Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool makers in order to create software and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use transponder chips to stop car theft. These are tiny computer microchips which emit low-level radio waves. The microchips are equipped with a unique serial number which authenticates your key when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an enormous success in preventing auto theft. It also saves many car owners a significant amount of money as they don't have to buy new their cars.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car to go into "on" mode, or hot-wire it to evade the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key in the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The onboard computer of the car will then recognise the key as valid and allow fuel flow and start the starter. begin the engine.
Some vehicles only recognize certain type of transponder chip, depending on the manufacturer. It is therefore essential that your locksmith in the automotive industry is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that is compatible with different models and car brands. This is a less expensive solution than buying separate tools for each brand of vehicle. These aren't as popular but there are automotive key programmers that are able to only work on a specific model of vehicle. The best locksmiths for automotive are equipped to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
As the name suggests, key FOBs house the transponder chips programmable that allow your vehicle to identify and unlock the doors, or start the engine using push-button ignition. You can also press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled with the press of buttons. For instance an "smart key" which allows you to summon your car to parking spaces, such as a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help of an instruction manual, however you'll need to call an automotive locksmith if the one you have isn't working. This is because an expert locksmith has the right equipment and access to the programming tools required to connect your car's computer to the OBD (OBD) port that is located under the steering wheel.
car key programming of key fobs today include 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 which 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 vehicle.
In certain instances you can purchase a replacement keyfob from an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that produce the tools used by auto locksmiths to program their customer's keys.
While some aftermarket key fobs are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them as they will likely only work poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle so that you are certain they'll function correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Tool for programming the vehicle manufacturers
Automotive technology has come a long way and modern vehicles require computers to function. A transponder chip is an essential component of this technology. It needs to be programmed by a locksmith mechanic or dealer to function. These key fobs have built-in security features that will prevent hot-wiring (like in a movie) and the car won't start without the proper key.
These key fobs are a little more complex than the traditional mechanical key, which is why you'll usually find them in the hands of an expert, professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the type of key, but they typically run between $85 and $400. This includes the cost of labor to program the key fob, as well as the costs for any required replacement parts.
To make the process more difficult, these car key fobs use a special software system to connect to 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 replace your keys, you'll need to program the new key fob into the car for it to function.

The most common method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. 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 extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
Some people may attempt to program their keys on their own using these tools. However it's best to leave this task to a professional auto locksmith. It's easy to make mistakes with the software systems if you don't understand the nuances. This could lead to damage. The most important thing to remember is that an experienced professional can help you avoid these issues.
On-Board programming
If your vehicle is old enough that you'll have a key from the past that you can use to open the doors and turn off the ignition. However, modern vehicles come with a transponder chip that must be recognized by the computer system of the car to allow it to start. This adds another layer of security that prevents car thieves from starting and then driving off with a stolen vehicle. A locksmith certified will have the tools and software necessary to program a key that will be compatible with your car's security system.
The locksmith will require a blank key that is compatible with the make and model of your vehicle. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will place the car into an exclusive programming mode that will allow the locksmith to add a new key into the system.
To accomplish this, the key programming scanner will communicate with the car's computer system to transmit a specific code. The computer will be able to recognize this code and add it into the list of keys that are approved. In certain instances, the scanner will also be able to remove lost or stolen keys from the system.
You can also program new keys using EEPROM. 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.
Onboard programming is the most efficient way for a locksmith to program the new key. It takes as little as one minute if everything is executed correctly. If the key is not in the right condition or the procedure isn't followed exactly, the process can take as long as a half hour.
There are numerous key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide range of vehicle models. However, neither can be programmed for every vehicle in existence. These devices are also expensive. It's best to purchase one that will receive regular updates from the manufacturer whenever new technologies are developed. Otherwise, your programming machine will be obsolete in a short time.
