Modern automobiles require some kind of key programming. Depending on the car's maker and model, the process could be as simple as onboard programming with a spare working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips which emit low-level radio waves. car key programmer have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proved to be an incredible success in preventing auto theft. It also saves many car owners a significant amount of money because they don't need to replace their vehicles.
The transponder system's basic idea is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, car thieves used an ordinary screwdriver to force the ignition switch of your car into the "on" mode, or hot-wire it in order to evade the system. These kinds of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits the signal which is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will recognize that the key is valid and allow fuel to flow, turn the starter or start it.
Certain vehicles only recognize a certain type of transponder chip, depending on the manufacturer. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
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 much cheaper option than buying separate tools for each type of vehicle. There are also specific key programming tools for automobiles that can only be used on specific brands of vehicles however, they are less popular. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you select an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to unlock doors and start the engine using the push of a button. You can also press buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Some fobs can be controlled using buttons. For instance an "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the assistance of an instruction manual, however you will need to call an automotive locksmith if yours isn't working. This is because a professional locksmith has the equipment that is specialized and access to the tools for programming needed to connect your car's computer through the OBD (OBD) port located beneath the steering wheel.
The majority of 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 different unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase an alternative keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is due to the fact that most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party companies who produce the tools auto locksmiths use to programme keys for their customers.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them because they're likely to work poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle, so that you can be sure they'll work properly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools
Automotive technology has progressed a lot and modern vehicles require computer technology in order to function. One key element 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 built-in security features that stop hot-wiring (like in a film) and the car won't start if it doesn't have the correct key.
These key fobs are more complicated than a 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 will vary based on the vehicle model and the type of key however they usually cost between $85 and $400. This includes the labor required to program the key fob, as well as the costs for any necessary replacement parts.
To make the process more complicated the car key fobs use a special software system to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys programmed for a specific vehicle to function. If you decide to replace your keys, you'll have to program the new key fob to the car in order for it to function.
The most popular method to accomplish this is using the car key programming tool that is compatible with the brand of the vehicle. This tool permits a locksmith to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming tool could be a handheld device that is inexpensive device or a high-end one that is capable of performing various things beyond just key programming (like reading and cloning Eeprom files within the ECU).

Although some people might attempt to program their own keys using these tools, it's something best left to an experienced auto locksmith. If you're not familiar with the ins and outs of the various software systems, it's easy to accidentally change settings that could damage the vehicle. It's important to keep in mind that a knowledgeable professional can assist you in avoiding these issues.
On-Board programming
If your vehicle is of a certain age, you'll still have a traditional key made of metal that you can use to open the doors and turn off the ignition. Modern vehicles have transponders that need to be acknowledged and accepted by the computer system in order to start. This adds another layer of security that prevents car thieves from starting and driving away with a stolen vehicle. A certified locksmith will have the necessary tools and software to create a key that works with the security system of your vehicle.
Your locksmith will first need to purchase an uncut key that is compatible with your vehicle's model and make. Once the key is received the locksmith will connect the scanner for programming to your car's diagnostic port. This will put the vehicle into a specific programming mode, which allows the locksmiths to add the key to the system.
The key programmer scanner communicates with the computer of the car to send an electronic code. The computer will recognize the code and add it to the list of keys that are approved. In some instances the scanner will be able to delete keys that are stolen or lost from the system.
You can also program new keys with EEPROM. It is more complicated and requires a deep understanding of electronic systems. It is best to leave it to a professional who has knowledge of these systems.
Locksmiths can program keys quickly using onboard programming. When everything is done correctly it could take just one minute. However, if the key isn't placed in the right state or the procedure isn't followed exactly, it can take as long as a half hour.
There are numerous key programmer scanners that support different car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely well-liked by locksmiths due to the fact that they support a broad range of vehicle models. The system cannot program every vehicle. Furthermore, these systems are quite expensive. It is a good idea to buy a programmer that will get regular updates as the manufacturer releases new technologies. Your computer's programming software will soon become obsolete if you don't do this.
