Automotive Locksmith Key Programming
Most modern-day cars require some type of key programming. Depending on the car's maker and model, the procedure could be as simple as programming onboard using a spare key that works or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can develop software or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has proven to be extremely successful in preventing theft of cars. This technology has also saved car owners a great deal of money as they do not have to buy new vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without a key. In the past, thieves would force the ignition switch of your car into the "on" position using the flat screwdriver, or make use of hot-wires to bypass the system completely. Transponder chips have dramatically reduced the number of thefts.
When you place the transponder key in the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will then recognize that the key is genuine and allow fuel to flow, power the starter or start it.
Depending on the manufacturer certain vehicles can only accept a specific type of transponder chip. It is therefore important that your locksmith in the automotive industry is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming device that works with different models and car brands. This is a far cheaper alternative than buying specific tools for each model of vehicle. These are less common however, there are specialist automotive key programming tools that can only be used on a specific type of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Be sure to choose a reputable firm that has this type of equipment.
Key FOBs
As the name implies, key FOBs are home to the programmable transponder chips that allow your vehicle to identify and unlock the doors, or start the engine using a push button ignition. You can also press buttons to activate features such as trunk releases, door locks or fuel flap controls. Certain fobs can be controlled using buttons. For example an "smart key" that lets you call your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the aid of a user's guide but you'll usually 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.
Today, most key fobs come with security features that make it difficult for criminals to clone or replicate the signals they transmit. Certain key fobs feature pseudo-random code generators which generate a different unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In certain instances you can purchase an alternative keyfob from an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because most of the major US and Asian automobile manufacturers use key fob programming protocols with third-party companies who create the tools locksmiths utilize to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles 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. They recommend buying fobs made specifically for your vehicle to ensure they function properly and are less susceptible to issues read more like interference or incompatibility. This will save money in the long run by avoiding costly repairs or replacements for your fobs.
Tool for programming the vehicle manufacturers
Automotive technology has advanced considerably and today's vehicles need computers to function. A transponder chip is an important part of this technology. It needs to be programmed by a locksmith, mechanic, or dealer to work. Key fobs are fitted with security features to stop hot-wiring, as in a movie. The car will not start if the keys are not correct.
Key fobs are a little more complicated than a traditional mechanical keys and that's why they are usually in the hands of a reputable professional auto locksmith. The cost of a car key fob varies depending on the type and model of key, but is usually 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.
These car key fobs are more intricate due to the fact that they use an operating system that communicates with the computer onboard of the car. The software prevents unauthorized access by allowing the key to function only if it's been programmed for the specific car. This means that if you need your keys replaced, you'll need to have the new key fob programed to the car to function.
This is accomplished by using a programming tool for keys for cars that are compatible with the brand of your vehicle. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming device can be an handheld device that is affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).
Some people may try to program their keys on their own using these tools. However this should be left to a professional auto locksmith. It's easy to make mistakes when using software systems if you don't understand the intricacies. This can lead to damage. It's important to remember that a professional with experience will help you avoid these issues.
On-Board Programming
If your vehicle is older than you that you'll have a traditional metal key to open the doors and turn on the ignition. Modern cars come with a transponder that must be recognized and accepted by the computer system to start. This is an additional layer of security that prevents thieves from starting and driving away with a stolen car. A locksmith certified has the tools and software necessary to program a key that can be compatible with your car's security system.
Your locksmith will first need to obtain a blank key that is compatible with your car's make and model. Once the key is received, your locksmith will link the programming scanner to your car's diagnostic port. This will put your car into an exclusive programming mode that will allow the locksmith to add a new key to the system.
To do this, the key programmer scanner will communicate with the car's computer to send an exact code. The computer will recognize the code and add it to the list of approved keys. In some instances 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 complex and requires a thorough understanding of how electronic systems function. It is best to leave it to a professional who has knowledge of these systems.
Locksmiths can program a key quickly with onboard programming. It takes as little as an hour if everything is done correctly. If the key isn't placed in the proper state or the procedure isn't adhered to, it could take as long as a half hour.
There are a variety of key programmer scanners on the market that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their broad range of models for vehicles. However, neither can be programmed for every vehicle on the market. These machines are also quite expensive. It's best to purchase an instrument that receives regular updates from the manufacturer as new technologies are released. Your programming machine will quickly become obsolete if you don't do this.
