Automotive Locksmith Key Programming Modern cars need some kind of key programming. Based on the model and make the procedure could be as simple as using an extra key to program the onboard computer, or as complicated as OBD2 programming or EEPROM. Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop tools or hardware for automotive locksmiths. car key programming Transponder chips are used in many newer cars to stop theft of cars. These are tiny computer microchips which emit radio waves of low-level. 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 isn't able to recognize the signal and the engine is shut down. This technology has proven to be a huge success in preventing theft of cars.

These types of thefts have been drastically reduced with the introduction of the transponder chip. When you insert the transponder keys into the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip in the key.

If you decide to replace your keys, you will have to program the new key fob in the car to allow it to function. This is accomplished using a programing tool for car keys that is compatible with the 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 tool can either be an inexpensive handheld device or a more expensive one that is capable of performing various things beyond key programming (like reading and cloning the EEEPROM files in the ECU).

If the key isn't in the right condition or the procedure isn't strictly followed, it could take as long as a half hour. There are many different key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they cover a wide range of vehicle models.
