Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most 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 newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio signals. The microchips have an unique serial number that authenticates your key when you insert 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 car theft. It has also saved many car owners a significant amount of money because they don't have to buy new their cars.
The principle behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past, car thieves would force the ignition switch of your car into the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system completely. Transponder chips have drastically reduced the number of thefts.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will then recognise the key as valid and will allow fuel flow and power the starter to start the engine.
Depending on the manufacturer, some vehicles will only recognise certain types of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your car's keys and remotes.
A good automotive locksmith will have a multi-vehicle programming device which can be used on many different models and brands of cars. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. They are not as common, but there are specialised automotive key programmers that can only work on a particular brand of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reputable firm that has this type of equipment.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine using the push of a button. There are also buttons that you can press to trigger features like door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled by the press of a button like a "smart" key fob that lets you get your car into parking spaces that are difficult to access similar to a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help from the user guide, however you'll need to contact an automotive locksmith in the event that yours has stopped functioning. A professional is better equipped to connect your computer to the car via the OBD port located under the steering wheel.
The majority of key fobs are equipped with security features that make it harder for attackers duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a different unlock code every time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In many cases you can purchase an additional key fob at the dealer or from another retailer and have it programmable by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian automakers share their key-fob programming protocols with third-party companies that produce the tools used by locksmiths who program their customer's keys.
While some aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them as they will likely only work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they work correctly and are less prone to issues like 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
The automotive industry has made great advancements in the past few decades. Nowadays, cars are computer-driven. Transponder chips are an essential part of this technology. It has to be programmed by a locksmith, mechanic or dealer to function. Key fobs with embedded security features that stop hot-wiring (like in a movie) and the car will not start if you don't have the proper key.
These key fobs are a bit more complex than the traditional mechanical keys, which is why they are usually in the hands of a skilled professional auto locksmith. The cost of a key fob may 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 and the costs for any required replacement parts.
These car key fobs are more complex due to the fact that they use a software system that works with the computer onboard of the car. The software prevents unauthorised access by only permitting keys that have been programmed for a specific car to work. If you replace your keys, you'll have to program the new key fob in the car to allow it to function.
This is accomplished by using a tool for programming car keys that is compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming device can be a handheld device that is cheap or sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).
Although some people might attempt to program their own keys with these tools, this is an activity best left to a professional auto locksmith. It is easy to make mistakes here when using software systems if you don't know the nuances. This could result in damage. The most important thing to keep in mind is that an experienced professional can help you avoid these problems.
On-Board programming
If your car is old enough that it has a key, it might still come with a key made of metal that can be used to open doors and turn on the ignition. However, modern cars come with transponder chips that need to be recognized by the car's computer system to begin. This adds another layer of security that prevents thieves from stealing the car and then driving off with a stolen vehicle. A locksmith who is certified will have the tools and software needed to program a key that can be compatible with your car's security system.
Your locksmith will first need to purchase an uncut key that is that is compatible with your car's make and model. Once the key is in hand the locksmith will connect the scanner that is used for programming to the diagnostic port of your car. This will place the car into an exclusive programming mode that will allow the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to send an electronic code. The computer will be able to recognize this code and add it to the list of keys that are approved. In certain instances the scanner will be able to delete keys that are stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional who has a lot of expertise working on these types of systems.
Locksmiths can program a key quickly with onboard programming. If everything is done properly, it can take as little as one minute. If the key is not in good working order or the procedure isn't followed precisely, the procedure could be as long as half an hour.
There are many different key programmer scanners that can be used with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they support a broad range of vehicles. No system can program every vehicle. They are also expensive. It's best to purchase one that will receive regular updates from the manufacturer whenever new technologies are introduced. Otherwise, your programming machine will become obsolete quickly.
