Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the vehicle's make and model, the procedure can be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car makers use the same programming protocols as auto tool makers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are microchips in the form of computers which emit radio signals of low-level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a good amount of money since they don't have to buy new vehicles.
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 use a flat screwdriver to force the ignition switch of your car into the "on" mode, or hot-wire it in order to bypass the system. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you place the transponder key into the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will detect that the key is valid and allow fuel to flow, power the starter or begin it.
Depending on the manufacturer certain vehicles can only accept certain types of transponder chip. This is why it's important to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs correctly.
A good automotive locksmith will utilize a multi-vehicle programmable tool that can be used on a variety of different models and brands of cars. This is a cheaper option than buying specific tools for each model of vehicle. There are also specific automotive key programmer devices that are only suitable for specific brands of vehicles however, they are less popular. The most reliable automotive locksmiths will have the proper equipment to tackle any type of vehicle, so make sure you find a reputable company that offers these types of tools.
Key FOBs
The name implies that key FOBs contain programmable transponder chips that allow your vehicle to recognize and open the doors, or start the engine using a push button ignition. You can also press buttons to trigger features such as trunk locks, door locks or controls for the fuel flap. Certain fobs come with additional functions that can be controlled using the push of a button for example, a "smart" key fob that lets you bring your car into parking spaces that are difficult to access, like you would with the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you using the aid of a user's guide however, you'll typically require an auto locksmith to get a new one programmed if the one you have isn't functioning. A professional locksmith is better equipped to connect the computer of your car via the OBD port on the steering wheel.
Today, most key fobs include security features that make it difficult for criminals to clone or replicate 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 many instances, you can purchase an additional key fob at the dealership or another retailer and then have it programmed by your locksmith in your car to fit 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 customers' keys.
Some aftermarket key fobs may be marketed as compatible with any vehicle. However, automotive locksmiths strongly discourage using them as they're more likely to perform poorly or even not even work 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 like interfering or not working. This will save you money over the long term by avoiding expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has come a long way and modern vehicles require computers 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 proper key.
Key fobs are somewhat more complicated than a traditional mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob will vary based on the vehicle model and the key type however they usually cost between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more difficult the car key fobs make use of a special software to work with the car's onboard computer. The software blocks access by unauthorised persons by only permitting keys that have been programmed for a specific vehicle to function. This means that if you get your keys replaced, you'll need to have the new key fob programmed to the car in order for it to work.
This is accomplished using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool permits a locksmith to connect to the OBD port on the vehicle and then enter the programming mode. The key programming tool could be a simple handheld device or a more expensive one that can here do various things beyond just key programming (like reading and cloning EEEPROM files in the ECU).
Although some people might attempt to program their own keys with these tools, it's an activity best left to an experienced auto locksmith. It's easy to make a mistake with the software systems if you don't know the intricacies. This could lead to damage. It's crucial to remember that a knowledgeable professional can help you avoid these problems.
On-Board Programming
If your vehicle is old enough to be considered old-fashioned, you'll have a key from the past to open the doors and turn off the ignition. However, modern cars are equipped with transponder chips that need to be recognized by the car's computer system to allow it to start. This is an extra layer of security that prevents 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 key that will work with your car's security system.
First, your locksmith will need to get a blank key that is compatible with the model and make of your car. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will place the car into a special programming mode that will allow the locksmith to add a new key to the system.
To do this, the key programming scanner will communicate with the car's computer system to transmit an exact code. The computer will recognize the code and add it to the list of approved keys. In some instances the scanner may also be able to erase keys that have been 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 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 using onboard programming. If everything is done properly, it can take just one minute. If the key is not in good working order or the procedure isn't followed exactly, the process can take up to half an hour.
There are a variety of key programmer scanners that can be used with different vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they cover a wide range of automobile models. The system cannot program every vehicle. In addition, these machines are quite expensive. It is best to buy an instrument that receives regular updates from the manufacturer whenever new technologies are introduced. In the event that your machine is not updated, it will be obsolete in a short time.
