Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on your vehicle's model and manufacturer the process could be as simple as using a spare key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers share their programming protocols with auto tool manufacturers so that they can develop software and hardware for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has been an enormous success in preventing auto theft. This technology has also helped car owners save a huge amount of money since they don't have to buy new vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to start your car without the proper key. In the past car thieves used a flat screwdriver to force the ignition switch of your car to go into "on" mode or even hot-wire it in order to evade the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys in the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip inside the key. The onboard computer of the car will then recognise the key as valid and allow fuel flow, power the starter or start the engine.
Based on the manufacturer, certain vehicles can only accept a specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different car manufacturers and models. This is a less expensive option than purchasing separate tools for each brand of vehicle. They are not as common, but there are specialised automotive key programming tools that can only work on a particular type of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and begin the engine with the push of a button. You can also press buttons to activate features such as trunk releases, door locks or controls for the fuel flap. Some fobs can be controlled with the press of buttons. For instance the "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from a user guide, but you'll need to contact an automotive locksmith if yours has stopped functioning. A professional locksmith is better equipped to connect your computer to the vehicle to the OBD port located under the steering wheel.
Most key fobs today have security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the button on the key fob. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your vehicle.
In most cases you can buy an additional key fob at the dealership or another retailer and have it programmed by your locksmith in your car to be compatible with your specific vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that create the tools used by auto locksmiths to program their customer's keys.
Some aftermarket key fobs may be advertised as being compatible with vehicles of all kinds. However, automotive locksmiths advise against using them since they're more likely to perform poorly or even not at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing your fobs.
