Automotive Locksmith Key Programming
Modern cars need some type of key programming. Depending on the model and manufacturer the procedure could be as simple as using a spare key to programme the computer onboard, or as complex as OBD2 programming or EEPROM.
Most US and Asian car manufacturers 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 used in a lot of modern cars 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 vehicle when it is connected to the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proven to be an incredible success in preventing auto theft. It has also saved many car owners a significant amount of money since they don't need to replace their vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, thieves would simply push the ignition switch of your car into the "on" position using an ordinary screwdriver or hot-wire the car to bypass the system entirely. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it transmits a signal that is picked up by a hidden antenna around the barrel of the ignition. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow, power the starter or start the engine.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the right equipment to program your car's keys and fobs properly.
A reputable locksmith for cars should have a multi-vehicle key programming tool that is compatible with different models and manufacturers of cars. This is a far more cost-effective approach than purchasing individual tools for each brand of vehicle. They are not as common however, there are specialist automotive key programmers that can only work on a particular brand of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose an established company that has this type of equipment.
Key FOBs
As the name suggests, key FOBs contain transponder chips that can be programmed to allow your car to recognize and unlock the doors or start the engine using a push button ignition. They also have buttons you can press to trigger features like door locks, trunk release or fuel flap control. Some fobs have additional functions that can be controlled using the push of a button for example, a "smart" key fob that lets you bring your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help from the user guide, however you will need to call an automotive locksmith if yours has stopped working. A professional is better equipped to connect your computer to the car via the OBD port under the steering wheel.
The majority of key fobs today come with security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code every time you press the key fob's button. This prevents attackers capturing and replaying the unlock signal to gain access to your vehicle.
In many cases you can purchase an alternative key fob from the dealer or other retailer and have it programmable by your automotive locksmith to fit your particular vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party firms who create the tools used by auto locksmiths to program their customers' keys.
Although car key programming from the aftermarket are marketed as being compatible with all vehicles, most automotive locksmiths don't recommend using them because they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they work correctly and are less prone to issues like interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.
Tool for programming the vehicle manufacturers
The automotive industry has made huge strides in the last few decades. Today's vehicles are computer-driven. One key element of this technology is a transponder chip that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs with embedded security features that stop hot-wiring (like in a movie) and the car won't start without the proper key.
Key fobs are a little more complex than the traditional mechanical key and that's why they are usually in the hands of an expert, professional auto locksmith. The cost of a car key fob varies dependent on the model and type of key, but is typically between $85 to $400. This includes the cost of labor to program the key fob as well as the costs for any necessary replacement parts.
To complicate the process the car key fobs make use of a special software to connect to the car's onboard computer. The software prevents unauthorized access by allowing the key to function only if it's programmed to the car in question. This means that if your keys replaced, you'll need to have the new key fob programmed to the car for it to function.
The most common method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port on the vehicle, and then enter the programming mode. Key programming tools can be a handheld device that is inexpensive device or a fancy one that can do various things that go beyond key programming (like reading and cloning EEEPROM files in the ECU).
Some people may attempt to program their keys by themselves using these tools. However it's best to leave this task to an expert auto locksmith. It's easy to make a mistake when using software systems if you don't understand the intricacies. This could lead to damage. The most important thing to keep in mind is that a skilled professional can help you avoid these problems.
On-Board Programming
If your car is older than that it has a key, it might still come with a key made of steel that you can use to open doors and turn off the ignition. However, modern vehicles have transponder chips that need to be recognized by the computer system to begin. This is an extra layer of protection that can stop car thieves from stealing a car and then driving off with it. A locksmith certified has the tools and software required to program a key that can function in your car's system.
The locksmith will require an uncut key that is compatible with the make and model of your car. Once the key is in your possession the locksmith will connect the scanner for programming to the diagnostic port of your car. This will put your car into an exclusive programming mode that allows the locksmith to add a new key into the system.

The key scanner is programmed to communicate with the computer of the vehicle to send the code. The computer will detect this code and include it into the list of keys that are authorized. In certain situations scanners can erase keys that were stolen or lost.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complicated and requires a thorough understanding of how electronic systems operate. It is best to delegate it to a professional who has experience with these systems.
Locksmiths can program a key quickly using onboard programming. If everything is done properly, it can take just one minute. If the key isn't in the correct condition or the procedure isn't followed exactly, the process can take up to half an hour.
There are a variety of key programmer scanners that work with various vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they support a broad range of vehicles. However, no system can program every single vehicle that exists. In addition, these machines are expensive. It is a good idea to buy a programmer that receives regular updates when the manufacturer introduces new technologies. Otherwise, your programming machine will become obsolete quickly.
