Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can create tools or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips that emit low-level radio waves. They have a unique serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has proven to be extremely successful in preventing car theft. It also saves many car owners a lot of money as they don't have to buy new their vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to start your vehicle without a valid key. In the past, thieves would simply push your ignition switch to the "on" position using an ordinary screwdriver or use hot wires to disable the system entirely. These kinds of thefts have drastically reduced with the introduction of the transponder chip.
When you insert the transponder keys in the ignition, the signal is received by an antenna that is hidden within the barrel. The antenna is programmed with the frequency of the chip in the key. The onboard computer of the car will recognize the key as being valid and will allow fuel flow, power the starter or begin the engine.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. This is why it's important to ensure that your locksmith in the automotive industry has the appropriate equipment to program your vehicle's keys and fobs correctly.
A reputable locksmith for automotive will possess a multi-vehicle programing device which can be used with different automobile models and manufacturers. This is a cheaper solution than buying specific tools for each type of vehicle. They are not as common but there are automotive key programmers that can only work on a specific model of vehicle. The best locksmiths for automotive are equipped to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to unlock doors and start the engine using a push button ignition. It is also possible to press buttons to activate features like trunk locks, door locks or fuel flap controls. Some fobs can be controlled by pressing buttons. For instance, a "smart key" that allows you summon your car to parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you using the help of a user manual but you'll usually need an automotive locksmith to have a new one programmed if yours stops 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 to the on-board diagnostics (OBD) port beneath the steering wheel.
Today, most key fobs include security features that make it difficult for criminals to clone or replicate the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a unique unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy the replacement keyfob at a dealership or another retailer. Your automotive locksmith will then program it to work with your car. This is because most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party companies that create the tools auto locksmiths employ to programme keys for their customers.
Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, professional locksmiths advise against using them since they are likely to work poorly or not even work at all. They suggest purchasing fobs that are designed specifically for your vehicle so that they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers
The automobile industry has made significant advances in the last couple of decades. Today's cars are computer-driven. A transponder chip is an important part of this technology. It must be programmed by a locksmith, mechanic, or dealer to work. Key fobs come with built-in security features that prevent hot-wiring (like in a movie) and the car will not start if you don't have the proper key.
These key fobs are more complex than your traditional mechanical key and are the reason you'll typically find them in the hands of a reputable, professional auto locksmith. The cost of a key fob may vary depending on the car model and the key type however they usually cost between $85 to $400. This includes the labor to program the key fob, as well as the cost of any needed replacement parts.
These car key fobs are more complex because they use an operating system that communicates with the onboard computer of the car. The software blocks access by unauthorised persons by only allowing keys programmed specifically for a particular car to function. This means that if you need your keys replaced, you'll need have the new key fob programed to the car to function.
This is done by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool allows locksmiths to connect to the OBD port on the vehicle and then enter the programming mode. The key programming tool could be a handheld device that programming car keys is inexpensive device or a more expensive one that can do many things beyond just key programming (like reading and cloning the Eeprom files within the ECU).
While some may try to program their own keys with these tools, this is a job best left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to accidentally change settings that could cause damage to the vehicle. It's important to keep in mind that an experienced professional will help you avoid these problems.
On-Board programming
If your vehicle is older than you that you'll have a traditional metal key to use to unlock the doors and turn off the ignition. Modern vehicles have a transponder that must be recognized and accepted by the computer system before it can start. This is an extra layer of protection that can stop car thieves from starting a car stolen and then driving off with the car. A locksmith who is certified will have the right tools and software to program a new key that works with your car's security system.
The locksmith needs to purchase a blank key that is compatible with the make and model of your vehicle. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will put the vehicle into an exclusive programming mode that allows the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the vehicle to send an electronic code. The computer will recognize the code and add it to the list of keys approved by. In some cases, the scanner will also be able to remove lost or stolen keys from the system.
You can also program new keys by using EEPROM. It is more complex and requires a thorough understanding of electronic systems. This is why it's best left to a professional that has extensive expertise working on these types of systems.
Onboard programming is the quickest way for a locksmith to program an entirely new key. It can take as little as a minute when everything is done correctly. If the key is not in good working order or the procedure isn't being followed precisely, the procedure could take up to half an hour.
There are numerous key programmer scanners that can be used with different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their broad range of models for vehicles. The system cannot program every vehicle. In addition, these machines are quite expensive. It's best to purchase an instrument that receives regular updates from the manufacturer when new technologies are released. If not, your computer will become obsolete quickly.
