Automotive Locksmith Key Programming Modern automobiles require some kind of key programming . Depending on the model and manufacturer the process could be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM. Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can develop tools or hardware for automotive locksmiths. Transponder Chips Transponder chips are used in a lot of modern cars to stop theft of cars. These are microchips in the form of computers that emit radio signals at a low level. The microchips have an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an enormous success in preventing theft of cars. This technology has also saved car owners a great deal of money since they don't have to replace their vehicles. The principle behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, car thieves used the flat screwdriver to push the ignition switch of your car into “on” mode or even hot-wire it to evade the system. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip. When you insert a transponder key into the ignition, it will transmit a signal that is detected by a hidden antenna around the barrel of the ignition. This antenna is programmed with the 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. Some vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it is essential to ensure that your locksmith in the automotive industry has the right equipment to program your car's keys and fobs correctly. A reputable locksmith for automotive needs to have an instrument for programming keys for multiple vehicles that is compatible with different car manufacturers and models. This is a much 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 one particular brand of vehicle however they are not as frequently used. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reputable firm that has this type of equipment. Key FOBs Key FOBs are programmable transponder chips that allow your vehicle to open doors and start the engine using a push button ignition. It is also possible to press buttons to activate features like door locks, trunk releases or fuel flap controls. Certain fobs come with additional functions that can be controlled by the push of a button like a “smart” key fob that allows you to get your car into tight parking spots, like you would with a Tesla or Genesis GV60. While some replacement keys can be programmed by you using the help of a user manual, you'll often need an automotive locksmith to get a new one programmed if yours stops functioning. A professional locksmith is more equipped to connect your computer to the vehicle to the OBD port under the steering wheel. Today, most key fobs include security features that make it difficult for criminals 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 playing back 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. The locksmith you choose to use will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that make the tools used by auto locksmiths to program their customer's keys. While some of the aftermarket key fobs are advertised as compatible with any vehicle, most automotive locksmiths do not recommend using them because they will likely only work poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle, so that you are certain they'll work properly and are less susceptible to issues like interfering or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs. Vehicle Manufacturers' Programming Tool The automotive industry has made huge advancements in the past few decades. Nowadays, cars are computer-driven. A transponder chip is an important part of this technology. It must be programmed by a locksmith mechanic or dealer to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a movie) and the car will not start if you don't have the right key. Key fobs are somewhat more complicated than a conventional mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob will vary depending on the car model and the key type however they usually cost between $85 and $400. This includes the cost of labor to program the keyfob and any replacement parts. These car key fobs are more complex due to the fact that they use software that interacts with the onboard computer of the car. The software blocks access to unauthorized users by only allowing the key to operate if it has been programmed to the car in question. If you replace your keys, you'll have to program the new key fob to the car to allow it to work. The most popular method to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool permits a locksmith to connect to the OBD port on the vehicle and then enter programming mode. Key programming tools can be a simple handheld device or a more expensive one that can perform a wide range of things that go beyond key programming (like reading and cloning the EEEPROM files in the ECU). While some people may attempt to program their own keys using these tools, it's an activity best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's very easy to make a mistake and alter settings that could cause damage to the vehicle. It's important to keep in mind that a knowledgeable professional can help you avoid these problems. On-Board Programming If your car is old enough, it may still come with a metal key that can be used to open doors and turn the ignition. Modern cars come with transponders that need to be acknowledged and accepted by the computer system in order to start. This adds an extra layer of security that prevents car thieves from starting a stolen car and then driving off with the car. A locksmith who is certified has the tools and software to create a new key that is compatible with your car's security system. First, your locksmith will need to get an uncut key that is compatible with the make and model of your vehicle. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will put your car in a special programming mode, which will allow locksmiths to add a key to the system. The key programmer scanner communicates with the computer of the vehicle to transmit an electronic code. The computer will recognize the code and add it into the list of approved key. In some instances the scanner will be able to erase keys that have been stolen or lost from the system. Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional who has experience with these systems. Locksmiths can program keys quickly by using onboard programming. It can take less than one minute if everything is executed correctly. If the key isn't in the correct situation or the procedure is not adhered to, it could take up to a half hour. There are a variety of key programmer scanners that support different vehicle models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their wide selection of models for vehicles. However, neither will be able to program every single vehicle that exists. Furthermore, these systems are quite expensive. It is recommended to purchase a programmer which will receive regular updates from the manufacturer as new technologies are developed. Your computer's programming software will soon become obsolete if you don't do this.
