Automotive Locksmith Key Programming
Most modern-day cars require some type of key programming. Depending on the model and make the procedure could be as simple as using an additional key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can design software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has been an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money because they don't have to buy new their cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to start your car without a key. In the past car thieves would use a flat screwdriver to force the ignition switch of your car to go into "on" mode or even wire it hot to bypass the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip within the key. The onboard computer of the car will recognize the key as valid and will allow fuel flow and power the starter to start the engine.
Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it is important to ensure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs properly.
A good automotive locksmith will have a multi-vehicle programming device which can be used on many different automobile models and manufacturers. This is a more cost-effective approach than purchasing separate tools for each type of vehicle. They are not as common but there are automotive key programmers that can only work on a specific type of vehicle. The best automotive locksmiths will have the appropriate tools to work on any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
The name implies that key FOBs contain transponder chips programmable that allow your car to recognize and unlock the doors, or start the engine with a push-button ignition. They also have buttons you can press to activate features like door locks, trunk release or control of the fuel flap. Some fobs can be controlled using buttons. For example the "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the assistance of the user guide, however you'll need to call an automotive locksmith if the one you have isn't working. This is because a professional locksmith has the right equipment and access to the tools for programming 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 clone and replicate the signals that they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy a replacement keyfob from an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your car. This is because most of the major US and Asian car makers share their key fob programming protocols with third-party companies who produce the tools locksmiths use to program their customers' keys.
While some aftermarket key fobs are advertised as compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them since they are likely to function poorly or not at all. Instead, they recommend purchasing fobs designed specifically for your specific vehicle so that you are certain they'll work properly and are less prone to issues such as interfering or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has made huge advancements in the past few decades. Today's cars are computer-driven. Transponder chips are an essential part of this technology. It must be programmed by a locksmith mechanic, or dealer to work. These key fobs have built-in security features that will prevent hot-wiring (like in a movie) and the car won't start without the proper key.
These key fobs can be a little more complex than a traditional mechanical key. This is why they are placed in the hands of experienced professional auto locksmiths. The cost of the car key fob can vary dependent on the model and type of key, but it is typically between $85 to $400. This includes the cost of labor to program the key fob as well as the costs for any necessary replacement parts.
To make the process more difficult to make the process more complicated, these key fobs for cars use a special software system to work with the car's onboard computer. The software prevents unauthorized access by permitting the key to function only if it's programmed to the car in question. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car in order to function.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. The key programming device could be an handheld device that is affordable or extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
While programming car key may attempt to program their own keys using these tools, this is an activity best left to a professional auto locksmith. It is easy to make mistakes when using software systems if you don't know the nuances. This can lead to damage. It's important to keep in mind that a professional with experience will help you avoid these problems.
On-Board Programming
If your car is old enough, it may still come with a key made of metal that can be used to open doors and turn off the ignition. Modern cars come with transponders that need to be acknowledged and accepted by the computer system in order to start. This is a further layer of security to keep car thieves from starting and driving away with a stolen car. A certified locksmith will have the right tools and software to program a new key that will work with the security system of your vehicle.
The locksmith will require an uncut key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will put the vehicle into the mode of programming 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 and send a specific code. The computer will detect 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.
You can also program new keys using the EEPROM. It is more complex and requires an in-depth understanding of how electronic systems work. It's best to leave it to a professional with knowledge of these systems.
Locksmiths can program keys quickly with onboard programming. It can take less than an hour if everything is completed correctly. However, if the key isn't in correct state or the procedure isn't strictly followed, it could take as long as a half hour.
There are a variety of key programmer scanners that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their wide selection of vehicle models. However, neither can be programmed for every single vehicle that exists. These machines are also quite expensive. It is a good idea to purchase a computer that is updated regularly as the manufacturer develops new technologies. Your programming machine will quickly become obsolete if you don't take this step.
