Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Based on the model and make, the process may be as simple as using an additional key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
The majority of newer cars have what are called transponder chips to stop car theft. These are tiny computer microchips that 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 vehicle does not recognize the signal and the engine is shut down. This technology has been a huge success in preventing car theft. It also saves many car owners a lot of money as they don't have to buy new their vehicles.

Transponder chips have dramatically reduced these types of thefts.
When you place the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer in the car will then recognize the key as being valid and will allow fuel flow and start the starter. start the engine.
Some vehicles only recognize a specific type of transponder chip according to the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
