Automotive Locksmith Key Programming Modern cars need some form of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming. Most US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop hardware and software for automotive locksmiths to use. Transponder Chips Transponder chips are in a variety of newer vehicles to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips have a unique serial number that authenticates your key when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proven to be an enormous success in preventing auto theft. It also saves many car owners a lot of money since they don't have to buy new their cars. The transponder system's basic idea is to make it impossible for thieves to get into your vehicle without the correct key. In the past, thieves used the flat screwdriver to push the ignition switch of your car to go into “on” mode, or wire it hot to evade the system. These kinds of thefts have drastically reduced 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 hidden within the barrel. This antenna is programmed to read the specific frequency of the chip inside the key. The onboard computer of the car will recognize the key as being valid and allow fuel flow, power the starter or start the engine. Depending on the manufacturer some vehicles will only recognise a specific type of transponder chip. This is why it is crucial to make sure that your locksmith in the automotive industry has the right equipment to program your vehicle's keys and fobs properly. A reputable locksmith for cars should have a multi-vehicle key programming tool that can work on many different car manufacturers and models. This is a more cost-effective solution than buying individual tools for every brand of vehicle. These are less common however, there are specialist automotive key programmers that can only be used on a specific brand of vehicle. The top automotive locksmiths have the right tools to deal with any kind of vehicle, so be sure you choose a reputable business that offers these types of tools. Key FOBs Key FOBs are programmeable transponder chip devices that permit your vehicle to unlock doors and start the engine using the push of a button ignition. You can also press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Some fobs can be controlled by pressing buttons. For instance the “smart key” that lets you call your car to parking spaces, like a Tesla or Genesis GV60. While certain replacement key fobs can be programmed by you using the assistance of a user's manual but you'll usually require an auto locksmith to have a new one programmed if yours stops functioning. This is because a professional locksmith has the right equipment and access to the tools for programming needed to connect your car's computer to the OBD (OBD) port located beneath the steering wheel. Today, most key fobs include security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. Some key fobs have pseudo-random code generators which generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle. In some cases you can purchase the replacement keyfob at an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that produce the tools used by locksmiths for programming their customers' keys. Although some key fobs from the aftermarket are advertised as compatible with all vehicles, most automotive locksmiths don't recommend using them since they're likely to work poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they function properly and are less prone to issues such as interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs. Vehicle Manufacturers' Programming Tools The automobile industry has made significant advancements in the past few decades. Today's vehicles are computer-driven. One key element of this technology is a transponder chip which requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to work. These key fobs are equipped with security features to stop hot-wiring, like in a movie. The car will not start if the keys are not correct. These key fobs are more complex than your traditional mechanical keys and are the reason they are usually in the hands of an expert, professional auto locksmith. The cost of a car key fob varies according to the model and type of key, but is generally between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts. Car key fobs are more intricate because they use a software system that works with the computer onboard of the car. The software prevents unauthorized access by allowing the key to function if it has been programmed to that specific car. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car for it to work. This is accomplished by using a tool for programming car keys that is compatible with the vehicle's brand. This tool allows a locksmith to connect to the OBD port in the vehicle and then enter the programming mode. The key programming device can be a handheld device that's affordable or fancy and can do more than just program keys (like reading the eeprom file in the ECU). Some people may try to program their keys on their own using these tools. However it's best to leave this task to an experienced auto locksmith. It's easy to make mistakes with the software systems if you don't understand the nuances. This can lead to damage. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these problems. On-Board programming If your car is older than you, you'll still have a traditional metal key that you can use to open the doors and turn over the ignition. Modern cars have a transponder that must be recognized and accepted by the computer system in order to start. This is an additional layer of security to keep thieves from starting and then driving off with a stolen vehicle. A certified locksmith will have the right tools and software to program a new key that works with the security system in your car. The locksmith needs to purchase a blank key that is compatible with the make and model of your vehicle. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put the vehicle into an exclusive programming mode which will allow the locksmith to add a new key to the system. To accomplish this, the key programmer scanner will communicate with the car's computer and send an exact code. The computer will be able to recognize the code and add it to the list of approved key. In some cases, a scanner can also erase keys that were stolen or lost. 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. This is why it's best left to a professional that has years of expertise working on these types of systems. Locksmiths can program keys quickly with onboard programming. It takes as little as an hour if everything is done correctly. However, if the key isn't in correct condition or the procedure isn't strictly followed, it could take up to a half hour. There are many key programmer scanners available that support different vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their wide range of vehicle models. However, no system can be programmed for every vehicle on the market. Furthermore, these systems cost a lot. It's a good idea purchase a programer that is updated regularly as the manufacturer develops new technologies. Your programming machine will quickly become obsolete if you don't do this.
