Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using an additional key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can create software or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves at a low level. The microchips 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 it will shut down. This technology has been extremely successful in preventing theft of cars. It has also saved many car owners a significant amount of money because they don't have to replace their cars.
The principle of the transponder system is to make it hard for thieves to start your vehicle without a valid key. In the past, thieves used the flat screwdriver to push the ignition switch of your car into "on" mode or even wire it hot to evade the system. Transponder chips have drastically reduced the number of thefts.
When you place the transponder key in the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then detect that the key is genuine and allow the fuel to flow, then power the starter or start it.
Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. Therefore, it is essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming tool that is compatible with different car manufacturers and models. This is a cheaper option than purchasing separate tools for each brand of vehicle. There are also specific key programming devices for automotive that can only be used on specific models of vehicles however, they are less popular. The best automotive locksmiths will have the right tools to work on any type of vehicle, so make sure you choose a reputable firm that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to unlock doors and start the engine with a push button ignition. It is also possible to press buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Some fobs can be controlled using buttons. For example the "smart key" that allows you summon your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the assistance of a user's manual but you'll usually need an automotive locksmith to have a new one programmed if yours stops working. This is because an expert locksmith has the right equipment and access to the programming tools required to connect your car's computer to the OBD (OBD) port beneath the steering wheel.
Today, most key fobs include security features that make it difficult for attackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the key fob's button. This is to prevent attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some instances, you can buy a replacement keyfob from a dealership 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 manufacturers use key fob programming protocols with third-party companies that produce the tools locksmiths for auto employ to program their customers' keys.
Certain key fobs from the aftermarket may be marketed as being compatible with vehicles of all kinds. However, professional locksmiths recommend against using them because they are likely to work poorly or not work even work at all. Instead, they suggest buying fobs designed specifically for your vehicle, so that you can be sure they'll function properly and be less prone to issues such as interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.
