Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and make the process could be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to stop theft of cars. These are tiny computer microchips which emit radio waves at a low level. The microchips have a unique serial number which authenticates your key 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 proven to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money by not having to replace their vehicles.
The principle behind the transponder system is to make it difficult for thieves to open the doors of your car without a key. In the past, car thieves would simply force your ignition switch to the "on" position using an ordinary screwdriver or use hot wires to disable the system entirely. These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send an electrical signal that is received by a hidden antenna around the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will recognize the key as being valid and allow fuel flow and power the starter to begin the engine.
Some vehicles only recognize certain type of transponder chips according to the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will utilize a multi-vehicle programmable device which can be used on a variety of different automobile models and manufacturers. This is a less expensive solution than buying specific tools for each type of vehicle. They are not as common but there are automotive key programmers that are able to only work on a particular brand of vehicle. The best automotive locksmiths will have the proper tools to deal with any kind of vehicle, so be sure you choose a reputable firm that offers these types of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and start the engine with a push button ignition. You can also press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled using buttons. For example the "smart key" that lets you call your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the aid of a user's guide but you'll usually require an auto locksmith to get a new one programmed if the one you have isn't working. A professional is better equipped to connect the computer of your car via the OBD port on the steering wheel.
Today, most key fobs come with security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code each time you press the button. This prevents attackers capturing and playing back the unlock signal to gain access to your car.
In most instances you can purchase an alternative key fob from the dealer or other retailer and have it programmable by your automotive locksmith to work with your particular vehicle. This is because the majority of the major US and Asian car manufacturers share their key fob programming protocols with third-party firms that create the tools locksmiths for auto use to program their customers' keys.
Although some key fobs from the aftermarket are advertised as compatible with all vehicles However, the majority of locksmiths in the automotive industry do not recommend using them as they are likely to function poorly or not at all. Instead, they suggest buying fobs specifically designed for your vehicle so that you can be certain they'll function properly and be less prone to issues like interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing the fobs.
