Automotive Locksmith Key Programming Modern cars need some kind of key programming. Based on the model and manufacturer, the process may be as simple as using an extra key to programme the computer onboard, or as complex as OBD2 programming or EEPROM. The majority of US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop software and hardware for locksmiths in the automotive industry to use. Transponder Chips The majority of newer cars have transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. They have a unique digital serial number that authenticates the key to your vehicle 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 enormous success in preventing auto theft. This technology has also saved car owners a great deal of money as they do not have to replace their vehicles. The principle of the transponder system is to make it hard for thieves to start your car without the right key. In the past car thieves would use a flat screwdriver to force the ignition switch in your car into the “on” mode, or wire it hot to bypass the system. Transponder chips have drastically decreased the likelihood of theft. When you insert a transponder keys into the ignition, it transmits an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip inside the key. The computer onboard of the car will then recognize the key as being valid and will allow fuel flow and power the starter to start the engine. Some vehicles only recognize specific type of transponder chip, depending on the manufacturer. This is why it is crucial to make sure that your locksmith in the automotive industry has the appropriate equipment to program your vehicle's keys and fobs correctly. transponder key programming for automotive will have a multi-vehicle programming tool that can be used with different car models and manufacturers.

Certain fobs come with additional functions that can be controlled using the press of a button for example, the “smart” key fob that lets you bring your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.

The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals that they transmit. Certain key fobs feature pseudo-random code generators that generate a unique unlock code each time you press the button.

It is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional who has knowledge of these systems. Locksmiths can program a key quickly by using onboard programming. When 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. There are a variety of key programmer scanners which can work with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their broad range of vehicle models. However, neither will be able to program every single vehicle that exists.
