Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and manufacturer, the process may be as simple as using an additional key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers share their programming protocol with auto tool makers, so they can design hardware or software for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio signals of low-level. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been an immense success in stopping auto theft. It also saves many car owners a lot of money since they don't have to buy new their cars.
The principle of the transponder system is to make it hard for thieves to start your vehicle without a valid key. In the past, car thieves would force the ignition switch of your car into the "on" position with an ordinary screwdriver or hot-wire the car to bypass the system entirely. These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert the transponder keys in the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed to detect the specific frequency of the chip within the key. The car's computer onboard will detect that the key is legitimate and allow the fuel to flow, then power the starter or start it.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. It is therefore important 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 should have a multi-vehicle key programming tool that is compatible with different car manufacturers and models. This is a less expensive option than purchasing specific tools for each type of vehicle. There are also specific key programming devices for automotive that are only suitable for specific brands of vehicles however they are not as popular. The best automotive locksmiths will have the appropriate tools to work on any type of vehicle, so be sure you find a reputable company that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to unlock doors and begin the engine with the push of a button. It is also possible to press buttons to activate features like trunk releases, door locks or fuel flap controls. Some fobs can be controlled using buttons. For instance the "smart key" which allows you to summon your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help of the user guide, however you'll need to call an automotive locksmith if the one you have isn't functioning. A professional locksmith is more equipped to connect the computer of your car via the OBD port on the steering wheel.
The majority of key fobs today come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on your key fob. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your vehicle.
In many instances, you can purchase an alternative key fob from the dealer or from another retailer and have it programmable by your locksmith in your car to fit your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who produce the tools used by auto locksmiths to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles However, the majority of locksmiths in the automotive industry do not recommend using them as they're likely to work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they work correctly and are less prone to issues like interference or incompatibility. This will save money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tool

The cost of a car key fob varies depending on the model and type of key, but is generally between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
To complicate the process to make the process more complicated, these key fobs for cars utilize a specific software system to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed for a specific car to work. If you replace your keys, you will have to program the new key fob into the car for it to function.
This is accomplished using a programing tool for car keys that is compatible with your vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter a programming mode. The key programming device could be an handheld device that is cheap or extravagant and can do more than just program keys (like reading the eeprom file in the ECU).
Although some people might attempt to program their own keys with these tools, this is something best left to a professional auto locksmith.

You can also program new keys using EEPROM. It is more complex and requires a thorough understanding of how electronic systems work. This is why it's best left to a professional who has extensive experience working on these types of systems.
