Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are tiny computer microchips that emit radio signals at a low level. The microchips are equipped with an unique serial number that authenticates your keys 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 an immense success in stopping auto theft. This technology has also helped car owners save a huge amount of money as they do not have to purchase new cars.
The basic idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past car thieves used an ordinary screwdriver to force the ignition switch of your car into "on" mode or even hot-wire it in order to evade the system. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys in the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The onboard computer in the car will then recognize the key as valid and will allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. This is why it is important to ensure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs properly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that can work on many different car manufacturers and models.

The most reliable automotive locksmiths will have the right tools to work on any type of vehicle, so be sure you choose a reputable firm with these kinds of tools.
Key FOBs

It is also possible to press buttons to activate features such as trunk releases, door locks or control of the fuel flap. Certain fobs can be controlled by pressing buttons. For example an "smart key" which allows you to summon your car to parking spaces, such as a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from the user guide, however you'll need to call an automotive locksmith if yours isn't working.

The majority of key fobs today include security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random generators that generate a new unlock code every time you press the button on the key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some instances, you can buy an alternative keyfob from more info an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your vehicle.

Vehicle Manufacturers' Programming Tool

Key fobs come with built-in security features that prevent hot-wiring (like in a film) and the car will not start if you don't have the correct key.

The cost of a key fob will vary depending on the car model and the key type however they usually cost between $85 and $400. This includes the labor cost to program the keyfob, as well as any replacement parts.
To complicate the process, these car key fobs utilize a specific software system to work with the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys that have been programmed specifically for a particular car to function. If you replace your keys, you will need to program the new key fob in the car for it to function.
This is accomplished by using a programming tool for car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. The key programming tool can be a handheld device that is inexpensive device or a more expensive one that can perform various things beyond key programming (like reading and cloning the eeprom files in the ECU).
While some may try to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's very easy to accidentally alter settings that could potentially damage the vehicle. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these issues.
On-Board programming
If your car is old enough that it has a key, it might still come with a metal key that can be used to open doors and turn off the ignition.

This is an extra layer of security that prevents car thieves from stealing a car and then driving off with it. A locksmith who is certified will have the necessary tools and software to create a new key that is compatible with the security system in your car.

The computer will recognize the code and add it to the list of keys that are approved. In certain instances, the scanner will also be able to erase lost or stolen keys from the system.
You can also program new keys with EEPROM. It is more complex and requires a deep understanding of how electronic systems work. This is why it's best left to a professional who has years of experience working with these kinds of systems.
Locksmiths can program a key quickly using onboard programming. When everything is done correctly it can take just one minute. If the key is not in the correct condition or the procedure isn't being followed exactly, the process can take up to half an hour.
There are a variety of key programmer scanners that support different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their broad range of vehicle models. The system cannot program every vehicle. In addition, these machines cost a lot. It is a good idea to purchase a computer that is updated regularly when the manufacturer introduces new technologies.
