Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the model and make, the process may be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers in order to create tools 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 tiny computer microchips that emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proven to be an enormous success in preventing car theft. It has also saved many car owners a lot of money since they don't have to buy new their vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would force your car's ignition switch into the "on" position with an ordinary screwdriver or make use of hot-wires to bypass the system entirely. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it will send a signal that is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognise the key as being valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the appropriate equipment to program your car's keys and remotes.

The majority of key fobs today include security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the button on the key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
