Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the model and make the procedure could be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
The majority of newer cars have transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. The microchips are equipped with an unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft. It has also saved many car owners a lot of money since they don't have to buy new their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to start your car without the right key. In the past, thieves would force your car's ignition switch into the "on" position using the flat screwdriver, or hot-wire the car to bypass the system altogether. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder key into the ignition, it will transmit a signal that is received 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 car's onboard computer will then detect that the key is valid and allow the fuel to flow, then power the starter or start it.
Based on the manufacturer, certain vehicles can only accept the specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the correct equipment to program your car's keys and remotes.
A reputable locksmith for automotive will possess a multi-vehicle programing tool that can be used with different models and brands of cars. This is a cheaper option than purchasing separate tools for each brand of vehicle. These are less common but there are automotive key programmers that are able to only work on a specific model of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Make sure you choose a reliable company that is equipped with this kind of equipment.
Key FOBs
As the name suggests, key FOBs contain transponder chips programmable that enable your vehicle to recognize and open the doors, or start the engine with a push-button ignition. You can also press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled by pressing buttons. For instance an "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the assistance of a user's manual, you'll often require an auto locksmith to get a brand new one programmed in case yours stops working. This is because a professional has the equipment that is specialized and access to the programming tools needed to connect your car's computer through the on-board diagnostics (OBD) port beneath the steering wheel.
Most key fobs today come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase an alternative key fob from the dealer or other retailer and have it programmable by your automotive locksmith to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with the third-party companies who create the tools used by locksmiths for programming their customers' keys.
While some aftermarket key fobs are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them since they are likely to function poorly or not at all. Instead, they suggest purchasing fobs designed specifically for your vehicle, so that you are certain they'll function properly and be less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has made great advancements in the past few decades. Nowadays, cars are computer-driven. A transponder chip is an essential component of this technology. It needs to be programmed by a locksmith, mechanic or dealer to work. These key fobs are equipped with security features to prevent hot-wiring like in a movie. The car will not start if the keys are not correct.
These key fobs are more complex than your mechanical keys and that's why you'll typically find them in the hands of an expert professional auto locksmith. The cost of a key fob can vary based on the vehicle model and the type of key however they usually 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 utilize a specific software system to communicate with the car's onboard computer. The software blocks access to unauthorized users by allowing the key to function if it has been programmed to that specific car. If you change your keys, you'll have to program the new key fob to the car in order for it to function.
This is accomplished 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) within the vehicle and then enter an programming mode. The key programming tool can be a simple handheld device or a high-end one that can perform various things beyond just key programming (like reading and cloning the Eeprom files within the ECU).
Some people might try to program their keys by themselves using these tools. However it's best to leave this task to an expert auto locksmith. It's easy to make a mistake when using software systems if you don't understand the intricacies. This could result in damage. The most important thing to remember is that an experienced professional can help you avoid these issues.
On-Board programming
If your car is old enough that you'll have a traditional metal key to open the doors and turn on the ignition. Modern cars come with transponders that must be acknowledged and accepted by the computer system before it can start. This is an additional layer of security that prevents thieves from starting and driving away with a stolen vehicle. A licensed locksmith will have the right tools and software to create a new key that is compatible with the security system in your car.
Your locksmith will have to obtain a key blank that is compatible with your vehicle's model and make. Once the key is received the locksmith will connect the scanner that is used for programming to the diagnostic port of your car. This will put your car into the mode of programming which will allow the locksmith to add a new key into the system.
The key scanner is programmed to communicate with the computer of the car to send an electronic code. The computer will detect this code and add it into the list of keys that are authorized. In some cases, a scanner can also remove keys that have been stolen or lost.
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's best left to a professional that has a lot of expertise working on these types of systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. When everything is done correctly, it can take as little as one minute. However, if the key isn't placed in the proper condition or the procedure is not adhered to, it could take up to an hour.
There are a variety of key programmer scanners available that support different vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular with here locksmiths since they cover a wide range of automobile models. The system cannot program every vehicle. In addition, these machines cost a lot. It is recommended to purchase a programmer which will receive regular updates from the manufacturer as new technologies are developed. Your programming machine will quickly become obsolete if you do not do this.
