Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and manufacturer, the process may be as simple as using an extra key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a variety of newer vehicles to stop theft of cars. These are microchips in the form of computers that emit low-level radio signals. They have an unique serial number that authenticates your keys when you plug it into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proved to be an incredible success in preventing auto theft. This technology has also helped car owners save a good amount of money by not having to purchase new cars.
The basic concept behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would simply push your ignition switch to the "on" position using the flat screwdriver, or use hot wires to disable the system entirely. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder key into the ignition the signal is picked up by an antenna that is concealed around the barrel. The antenna is programmed with the frequency of the chip within the key. The onboard computer in the car will recognize the key as valid and allow fuel flow and power the starter to start the engine.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. Therefore, it is essential that your automotive locksmith is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that works with different models and car brands. This is a cheaper option than purchasing individual tools for every brand of vehicle. There are also specialised key programming tools for automobiles that are only suitable for specific models of vehicles however they are not as frequently used. The best automotive locksmiths will have the proper equipment to tackle any type of vehicle, so be sure you find a reputable company that offers these types of tools.
Key FOBs
As the name suggests, key FOBs contain programmable transponder chips that enable your car to recognize and unlock the doors, or start the engine with a push-button ignition. It is also possible to press buttons to trigger features such as trunk releases, door locks or control of the fuel flap. Some fobs can be controlled by pressing buttons. For instance an "smart key" that lets you call your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help from a user guide, but you will need to call an automotive locksmith in the event that yours isn't working. This is because a professional has the right equipment and access to the programming tools required to connect your car's computer through the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs are equipped with security features that make it more difficult for criminals to duplicate and copy the signals that they transmit. Certain key fobs feature pseudo-random code generators, which generate a unique unlock code each time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase an alternative keyfob from an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of the major US and Asian car makers share their key fob programming protocols with third-party firms that produce the tools auto locksmiths utilize to program keys for their customers.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, locksmiths for automotive recommend against using them because they are likely to work poorly or not work at all. They suggest buying fobs designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
The automobile industry has made significant strides in the last few decades. Today's vehicles are computer-driven. A transponder chip is an essential part of this technology. It must be programmed by a locksmith mechanic, or dealer to work. Key fobs come with security features that prevent hot-wiring like in a film. The car won't start without the correct keys.
Key fobs are more complex than the traditional mechanical key and are the reason you'll typically find them in the hands of a skilled professional auto locksmith. The cost of the car key fob can vary depending on the type and model of key, but it is usually between $85 and $400. This includes the labor to program the key fob as well as the cost of any needed 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 unauthorized users by allowing the key to function if it has been programmed to the car in question. This means that if you need your keys replaced, you'll need have the new key fob programed to the car for it to function.
The most popular method to do this is by using an auto key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming device could be a handheld device that's inexpensive or one that is sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).
While some may try to program their own keys more info with these tools, this is an activity best left to a professional auto locksmith. It's easy to make a mistake with the software systems if you don't know the intricacies. This could lead to damage. The most important thing to keep in mind is that a skilled professional can help you avoid these issues.
On-Board Programming
If your car isn't as old it could still be equipped with a key made of metal that can be used to open doors and turn the ignition. However, modern vehicles come with a transponder chip that must be recognized by the computer system in order to start. This is an extra layer of protection that can stop car thieves from starting a car stolen and driving off with the car. A locksmith who is certified has the tools and software to create a new key that works with your car's security system.

Once the key is in hand the locksmith will connect the scanner for programming to the diagnostic port of your car. This will put your vehicle into a specific programming mode, which allows the locksmiths to add keys to the system.
To do this, the key programmer scanner will communicate with the car's computer and send a particular code. The computer will detect this code and include it to the list of keys that are authorized. In some instances, a scanner can 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 complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional that has a lot of experience working on these types of systems.
Locksmiths can program a key quickly with onboard programming. It takes as little as an hour if everything is done correctly. If the key isn't in the proper state or the procedure is not adhered to, it could take up to an hour.
There are many key programmer scanners that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they cover a wide range of vehicles. However, no system can be programmed for every single vehicle that exists. Furthermore, these systems are expensive. It's a good idea purchase a programer that will get regular updates when the manufacturer introduces new technologies. If not, your computer will soon become obsolete.
