Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and make the procedure could 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 car makers share their programming protocols with auto tool manufacturers in order to create hardware and software for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have transponder chips to stop car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique serial number which authenticates your key whenever you connect it to the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has been an enormous success in preventing auto theft. This technology has also saved car owners a great amount of money as they do not have to buy new vehicles.
The transponder system's basic idea is to make it hard for thieves to get into your vehicle without a valid key. In the past, thieves would force your ignition switch to the "on" position with a flat screwdriver or even make use of hot-wires to bypass the system altogether. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you place the transponder key in the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip inside the key. The car's computer onboard will recognise that the key is valid and allow fuel to flow, power up the starter or start it.
Certain vehicles only recognize a certain type of transponder chips depending on the manufacturer. This is why it is important to ensure that your locksmith for automotive has the right equipment to program your vehicle's keys and fobs correctly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that can work on many different models and car brands. This is a less expensive solution than buying specific tools for each type of vehicle. There are also specific key programming tools for automobiles that can only be used on specific models of vehicles however, they are less frequently used. The top automotive locksmiths have the proper tools to work on any type of vehicle, so ensure you choose a reputable firm that offers these types of tools.
Key FOBs
The name implies that key FOBs are home to the programmable transponder chips that enable your car to recognize and unlock the doors or start the engine using push-button ignition. They also have buttons you can press to trigger features like door locks, trunk release or control of the fuel flap. Some fobs also have additional functions that can be controlled with the push of a button for example, a "smart" key fob that allows you to summon your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the aid of a user's guide, you'll often require an auto locksmith to get a brand new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect your computer to the car via the OBD port under the steering wheel.
The majority of key fobs come with security features that make it difficult for attackers to clone and replicate the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code each time you press the button on your key fob. This prevents attackers capturing and replaying the unlock signal to gain access to your car.
In most cases you can buy a replacement key fob from the dealer or from another retailer and then have it programmed by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that produce the tools used by locksmiths for programming their customers' keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, locksmiths for automotive recommend against using them because they're more likely to perform poorly or not work even work at all. Instead, they recommend purchasing fobs designed specifically for your vehicle, so that you can be sure they'll function properly and be less susceptible to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.

The cost of a car key fob varies depending on the model and type of key, but is typically between $85 to $400. This includes the labor cost to program the keyfob and any replacement parts.
Car key fobs are more complicated because they utilize software that interacts with the computer onboard of the car. The software blocks access by unauthorised persons by only permitting keys that have been programmed for a specific vehicle to work. This means that if you get your keys replaced, you'll need to have the new key fob programmed to the car to function.
This is accomplished by using a programming tool for car keys that is compatible with your vehicle's brand. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming tool could either be an inexpensive handheld device or a more expensive one that can perform various things that go beyond key programming (like reading and cloning Eeprom files within the ECU).

You can also program new keys by using the EEPROM. It is more complex and requires a thorough understanding of electronic systems. This is why it's best left to a professional that has extensive expertise working on these types of systems.
Locksmiths can program a key quickly by using onboard programming. It takes as little as a minute when everything is completed correctly. If the key isn't in the right condition or the procedure is not adhered to, it could take up to an hour.
