Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are used in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proven to be extremely successful in preventing car theft. It has also saved many car owners a lot of money because they don't need to replace their cars.

In the past, thieves would simply push your car's ignition switch into the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system entirely. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it transmits an electrical signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow and start the starter. begin the engine.

For instance the "smart key" which allows you to summon your car into tight parking spaces, like a Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual however, you'll typically require an auto locksmith to have a new one programmed in case yours stops functioning. A professional locksmith is better equipped to connect your computer to the vehicle via the OBD port located under the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to clone and replicate the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a new unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
