Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the car's maker and model, the process can be as simple as programming onboard using a spare working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to prevent car theft. These are tiny computer microchips that emit radio signals at a low level. They have an unique serial number that authenticates your key when you insert it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has proven to be an enormous success in preventing auto theft. It also saves many car owners a lot of money as they don't have to buy new their cars.
The transponder system's basic idea is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, thieves used the flat screwdriver to push the ignition switch in your car into "on" mode, or hot-wire it to evade the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The onboard computer in the car will then recognize the key as valid and will allow fuel flow and power the starter to start the engine.
Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip. This is why it is essential to ensure that your automotive locksmith has the right equipment to program your car's key and fobs properly.
A reputable locksmith for cars should have a multi-vehicle key programming device that works with different car manufacturers and models. This is a much cheaper option than buying individual tools for each brand 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 common. The top automotive locksmiths have the proper tools to work on any type of vehicle, so make sure you find a reputable company with these kinds of tools.
Key FOBs
As the name suggests, key FOBs house the programmable transponder chips that allow your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons that you can press to trigger features such as door locks, trunk release or control of the fuel flap. Certain fobs can be controlled using buttons. For instance an "smart key" which allows you to summon your car to parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from the user guide, however you will need to call an automotive locksmith if yours isn't functioning. A professional is better equipped to connect your computer to the vehicle via the OBD port under the steering wheel.
The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals that they transmit. These include pseudo-random sequence generators that generate a new unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.
In some cases, you can buy a replacement keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your car. 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 make the tools used by locksmiths who program their customers' 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're more likely to perform poorly or not even work at all. Instead, they suggest purchasing fobs designed specifically for your vehicle, so that you can be certain they'll work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing your fobs.
Tool for programming the vehicle manufacturers
The automotive industry has come a long way, and today's vehicles require computer technology in order to function. A transponder chip is an essential component of this technology. It needs to be programmed by a locksmith, mechanic or dealer to work. Key fobs come with built-in security features that stop hot-wiring (like in a movie) and the car won't start if it doesn't have the correct key.
These key fobs are a bit more complex than the mechanical keys and are the reason they are usually in the hands of an expert, professional auto locksmith. The cost of the car key fob is dependent on the type and model of key, but it is usually between $85 to $400. This includes the cost of labor to program the keyfob and any replacement parts.
To complicate the process the car key fobs make use of a special software to work with the car's onboard computer. The software blocks unauthorized access by only allowing the key to operate only if it's been programmed to that here specific car. This means that if your keys replaced, you'll have to have the new key fob programed to the car in order to function.
The most common way to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. The key programming tool could either be an inexpensive handheld device or a more expensive one that can do various things beyond key programming (like reading and cloning eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, it's an activity best left to an experienced auto locksmith. It is easy to make mistakes using the software systems if you don't know the nuances. This could result in damage. The most important thing to keep in mind is that an experienced professional can assist you in avoiding these issues.
On-Board programming
If your car isn't as old, it may still come with a key made of metal that you can use to open doors and turn on the ignition. Modern cars have transponder chips that must be recognized by the computer system to allow it to start. This is an additional layer of security that stops car thieves from starting a car stolen and driving away with the car. A locksmith who is certified has the tools and software necessary to program a key that will work in your car's system.
First, your locksmith will require a blank key that is compatible with the model and make of your car. Once the key is in hand, your locksmith will link the scanner for programming to the diagnostic port of your car. This will put the vehicle into the mode of programming that allows the locksmith to add a new key to the system.
To accomplish this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will be able to recognize the code and add it to the list of keys approved by. In some cases, the scanner will also be able to delete keys that are stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complicated and requires a thorough understanding of how electronic systems operate. This is why it should be left to a professional who has extensive experience working with these kinds of systems.
Onboard programming is the fastest method for locksmiths to program the new key. It can take as little as one minute if everything is done correctly. If the key isn't in the right condition or the procedure isn't followed exactly, the process could take up to half an hour.
There are numerous key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide selection of models for vehicles. No system can program every vehicle. In addition, these machines cost a lot. It's a good idea to purchase a computer that will get regular updates as the manufacturer develops new technologies. In the event that your machine is not updated, it will soon become obsolete.
