Automotive Locksmith Key Programming Modern cars need some kind of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming using a spare key that works or as complicated as EEPROM or OBD2 programming. Most US and Asian car makers share their programming protocols with auto tool manufacturers in order to create tools and hardware for locksmiths working in automotive vehicles. Transponder Chips The majority of newer cars have transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio signals. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. It also saves many car owners a lot of money as they don't have to replace their vehicles. The principle behind the transponder system is to make it difficult for thieves to open the doors of your car without a key. In the past car thieves used a flat screwdriver to force the ignition switch of your car into the “on” mode, or wire it hot to evade the system. These types of thefts have been dramatically decreased with the introduction of the transponder chip. When you place the transponder key into the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The car's onboard computer will then detect that the key is legitimate and allow fuel to flow, turn up the starter, or even begin it. Based on the manufacturer, certain vehicles can only accept certain types of transponder chip. This is why it is important to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs correctly. A reputable locksmith for cars should have a multi-vehicle key programming tool that works with different models and manufacturers of cars. This is a cheaper option than buying separate tools for each type of vehicle. These aren't as popular however, there are specialist automotive key programming tools that can only work on a particular model of vehicle. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you select a reliable company that is equipped with this kind of equipment. Key FOBs The name implies that key FOBs are home to the programmable transponder chips that allow your vehicle to identify and unlock the doors, or start the engine with a push-button ignition. You can also use the buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Certain fobs can be controlled by pressing buttons. For instance, a “smart key” that lets you call your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60. While some replacement key fobs can be programmed by you using the assistance of a user's manual but you'll usually require an automotive locksmith to have a new one programmed if the one you have isn't working. This is because an expert locksmith has the specialized equipment and access to the programming tools needed to connect your car's computer via the on-board diagnostics (OBD) port located beneath the steering wheel. Today, most key fobs include security features that make it difficult for attackers to duplicate or copy the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a different unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle. In many instances you can buy an additional key fob at the dealership or another retailer and have it programmable by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party companies who create the tools used by locksmiths who program their customers' keys. While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them since they are likely to function poorly or not at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less susceptible to issues such as interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs. Tool for programming the vehicle manufacturers Automotive technologies have progressed a lot and modern vehicles require computer technology to function. One of the key components of this technology is a transponder chip which must be programmed into the vehicle by a locksmith or dealer/mechanic in order to function. These key fobs have built-in security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the correct key. These key fobs can be a little more complex than a traditional mechanical key. This is why they're usually handled by experienced, professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the key type however, they generally cost between $85 to $400. This includes the cost of labor to program the key fob and the cost of any needed replacement parts. These car key fobs are more complicated because they utilize a software system that works with the computer onboard of the car. The software prevents unauthorized access by only permitting the key to function only if it's been programmed to the car in question. If you change your keys, you'll have to program the new key fob to the car in order for it to work. The most common method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a fancy one that can do a wide range of things beyond key programming (like reading and cloning the eeprom files in the ECU). Although some people might attempt to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. It is easy to make mistakes with the software systems if you aren't aware of the nuances. This can lead to damage. The most important thing to remember is that a professional with experience can help you avoid these issues. On-Board programming If your vehicle is old enough that you'll have a traditional metal key to open the doors and turn off the ignition. Modern cars come with transponders that must be acknowledged and accepted by the computer system to start. This is a further layer of security that prevents thieves from stealing the car and then driving off with a stolen vehicle. A licensed locksmith will have the right tools and software to program a new key that works with the security system of your vehicle. Your locksmith will need to obtain an uncut key that is compatible with your vehicle's model and make. Once the key is received, your locksmith will link the programming scanner to your car's diagnostic port. This will put your car into the mode of programming that allows the locksmith to add a new key to the system. The key scanner is programmed to communicate with the computer in the vehicle to transmit a code. The computer will be able to recognize the code and add it to the list of keys that are approved. In some cases, a scanner can also delete lost or stolen keys. You can also program new keys by using EEPROM. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional who has extensive expertise working on these types of systems. Locksmiths can program a key quickly with onboard programming. It can take less than 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 as long as a half hour. There are numerous key programmer scanners available that support different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both very well-liked by locksmiths due to the fact that they support a broad range of automobile models. However, no system can program every vehicle on the market. They are also expensive. It's best to purchase a programmer which will receive regular updates from the manufacturer whenever new technologies are introduced. If not, your computer will become obsolete quickly.
