see this require some type of key programming. Depending on the car's maker and model, the process can be as simple as programming onboard using a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian automobile manufacturers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. They have a unique 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 proved to be an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money as they don't need to replace their cars.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would use the flat screwdriver to push the ignition switch of your car into "on" mode or even hot-wire it to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it will transmit a signal that is received by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's onboard computer will then detect that the key is valid and allow the fuel to flow, then power up the starter, or even start it.
Based on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it is crucial to make sure that your locksmith in the automotive industry is equipped to program your car's key and fobs correctly.

The majority of key fobs today have security features that make it difficult for criminals to duplicate or duplicate the signals they transmit.
