Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Depending on your vehicle's model and make the procedure could be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car makers have programming protocols that they share with auto tool manufacturers to allow them to develop software and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are found in many newer cars to stop theft of cars. These are tiny computer microchips which emit radio waves at a low level. The microchips have a unique serial number which authenticates your keys when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has been a huge success in preventing theft of cars. It has also saved many car owners a significant amount of money since they don't have to replace their 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 would use an ordinary screwdriver to force the ignition switch in your car into "on" mode, or hot-wire it in order to get around the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it transmits the signal which is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip inside the key. The car's onboard computer will then recognise that the key is valid and allow fuel to flow, turn the starter or begin it.
Some vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that works with different models and manufacturers of cars. This is a far cheaper option than buying separate tools for each type of vehicle. These are less common but there are automotive key programmers that can only work on a particular model of vehicle. The best automotive locksmiths will have the right tools to deal with any kind of vehicle, so make sure you find a reputable company with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and begin the engine with a push button ignition. They also have buttons you can press to activate features like trunk release, door locks or fuel flap control. Certain fobs can be controlled using buttons. For instance, a "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the help of a user manual however, you'll typically need an automotive locksmith to have a new one programmed if the one you have isn't functioning. A professional locksmith is better equipped to connect your computer to the vehicle to the OBD port under the steering wheel.
Most key fobs today come with security features that make it difficult for hackers to duplicate or duplicate the signals they transmit. Certain key fobs come with pseudo-random code generators which generate a unique unlock code each time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In many instances you can buy an additional key fob at the dealership or another retailer and then have it programmed by your automotive locksmith to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that make the tools used by auto locksmiths to program their customer's keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive do not 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 can be certain they'll function correctly and are less prone to issues such as interfering or not working. This will save you money over time by avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tool

It has to be programmed by a locksmith mechanic or dealer to function. Key fobs with embedded security features that will prevent hot-wiring (like in a movie) and the car won't start without the correct key.
These key fobs can be a little more complex than a standard mechanical key. This is why they are usually in the hands of seasoned, professional auto locksmiths. The cost of a car key fob varies depending on the model and type of key, but it is generally between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
To complicate the process to make the process more complicated, these key fobs for cars make use of a special software to connect to the car's onboard computer. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific car to function. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car in order to function.
This is done by using a tool for programming keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming device could be an handheld device that is inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom files in the ECU).
While some may try to program their own keys with these tools, this is something best left to a professional auto locksmith. It is easy to make mistakes with the software systems if you aren't aware of the nuances. This could lead to damage. It's important to remember that a knowledgeable professional can help you avoid these problems.
On-Board Programming

This will put the vehicle into a special programming mode that allows the locksmith to add a new key into the system.
The key programmer scanner communicates with the computer in the car to send an electronic code. The computer will recognize the code and add it into the list of keys that are authorized. In some cases the scanner will be able to erase keys that are stolen or lost from the system.
You can also program new keys by using EEPROM. resource for this article is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional who has knowledge of these systems.
Locksmiths can program keys quickly with onboard programming. If everything is done correctly, it can take as little as one minute. If the key isn't in the right condition or the procedure isn't being followed exactly, the process could take as long as a half hour.
There are a variety of key programmer scanners which can work with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their broad range of models for vehicles. The system cannot program every vehicle. In addition, these machines cost a lot. It is a good idea to buy a programmer that receives regular updates as the manufacturer releases new technologies.
