Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on your vehicle's model and make the procedure could be as simple as using an extra key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers share their programming protocols with auto tool manufacturers so that they can develop tools and hardware for locksmiths working in automotive vehicles.
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 radio signals at a low level. They have a unique serial number which authenticates your keys 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 been an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money as they do not have to purchase new cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past car thieves would use a flat screwdriver to force the ignition switch of your car to go into "on" mode or even hot-wire it to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which 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 computer onboard will recognize that the key is legitimate and allow fuel to flow, turn up the starter, or even start it.
Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.
A reputable locksmith for automotive will have a multi-vehicle programming device that can be used on many different automobile models and manufacturers. This is a less expensive alternative to purchasing specific tools for each type of vehicle. These are less common however, there are specialist automotive key programmers that are able to only work on a specific type of vehicle. The best automotive locksmiths will have the right tools to work on any type of vehicle, so ensure you choose a reputable business with these kinds of tools.
Key FOBs
As the name implies, key FOBs contain transponder chips programmable that enable your car to recognize and unlock the doors, or start the engine with a push-button ignition. They also have buttons that you can push to activate features such as door locks, trunk release or fuel flap control. Some fobs can be controlled with the press of buttons. For instance an "smart key" that lets you call your car to parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself using the help from an instruction manual, however you will need to call an automotive locksmith if the one you have has stopped functioning. A professional locksmith is better equipped to connect the computer of your vehicle via the OBD port on the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to clone and replicate the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code every time you press the key fob's button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your car.
In certain instances, you can buy an alternative keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your car. This is because most of the major US and Asian car makers share their key fob programming protocols with third-party companies who create the tools locksmiths use to programme keys for their customers.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles However, the majority of locksmiths in the automotive industry do not recommend using them because they will likely only work poorly or not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements of your fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has progressed a lot, and today's vehicles require computer technology in order to function. One of the key components of this technology is a transponder chipset that must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs come with built-in security features that prevent hot-wiring (like in a movie) and the car will not start if you don't have the correct key.
These key fobs are more complicated than a traditional mechanical key, which is why you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob will vary based on the vehicle model and the key type however they usually cost between $85 to $400. This includes the labor cost to program the keyfob as well as any replacement parts.
To make the process more complicated, these car key fobs make use of a special software to work with the car's onboard computer. The software blocks access to unauthorized users by only allowing the key to function if it has been programmed to the car in question. If you replace your keys, you'll need to program the new key fob to the car in order for it to function.
The most popular method 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) in the vehicle and then enter a programming mode. Key programming tools can either be an inexpensive handheld device or a more expensive one that can perform many things beyond key programming (like reading and cloning eeprom files in the ECU).
While some may try to program their own keys with these tools, it's a job best left to a professional auto locksmith. It's easy to make a mistake using the software systems if you don't understand the intricacies. This could result in damage. The most important thing to remember is that a professional with experience can assist you in avoiding these issues.
On-Board programming
If your car is older than that it has a key, it might still come with a metal key that can be used to open doors and turn on the ignition. Modern vehicles have a transponder that must be recognized and accepted by the computer system before it can start. This is a further layer of security to keep thieves from stealing the car and then driving off with a stolen vehicle. A locksmith certified will have the tools and software required to program a key that will be compatible with your car's security system.
First, your locksmith needs to purchase a blank key that is compatible with the model and make of your car. Once automotive key programming has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will place the car into an exclusive programming mode which will allow the locksmith to add a new key to the system.
To do this, the key programming scanner will communicate with the car's computer and send a particular code. The computer will detect the code and add it into the list of keys that are authorized. In certain instances, the scanner will also be able to delete lost or stolen keys from the system.
You can also program new keys using EEPROM. It is more complex and requires a deep understanding of electronic systems. It is best to leave it to a professional with knowledge of these systems.
Locksmiths can program a key quickly by using onboard programming. When everything is done correctly it can take as little as one minute. If the key is not in good working order or the procedure isn't followed precisely, the procedure could take up to half an hour.
There are a variety of key programmer scanners available that work with various vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they can be used with a variety of automobile models. The system cannot program every vehicle. They are also expensive. It is best to buy an instrument that receives regular updates from the manufacturer whenever new technologies are introduced. Your programming machine will quickly become obsolete if you don't do this.
