Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the model and manufacturer, the process may be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can create hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are found in a variety of newer vehicles to stop theft of cars. These are tiny computer microchips which emit radio waves at a low level. The microchips have an unique serial number that authenticates your key whenever you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has proven to be extremely successful in preventing theft of cars. It has also saved many car owners a lot of money since they don't have to buy new their vehicles.
The principle of the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, car thieves would force the ignition switch of your car into the "on" position with the flat screwdriver, or hot-wire the car to bypass the system altogether. Transponder chips have dramatically reduced these types of thefts.
When you place the transponder key into the ignition the signal is received by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The car's onboard computer will detect that the key is genuine and allow fuel to flow, power the starter or begin it.
Depending on automotive key programming can only recognize the specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive will have a multi-vehicle programming device that can be used on many different models and brands of cars. This is a less expensive alternative to purchasing individual tools for every brand of vehicle. There are also specially-designed key programming devices for automotive that are only suitable for one particular brand of vehicle however they are not as popular. The best automotive locksmiths will have the proper tools to deal with any kind of vehicle, so make sure you choose a reputable business that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to open doors and start the engine using a push button ignition. It is also possible to press buttons to trigger features such as trunk releases, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled using the button presses like a "smart" key fob that lets you get your car into tight parking spots, like you would with the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself with the assistance of an instruction manual, however you'll need to contact an automotive locksmith if yours has stopped functioning. This is because a professional locksmith has the specialized equipment and access to the programming tools required to connect your car's computer through the OBD (OBD) port beneath the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to duplicate and copy the signals they transmit. Some key fobs have pseudo-random code generators that generate a different unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most instances, you can purchase an alternative key fob from the dealership or another retailer and have it programmable by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customers' keys.
Certain aftermarket key fobs can be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths recommend against using them because they're likely to function poorly or even not even work at all. They suggest buying fobs designed specifically for your vehicle so that they function properly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Tool for Programming Vehicle Manufacturers'
The automotive industry has progressed a lot, and today's vehicles require computers to function. One key element of this technology is a transponder chip which must be programmed into the vehicle by an expert 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 will not start if you don't have the right key.
These key fobs are more complex than your traditional mechanical key, which is why they are usually in the hands of a reputable professional auto locksmith. The cost of a key fob will 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 and the costs for any required replacement parts.
To make the process more complicated the car key fobs make use of a special software to connect to the car's onboard computer. The software prevents unauthorised access by only allowing keys programmed for a specific car to work. This means that if you need your keys replaced, you'll have to have the new key fob programed to the car for it to work.
The most common method to do this is by using an auto key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming tool could either be an inexpensive handheld device or a high-end one that is capable of performing various things beyond key programming (like reading and cloning EEEPROM files in the ECU).
While some people may attempt to program their own keys with these tools, this is something best left to a professional auto locksmith. If you're not aware of all the aspects of the various software systems, it's easy to make a mistake and alter settings that could damage the vehicle. The most important thing to remember is that a skilled professional can help you avoid these problems.
On-Board Programming
If your vehicle is older than you, you'll still have a traditional key made of metal to use to unlock the doors and turn on the ignition. Modern vehicles have transponders that must be recognized and accepted by the computer system in order to start. This is a further security measure to prevent thieves from starting and then driving off with a stolen car. A licensed locksmith will have the right tools and software to create a new key that will work with the security system in your car.
The locksmith will need to get an uncut key that is compatible with the model and make of your vehicle. Once the key is received the locksmith will connect the programming scanner to the diagnostic port of your car. This will put your car in a special programming mode, which will allow locksmiths to connect keys to the system.
The key programmer scanner communicates with the computer of the car to send an electronic code. The computer will be able to recognize the code and add it to the list of keys that are authorized. In some instances the scanner will be able to erase lost or stolen keys from the system.
You can also program new keys by using EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program an entirely new key. When everything is done correctly, it can take as little as one minute. However, if the key isn't placed in the right condition or the procedure isn't strictly followed, it could take up to an hour.
There are numerous 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 wide selection of vehicle models. However, no system can program every vehicle on the market. These machines are also quite expensive. It's a good idea purchase a programer that will get regular updates as the manufacturer develops new technologies. If not, your computer will be obsolete in a short time.
