Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the model and manufacturer the procedure could be as simple as using an extra key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers share their programming protocol with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio signals. The microchips are equipped with a unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proven to be an immense success in stopping auto theft. It also saves many car owners a significant amount of money as they don't need to replace their cars.
The principle behind the transponder system is to make it impossible for thieves to start your car without a key. In the past, thieves would simply force your ignition switch to the "on" position using the flat screwdriver, or hot-wire the car to bypass the system entirely. These kinds of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert a transponder keys 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 to match the frequency of the chip within the key. The onboard computer of the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Some vehicles only recognize certain type of transponder chip depending on the manufacturer. It is therefore important that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that can work on many different car manufacturers and models. This is a more cost-effective alternative to 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 type of vehicle. The top automotive locksmiths have the tools to work on any vehicle. Make sure you select an established company that has this type of equipment.
Key FOBs
As the name implies, key FOBs are home to 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. You can also use the buttons to trigger features such as door locks, trunk releases or controls for the fuel flap. Certain fobs can be controlled using buttons. For example, a "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the assistance of an instruction manual, however you will need to call an automotive locksmith in the event that yours isn't functioning. This is because an expert locksmith has the right equipment and access to the programming tools required to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to replicate and clone the signals they transmit. They include pseudo-random generators that generate a fresh unlock code every time you press the key fob's button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your car.
In many instances you can purchase an alternative key fob from the dealer or from another retailer and then have it programmed by your automotive locksmith to fit your particular vehicle. This is because most of the major US and Asian car makers use key fob programming protocols with third-party firms that produce the tools locksmiths for auto utilize to program their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them because they are likely to function poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing your fobs.

The cost of the car key fob can vary depending on the model and type of key, but it is typically 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 make the process more complicated, these car key fobs make use of a special software to work with the car's onboard computer. The software prevents unauthorized access by only allowing the key to operate only if it's programmed for the specific car. If you decide to replace your keys, you'll need to program the new key fob to the car in order for it to work.
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 allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. The key programming device can be a handheld device that's inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom file inside the ECU).

The computer will be able to recognize the code and add it to the list of keys approved by. In some cases the scanner will be able to remove keys that are 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 a thorough understanding of how electronic systems operate. It is best to leave it to a professional with experience with these systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. It can take less than a minute when everything is completed correctly. However, if the key isn't placed in the right situation or the procedure isn't followed exactly, it can take up to an hour.
There are reprogram car key that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their broad range of vehicle models. There is no system that can program every vehicle. These machines are also quite expensive. It's best to purchase one that will receive regular updates from the manufacturer as new technologies are introduced. Your programming machine will quickly become obsolete if you don't do this.
