Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on your vehicle's model and make the process could be as simple as using a spare key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
Most US and Asian car makers use the same programming protocols as auto tool manufacturers to allow them to develop software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are used in a lot of modern cars to stop theft of cars. These are tiny computer microchips that emit low-level radio signals. 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 does not recognize the signal, the engine will be shut down. This technology has proven to be an incredible success in preventing auto theft. It also saves many car owners a lot of money because they don't have to replace their vehicles.
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 used an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode or even wire it hot to evade the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip in the key. The car's onboard computer will then recognise that the key is legitimate and allow the fuel to flow, then power the starter or begin it.
Some vehicles only recognize specific type of transponder chip depending on the manufacturer. This is why it's important to ensure that your locksmith for automotive is equipped to program your car's key and fobs correctly.
A reputable locksmith for cars should have a multi-vehicle key programming device that is compatible with different models and manufacturers of cars. This is a more cost-effective alternative to purchasing individual tools for every brand of vehicle. They are not as common however, there are specialist automotive key programmers that can only work on a specific type of vehicle. The top automotive locksmiths have the right tools to deal with any kind of vehicle, so ensure you choose a reputable firm that offers these types of tools.
Key FOBs
As the name implies, key FOBs contain transponder chips programmable that allow your vehicle to recognize and open the doors or start the engine with a push-button ignition. There are also buttons that you can push to activate features like door locks, trunk release or control of the fuel flap. Some fobs can be controlled by pressing buttons. For example the "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help of a user guide, but you'll need to contact an automotive locksmith in the event that yours has stopped functioning. This is because a professional locksmith has the right equipment and access to the programming tools required to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
Today, most key fobs come with security features that make it difficult for attackers to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a unique unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some instances, you can buy an alternative keyfob from an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of the major US and Asian automobile manufacturers have key fob programming protocols with third-party companies who make the tools that locksmiths for auto employ to programme keys for their customers.
While some aftermarket key fobs are advertised as compatible with any vehicle However, the majority of locksmiths in the automotive industry don't recommend using them because they will likely only work poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle so that you are certain they'll work properly and are less prone to issues such as interfering or not working. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.

Key fobs come with security features to prevent hot-wiring like in a movie. The car will not start if the keys are not correct.
These key fobs are a bit more complicated than a traditional mechanical key, which is why you'll typically find them in the hands of an expert, professional auto locksmith. The cost of a key fob can vary based on the vehicle model and the key type, but they typically run between $85 to $400. This includes the labor to program the key fob as well as the cost of any needed replacement parts.
These car key fobs are more complex because they use software that interacts with the computer onboard of the car. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific vehicle to work. If you decide to replace your keys, programming car keys you will need to program the new key fob into the car to allow it to function.
The most popular method to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter an programming mode. Key programming devices can be a handheld device that's inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom file inside the ECU).
Some people may try to program their keys themselves using these tools. However it's best to leave this task to an expert auto locksmith. Unless you're familiar with all the details of the various software systems, it's possible to accidentally alter settings that could cause damage to the vehicle.

The key scanner that is programmed communicates with the computer of the vehicle to send a code. The computer will recognize the code and add it into the list of keys that are approved. In certain situations scanners can erase keys that were stolen or lost.
You can also program new keys with the EEPROM. It is more complicated and requires a thorough understanding of how electronic systems function. It is best to delegate it to a professional with expertise with these systems.
Locksmiths can program keys quickly with onboard programming. When everything is done correctly, it can take just one minute. If the key isn't in good working order or the procedure isn't followed exactly, the process can take up to half an hour.
There are numerous key programmer scanners that can be used with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of vehicle models. There is no system that can program every vehicle. Furthermore, these systems are quite expensive. It is a good idea to purchase a programer that is updated regularly when the manufacturer introduces new technologies. Otherwise, your programming machine will be obsolete in a short time.
