Automotive Locksmith Key Programming
Modern cars need some type of key programming. Based on the car's make and model, the process can be as simple as onboard programming with a spare working key or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers to allow them to develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Transponder chips are found in a lot of modern cars to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has proven to be a huge success in preventing car theft. This technology has also saved car owners a great amount of money as they do not have to buy new vehicles.
The principle of the transponder system is to make it difficult for thieves to start your vehicle without a valid key. In the past, car thieves used the flat screwdriver to push the ignition switch in your car into the "on" mode or even hot-wire it in order to evade the system. These kinds of thefts have been dramatically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it transmits the signal which is picked up 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 car's onboard computer will then detect that the key is genuine and allow fuel to flow, turn the starter or begin it.
Certain vehicles only recognize a certain type of transponder chips according to the manufacturer. It is therefore important that your locksmith for cars is equipped with the correct 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 with different models and brands of cars. This is a cheaper option than purchasing separate tools for each brand of vehicle. These aren't as popular but there are automotive key programming tools that can only be used on a specific type of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you select a reputable firm that has this type of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. They also have buttons you can press to activate features like trunk release, door locks or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For example, a "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the help of a user manual but you'll usually need an automotive locksmith to have a new one programmed in case yours stops working. A professional locksmith is better equipped to connect the computer of your vehicle to the OBD port under the steering wheel.
The majority of key fobs today have security features that make it difficult for attackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code every time you press the key fob's button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances, you can purchase an additional key fob at the dealership or another retailer and have it programmed by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with the third-party firms who make the tools used by locksmiths for programming their customer's keys.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, professional locksmiths recommend against using them because they are likely to work poorly or even not at all. Instead, they recommend purchasing fobs that are specifically made for your specific vehicle so that you are certain they'll work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing the fobs.
