Automotive Locksmith Key Programming The majority of modern cars require some type 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 EEPROM or OBD2 programming. Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop software and hardware for locksmiths working in automotive vehicles. Transponder Chips Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has proven to be a huge success in preventing car theft. It also saves many car owners a lot of money since they don't need to replace their vehicles. The principle of the transponder system is to make it impossible for thieves to start your vehicle without a valid key.

These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip. When you insert the transponder keys into the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key.

Certain vehicles only recognize a certain type of transponder chips, depending on the manufacturer.
