Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Based on the car's make and model, the procedure can be as simple as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car makers use the same programming protocols as auto tool makers in order to create software and hardware for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has been an enormous success in preventing car theft. It also saves many car owners a significant amount of money because they don't need to replace their cars.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without a key. In the past, car thieves would use a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode, or wire it hot to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you place the transponder key into the ignition, the signal is picked up by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then detect that the key is genuine and allow the fuel to flow, then power up the starter, or even start it.
Depending on the manufacturer some vehicles will only recognise the specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your car's keys and remotes.
A good automotive locksmith will utilize a multi-vehicle programmable device which can be used on many different automobile models and manufacturers. This is a much cheaper option than buying individual tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programmers that are able to only work on a specific brand of vehicle. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
The name implies that key FOBs house the programmable transponder chips that enable your vehicle to identify and unlock the doors, or start the engine with a push-button ignition. It is also possible to press buttons to activate features like door locks, trunk releases or control of the fuel flap. Some fobs have additional functions that can be controlled with the push of a button for example, a "smart" key fob that lets you get your car into parking spaces that are difficult to access, like you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the assistance of a user's manual but you'll usually need an automotive locksmith to get a new one programmed in case yours stops working. A professional is better equipped to connect the computer of your car via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a different unlock code every time you press the button. This prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.
In certain instances you can purchase the replacement keyfob at an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who produce the tools used by locksmiths for programming their customers' keys.
While some aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them since they're likely to work poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your vehicle, so that you can be certain they'll function correctly and are less susceptible to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Tool for Programming Vehicle Manufacturers'
The automotive industry has advanced considerably and today's vehicles need computers to function. Transponder chips are an essential part of this technology. It needs to be programmed by a locksmith, mechanic, or dealer to work. These key fobs have built-in security features that will prevent hot-wiring (like in a film) and the car won't start if it doesn't have the right key.
These key fobs are a bit more complicated than a traditional mechanical key and are the reason you'll usually find them in the hands of an expert professional auto locksmith. The cost of the car key fob can vary according to the model and type of key, but is generally between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more complicated, these car key fobs use a special software system to connect to the car's onboard computer. reprogram car key prevents unauthorised access by only allowing keys programmed for a specific car 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 using a programing tool for keys for cars that are 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 the programming mode. The key programming tool could be a handheld device that is inexpensive device or a more expensive one that is capable of performing many things beyond just key programming (like reading and cloning the eeprom files in the ECU).
Some people may attempt to program their keys on their own using these tools. However this should be left to an expert auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's possible to make a mistake and alter settings that could cause damage to the vehicle.

On-Board Programming
If your car is old enough, you'll still have a key from the past that you can use to open the doors and turn over the ignition. Modern cars come with a transponder that must be acknowledged and accepted by the computer system to start. This is a further security measure to prevent thieves from starting and driving away with a stolen car. A certified locksmith will have the right tools and software to program a new key that is compatible with the security system in your car.

Once the key is in hand the locksmith will connect the programming scanner to the diagnostic port of your car. This will put your vehicle into a specific programming mode, which allows the locksmiths to add the key to the system.
The key scanner is programmed to communicate with the computer of the vehicle to send a code. The computer will recognize the code and add it to the list of approved key. In some cases the scanner will also remove keys that have been stolen or lost.
You can also program new keys using the EEPROM. It is more complex and requires a thorough understanding of how electronic systems work. This is why it should be left to a professional who has years of experience working with these kinds of systems.
Locksmiths can program a key quickly by using onboard programming. If everything is done correctly, it can take just one minute. If the key is not in the right condition or the procedure isn't followed exactly, the process can take as long as a half 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 extremely popular among locksmiths due to their wide range of models for vehicles. However, neither will be able to program every single vehicle that exists. They are also expensive. It's a good idea purchase a programer that will get regular updates as the manufacturer develops new technologies. Your programming machine will quickly become outdated if you don't take this step.
