Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer, the process may be as simple as using an additional key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool makers, so they can develop software or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have a unique serial number which authenticates your keys when you plug it into the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has proved to be an incredible success in preventing auto theft. It also saves many car owners a lot of money as they don't need to replace their cars.
The principle behind the transponder system is to make it difficult for thieves to get into your car without a key. In the past, car thieves would simply force the ignition switch of your car into the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system altogether. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's computer onboard will recognize that the key is genuine and allow the fuel to flow, then power the starter or begin it.
Depending on the manufacturer certain vehicles can only recognize certain types of transponder chip. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that works with different car manufacturers and models. This is a far more cost-effective approach than purchasing individual tools for each brand of vehicle. These are less common but there are automotive key programmers that can only be used on a specific brand of vehicle. The top automotive locksmiths have the tools to work on any vehicle. Make sure you choose a reliable company that is equipped with this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. You can also use the buttons to trigger features such as trunk releases, door locks or fuel flap controls. Certain fobs come with additional functions that can be controlled by the button presses like the "smart" key fob that allows you to summon your car into parking spaces that are difficult to access, like you would with the Genesis GV60 or Tesla.

The majority of key fobs today come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a fresh unlock code every time you press the key fob's button. This prevents attackers capturing and replaying the unlock signal in order to gain access to your car.
In many cases you can purchase an alternative key fob from the dealership or another retailer and then have it programmed by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of the major US and Asian car makers use key fob programming protocols with third-party companies who produce the tools auto locksmiths use to programme keys for their customers.
While some aftermarket key fobs are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them because they will likely only 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 function properly and be less prone to issues like interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has come a long way, and today's vehicles require computers to function. One key element 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. These key fobs are equipped with security features that prevent hot-wiring, as in a film. The car will not start if the keys are click here not correct.
These key fobs can be slightly more complicated than a traditional mechanical key. This is why they are in the hands of seasoned, professional auto locksmiths. The cost of a car key fob varies according to the model and type of key, but it is typically between $85 to $400. This includes the labor required to program the key fob, as well as the costs for any required replacement parts.
Car key fobs are more intricate because they use software that interacts with the computer onboard of the car. The software blocks unauthorized access by allowing the key to operate only if it's been programmed for the specific car. This means that if you need your keys replaced, you'll have to have the new key fob programmed to the car for it to function.
This is accomplished using a programing tool for car keys that is compatible with the vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter the programming mode. The key programming tool can be a simple handheld device or a more expensive one that is capable of performing a wide range of things that go beyond key programming (like reading and cloning Eeprom files within the ECU).
While some may try to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. If you're not familiar with the aspects of the various software systems, it's possible to make a mistake and alter settings that could damage the vehicle.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. This is why it should be left to a professional that has extensive expertise working on these types of systems.
Locksmiths can program a key quickly using onboard programming. If everything is done correctly it can take as little as one minute. If the key isn't in the right state or the procedure is not adhered to, it could take up to an hour.
There are numerous key programmer scanners which can work with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of models for vehicles. However, no system will be able to program every single vehicle that exists. In addition, these machines are expensive. It's a good idea purchase a programer that is updated regularly when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you don't take this step.
