Automotive Locksmith Key Programming Modern cars require some type of key programming. Based on the model and make the process could be as simple as using a spare key to program the onboard computer or as complex as OBD2 programming or EEPROM. The majority of US and Asian car manufacturers share their programming protocols with auto tool manufacturers so that they can develop tools and hardware for locksmiths working in automotive vehicles. Transponder Chips Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be a huge success in preventing car theft. This technology has also saved car owners a great amount of money since they don't have to replace their vehicles. The transponder system's basic idea is to make it impossible for thieves to open the doors of your car without the right key. In the past car thieves would use a flat screwdriver to force the ignition switch of your vehicle into “on” mode, or hot-wire it in order to evade the system. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip. When you insert the transponder key into the ignition the signal is received 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 computer onboard of the car will then recognise the key as valid and allow fuel flow and power the starter to begin the engine. Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer.

Some fobs have additional functions that can be controlled by the press of a button like a “smart” key fob that lets you get your car to parking spots that are tight similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60. You can program spare key fobs by yourself with the help from a user guide, but you will need to call an automotive locksmith in the event that yours isn't working.

The majority of key fobs today have security features that make it difficult for criminals to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators, which generate a unique unlock code each time you press the button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your vehicle. In many cases you can buy an alternative key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to work with your particular vehicle.

The most common way to accomplish this is using a car key programming tool that is compatible with the brand of the vehicle.
