Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer, or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers have a programming protocol that they share with auto tool makers, so they can create tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in many newer cars 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 vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money as they do not have to purchase new cars.
The principle of the transponder system is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, thieves would simply force your ignition switch to the "on" position using the flat screwdriver, or make use of hot-wires to bypass the system entirely. Transponder chips have drastically reduced these types of thefts.
When you insert the transponder key in the ignition, the signal is received by an antenna that is concealed around the barrel. The antenna is programmed with the 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.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs correctly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that is compatible with different models and manufacturers of cars. This is a cheaper option than buying specific tools for each model of vehicle. There are also specially-designed key programming devices for automotive that are only suitable for specific brands of vehicles however, they are less common. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you select a reputable firm that has this type of equipment.
Key FOBs
As the name suggests, key FOBs are home to the transponder chips that can be programmed to enable your vehicle to identify and unlock the doors, or start the engine with a push-button ignition. It is also possible to press buttons to activate features such as door locks, trunk releases or control of the fuel flap. Certain fobs can be controlled using buttons. For example, a "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual but you'll usually need an automotive locksmith to have a new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your vehicle via the OBD port located under the steering wheel.
Today, most key fobs include security features that make it difficult for hackers to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on the key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most cases, you can purchase a replacement key fob from the dealership or another retailer and have it programmed by your locksmith in your car to work with your specific vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that make the tools used by locksmiths for programming their customers' keys.
Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, locksmiths for automotive advise against using them since they are likely to work poorly or not even work at all. They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less susceptible 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
The automobile industry has made significant advances in the last couple of decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chipset that needs to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs come with security features that prevent hot-wiring, like in a movie. The car won't start without the correct keys.
Key fobs can be a little more complex than a standard mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob will differ based on the vehicle model and the key type however, they generally cost between $85 and $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more complicated the car key fobs make use of a special software to communicate with the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys that have been programmed specifically for a particular car to function. If you decide to replace your keys, you will have to program the new key fob in the car for it to work.
This is done by using a programing tool for keys for cars that are compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming device could be a handheld device that's affordable or extravagant and can do more than just program keys (like reading the eeprom file in the ECU).
Some people try to program their keys by themselves using these tools. However, reprogram car key is best left to an expert auto locksmith. It's easy to make mistakes with the software systems if you don't understand the nuances. This can 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 vehicle is of a certain age, you'll still have a traditional key made of metal to open 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 an additional layer of security to keep car thieves from starting and driving away with a stolen vehicle. A certified locksmith has the tools and software to program a new key that is compatible with the security system of your vehicle.
Your locksmith will need to obtain a key blank that is compatible with your vehicle's model and make. Once the key is received, your locksmith will link the programming scanner to the diagnostic port of your car. This will put the vehicle into an exclusive programming mode that allows the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to send an electronic code. The computer will recognize the code and add it into the list of keys that are approved. In some cases, the scanner will also be able to remove 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 complex and requires a deep understanding of electronic systems. This is why it should be left to a professional who has extensive experience working on these types of systems.
Locksmiths can program keys quickly using onboard programming. It can take less than an hour if everything is completed correctly. However, if the key isn't placed in the proper condition or the procedure isn't adhered to, it could take up to an hour.
There are numerous key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their broad range of vehicle models. However, neither can program every vehicle in existence. Additionally, these devices cost a lot. It is best to buy a programmer which will receive regular updates from the manufacturer when new technologies are released. Your programming machine will quickly become outdated if you don't take this step.
