Automotive Locksmith Key Programming The majority of modern cars require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming. Most US and Asian automobile manufacturers share their programming protocols with auto tool makers to allow them to develop software and hardware for locksmiths in the automotive industry to use. Transponder Chips Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips which emit low-level radio waves. The microchips are equipped with a unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your vehicle does not recognize the signal it will shut down.

When you insert the transponder keys into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip within the key. The car's computer onboard will detect that the key is valid and allow the fuel to flow, then power up the starter, or even begin it. Depending on the manufacturer certain vehicles can only recognize a specific type of transponder chip. Therefore, it is essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.

This includes the labor to program the key fob as well as the costs for any necessary replacement parts. The car key fobs are more complicated due to the fact that they use an operating system that communicates with the computer onboard of the car. The software blocks access to unauthorised users by only allowing keys that have been programmed for a specific vehicle to work.

Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has knowledge of these systems. Onboard programming is the quickest method for locksmiths to program a new key. It can take less than a minute when everything is done correctly. However, if the key isn't in the right condition or the procedure isn't followed exactly, it can take up to a half hour.
