Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make the process could be as simple as using a spare key to program the onboard computer or as complex as EEPROM or OBD2 programming.
Most US and Asian car makers have programming protocols that they share with auto tool makers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are small computer microchips that emit low-level radio signals. They have a unique serial number which authenticates your key when you insert it into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proven to be extremely successful in preventing car theft. This technology has also helped car owners save a huge amount of money since they don't have to buy new vehicles.
The principle of the transponder system is to make it impossible for thieves to start your car without the right key. In the past, car thieves would force your car's ignition switch into the "on" position using an ordinary screwdriver or use hot wires to disable the system altogether. These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert the transponder keys in the ignition, the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will recognise that the key is legitimate and allow the fuel to flow, then power up the starter, or even begin it.
Some vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore essential that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.

You can also press buttons to activate features such as door locks, trunk releases or fuel flap controls. Certain fobs can be controlled by pressing buttons. For instance, a "smart key" that allows you summon your car into tight parking spaces, such as a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual, you'll often need 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 OBD (OBD) port located beneath the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to clone and replicate the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.

However, locksmiths for automotive strongly discourage using them as they're likely to function poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your vehicle so that you can be certain they'll function properly and be less susceptible to issues like interfering or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing your fobs.

Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional who has knowledge of these systems.
Onboard programming is the fastest way for a locksmith to program an entirely new key. When everything is done correctly, it can take as little as one minute. If the key is not in good working order or the procedure isn't being followed exactly, the process can take up to half an hour.
There are numerous key programmer scanners that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their wide selection of models for vehicles. However, no system will be able to program every vehicle on the market. These machines are also quite expensive.
