Automotive Locksmith Key Programming
Modern cars need some type of key programming. Depending on your vehicle's model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers use the same programming protocols as auto tool makers, so they can create software or hardware for locksmiths in the automotive industry.

Transponder chips are found in a variety of newer vehicles to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. They have an unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proven to be an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money as they do not have to replace their vehicles.
The transponder system's basic idea is to make it hard for thieves to get into your vehicle without the correct key. In the past, car thieves would simply force the ignition switch of your car into the "on" position with a flat screwdriver or even make use of hot-wires 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 an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's onboard computer will then recognise that the key is valid and allow fuel to flow, turn up the starter or begin it.
Based on the manufacturer, certain vehicles can only accept certain types of transponder chip. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming tool that is compatible with different models and manufacturers of cars. This is a less expensive solution than buying individual tools for every brand of vehicle. These are less common but there are automotive key programming tools that can only be used on a specific model of vehicle. The best automotive locksmiths will have the proper tools to deal with any kind of vehicle, so ensure you choose a reputable firm with these kinds of tools.
Key FOBs
The name implies that key FOBs house the transponder chips programmable that enable your car to recognize and unlock the doors, or start the engine with a push-button ignition. You can also use the buttons to activate features like door locks, trunk releases or fuel flap controls. Some fobs have additional functions that can be controlled with the button presses like the "smart" key fob that allows you to bring your car into tight parking spots, like you would with a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the aid of a user's guide, you'll often require an automotive locksmith to get a new one programmed if yours stops working. This is because an expert locksmith has the right equipment and access to the tools for programming needed to connect your car's computer to the OBD (OBD) port beneath the steering wheel.
The majority of key fobs are equipped with security features that make it difficult for attackers to clone and replicate the signals that they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy an additional key fob at the dealer or other retailer and have it programmed by a locksmith for your vehicle to be compatible with your particular vehicle. This is because the majority of the major US and Asian automobile manufacturers use key fob programming protocols with third-party firms that create the tools locksmiths use to program keys for their customers.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles, most automotive locksmiths do not recommend using them since they're likely to work poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your vehicle, so that you can be certain they'll function properly and be less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.
Tool for Programming Vehicle Manufacturers'
The automotive industry has progressed a lot, and today's vehicles require computers to function. One of the key components of this technology is a transponder chip which needs to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to work. Key fobs come with built-in security features that stop hot-wiring (like in a film) and the car will not start if you don't have the right key.
Key fobs are more complicated than a mechanical keys, which is 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 type of key, but they typically run between $85 and $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.
Car key fobs are more intricate because they utilize software that interacts with the computer onboard of the car. The software prevents unauthorised access by only allowing keys programmed for a specific car to work. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car for it to work.
This is done by using a programming tool for keys for cars that are compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming devices can be an handheld device that is inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, it's an activity best left to a professional auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's easy to accidentally alter settings that could potentially damage the vehicle. It's crucial to remember that a professional with experience will help you avoid these problems.
On-Board programming
If your car is old enough that you'll have a traditional metal key to open the doors and turn on the ignition. Modern cars have transponder chips that must be recognized by the car's computer system to begin. This is a further layer of security to keep thieves from starting and driving away with a stolen car. A locksmith who is certified will have the tools and software required to create a key that will work in your car's system.
First, your locksmith will need to get an uncut 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 put your vehicle into a specific programming mode, which allows locksmiths to add a key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to transmit the code. The computer will recognize this code and add it to the list of keys that are authorized. In certain situations the scanner will also delete lost or stolen keys.
Programming EEPROM is another method 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. If everything is done properly it can take as little as one minute. However, if the key isn't in correct state or the procedure isn't followed exactly, it can take as long as a half hour.
There are many different key programmer scanners that support different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their wide range of models for vehicles. However, no system can be programmed for every vehicle in existence. In addition, these machines are quite expensive. It is recommended to purchase a programmer which will receive regular updates from the manufacturer whenever new technologies are released. Your computer's programming software will soon become obsolete if you don't take this step.
