Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian automakers have a programming protocol that they share with auto tool makers, so they can design hardware or software for automotive locksmiths.
Transponder Chips
The majority of newer cars have transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. The microchips have a unique serial number which authenticates your keys when 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 enormous success in preventing theft of cars. It also saves many car owners a significant amount of money because they don't need to replace their vehicles.
The principle of the transponder system is to make it hard for thieves to get into your vehicle without the correct key. In the past car thieves used the flat screwdriver to push the ignition switch of your car to go into "on" mode or even wire it hot to bypass the system. These types of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it transmits a signal that is detected by a hidden antenna around the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and will allow fuel flow, power the starter or start the engine.
Based on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming tool that can work on many different car manufacturers and models. This is a much more cost-effective approach than purchasing individual tools for each brand of vehicle. There are also specific key programming tools for automobiles that can only be used on one particular brand of vehicle, but these are less common. The best locksmiths for automotive are equipped to work on any vehicle. Be sure to choose an established company that has this type of equipment.
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 using push-button ignition. You can also use the buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Some fobs also have additional functions that can be controlled using the press of a button like the "smart" key fob that lets you get your car to parking spots that are tight, like you would with a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the help of a user manual, you'll often require an auto locksmith to get a new one programmed in case yours stops functioning. A professional is better equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals that they transmit. automotive key programming include pseudo-random generators that generate a new unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In some instances you can purchase an alternative keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party companies who make the tools used by auto locksmiths to program their customer's keys.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, professional locksmiths advise against using them since they're likely to function poorly or not work even work at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less prone to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Toolkits for Programming Vehicles of Manufacturers
Automotive technologies have advanced considerably and modern vehicles require computers to function. A transponder chip is an important part of this technology. It must be programmed by a locksmith mechanic or dealer to function. Key fobs are fitted with security features to prevent hot-wiring, as in a movie. The car won't start if the keys are not correct.
These key fobs are a little more complex than your mechanical keys, which is why you'll usually find them in the hands of an expert, professional auto locksmith. The cost of a key fob can differ based on the vehicle model and the type of key, but they typically run between $85 and $400. This includes the labor required to program the key fob and the cost of any needed replacement parts.
Car key fobs are more intricate due to the fact that they use a software system that works with the onboard computer of the car. The software prevents unauthorized access by allowing the key to function only if it's programmed to the car in question. If you decide to replace your keys, you will have to program the new key fob into the car in order for it to function.
This is done by using a programing tool for keys for cars that are compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. Key programming devices can be an handheld device that is inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom file inside the ECU).
Some people may attempt to program their keys themselves using these tools. However, this is best left to an experienced auto locksmith. If you're not aware of all the ins and outs of the various software systems, it's possible to accidentally alter settings that could cause damage to the vehicle. It's crucial to remember that an experienced professional will assist you in avoiding these issues.
On-Board Programming
If your car is old enough, it may still come with a metal key that you can use to unlock doors and turn the ignition. Modern cars come with transponder chips that need to be recognized by the computer system of the car to begin. This is a further layer of security that prevents car thieves from starting and then driving off with a stolen car. A locksmith certified will have the tools and software required to create a key that will work in your car's system.
Your locksmith will first need to obtain an uncut key that is that is compatible with the vehicle's make and model. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put the vehicle into the mode of programming that allows the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer of the car to send the code. The computer will be able to recognize the code and add it into the list of keys that are approved. In certain instances the scanner may also be able to erase keys that are stolen or lost from the system.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional who has experience with these systems.
Onboard programming is the fastest method for locksmiths to program a new key. It takes as little as one minute if everything is completed correctly. If the key is not in the correct condition or the procedure isn't followed exactly, the process could be as long as half an hour.
There are numerous key programmer scanners that can be used with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their wide selection of vehicle models. However, neither can program every single vehicle that exists. In addition, these machines cost a lot. It is best to buy one that will receive regular updates from the manufacturer when new technologies are released. Your machine for programming will quickly become obsolete if you don't do this.
