Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers use the same programming protocols as auto tool manufacturers, so they can create tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are small computer microchips which emit radio signals of low-level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a good amount of money since they don't have to purchase new cars.
The principle of the transponder system is to make it difficult for thieves to open the doors of your car without the right key. In the past, car thieves would simply push the ignition switch of your car into the "on" position using a flat screwdriver or even use hot wires to disable the system altogether. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will then recognise the key as valid and will 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. This is why it's crucial to make sure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs correctly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that is compatible with different car manufacturers and models. This is a far cheaper option than buying separate tools for each type of vehicle. There are also specific key programming devices for automotive that can only be used on one particular brand of vehicle, but these are less popular. The top automotive locksmiths are equipped to work on any vehicle. Be sure to choose a reputable firm that has this type of equipment.
Key FOBs

There are also buttons that you can push to activate features such as door locks, trunk release or fuel flap control. Some fobs also have additional functions that can be controlled using the press of a button, such as the "smart" key fob that allows you to get your car into parking spaces that are difficult to access as you would with a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help of the user guide, however you'll need to call an automotive locksmith if the one you have isn't working. A professional is better equipped to connect your computer to the car via the OBD port under the steering wheel.
Today, most key fobs have security features that make it difficult for hackers to duplicate or copy the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a unique unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In most instances you can buy a replacement key fob from the dealer or from another retailer and have it programmed by a locksmith for your vehicle to fit your specific vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party companies who make the tools used by locksmiths who program their customer's keys.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths advise against using them since they're more likely to perform poorly or even not at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Tool for Programming Vehicle Manufacturers'

These key fobs have built-in security features that will prevent hot-wiring (like in a film) and the car won't start without the proper key.
Key fobs are more complex than the traditional mechanical keys and that's why you'll usually find them in the hands of a skilled, professional auto locksmith. The cost of a key fob will vary depending on the car model and the key type, but they typically run between $85 to $400. This includes the labor cost to program the keyfob as well as any replacement parts.
To make the process more complicated the car key fobs make use of a special software to communicate with the car's onboard computer. The software blocks access to unauthorised users by only allowing keys programmed specifically for a particular car to function. If you decide to get more info replace your keys, you will need to program the new key fob to the car to allow it to function.
The most common method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. The key programming tool could be a handheld device that is inexpensive device or a high-end one that is capable of performing various things that go beyond key programming (like reading and cloning the Eeprom files within the ECU).
While some may try to program their own keys using these tools, it's a job best left to an experienced auto locksmith.

Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. It is best to delegate it to a professional with knowledge of these systems.

There are many different key programmer scanners that can be used with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their wide range of vehicle models. The system cannot program every vehicle.
