Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can design tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are tiny computer microchips which emit low-level radio waves. They have an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has been extremely successful in preventing car theft. This technology has also helped car owners save a huge amount of money since they don't have to replace their vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, car thieves would force your car's ignition switch into the "on" position with an ordinary screwdriver or use hot wires to disable the system completely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert the transponder keys into the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The onboard computer in the car will then recognize the key as being valid and will allow fuel flow, power the starter or start the engine.
Depending on the manufacturer some vehicles will only recognise the specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will have a multi-vehicle programming device that can be used on a variety of different models and brands of cars. This is a less expensive option than purchasing individual tools for every brand of vehicle. These are less common but there are automotive key programmers that are able to only work on a particular type of vehicle. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so be sure you find a reputable company with these kinds of tools.
Key FOBs
As the name implies, key FOBs are home to the transponder chips that can be programmed to allow your vehicle to identify and unlock the doors, or start the engine using a push button ignition. They also have buttons that you can press to activate features such as door locks, trunk release or control of the fuel flap. Some fobs also have additional functions that can be controlled using the push of a button like a "smart" key fob that allows you to summon your car into tight parking spots as you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith if yours has stopped working. A professional is better equipped to connect your computer to the vehicle via the OBD port located under the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to duplicate and copy the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code each time you press the button. This stops attackers from recording and playing back the unlock signal in order to reprogramming keys for cars gain access to your car.
In most instances you can buy a replacement key fob from the dealership or another retailer and have it programmed by your automotive locksmith to work with your particular vehicle. This is due to the fact that most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party firms that produce the tools auto locksmiths employ to programme keys for their customers.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles, most automotive locksmiths do not recommend using them since they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has made great advances in the last couple of decades. Today's vehicles are computer-driven. One key element of this technology is a transponder chip which requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. These key fobs are equipped with security features that prevent hot-wiring like in a film. The car will not start without the correct keys.
Key fobs can be somewhat more complicated than a standard mechanical key. This is why they are placed in the hands of experienced, professional auto locksmiths. The cost of a key fob can differ based on the vehicle model and the type of key, but they typically run between $85 to $400. This includes the labor cost to program the keyfob and any replacement parts.
The car key fobs are more complicated because they use a software system that works with the onboard computer of the car. The software blocks access to unauthorized users by allowing the key to operate if it has been programmed to the car in question. This means that if you need your keys replaced, you'll need to have the new key fob programmed to the car for it to function.
This is accomplished using a tool for programming car keys that is compatible with the vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming tool could be a handheld device that is inexpensive device or a fancy one that can do many things beyond just key programming (like reading and cloning the Eeprom files within the ECU).
Some people may try to program their keys by themselves using these tools. However this should be left to a professional auto locksmith. It's easy to make mistakes with the software systems if you aren't aware of the nuances. This could lead to damage. It's important to keep in mind that a knowledgeable professional can help you avoid these problems.
On-Board Programming
If your car is older than that it has a key, it might still come with a key made of metal that you can use to open doors and turn the ignition. Modern vehicles have transponders that must be recognized and accepted by the computer system to start. This adds another security measure to prevent thieves from stealing the car and then driving off with a stolen vehicle. A locksmith who is certified will have the necessary tools and software to create a key that works with the security system in your car.
First, your locksmith will require an uncut key that is compatible with the make and model of your vehicle. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put your car into a special programing mode, which will allow locksmiths to connect keys to the system.
The key scanner is programmed to communicate with the computer of the car to send an electronic code. The computer will be able to recognize this code and include it into the list of approved key. In certain situations the scanner will also delete lost or stolen keys.
You can also program new keys with the EEPROM. It is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional who has experience with these systems.
Onboard programming is the most efficient method for locksmiths to program the new key. It takes as little as an hour if everything is executed correctly. If the key isn't in the proper situation or the procedure isn't strictly followed, it could take up to an hour.
There are many key programmer scanners on the market that can be used with different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they cover a wide range of vehicle models. No system can program every vehicle. In addition, these machines cost a lot. It is recommended to purchase one that will receive regular updates from the manufacturer whenever new technologies are released. In the event that your machine is not updated, it will become obsolete quickly.
