Automotive Locksmith Key Programming
Most modern-day cars require some type of key programming. Based on the model and manufacturer the process could be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers in order to create software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio signals at a low level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proved to be an incredible success in preventing auto theft. It has also saved many car owners a significant amount of money as they don't need to replace their vehicles.
The fundamental idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past car thieves would use the flat screwdriver to push the ignition switch of your vehicle to go into "on" mode or even hot-wire it in order to get around the system. These kinds of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will send a signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will then recognize that the key is valid and allow fuel to flow, power up the starter or start it.
Some vehicles only recognize certain type of transponder chips according to the manufacturer. This is why it's essential to ensure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs properly.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different models and manufacturers of cars. This is a cheaper solution than buying specific tools for each type of vehicle. There are also specialised key programming devices for automotive that are only suitable for one particular brand of vehicle however they are not as frequently used. The most reliable automotive locksmiths will have the right tools to work on any type of vehicle, so ensure you find a reputable company that has these types of tools.
Key FOBs

You can also use the buttons to trigger features such as trunk locks, door locks or controls for the fuel flap. Some fobs can be controlled by pressing buttons. For instance the "smart key" that lets you call your car into tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual, you'll often need an automotive locksmith to have a new one programmed if the one you have isn't working. This is because a professional locksmith has the specialized equipment and access to the tools for programming needed to connect your car's computer through the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs are equipped with security features that make it difficult for attackers to replicate and clone the signals that they transmit. These include pseudo-random sequence generators that generate a new unlock code each time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most instances, you can purchase a replacement key fob from the dealer or from another retailer and have it programmed by your locksmith in your car to be compatible with your specific vehicle. This is due to the fact that most of the major US and Asian automobile manufacturers share their key fob programming protocols with third-party companies that create the tools auto locksmiths use to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them since they will likely only work poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you can be certain they'll function properly and be less prone to issues like interfering or not working. This will save you money in the end by avoiding costly repairs or replacing your fobs.
Tool for programming the vehicle manufacturers
Automotive technologies have progressed a lot and today's vehicles need computers to function. Transponder chips are an essential component of this technology.

The cost of the car key fob can vary dependent on the type and model of key, but it is usually between $85 and $400. This includes the labor cost to program the keyfob, as well as any replacement parts.
The car key fobs are more intricate because they use software that interacts with the onboard computer of the car. The software prevents unauthorised access by only permitting keys that have been programmed for a specific car to work. If you decide to replace your keys, you will have to program the new key fob into the car to allow it to function.
This is done by using a programming tool for keys for cars that are compatible with the brand of your vehicle. This tool allows locksmiths to connect to the OBD port in the vehicle and then enter the programming mode. The key programming tool could be a simple handheld device or a fancy one that can do many things that go beyond key programming (like reading and cloning Eeprom files within the ECU).
Although some people might attempt to program their own keys using these tools, this is an activity best left to an experienced auto locksmith. If you're not familiar with the aspects of the various software systems, it's easy to accidentally change settings that could potentially damage the vehicle.

You can also program new keys with EEPROM. It is more complicated and requires a deep understanding of electronic systems. It is best to delegate it to a professional who has expertise with these systems.
Locksmiths can program keys quickly using onboard programming. When everything is done correctly it could take as little as one minute. If the key isn't in the right condition or the procedure isn't followed exactly, the process could be as long as half an hour.
There programming car key are many key programmer scanners on the market that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they cover a wide range of vehicles. However, neither can program every vehicle in existence.
