Automotive Locksmith Key Programming Most modern-day cars require some form of key programming. Based on the model and make the procedure could be as simple as using an extra key to program the onboard computer or as complicated as EEPROM or OBD2 programming. Most US and Asian car makers have programming protocols that they share with auto tool manufacturers in order to create software and hardware for automotive locksmiths to use. Transponder Chips The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a good deal of money by not having to purchase new cars. 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 used the flat screwdriver to push the ignition switch in your car into "on" mode, or hot-wire it in order to get around the system. These kinds of thefts have drastically reduced with the introduction of the transponder chip. When you insert the transponder keys into the ignition the signal is picked up by an antenna hidden around the barrel. This 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 legitimate and allow fuel to flow, power up the starter or start it. Depending on the manufacturer, certain vehicles can only recognize certain types of transponder chip. This is why it's important to ensure that your automotive locksmith is equipped to program your car's key and fobs correctly. A good automotive locksmith will utilize a multi-vehicle programmable device that can be used on a variety of different automobile models and manufacturers. This is a more cost-effective option than purchasing separate tools for each brand of vehicle. These aren't as popular however, there are specialist automotive key programmers that are able to only work on a particular type of vehicle. The top automotive locksmiths have the appropriate equipment to tackle any type of vehicle, so make sure you find a reputable company with these kinds of tools. Key FOBs The key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and start the engine with a push button ignition. You can also press buttons to trigger features such as door locks, trunk releases or control of the fuel flap. Some fobs can be controlled by pressing buttons. For instance an "smart key" that allows you summon your car into tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60. While some replacement key fobs can be programmed with the assistance of a user's manual but you'll usually require an auto locksmith to get a new one programmed if the one you have isn't functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port on the steering wheel. The majority of key fobs come with security features to make it harder for attackers clone and replicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle. In some instances, you can buy an alternative keyfob from an authorized dealer or another retailer. Your locksmith at your auto will then program it to work with your car. This is because most of the major US and Asian automobile manufacturers use key fob programming protocols with third-party companies who create the tools locksmiths for auto use to programme keys for their customers. Certain key fobs from the aftermarket may be advertised as being compatible with vehicles of all kinds. However, automotive locksmiths advise against using them since they are likely to work poorly or not work even work at all. They recommend buying fobs made specifically for your vehicle so that they will work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs. Vehicle Manufacturers' Programming Tools Automotive technologies have progressed a lot, and today's vehicles require computer technology in order to function. One key element of this technology is a transponder chipset that must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs with embedded security features that stop hot-wiring (like in a movie) and the car won't start without the right key. These key fobs are more complex than your traditional mechanical keys, which is why they are usually in the hands of a skilled, professional auto locksmith. The cost of a key fob may vary based on the vehicle model and the type of key however they usually cost between $85 and $400. This includes the labor required to program the key fob and the cost of any needed replacement parts. To make the process more complicated, these car key fobs make use of a special software to communicate with the car's onboard computer. The software blocks unauthorized access by only allowing the key to function only if it's been programmed for the specific car. This means that if you need your keys replaced, you'll need have the new key fob programmed to the car for it to work. This is accomplished by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool permits a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming devices can be an handheld device that is cheap or fancy and can do more than just program keys (like reading the eeprom file inside the ECU). Some people may attempt to program their keys themselves using these tools. However it's best to leave this task to a professional auto locksmith. If you're not aware of all the aspects of the various software systems, it's possible to accidentally alter 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 is old enough, you'll still have a key from the past to use to unlock the doors and turn off the ignition. Modern cars have transponders that must be recognized and accepted by the computer system before it can start. This is a further layer of security that prevents thieves from stealing the car and driving away with a stolen car. A licensed locksmith will have the right tools and software to create a key that is compatible with your car's security system. First, your locksmith will require a blank key that is compatible with the model and make 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 the car into a special programing mode, which allows locksmiths to connect a key to the system. To accomplish this, the key programming scanner will communicate with the car's computer to send a specific code. The computer will be able to recognize the code and add it to the list of keys that are approved. In some cases the scanner may also be able to delete lost or stolen keys from the system. The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. It is best to delegate it to a professional with experience with these systems. Locksmiths can program keys quickly using onboard programming. It can take as little as an hour if everything is done correctly. If the key isn't in good working order or the procedure isn't followed exactly, the process could take up to half an hour. There are many different key programmer scanners which can work with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their broad range of models for vehicles. However, neither can be programmed for every vehicle on the market. They are also expensive. It's a good idea purchase a computer that receives regular updates when the manufacturer introduces new technologies. In the event that your machine is not updated, it will become obsolete quickly.
