Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the procedure could 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 share their programming protocols with auto tool manufacturers so that they can develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates your keys when you plug it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has been an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money as they don't have to replace their cars.
The transponder system's basic idea is to make it hard for thieves to open the doors of your vehicle without the correct key. In the past, car thieves used the flat screwdriver to push the ignition switch in your car to go into "on" mode or even hot-wire it to evade the system. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder keys into the ignition, it transmits an electrical signal that is received by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The onboard computer of the car will then recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it's important to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs correctly.
A good automotive locksmith should have a multi-vehicle key programming tool that works with different models and car brands. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. There are also specific automotive key programmer devices that can only be used on specific brands of vehicles however they are not as popular. The top automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose an established company that has this type of equipment.
Key FOBs
The name implies that key FOBs contain 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 activate features such as door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled by the button presses for example, a "smart" key fob that lets you bring your car into tight parking spots similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
While some replacement keys can be programmed with the aid of a user's guide, you'll often require an auto locksmith to get a new one programmed in case yours stops working.

The majority of key fobs are equipped with security features that make it difficult for attackers to duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators which generate a new 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 the replacement keyfob at an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car.

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 the fobs.
Vehicle Manufacturers' Programming Tool
The automobile industry has made significant strides in the last few decades. Today's cars are computer-driven. One key element of this technology is a transponder chipset that needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs come with built-in security features that prevent hot-wiring (like in a movie) and the car won't start without the proper key.
These key fobs are a bit more complex than your traditional mechanical key and are the reason you'll usually find them in the hands of an expert professional auto locksmith. The cost of a key fob may vary based on the vehicle model and the key type, but they typically run between $85 to $400. This includes the cost of labor to program the key car key programming fob and the costs for any required replacement parts.

If you change your keys, you'll have to program the new key fob into the car to allow it to function.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool permits a locksmith to connect to the OBD port of the vehicle and then enter programming mode. The key programming device can be a handheld device that's cheap or extravagant and can do more than just program keys (like reading the eeprom file inside the ECU).

The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It is best to leave it to a professional with expertise with these systems.
Locksmiths can program keys quickly with onboard programming. It can take as little as an hour if everything is done correctly. If the key isn't in good working order or the procedure isn't followed exactly, the process can take as long as a half hour.
There are numerous key programmer scanners on the market that work with various vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they can be used with a variety of vehicle models. There is no system that can program every vehicle. Furthermore, these systems are expensive. It's a good idea purchase a computer that receives regular updates as the manufacturer releases new technologies.
