Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer the process could be as simple as using an additional key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has been a huge success in preventing car theft. This technology has also saved car owners a great deal of money by not having to purchase new cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, thieves used a flat screwdriver to force the ignition switch of your car into the "on" mode, or wire it hot to evade the system. These types of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
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 in the key. The computer onboard of the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Based on the manufacturer, certain vehicles can only accept the specific type of transponder chip. It is therefore essential that your locksmith in the automotive industry is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different car manufacturers and models. This is a more cost-effective alternative to purchasing specific tools for each type of vehicle. There are also specially-designed key programming tools for automobiles that can only be used on specific brands of vehicles, but these are less popular. The best automotive locksmiths will have the proper tools to deal with any kind of vehicle, so ensure you choose a reputable firm that has these types of tools.
Key FOBs
As the name implies, key FOBs house the transponder chips programmable that allow your vehicle to identify and unlock the doors, or start the engine with a push-button ignition. They also have buttons you can press to trigger features such as door locks, trunk release or control of the fuel flap. Some fobs can be controlled by pressing buttons. For example the "smart key" which allows you to summon your car into tight parking spaces, like a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual, you'll often need an automotive locksmith to get a brand new one programmed if the one you have isn't functioning. A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
The majority of key fobs come with security features that make it more difficult for criminals to duplicate and copy the signals they transmit. They include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some instances you can purchase the replacement keyfob at an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is because most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party companies that produce the tools locksmiths utilize to program their customers' keys.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, professional locksmiths recommend against using them because they're more likely to perform poorly or not at all. They suggest buying fobs designed 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 in the long run by avoiding costly repairs or replacing the fobs.
Tool for programming the vehicle manufacturers
Automotive technologies have advanced considerably and modern vehicles require computers to function. One of the most important components of this technology is a transponder chip that requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to prevent hot-wiring like in a film. The car won't start if the keys are not correct.
These key fobs are a bit more complex than the mechanical keys and that's why they are usually in the hands of a reputable professional auto locksmith. The cost of a key fob will vary depending on the car model and the type of key, but they typically run between $85 to $400. car key programmers includes the cost of labor to program the keyfob and any replacement parts.
These car key fobs are more intricate because they utilize software that interacts with the computer onboard of the car. The software blocks access by unauthorised persons by only permitting keys that have been programmed for a specific vehicle to function. This means that if you need your keys replaced, you'll need have the new key fob programmed 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 model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. Key programming tools can be a simple handheld device or a high-end one that can perform various things beyond key programming (like reading and cloning EEEPROM files in the ECU).
While some people may attempt to program their own keys with these tools, it's a job best left to a professional auto locksmith. If you're not aware of all the aspects of the various software systems, it's very easy to make a mistake and alter settings that could damage the vehicle. The most important thing to remember is that a skilled professional can assist you in avoiding these problems.
On-Board programming
If your car is old enough to be considered old-fashioned, you'll have a traditional metal key that you can use to open the doors and turn over the ignition. Modern cars have transponders that must be recognized and accepted by the computer system to start. This is a further layer of security that prevents car thieves from starting and driving away with a stolen vehicle. A locksmith who is certified has the tools and software required to program a key that will function in your car's system.
The locksmith will need to get an uncut key that is compatible with the make and model of your vehicle. Once the key is in your possession, your locksmith will link the scanner for programming to your car's diagnostic port. This will put your car into a special programing mode, which allows locksmiths to add keys to the system.
The key scanner is programmed to communicate with the computer of the vehicle to send an electronic code. The computer will be able to recognize the code and add it to the list of keys that are approved. In some instances the scanner will also erase keys that were stolen or lost.
You can also program new keys with EEPROM. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional that has years of experience working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program the new key. It takes as little as an hour if everything is executed correctly. However, if the key isn't in proper situation or the procedure is not followed exactly, it can take as long as a half hour.
There are many key programmer scanners on the market that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely well-liked by locksmiths due to the fact that they support a broad range of vehicles. However, neither can be programmed for every single vehicle that exists. Furthermore, these systems are quite expensive. It is best to buy a programmer which will receive regular updates from the manufacturer when new technologies are introduced. Otherwise, your programming machine will be obsolete in a short time.
