Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, which means they can develop software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio signals. The microchips have a unique serial number which authenticates your keys when you connect it to the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has proven to be an incredible success in preventing auto theft. It has also saved many car owners a lot of money because they don't have to buy new their cars.
The transponder system's basic idea is to make it difficult for thieves to open the doors of 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 entirely. Transponder chips have dramatically reduced these types of thefts.
When you insert the transponder key in the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed so that it can detect the specific frequency of the chip inside the key. The onboard computer of the car will then recognise the key as valid and will allow fuel flow, power the starter or begin the engine.
Some vehicles only recognize a certain type of transponder chip according to the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the right equipment to program your car's keys and remotes.
A reliable locksmith for cars will utilize a multi-vehicle programmable device that can be used with different models and brands of cars. This is a less expensive option than purchasing separate tools for each brand of vehicle. They are not as common however, there are specialist automotive key programmers that can only be used on a specific brand of vehicle. The top automotive locksmiths have the proper tools to work on any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
As the name implies, key FOBs house the transponder chips that can be programmed to enable your vehicle to identify and unlock the doors or start the engine with a push-button ignition. They also have buttons you can press to activate features like door locks, trunk release or fuel flap control. Certain fobs come with additional functions that can be controlled with the button presses for example, the "smart" key fob that allows you to bring your car to parking spots that are tight as you would with the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual, you'll often need an automotive locksmith to get a new one programmed in case yours stops working. This is because a professional has the right equipment and access to the tools for programming needed to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
Today, most key fobs have security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a different unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase a replacement keyfob from an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your car. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that produce the tools used by locksmiths who program their customer's keys.
Certain key fobs from the aftermarket may be marketed as being compatible with all vehicles. However, professional locksmiths strongly discourage using them as they're likely to function poorly or even not at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less susceptible to issues such as interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.

These key fobs are a little more complex than the traditional mechanical key, which is why they are usually in the hands of a reputable, professional auto locksmith. The cost of the car key fob can vary according to the type and model of key, but it is usually between $85 to $400. This includes the cost of labor to program the key fob as well as the costs for any necessary replacement parts.
To complicate the process to make the process more complicated, these key fobs for cars utilize a specific software system to connect to the car's onboard computer. The software prevents unauthorised access by only allowing keys that have been programmed for a specific vehicle to work. If you replace your keys, you will have to program the new key fob to the car to allow it to work.
This is accomplished using a programming tool for car keys that is compatible with the vehicle's brand. This tool allows locksmiths to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming device could be an handheld device that is inexpensive or one that is sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).

The computer will be able to recognize this code and add it to the list of approved key. In some instances, the scanner will also be able to delete keys that have been stolen or lost from the system.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires an in-depth understanding of how electronic systems work. This is why it should be left to a professional that has extensive expertise working on these types of systems.
Locksmiths can program keys quickly by using onboard programming. If everything is done properly, 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 up to half an hour.

Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of vehicle models. The system cannot program every vehicle. These machines are also quite expensive.
