Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian car makers share their programming protocols with auto tool manufacturers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are found in a lot of modern cars to prevent car theft. These are microchips in the form of computers which emit radio signals of low-level. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money by not having to buy new vehicles.
The fundamental idea behind the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, thieves would force the ignition switch of your car into the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system altogether. These types of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will send an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The onboard computer of the car will then recognize the key as valid and will allow fuel flow, power the starter or start the engine.
Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. This is why it's crucial to make sure that your locksmith in the automotive industry has the right equipment to program your vehicle's keys and fobs correctly.
A reliable locksmith for cars will have a multi-vehicle programming tool that can be used on many different car models and manufacturers.

This is to prevent attackers from capturing and playing back the unlock signal to gain access to your car.
In most cases you can purchase an alternative key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to work with your particular vehicle. This is because most of the major US and Asian car manufacturers share their key fob programming protocols with third-party companies who produce the tools auto locksmiths utilize to program their customers' keys.
