Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the model and manufacturer the process could be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are found in many newer cars to prevent car theft. These are tiny computer microchips which emit radio signals of low-level. The microchips are equipped with an unique serial number that authenticates your key when you connect it to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money since they don't have to replace their vehicles.
The principle of the transponder system is to make it difficult for thieves to start your car without the right key. In the past, thieves would force your car's ignition switch into the "on" position with a flat screwdriver or even use hot wires to disable the system completely. Transponder chips have drastically reduced the number of thefts.
When you place the transponder key into the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The car's computer onboard will recognise that the key is genuine and allow the fuel to flow, then power the starter or begin 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 appropriate equipment to program your car's keys and remotes.
A good automotive locksmith will possess a multi-vehicle programing device which can be used with different automobile models and manufacturers. This is a much cheaper option than buying specific tools for each model of vehicle. They are not as common, but there are specialised automotive key programmers that can only work on a specific brand of vehicle. The most reliable automotive locksmiths will have the appropriate equipment to tackle any type of vehicle, so ensure you find a reputable company that offers these types of tools.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to open doors and start the engine with the push of a button ignition. They also have buttons that you can press to activate features like trunk release, door locks or control of the fuel flap. Some fobs also have additional functions that can be controlled with the push of a button like a "smart" key fob that lets you summon your car into parking spaces that are difficult to access similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help of a user guide, but you'll need to contact an automotive locksmith if the one you have isn't functioning. This is because a professional locksmith has the right equipment and access to the tools for programming needed to connect your car's computer through the on-board diagnostics (OBD) port beneath the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to clone and replicate the signals that they transmit. Some key fobs have pseudo-random code generators, which generate a new 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 buy the replacement keyfob at an auto dealer or other retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that create the tools used by locksmiths for programming their customer's keys.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, automotive locksmiths strongly discourage using them as they are likely to work poorly or not work at all. Instead, they suggest purchasing fobs specifically designed for your vehicle so that you are certain they'll work properly and are less susceptible to issues such as interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.
Toolkits for Programming Vehicles of Manufacturers
The automotive industry has advanced considerably and today's vehicles need computer technology in order to function. Transponder chips are an essential component of this technology. It needs to be programmed by a locksmith, mechanic or dealer to function. Key fobs are fitted with security features to prevent hot-wiring like in a movie. The car won't start if the keys are not correct.
Key fobs are more complex than the traditional mechanical key and are the reason you'll usually find them in the hands of a skilled, professional auto locksmith. The cost of the car key fob is according to the type and model of key, but it is usually between $85 and $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 complicated because they utilize a software system that works with the computer onboard of the car. The software blocks unauthorized access by only permitting the key to function only if it's been programmed for the specific car. This means that if your keys replaced, you'll have to have the new key fob programmed to the car for it to work.
This is accomplished by using a programing tool for car keys that is compatible with the brand of your vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle and then enter programming mode. The key programming tool could be a handheld device that is inexpensive device or a more expensive one that is capable of performing a wide range of things beyond just key programming (like reading and cloning the eeprom files in the ECU).
Some people attempt to program their keys on their own using these tools. However this should be left to a professional auto locksmith. It is easy to make mistakes when using software systems if you don't understand the nuances. 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 car is older than it could still be equipped with a key made of steel that you can use to open doors and turn off the ignition. Modern vehicles have transponders that need to be acknowledged and accepted by the computer system to start. This is an additional layer of security that prevents thieves from starting and then driving off with a stolen car. A licensed locksmith has the tools and software to create a key that is compatible with the security system in your car.
Your locksmith will have to acquire a blank key compatible with your vehicle's model and make. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will place the car into a special programming mode that allows the locksmith to add a new key to the system.
To do this, the key programming scanner will communicate with the car's computer to send an exact code. The computer will detect this code and add it to the list of approved key. In certain situations scanners can remove keys that have been stolen or lost.
You can also program new keys with EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it's best left to a professional who has extensive experience working on these types of systems.
Onboard programming is the most efficient method for locksmiths to program the new key. If everything is done properly it can take program a car key just one minute. However, if the key isn't placed in the proper condition or the procedure is not adhered to, it could take up to an hour.
There are numerous key programmer scanners on the market that support different car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their wide selection of models for vehicles. There is no system that can program every vehicle. These devices are also expensive. It is best to buy one that will receive regular updates from the manufacturer whenever new technologies are introduced. Your programming machine will quickly become obsolete if you don't take this step.
