Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the car's maker and model, the process can be as easy as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers in order to create hardware and software for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio signals. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has been an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money as they do not have to purchase new cars.
The principle behind the transponder system is to make it difficult for thieves to start your car without the proper key. In the past, thieves would simply push your ignition switch to the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system altogether. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will recognize that the key is genuine and allow fuel to flow, power the starter or begin it.
Certain vehicles only recognize a specific type of transponder chip, depending on the manufacturer. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different models and manufacturers of cars. This is a more cost-effective solution than buying specific tools for each type of vehicle. There are also specific automotive key programmer devices that are only suitable for specific models of vehicles however, they are less popular. The best automotive locksmiths will have the right tools to work on any type of vehicle, so ensure you choose a reputable firm with these kinds of tools.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to unlock doors and start the engine using a push button ignition. They also have buttons you can press to activate features like trunk release, door locks or control of the fuel flap. Some fobs can be controlled using buttons. For instance, a "smart key" which allows you to summon your car to parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help of an instruction manual, however you will need to call an automotive locksmith in the event that yours isn't 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 OBD (OBD) port located beneath the steering wheel.
Today, most key fobs come with security features that make it difficult for hackers to clone or replicate the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some instances you can purchase the replacement keyfob at an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of the major US and Asian automobile manufacturers share their key fob programming protocols with third-party firms that make the tools that auto locksmiths utilize to programme keys for their customers.
Some aftermarket key fobs may be advertised as being compatible with all vehicles. However, professional locksmiths strongly discourage using them as they're likely to function poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have progressed a lot and today's vehicles need computers to function. One of the key components of this technology is a transponder chip that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to prevent hot-wiring, as in a film. The car won't start if the keys are not correct.
Key fobs are a little more complex than a conventional mechanical key. This is why they're usually handled by experienced professional auto locksmiths. The cost of a car key fob varies depending on the type and model of key, but it is generally between $85 to $400. This includes the labor to program the key fob and the costs for any required replacement parts.
To make the process more complicated, these car key fobs make use of a special software to connect to the car's onboard computer. The software blocks unauthorized access by only permitting the key to function if it has been programmed to that specific car. If you decide to replace your keys, you will have to program the new key fob into the car for it to work.
This is done by using a programing tool for car keys that is compatible with your vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter a programming mode. Key programming tools can be a handheld device that is inexpensive device or a high-end one that is capable of performing many things beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people attempt to program their keys by themselves using these tools. However this should be left to an experienced auto locksmith. It's easy to make a mistake with the software systems if you aren't aware of the nuances. This could result in damage. It's crucial to remember that a professional with experience will help you avoid these problems.
On-Board programming
If your car is of a certain age that you'll have a traditional metal key to use to unlock the doors and turn on the ignition. Modern vehicles have transponders that must be acknowledged and accepted by the computer system before it can start. This is a further layer of security to keep car thieves from starting and then driving off with a stolen car. A locksmith who is certified will have the tools and software necessary to program a key that can function in your car's system.
Your locksmith will first need to purchase a blank key that is compatible with the vehicle's model and make. Once the key is in hand the locksmith will connect the scanner that is used for programming to the diagnostic port of your car. This will put the vehicle into a specific programming mode, which allows the locksmiths to add keys to the system.
To do this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will be able program keys for cars to recognize the code and add it to the list of keys that are approved. In some instances, a scanner can also remove keys that have been stolen or lost.
You can also program new keys using EEPROM. It is more complex and requires a thorough understanding of electronic systems. It's best to leave it to a professional with knowledge of these systems.
Onboard programming is the quickest method for locksmiths to program the new key. If everything is done properly, it can take just one minute. If the key isn't in the correct condition or the procedure isn't followed exactly, the process could take up to half an hour.
There are many key programmer scanners that support different vehicle models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide selection of vehicle models. No system can program every vehicle. 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. Otherwise, your programming machine will be obsolete in a short time.
