Automotive Locksmith Key Programming Modern cars require some type 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 complicated as OBD2 programming or EEPROM. Most US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can create hardware or software for automotive locksmiths. Transponder Chips Most modern cars are equipped with transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a good amount of money as they do not have to purchase new cars. The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past car thieves would use an ordinary screwdriver to force the ignition switch in your car into the “on” mode, or hot-wire it in order to get around the system. These kinds of thefts have been drastically reduced with the introduction of the transponder chip. When you place the transponder key into the ignition, the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip inside the key. The computer onboard of the car will then recognise the key as valid and will allow fuel flow and power the starter to start the engine. Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the right equipment to program your car's keys and remotes. A good automotive locksmith will possess a multi-vehicle programing device which can be used with different models and brands of cars. This is a much cheaper option than buying individual tools for each brand of vehicle. They are not as common, but there are specialised automotive key programming tools that can only work on a specific model of vehicle. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so be sure you choose a reputable business with these kinds of tools. Key FOBs Key FOBs are programmeable transponder chip devices that allow your vehicle to unlock doors and start the engine using the push of a button ignition. It is also possible to press buttons to activate features such as trunk releases, door locks or fuel flap controls. Certain fobs can be controlled with the press of buttons. For instance the “smart key” that allows you summon your car into tight parking spaces, such as a Tesla or Genesis GV60. While certain replacement key fobs can be programmed with the help of a user manual, you'll often require an auto locksmith to get a new one programmed if yours stops working. This is because a professional locksmith has the specialized equipment and access to the programming tools needed to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel. The majority of key fobs are equipped with security features to make it harder for attackers duplicate and copy the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle. In many cases you can purchase an alternative key fob from the dealer or other retailer and then have it programmed by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who make the tools used by locksmiths for programming their customers' keys. Certain aftermarket key fobs can be advertised as being compatible with vehicles of all kinds. However, locksmiths for automotive recommend against using them because they are likely to work poorly or even not even work 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 in the end by avoiding costly repairs or replacing your fobs.
