Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make the process could be as simple as using an additional key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian automakers use the same programming protocols as auto tool makers, so they can create tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are used in a lot of modern cars to prevent car theft. These are tiny computer microchips that emit low-level radio signals. The microchips have an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has been a huge success in preventing theft of cars. This technology has also helped car owners save a huge deal of money by not having to buy new vehicles.
The fundamental idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, thieves would simply force the ignition switch of your car into the "on" position with a flat screwdriver or even make use of hot-wires to bypass the system completely. These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip inside the key. The onboard computer of the car will then recognize the key as valid and allow fuel flow and power the starter to begin the engine.
Depending on the manufacturer, certain vehicles can only accept certain types of transponder chip. This is why it is essential to ensure that your automotive locksmith has the right equipment to program your car's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming tool that works with different car manufacturers and models. This is a less expensive alternative to purchasing specific tools for each type of vehicle. There are also specialised automotive key programmer devices that are only suitable for one particular brand of vehicle, but these are less popular. The best automotive locksmiths have the tools to work on any vehicle. Make sure you select a reputable firm that has this kind of equipment.
Key FOBs
Key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine using the push of a button. It is also possible to press buttons to trigger features such as trunk releases, door locks or fuel flap controls. Some fobs can be controlled using buttons. For instance, a "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from the user guide, however you'll need to contact an automotive locksmith if yours isn't working. This is because a professional locksmith has the right equipment and access to the tools for programming needed to connect your car's computer through the OBD (OBD) port beneath the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to clone and replicate the signals that they transmit. Some key fobs have pseudo-random code generators that generate a unique unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase an additional key fob at the dealer or from another retailer and have it programmable by your locksmith in your car to fit your specific vehicle. This is because most of the major US and Asian car manufacturers have key fob programming protocols with third-party companies that make the tools that locksmiths for auto use to program their customers' keys.
While some aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them because they're likely to work poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your specific vehicle so that you are certain they'll work properly and are less prone to issues such as interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
Automotive technologies have progressed a lot and modern vehicles require computers to function. One of the most important components of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. These key fobs are equipped with security features to prevent hot-wiring like in a film. The car will not start without the correct keys.
Key fobs are a bit more complex than your 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 differ based on the vehicle model and the website type of key however, they generally cost between $85 to $400. This includes labor costs to program the keyfob, as well as any replacement parts.
Car key fobs are more complex because they use a software system that works with the onboard computer of the car. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific car to function. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car to function.
The most common way to do this is by using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. Key programming devices can be a handheld device that's cheap or fancy and can do more than just programming keys (like reading the eeprom files in the ECU).
Although some people might attempt to program their own keys with these tools, this is an activity best left to an experienced auto locksmith. It's easy to make mistakes with the software systems if you aren't aware of the nuances. This could lead to damage. It's important to keep in mind that a professional with experience will assist you in avoiding these issues.
On-Board Programming
If your car is older than you, you'll still have a key from the past that you can use to open the doors and turn over the ignition. Modern cars come with transponder chips that must be recognized by the computer system of the car in order to start. This adds an extra layer of security that prevents car thieves from stealing a car and then driving off with the car. A certified locksmith will have the right tools and software to create a new key that will work with your car's security system.
Your locksmith will first need to purchase a key blank that is compatible with your vehicle's model and make. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will place the car into a special programing mode, which will allow locksmiths to add keys to the system.
To do this, the key programming scanner will communicate with the car's computer to send a particular code. The computer will detect this code and add it into the list of approved key. In some cases the scanner will be able to delete keys that are stolen or lost from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of how electronic systems function. This is why it should be left to a professional that has years of experience working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program a new key. If everything is done correctly it could take just one minute. However, if the key isn't placed in the correct condition or the procedure is not followed exactly, it can take as long as a half hour.
There are a variety of key programmer scanners that can be used with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their wide selection of vehicle models. However, neither will be able to program every vehicle on the market. In addition, these machines cost a lot. It is recommended to purchase an instrument that receives regular updates from the manufacturer as new technologies are released. In the event that your machine is not updated, it will become obsolete quickly.
