Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
Most US and Asian car manufacturers use the same programming protocols as auto tool manufacturers so that they can develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are small computer microchips which emit radio signals of low-level. The microchips are equipped with an unique serial number that authenticates your key when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been a huge success in preventing theft of cars. It has also saved many car owners a significant amount of money since they don't have to replace their vehicles.
The basic concept 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 would simply force your car's ignition switch into the "on" position using a flat screwdriver or even use hot wires to disable the system entirely. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it transmits the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. reprogram car key will then detect that the key is legitimate and allow fuel to flow, power up the starter, or even begin it.
Depending on the manufacturer, some vehicles will only recognise certain types of transponder chip. It is therefore important that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have an instrument for programming keys for multiple vehicles that works with different models and car brands. This is a less expensive solution than buying specific tools for each type of vehicle. There are also specialised automotive key programmer devices that are only suitable for specific brands of vehicles however, they are less frequently used. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you select a reputable firm that has this kind of equipment.
Key FOBs
As the name suggests, key FOBs house the programmable transponder chips that enable 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 fuel flap control. Certain fobs can be controlled with the press of buttons. For example an "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60 or a 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 in case yours stops functioning. This is because an expert locksmith has the specialized equipment and access to the programming tools needed to connect your car's computer to the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs are equipped with security features that make it more difficult for criminals to duplicate and copy the signals they transmit. Certain key fobs come with pseudo-random code generators which generate a new unlock code every time you press the button. This prevents attackers capturing and replaying the unlock signal to gain access to your car.
In most cases you can buy a replacement key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customers' keys.
Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, professional locksmiths strongly discourage using them as they're more likely to perform poorly or not at all. Instead, they recommend purchasing fobs specifically designed for your specific vehicle so that you can be certain they'll function properly and be less susceptible to issues like interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.
Toolkits for Programming Vehicles of Manufacturers
The automotive industry has advanced considerably and modern vehicles require computer technology in order to function. A transponder chip is an important part of this technology. It has to be programmed by a locksmith mechanic or dealer to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a movie) and the car won't start if it doesn't have the proper key.
These key fobs are a little more complex than the traditional mechanical key and are the reason you'll usually find them in the hands of an expert, professional auto locksmith. The cost of the car key fob is depending on the type and model of key, but it is typically between $85 to $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 computer onboard of the car. The software blocks access by unauthorised persons by only allowing keys that have been programmed for a specific vehicle to function. This means that if you need your keys replaced, you'll need have the new key fob programmed to the car for it to work.
This is accomplished by using a programming tool for car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. The key programming tool could be a handheld device that is inexpensive device or a more expensive one that can perform various things beyond key programming (like reading and cloning Eeprom files within the ECU).
While some may try to program their own keys with these tools, this is an activity best left to a professional auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's easy to make a mistake and alter settings that could damage the vehicle. The most important thing to keep in mind is that a skilled professional can assist you in avoiding these problems.
On-Board programming
If your car isn't as old that it has a key, it might still come with a key made of metal that can be used to open doors and turn off the ignition. However, modern vehicles have transponder chips that must be recognized by the computer system of the car to begin. This adds an extra layer of protection that can stop car thieves from starting a car stolen and driving off with it. A locksmith who is certified will have the right tools and software to program a new key that is compatible with your car's security system.
Your locksmith will first need to acquire a key blank that is that is compatible with the vehicle's make and model. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will put your car into the mode of programming that will allow the locksmith to add a new key to the system.
To do this, the key programmer scanner will communicate with the car's computer to send an exact code. The computer will recognize the code and add it to the list of approved keys. In some instances the scanner will be able to erase keys that have been stolen or lost from the system.
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. This is why it's best left to a professional that has extensive experience working with these kinds of systems.
Locksmiths can program keys quickly by using onboard programming. It takes as little as a minute when everything is executed correctly. However, if the key isn't in correct situation or the procedure is not adhered to, it could take up to an hour.
There are a variety of key programmer scanners available that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide selection of vehicle models. However, no system will be able to program every vehicle in existence. They are also expensive. It's a good idea purchase a programer that receives regular updates as the manufacturer develops new technologies. Your computer's programming software will soon become obsolete if you don't take this step.
