Automotive Locksmith Key Programming Modern cars need some kind of key programming. Depending on the model and manufacturer the procedure could be as simple as using an extra key to programme the computer onboard, or as complex as OBD2 programming or EEPROM. Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can develop software or hardware for automotive locksmiths. Transponder Chips Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has been extremely successful in preventing theft of cars. It has also saved many car owners a significant amount of money as they don't have to buy new their cars. The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, thieves would use an ordinary screwdriver to force the ignition switch in your car to go into "on" mode, or hot-wire it to evade the system. These types of thefts have been dramatically decreased with the introduction of the transponder chip. When you insert the transponder key into the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, power up the starter or begin it. Based on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your car's keys and remotes. A reputable locksmith for automotive needs to have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a cheaper alternative than buying specific tools for each model of vehicle. There are also specific key programming tools for automobiles that can only be used on one particular brand of vehicle however, they are less popular. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you select a reputable firm that has this kind of equipment. Key FOBs As the name suggests, key FOBs contain transponder chips programmable that enable your car to recognize 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 control of the fuel flap. Some fobs can be controlled by pressing buttons. For instance, a "smart key" which allows you to summon your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60. While some replacement key fobs can be programmed by you with the assistance of a user's manual, you'll often 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 equipment that is specialized and access to the programming tools needed to connect your car's computer through the on-board diagnostics (OBD) port beneath the steering wheel. The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on the key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle. In certain instances you can purchase an alternative keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because most of the major US and Asian car manufacturers use key fob programming protocols with third-party companies that make the tools that locksmiths utilize to program their customers' keys. Certain key fobs from the aftermarket may be marketed as being compatible with all vehicles. However, locksmiths for automotive recommend against using them because they are likely to work poorly or even not even work at all. Instead, they suggest buying fobs specifically designed for your vehicle so that you are certain they'll function correctly and are less susceptible to issues such as interfering or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs. Vehicle Manufacturers' Programming Tool Automotive technologies have advanced considerably, and today's vehicles require computer technology to function. One of the most important components 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. These key fobs have built-in security features that stop hot-wiring (like in a movie) and the car will not start if you don't have the proper key. These key fobs can be a little more complex than a traditional mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob will differ based on the vehicle model and the type of key however, they generally cost between $85 and $400. This includes the labor cost to program the keyfob as well as any replacement parts. To make the process more complicated the car key fobs utilize a specific software system to communicate with the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys that have been programmed specifically for a particular car to function. If you change your keys, you will need to program the new key fob to the car in order for it to function. This is accomplished by using a programming tool for car keys that is compatible with your vehicle's brand. This tool allows locksmiths to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming device can be a handheld device that is cheap or fancy and can do more than just programming keys (like reading the eeprom file inside the ECU). Some people may try to program their keys by themselves using these tools. However, this is best left to an experienced auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's very easy to make a mistake and alter settings that could cause damage to the vehicle.

This will put your car into the mode of programming which will allow the locksmith to add a new key to the system. The key scanner is programmed to communicate with the computer of the vehicle to send the code. The computer will be able to recognize this code and include it into the list of keys that are authorized. In some instances, a scanner can also remove keys that have been stolen or lost. Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional with experience with these systems. Onboard programming is the quickest way for a locksmith to program a new key. If everything is done correctly, it can take as little as one minute. If the key is not in good working order or the procedure isn't being followed precisely, the procedure could be as long as half an hour.
