems, it's possible to make a mistake and alter settings that could potentially damage the vehicle. It's important to remember that an experienced professional will help you avoid these issues. On-Board Programming If your car is older than it could still be equipped with a key made of metal that can be used to open doors and turn off the ignition. Modern cars come with transponder chips that must be recognized by the car's computer system to allow it to start. This is a further security measure to prevent thieves from starting and driving away with a stolen vehicle. A certified locksmith will have the right tools and software to program a new key that will work with your car's security system. The locksmith needs to purchase a blank key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will put your car into a special programming mode that allows the locksmith to add a new key to the system. 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 into the list of keys that are approved. In some instances scanners can erase keys that were stolen or lost. You can also program new keys with the EEPROM. It is more complex and requires an in-depth understanding of how electronic systems function. It's best to leave it to a professional who has expertise with these systems. Onboard programming is the most efficient way for a locksmith to program the new key. It takes as little as an hour if everything is executed correctly. If the key is not in good working order or the procedure isn't followed exactly, the process could take as long as a half hour. There are numerous key programmer scanners that can be used with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they support a broad range of vehicles. However, no system can be programmed for every vehicle on the market. They are also expensive. It's a good idea to purchase a computer that is updated regularly as the manufacturer releases new technologies. Your machine for programming will quickly become obsolete if you don't take this step.
