Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian car makers use the same programming protocols as auto tool manufacturers so that they can develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves of low-level. 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 shut down the engine. This technology has proved to be an immense success in stopping auto theft. This technology has also saved car owners a great amount of money by not having to purchase new cars.
The basic concept behind the transponder system is to make it impossible for thieves to start your vehicle without the correct key. In the past, car thieves would simply force your car's ignition switch into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system completely. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The onboard computer of the car will then recognise the key as being valid and allow fuel flow and power the starter to begin the engine.
Some vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming tool that is compatible with different car manufacturers and models. This is a more cost-effective approach than purchasing individual tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programming tools that can only work on a particular model of vehicle. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so make sure you choose a reputable business that has these types of tools.
Key FOBs
As the name implies, key FOBs are home to the transponder chips programmable that allow your vehicle to recognize and open the doors, or start the engine using push-button ignition. They also have buttons you can push to activate features such as trunk release, door locks or control of the fuel flap. Some fobs also have additional functions that can be controlled using the push of a button, such as a "smart" key fob that allows you to bring your car to parking spots that are tight, like you would with the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from the user guide, however you'll need to call an automotive locksmith if the one you have isn't functioning. A professional locksmith is better equipped to connect the computer of your vehicle via the OBD port located under the steering wheel.
Most key fobs today include security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random 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. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that create the tools used by auto locksmiths to program their customer's keys.
Certain key fobs from the aftermarket may be advertised as being compatible with vehicles of all kinds. However, professional locksmiths strongly discourage using them as they are likely to work poorly or even not even work at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have advanced considerably and modern vehicles require computer technology in order to function. A transponder chip is an essential part of this technology. It needs to 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 will not start if you don't have the right key.
Key fobs are a little more complex than the mechanical keys, which is why they are usually in the hands of an expert professional auto locksmith. The cost of a key fob can vary based on the vehicle model and the key type, but they typically run between $85 to $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
These car key fobs are more complex because they utilize software that interacts with the computer onboard of the car. The software prevents unauthorised access by only allowing keys that have been programmed specifically for a particular car to function. This means that if you need your keys replaced, you'll have to have the new key fob programed to the car in order for it to function.
The most common way to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter the programming mode. The key programming device could be an handheld device that is inexpensive or one that is sophisticated and capable of doing more than just programming keys (like reading the eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, this is an activity best left to a professional auto locksmith. If you're not aware of all the details of the various software systems, it's very easy to accidentally change settings that could cause damage to the vehicle. It's crucial to remember that an experienced professional will help you avoid these issues.
On-Board programming
If your car isn't as old, it may still come with a metal key that can be used to open doors and turn on the ignition. However, modern cars have a transponder chip that must be recognized by the computer system to begin. This adds another security measure to prevent car thieves from starting and driving away with a stolen vehicle. A certified locksmith will have the right tools and software to program a new key that is compatible with the security system in your car.
The locksmith needs to purchase an uncut key that is compatible with the model and make of your car. Once the key is in hand the locksmith will connect the programming scanner to your car's diagnostic port. This will put your car into an exclusive programming mode that will allow the locksmith to add a new key into the system.
The key scanner that is programmed communicates with the computer in the vehicle to transmit a code. The computer will be able to recognize the code and add it to the list of keys that are authorized. In some instances, the scanner will also be able to erase 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 thorough understanding of how electronic systems work. It's best to leave it to a professional with experience with these systems.
Locksmiths can program a key quickly using onboard programming. It can take as little as an hour if everything is executed correctly. If the key is not in the right condition or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are a variety of key programmer scanners available that support different car models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their broad range of vehicle models. The system cannot program every vehicle. They are also expensive. It's a good idea to purchase a programer that is updated regularly as the manufacturer releases new technologies. In the event that your machine is not updated, it will be obsolete in a short time.
