Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Based on the car's make and model, the procedure can be as easy as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers to allow them to develop hardware and software for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has been a huge success in preventing car theft. It has also saved many car owners a significant amount of money as they don't have to buy new their vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to get into your car without the right key. In the past, thieves would use a flat screwdriver to force the ignition switch of your vehicle into "on" mode, or hot-wire it to get around the system. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key in the ignition, the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed to detect the specific frequency of the chip within the key. The onboard computer of the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. It is therefore essential that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have a multi-vehicle key programming device that works with different car manufacturers and models.

The most reliable automotive locksmiths will have the proper equipment to tackle any type of vehicle, so ensure you find a reputable company with these kinds of tools.
Key FOBs

There are also buttons that you can press to trigger features like trunk release, door locks or fuel flap control. Certain fobs can be controlled using buttons. For instance, a "smart key" which allows you to summon your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the aid of a user's guide but you'll usually need an automotive locksmith to have a new one programmed if the one you have isn't working. A professional is better equipped to connect your computer to the vehicle to the OBD port on the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to duplicate and copy the signals that they transmit. They include pseudo-random sequence generators that generate an entirely new unlock code each time you press the button on the key fob. This is to prevent attackers from capturing and replaying the unlock signal in order to gain access to your car.
In certain instances, you can buy the replacement keyfob at a dealership or another retailer. Your locksmith at your auto will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party firms who create the tools used by auto locksmiths to program their customer's keys.

However, locksmiths for automotive recommend against using them because they're more likely to perform poorly or even not even work at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle so that you can be sure they'll function properly and be less prone to issues such as interfering or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.
