Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the car's maker and model, the procedure could be as simple as programming onboard using an extra working key or as complex as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips 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 whenever you insert it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. It has also saved many car owners a lot of money because they don't have to replace their cars.
The fundamental 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 simply force your ignition switch to the "on" position with an ordinary screwdriver or use hot wires to disable the system entirely. These types of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send the signal which is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip inside the key. The car's onboard computer will recognize that the key is valid and allow fuel to flow, turn up the starter or start it.
Some vehicles only recognize specific type of transponder chip according to the manufacturer. This is why it is essential to ensure that your locksmith for automotive is equipped to program your car's key and fobs correctly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that is compatible with different models and manufacturers of cars. This is a more cost-effective solution than buying specific tools for each type of vehicle. They are not as common, but there are specialised automotive key programmers that are able to only be used on a specific brand of vehicle. The top automotive locksmiths have the right tools to work on any type of vehicle, so make sure you choose a reputable business that has these types 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 push-button ignition. You can also press buttons to trigger features such as trunk locks, door locks or fuel flap controls. Some fobs can be controlled by pressing buttons. For instance, a "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from a user guide, but you'll need to call an automotive locksmith in the event that yours isn't functioning. This is because an expert locksmith has the specialized equipment and access to the tools for programming needed to connect your car's computer via the on-board diagnostics (OBD) port beneath the steering wheel.
Today, most key fobs include security features that make it difficult for attackers to duplicate or copy 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 stops attackers from recording and playing back the unlock signal to gain access to your vehicle.
In most cases you can buy a replacement key fob from the dealership or another retailer and then have it programmed by a locksmith for your vehicle to work with your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that produce the tools used by locksmiths who program their customer's keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, locksmiths for automotive strongly discourage using them as they are likely to work poorly or not work at all. They recommend buying fobs made specifically for your vehicle so that they function properly and are less susceptible to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.
Toolkits for Programming Vehicles of Manufacturers
The automotive industry has progressed a lot and today's vehicles need computers to function. One of the key components of this technology is a transponder chip which must be programmed into 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.
Key fobs are a bit more complex than your traditional mechanical keys and that's why you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob may differ based on the vehicle model and the type of key however, they generally cost between $85 and $400. This includes the labor required to program the key fob and the cost of any needed replacement parts.
These car key fobs are more complex due to the fact that they use software that interacts with the onboard computer of the car. The software blocks unauthorized access by only allowing the key to function only if it's programmed to the car in question. If you change your keys, you will need to program the new key fob to the car for it to function.
This is accomplished using a programing tool for keys for cars that are compatible with the vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a high-end one that can perform many things beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people might here attempt to program their keys by themselves using these tools. However this should be left to an expert auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's easy to make a mistake and alter settings that could cause damage to the vehicle. The most important thing to remember is that a skilled professional can assist you in avoiding these issues.
On-Board programming
If your vehicle is of a certain age that you'll have a key from the past to open the doors and turn on the ignition. However, modern cars have transponder chips that must be recognized by the computer system to allow it to start. This is an additional layer of protection that can stop car thieves from starting a stolen car and driving off with the car. A certified locksmith will have the necessary tools and software to program a new key that is compatible with the security system in your car.
First, your locksmith will require a blank key that is compatible with the model and make of your vehicle. 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 place the vehicle into a specific programming mode, which allows the locksmiths to add keys to the system.
To accomplish this, the key programmer scanner will communicate with the car's computer to send a particular code. The computer will detect this code and add it to the list of approved key. In certain situations the scanner will also delete lost or stolen keys.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a thorough 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 fastest way for a locksmith to program the new key. If everything is done properly it can take just one minute. However, if the key isn't placed in the right situation or the procedure is not adhered to, it could take up to an hour.
There are many key programmer scanners that can be used with different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they cover a wide range of vehicle models. There is no system that can program every vehicle. They are also expensive. It is best to buy an instrument that receives regular updates from the manufacturer as new technologies are developed. Your computer's programming software will soon become obsolete if you don't do this.
