Automotive Locksmith Key Programming
The majority of modern cars require some kind of key programming. Depending on the model and make, the process may be as simple as using an additional key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers share their programming protocols with auto tool manufacturers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips have an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has been an incredible success in preventing auto theft. It also saves many car owners a lot of money as they don't need to replace their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to open the doors of your car without the right key. In the past, thieves used the flat screwdriver to push the ignition switch in your car to go into "on" mode, or hot-wire it in order to evade the system. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder keys into the ignition, it will transmit an electrical signal that is received 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 onboard computer in the car will recognize the key as being valid and allow fuel flow, power the starter or start the engine.
Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. It is therefore important that your locksmith in the automotive industry is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reliable locksmith for cars will have a multi-vehicle programming device that can be used with different car models and manufacturers. This is a less expensive 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 work on a specific brand of vehicle. The best automotive locksmiths will have the proper equipment to tackle any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and begin the engine with the push of a button. You can also press buttons to trigger features such as trunk locks, door locks or fuel flap controls. Some fobs also have additional functions that can be controlled with the button presses like the "smart" key fob that allows you to bring your car into parking spaces that are difficult to access similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
While some replacement keys can be programmed with the aid of a user's guide, you'll often need an automotive locksmith to have a new one programmed if yours stops functioning. A professional locksmith is better equipped to connect your computer to the car via the OBD port on the steering wheel.
The majority of key fobs come with security features that make it difficult for attackers to clone and replicate the signals that they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code each 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 some instances you can purchase the replacement keyfob at 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 makers have key fob programming protocols with third-party companies that produce the tools locksmiths for auto employ to program their customers' keys.
Certain aftermarket key fobs can be advertised as being compatible with all vehicles. However, automotive locksmiths advise against using them since they're more likely to perform poorly or not work even work at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they function properly and are less prone to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements for your fobs.

The automotive industry has advanced considerably and modern vehicles require computer technology to function. One of the key components of this technology is a transponder chip which must be programmed into the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs come with security features to prevent hot-wiring, like in a film. The car won't start if the keys are not correct.
These key fobs are a little more complex than the traditional mechanical keys, which is why you'll usually find them in the hands of a skilled professional auto locksmith. The cost of a car key fob varies depending on the type and model of key, but is usually between $85 and $400. This includes the labor to program the key fob as well as the costs for any required replacement parts.
Car key fobs are more complex because they utilize software that interacts with the onboard computer of the car. The software prevents unauthorized access by permitting the key to function only if it's been programmed to that specific car. If you change your keys, you'll need to program the new key fob in the car to allow it to function.
The most common method to do this is by using the car key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. The key programming device could be an handheld device that is inexpensive or one that is extravagant and can do more than just programming keys (like reading the eeprom files in the ECU).
While some people may attempt to program their own keys with these tools, it's something best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's possible to accidentally alter settings that could cause damage to the vehicle. The most important thing to remember is that an experienced professional can help you avoid these issues.

You can also program new keys using EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it's best left to a professional who has a lot of experience working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program a new key. When everything is done correctly, it can take just one minute. If the key is not in the correct condition or the procedure isn't being followed exactly, the process can take as long as a half hour.
There are numerous key programmer scanners on the market that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their broad range of vehicle models.
