Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the process can be as simple as programming onboard using a spare working key or as complex as OBD2 or EEPROM programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers in order to create tools and hardware for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a 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 car doesn't recognise the signal, it will shut down the engine. This technology has proven to be an enormous success in preventing car theft. This technology has also saved car owners a great deal of money since they don't have to buy new vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to start your vehicle without a valid key. In the past, car thieves would force your car's ignition switch into the "on" position using the flat screwdriver, or use hot wires to disable the system completely. Transponder chips have drastically reduced these types of thefts.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to detect the specific frequency of the chip inside the key. The car's onboard computer will detect that the key is legitimate and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer certain vehicles can only accept a specific type of transponder chip. This is why it's crucial to make sure that your automotive locksmith is equipped to program your car's key and fobs properly.
A reputable locksmith for cars should have a multi-vehicle key programming tool that works with different car manufacturers and models. This is a cheaper alternative to purchasing separate tools for each brand of vehicle. These aren't as popular but there are automotive key programmers that are able to only work on a specific brand of vehicle. The top automotive locksmiths have the right tools to deal with any kind of vehicle, so ensure you choose a reputable business that has these types of tools.
Key FOBs
The name implies that key FOBs are home to the transponder chips that can be programmed to allow your vehicle to recognize and open the doors or start the engine using push-button ignition. You can also use the buttons to activate features like trunk releases, door locks or control of the fuel flap. Some fobs also have additional functions that can be controlled by the press of a button like the "smart" key fob that lets you bring your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself with the help of a user guide, but you'll need to call an automotive locksmith if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your car via the OBD port located under the steering wheel.
Most key fobs today have security features that make it difficult for criminals to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators which generate a unique unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal in order to gain access to your vehicle.
In most instances you can purchase an additional key fob at the dealership or another retailer and have it programmable by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that make the tools used by locksmiths who program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles However, the majority of locksmiths in the automotive industry don't recommend using them as they are likely to function poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Tool for programming the vehicle manufacturers
Automotive technology has progressed a lot and today's vehicles need computers to function. Transponder chips are an important part of this technology. It must be programmed by a locksmith, mechanic, or dealer to work. These key fobs have built-in security features that stop hot-wiring (like in a film) and the car won't start without the proper key.
Key fobs are a little more complex than your mechanical keys and are the reason you'll usually find them in the hands of a skilled professional auto locksmith. The cost of the car key fob can vary dependent on the type and model of key, but it is generally between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
To make the process more difficult the car key fobs use a special software system to work with the car's onboard computer. The software blocks access to unauthorised users by only allowing keys that have been programmed for a specific vehicle to function. This means that if your keys replaced, you'll need to have the new key fob programmed to the car in order for it to function.
This is accomplished using a tool for programming car keys that is compatible with the brand of your vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter programming mode. The key programming tool could either be an inexpensive handheld device or a more expensive one that can do various things that go beyond key programming (like reading and cloning the Eeprom files within the ECU).
While some people may attempt to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to make a mistake and alter settings that could potentially damage the vehicle. It's important to keep in mind that an experienced professional will assist you in avoiding these issues.
On-Board programming
If your car is old enough, you'll still have a traditional metal key to use to unlock the doors and turn over the ignition. However, modern vehicles are equipped with transponder read more chips that must be recognized by the computer system in order to start. This is a further security measure to prevent car thieves from starting and driving away with a stolen vehicle. A locksmith certified will have the tools and software necessary to program a key that can be compatible with your car's security system.
Your locksmith will first need to acquire a blank key compatible with your vehicle's make and model. Once the key is received the locksmith will connect the scanner for programming 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 programmer scanner communicates with the computer of the vehicle to send the code. The computer will recognize this code and include it to the list of approved key. In some cases the scanner will also delete lost or stolen keys.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough 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 a key quickly using onboard programming. It can take less than an hour if everything is completed correctly. If the key is not in the correct condition or the procedure isn't followed exactly, the process could be as long as half an hour.
There are many different key programmer scanners which can work with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they support a broad range of vehicles. There is no system that can program every vehicle. They are also expensive. It is best to buy one that will receive regular updates from the manufacturer as new technologies are introduced. If not, your computer will soon become obsolete.
