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 a spare key to program the onboard computer or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can create tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number which authenticates your key whenever you plug it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be a huge success in preventing car theft. This technology has also helped car owners save a good deal of money as they do not have to purchase new cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to get into your car without a key. In the past, car thieves would use a flat screwdriver to force the ignition switch in your car into the "on" mode, or hot-wire it in order to get around the system. Transponder chips have drastically reduced these types of thefts.
When you insert the transponder key in the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, some vehicles will only recognise the specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A reputable locksmith for cars should have a multi-vehicle key programming device that can work on many different models and car brands. This is a much cheaper option than buying individual tools for each brand of vehicle. There are also specialised automotive key programmer devices that are only suitable for specific brands of vehicles, but these are less popular. The top automotive locksmiths have the right tools to deal with any kind of vehicle, so be sure you find a reputable company with these kinds of tools.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and start the engine with the push of a button. You can also press buttons to activate features like trunk locks, door locks or controls for the fuel flap. Some fobs also have additional functions that can be controlled using the button presses like a "smart" key fob that lets you get your car into parking spaces that are difficult to access as you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from the user guide, however you will need to call an automotive locksmith if yours has stopped functioning. This is because a professional 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 duplicate and copy the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on your key fob. This stops attackers from recording and playing back the unlock signal in order to gain access to your car.
In most cases you can buy an alternative key fob from the dealer or from another retailer and have it programmable by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that produce the tools used by locksmiths for programming their customers' keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, professional locksmiths recommend against using them because they are likely to work poorly or not work even work at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements of your fobs.
