Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process could be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car makers have programming protocols that they share with auto tool makers so that they can develop software and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be a huge 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 vehicles.
The principle 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 push your ignition switch to the "on" position using the flat screwdriver, or hot-wire the car to bypass the system entirely. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder key in the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip inside the key. The computer onboard of the car will then recognize the key as valid and allow fuel flow, power the starter or start the engine.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. It is therefore important that your locksmith in the automotive industry is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will possess a multi-vehicle programing device which can be used on many different models and brands of cars. This is a more cost-effective approach than purchasing separate tools for each type of vehicle. They are not as common, but there are specialised automotive key programmers that are able to only work on a particular brand of vehicle. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so be sure you choose a reputable business with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chips that allow your vehicle to unlock doors and start the engine with the push of a button ignition. There are also buttons that you can push to activate features like trunk release, door locks or fuel flap control. Certain fobs can be controlled by pressing buttons. For example, a "smart key" that allows you summon your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the help of a user manual but you'll usually require an automotive locksmith to have a new one programmed if yours stops functioning. This is because a professional has the equipment that is specialized and access to the tools for programming needed to connect your car's computer through 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 clone and replicate 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 from capturing and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy a replacement keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who produce the tools used by locksmiths who program their customers' keys.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them since they're likely to work poorly or not at all. Instead, they suggest buying fobs that are specifically made for your vehicle so that you are certain they'll function properly and be less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technology has come a long way and modern vehicles require computer technology in order to function. One key element of this technology is a transponder chip which must be programmed into the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs with embedded security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the proper key.
Key fobs can be slightly more complicated than a conventional mechanical key. This is why they are handled by experienced, professional auto locksmiths. The cost of the car key fob can vary dependent on the model and type of key, but it is generally between $85 and $400. This includes the cost of labor to program the key fob and the costs for any necessary replacement parts.
Car key fobs are more complex due to the fact that they use a software system that works with the onboard computer of the car. The software blocks unauthorized access by only permitting the key to function only if it's programmed for the specific car. If you change your keys, you will have to program the new key fob in the car in order for it to function.
This is done by using a programing tool for car keys that is compatible with the vehicle's brand. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. Key programming tools can be a simple handheld device or a fancy one that can do a wide range of things beyond just key programming (like reading and cloning the eeprom files in the ECU).
While some may try to program their own keys using these tools, it's a job best left to an experienced auto locksmith. If you're not aware of all the aspects of the various software systems, it's very easy to make a mistake and alter settings that could damage the vehicle. It's important to remember that a knowledgeable professional can assist you in avoiding these issues.
On-Board Programming
If your vehicle is of a certain age, you'll still have a traditional metal key to open the doors and turn over the ignition. Modern cars come with a transponder that must be acknowledged and accepted by the computer system to start. This is an additional layer of security to keep car thieves from starting and then driving off with a stolen vehicle. A licensed locksmith has the tools and software to create a key that will work 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 your locksmith has the key, he'll connect the scanner for programming to the diagnostic read more port of your vehicle. This will put your car into a special programming mode that allows the locksmith to add a new key into the system.
The key programmer scanner communicates with the computer in the car to send the 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 remove lost or stolen keys 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 how electronic systems work. This is why it's best left to a professional that has a lot of expertise working on these types of systems.
Locksmiths can program a key quickly by using onboard programming. When everything is done correctly it can take as little as one minute. If the key is not in the right condition or the procedure isn't followed precisely, the procedure could take as long as a half hour.
There are a variety of key programmer scanners that support different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they can be used with a variety of automobile models. No system can program every vehicle. In addition, these machines cost a lot. It is a good idea to purchase a computer that will get regular updates when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you don't take this step.
