Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool makers to allow them to develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use transponder chips to stop car theft. These are tiny computer microchips which emit radio signals of low-level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal it will shut down. This technology has been a huge success in preventing theft of cars. This technology has also helped car owners save a good deal of money as they do not have to buy new vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, car thieves used a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode or even hot-wire it in order to bypass the system. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip inside the key. The car's onboard computer will recognise that the key is valid and allow fuel to flow, turn the starter or start it.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will have a multi-vehicle programming tool that can be used on many different car models and manufacturers. This is a more cost-effective solution than buying specific tools for each type of vehicle. These aren't as popular however, there are specialist automotive key programmers that can only work on a specific type of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this type of equipment.
Key FOBs
As the name suggests, key FOBs house the transponder chips that can be programmed to allow your vehicle to recognize and open the doors, or start the engine using a push button ignition. There are also buttons that you can press to trigger features like trunk release, door locks or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For instance an "smart key" that lets you call your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed with the help of a user manual however, you'll typically require an auto locksmith to get a brand new one programmed if the one you have isn't functioning. A professional locksmith is more equipped to connect your computer to the vehicle via the OBD port under the steering wheel.
The majority of key fobs come with security features that make it difficult for attackers to clone and replicate the signals they transmit. They include pseudo-random sequence 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 some cases you can purchase the replacement keyfob at an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who create the tools used by locksmiths who program their customers' keys.
Certain key fobs from the aftermarket may be marketed as being compatible with vehicles of all kinds. However, professional locksmiths strongly discourage using them as they're likely to function poorly or even not even work at all. Instead, they suggest buying fobs that are specifically made for your vehicle so that you are certain they'll work properly and are less susceptible to issues such as interfering or not working. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technology has come a long way, and today's vehicles require computer technology to function. A transponder chip is an important part of this technology. It needs to be programmed by a locksmith, mechanic, or dealer 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 correct key.
Key fobs are a little more complex than a standard mechanical key. This is why they're usually in the hands of seasoned, professional auto locksmiths. The cost of a key fob will vary based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the keyfob and any replacement parts.
The car key fobs are more intricate because they use an operating system that communicates with the onboard computer of the car. The software prevents unauthorized access by permitting the key to function if it has been programmed to the car in question. If you change your keys, you will need to program the new key fob in the car to allow it to function.
This is done by 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 tool can be a handheld device that is inexpensive device or a fancy one that can do many things beyond just key programming (like reading and cloning the eeprom files in the ECU).
While some people may attempt to program their own keys using these tools, it's something best left to an experienced auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to make a mistake and alter settings that could potentially damage the vehicle. It's crucial to remember that a professional with experience will assist you in avoiding these issues.
On-Board Programming
If your vehicle is older than you that you'll have a traditional key made of metal to use to unlock the doors and turn over the ignition.

This is an additional layer of protection that can stop car thieves from starting a car stolen and driving off with the car. A certified locksmith will have the right tools and software to create a new key that will work with your car's security system.

Once your locksmith has the key, he more info will connect the scanner for programming to the diagnostic port of your vehicle. This will put your vehicle into a specific programming mode, which will allow locksmiths to connect the key to the system.
The key programmer scanner communicates with the computer of the vehicle to send a code. The computer will recognize the code and add it to the list of keys approved by. In some cases, the scanner will also be able to remove keys that are stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complex and requires a thorough understanding of how electronic systems work. 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. When everything is done correctly, it can take just one minute. However, if the key isn't placed in the proper condition or the procedure is not strictly followed, it could take up to an hour.
There are a variety of key programmer scanners available that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they cover a wide range of vehicle models. No system can program every vehicle. They are also expensive. It is best to buy one that will receive regular updates from the manufacturer as new technologies are introduced. Otherwise, your programming machine will soon become obsolete.
