Automotive Locksmith Key Programming Modern cars need some type of key programming. Depending on the vehicle's make and model, the procedure can be as easy as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming. The majority of US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can develop tools or hardware for locksmiths in the automotive industry. Transponder Chips Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio signals at a low level. The microchips are equipped with a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down 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 deal of money as they do not have to purchase new cars. The transponder system's basic idea is to make it impossible for thieves to open the doors of 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 make use of hot-wires to bypass the system altogether. Transponder chips have drastically reduced the number of thefts. When you insert the transponder keys in the ignition the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and will allow fuel flow and power the starter to begin the engine. Some vehicles only recognize certain type of transponder chip, depending on the manufacturer. This is why it is important to ensure that your locksmith for automotive has the appropriate equipment to program your vehicle's keys and fobs correctly. A reputable locksmith for automotive needs to have a multi-vehicle key programming device that works with different models and manufacturers of cars. This is a cheaper option than purchasing specific tools for each type of vehicle. They are not as common, but there are specialised automotive key programmers that can only work on a particular model 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 As the name suggests, key FOBs house the transponder chips that can be programmed to allow your vehicle to identify and unlock the doors or start the engine using push-button ignition. They also have buttons that you can push to activate features such as trunk release, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled using the push of a button like the “smart” key fob that lets you summon your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60. You can program spare key fobs by yourself with the help of the user guide, however you will need to call an automotive locksmith if yours isn't functioning. A professional locksmith is more equipped to connect your computer to the vehicle via the OBD port located under the steering wheel. Today, most key fobs have security features that make it difficult for attackers 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 prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle. In many cases you can buy an additional key fob at the dealer or other retailer and have it programmable by your automotive locksmith to fit your specific vehicle. This is due to the fact that most of the major US and Asian car manufacturers use key fob programming protocols with third-party firms that make the tools that locksmiths for auto employ to programme keys for their customers. Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, professional locksmiths strongly discourage using them as they're likely to function poorly or not at all. They suggest buying fobs 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 in the end by avoiding costly repairs or replacing your fobs. Tools for programming vehicles used by manufacturers The automotive industry has advanced considerably and modern vehicles require computer technology to function. One key element of this technology is a transponder chip that needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to prevent hot-wiring, as in a movie. The car will not start if the keys are not correct. Key fobs are a little more complex than the mechanical keys and are the reason you'll usually find them in the hands of a reputable, professional auto locksmith. The cost of the car key fob is depending on the model and type of key, but is typically between $85 to $400. This includes the cost of labor to program the keyfob and any replacement parts. To make the process more difficult, these car key fobs make use of a special software to work with the car's onboard computer. The software blocks unauthorized access by only allowing the key to function if it has been programmed to that specific car. If you change your keys, you'll need to program the new key fob to the car for it to function. The most common way to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows locksmiths to connect to the OBD port on the vehicle and then enter programming mode. The key programming device could be a handheld device that's cheap or sophisticated and capable of doing more than just program keys (like reading the eeprom file inside the ECU). Although some people might attempt to program their own keys with these tools, it's something best left to a professional auto locksmith. If you're not aware of all the details of the various software systems, it's very easy to accidentally change settings that could cause damage to the vehicle. The most important thing to remember is that a professional with experience can assist you in avoiding these problems. On-Board programming If your car is of a certain age that you'll have a traditional metal key to open the doors and turn over the ignition. Modern cars come with a transponder that must be acknowledged and accepted by the computer system in order to start. This is an extra layer of security that stops car thieves from starting a stolen car and driving away with the car. A licensed locksmith will have the necessary tools and software to create a key that will work with your car's security system. Your locksmith will need to acquire an uncut key that is that is compatible with your car's model and make. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put the car into a special programing mode, which allows locksmiths to add the key to the system. The key scanner is programmed to communicate with the computer in the car to send an electronic code. The computer will recognize the code and add it to the list of approved keys. In certain instances the scanner will be able to delete keys that are stolen or lost from the system. You can also program new keys using EEPROM. It is more complicated and requires a deep understanding of electronic systems. It is best to leave it to a professional with expertise with these systems. Onboard programming is the fastest way for a locksmith to program the new key. It can take as little as one minute if everything is executed correctly. However, if the key isn't in the right situation or the procedure isn't adhered to, it could take up to an hour. There are a variety of key programmer scanners available that support different car models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their wide selection of vehicle models. No system can program every vehicle. These machines are also quite expensive. It's a good idea purchase a computer that receives regular updates when the manufacturer introduces new technologies. If not, your computer will be obsolete in a short time.
