Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on your vehicle's model and make, the process may be as simple as using an additional key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent 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, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money by not having to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past car thieves would use the flat screwdriver to push the ignition switch in your car to go into "on" mode or even hot-wire it to bypass the system. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then recognize that the key is legitimate and allow fuel to flow, turn the starter or start it.
Some vehicles only recognize a specific type of transponder chip according to the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs correctly.
A reliable locksmith for cars will have a multi-vehicle programming device which can be used on many different car models and manufacturers. This is a far cheaper option than buying separate tools for each type of vehicle. There are also specially-designed automotive key programmer devices that can only be used on specific brands of vehicles, but these are less frequently used. The top automotive locksmiths have the proper tools to work on any type of vehicle, so make sure you choose a reputable business with these kinds of tools.
Key FOBs
As the name implies, key FOBs contain transponder chips that can be programmed to allow your car to recognize and unlock the doors or start the engine with a push-button ignition. They also have buttons that you can push to activate features such as trunk release, door locks or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For instance, a "smart key" that lets you call your car to parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program replacement key fobs yourself using the help of an instruction manual, however you'll need to contact an automotive locksmith in the event that yours isn't working. A professional is better equipped to connect your computer to the vehicle to the OBD port on the steering wheel.
The majority of key fobs today have security features that make it difficult for attackers 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 prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.
In many instances you can buy an additional key fob at the dealer or from another retailer and have it programmable by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party companies who make the tools used by auto locksmiths to program their customer's keys.
Certain key fobs from the aftermarket may be marketed as being compatible with all vehicles. However, locksmiths for automotive strongly discourage using them as they are likely to work poorly or not work even work at all. They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have progressed a lot, and today's vehicles require computer technology in order to function. One key element of this technology is a transponder chipset that requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to function. Key fobs are fitted with security features to prevent hot-wiring, like in a film. The car will not start if the keys are not correct.
Key fobs are a bit more complex than the mechanical keys and that's why you'll typically find them in the hands of an expert professional auto locksmith. The cost of the car key fob can vary depending on the model and type of key, but it is generally between $85 and $400. This includes the labor required to program the key fob and the cost of any needed replacement parts.
Car key fobs are more complicated because they use software that interacts with the onboard computer of the car. The software prevents unauthorised access by only permitting keys that have been programmed for a specific car to read more function. If you change your keys, you'll need to program the new key fob in the car for it to work.
This is accomplished using a programming tool for keys for cars that are compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter programming mode. The key programming device could be an handheld device that is affordable or extravagant and can do more than just programming keys (like reading the eeprom files in the ECU).
While some may try to program their own keys using these tools, it's an activity best left to an experienced auto locksmith. Unless you're familiar with all the details of the various software systems, it's possible to accidentally change settings that could cause damage to the vehicle. It's crucial to remember that an experienced professional will help you avoid these problems.
On-Board programming
If your car is older than it could still be equipped with a metal key that you can use to unlock doors and turn off the ignition. Modern cars are equipped with transponder chips that must be recognized by the computer system of the car in order to start. This is an additional layer of security that stops car thieves from stealing a car and driving off with the car. A licensed locksmith will have the necessary tools and software to create a new key that is compatible with your car's security system.
Your locksmith will have to obtain a blank key that is compatible with your car's make and model. Once the key is in your possession the locksmith will connect the scanner for programming to the diagnostic port of your car. This will put your car in a special programming mode, which will allow locksmiths to add the key to the system.
To do this, the key programmer scanner will communicate with the car's computer system to transmit a specific code. The computer will recognize the code and add it to the list of keys that are authorized. In some cases the scanner will be able to erase keys that have been stolen or lost from the system.
You can also program new keys using EEPROM. It is more complicated and requires a thorough understanding of electronic systems. It is best to delegate it to a professional who has experience with these systems.
Locksmiths can program keys quickly with onboard programming. If everything is done correctly it could take just one minute. However, if the key isn't in right state or the procedure isn't adhered to, it could take as long as a half hour.
There are a variety of key programmer scanners available that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide range of vehicle models. However, no system will be able to program every single vehicle that exists. They are also expensive. It's a good idea purchase a programer that receives regular updates when the manufacturer introduces new technologies. In the event that your machine is not updated, it will be obsolete in a short time.
