Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on your vehicle's model and make, the process may be as simple as using a spare key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian car makers have programming protocols that they share with auto tool manufacturers in order to create hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips which emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a good amount of money since they don't have to purchase new cars.

In the past, car thieves would simply force the ignition switch of your car into the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system completely. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits a signal that is received by a hidden antenna around the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip inside the key. reprogram car key of the car will then recognise the key as being valid and allow fuel flow and power the starter to start the engine.
Depending on the manufacturer some vehicles will only recognise certain types of transponder chip. This is why it's essential to ensure that your locksmith in the automotive industry is equipped to program your car's keys and fobs properly.

For example the "smart key" that allows you summon your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the help of a user manual but you'll usually require an automotive locksmith to get a brand new one programmed in case yours stops working. This is because a professional locksmith has the right equipment and access to the programming tools needed to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
Today, most key fobs include security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code each time you press the key fob's button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.

Certain key fobs from the aftermarket may be advertised as being compatible with all vehicles. However, professional locksmiths recommend against using them because they're likely to function poorly or not work at all.

This will save you money over the long term by avoiding expensive repairs or replacing your fobs.

This includes the labor required to program the key fob and the costs for any necessary replacement parts.

The software prevents unauthorised access by only allowing keys programmed for a specific vehicle to work. This means that if you need your keys replaced, you'll need have the new key fob programed to the car in order for it to function.
This is done by using a programming tool for keys for cars that are compatible with the vehicle's brand. This tool permits a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. The key programming tool can be a simple handheld device or a high-end one that can do many things beyond key programming (like reading and cloning the Eeprom files within the ECU).

Unless you're familiar with all the aspects of the various software systems, it's easy to make a mistake and alter settings that could potentially damage the vehicle.

EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of how electronic systems work. This is why it should be left to a professional that has extensive expertise working on these types of systems.
