Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming with an extra working key or as complex as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers in order to create hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be an immense success in stopping auto theft. It also saves 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 get into your vehicle without a valid key. In the past, car thieves would use a flat screwdriver to force the ignition switch in your car to go into "on" mode or even wire it hot to evade the system. Transponder chips have drastically 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. This antenna is programmed with the frequency of the chip inside the key. The computer onboard of the car will then recognise the key as being valid and will allow fuel flow and start the starter. start the engine.
Depending on the manufacturer certain vehicles can only accept the specific type of transponder chip. It is therefore essential that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will have a multi-vehicle programming tool that can be used on a variety of 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 specialised automotive key programmers that can only be used on a specific type of vehicle. The most reliable automotive locksmiths will have the appropriate tools to work on any type of vehicle, so be sure you find a reputable company 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. You can also press buttons to activate features like trunk locks, door locks or controls for the fuel flap. Some fobs have additional functions that can be controlled by the push of a button, such as the "smart" key fob that lets you bring your car into tight parking spots as you would with a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the help of a user manual but you'll usually require an auto locksmith to have a new one programmed if yours stops functioning. This is because a professional locksmith has the specialized equipment and access to the programming tools required to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
Today, most key fobs have security features that make it difficult for hackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators that generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy an alternative keyfob from an authorized dealer or another retailer. Your locksmith at your auto will then program it to work with your car. This is because most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party firms that produce the tools auto locksmiths utilize to program their customers' keys.
Although some key fobs from the aftermarket are advertised as compatible with all vehicles, most automotive locksmiths do not recommend using them as they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has come a long way, and today's vehicles require computers to function. One of the most important components of this technology is a transponder chip that requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs with embedded security features that stop hot-wiring (like in a film) and the car will not start if you don't have the proper key.
Key fobs are a bit more complex than your traditional mechanical keys and that's why they are usually in the hands of a skilled, professional auto locksmith. The cost of the car key fob can vary dependent on the model and type of key, but is usually between $85 and $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.
These car key fobs are more complicated because they utilize an operating system that communicates with the onboard computer of the car. The software blocks access by unauthorised persons by only allowing keys that have been programmed specifically for a particular car to work. If you decide to replace your keys, you will need to program the new key fob in the car for it to work.
The most common way to do this is by using the car key programming tool that is compatible with the brand of the vehicle. This tool permits a locksmith to connect to the OBD port on the vehicle and then enter the programming mode. The key programming device can be an handheld device that is inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom file inside the ECU).
While some may try to program their own keys using 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 know the nuances. This could result in damage. It's important to keep in mind that a professional with experience will help you avoid these issues.
On-Board Programming
If your car is old enough, it may still come with a key made of steel that you can use to unlock doors and turn the ignition. Modern cars come with a transponder that must be recognized and accepted by the computer system before it can start. This is an additional layer of security to keep car thieves from starting and driving away with a stolen vehicle. A locksmith who is certified has the tools and software to program a new key that works with the security system in your car.
Your locksmith will need to purchase a blank key compatible with your vehicle's model and make. Once the key is received, your locksmith will link the scanner for programming to the diagnostic port of your car. This will place the car into a special programming mode which will allow the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer of the car to send a code. The computer will recognize this code and include it into the list of approved key. In some instances scanners can remove keys that have been stolen or lost.
You can also program new keys by using the EEPROM. It is more complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional who has years of expertise working on these types of systems.
Onboard programming is the quickest way for a locksmith to program the new key. It can take as little as one minute if everything is executed correctly. However, if the key isn't in proper situation or the procedure isn't followed exactly, it can take up to a half hour.
There are many different key programmer scanners that support different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide selection of models for vehicles. However, neither can be programmed for every vehicle on the market. These machines are also quite expensive. It is best to buy an instrument that receives regular updates from the manufacturer as new technologies are introduced. Otherwise, your programming machine will be obsolete in a short time.
