Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and make, the process may be as simple as using a spare key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are found in many newer cars to stop theft of cars. These are tiny computer microchips which emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has proved to be an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money because they don't have to buy new their vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to start your car without a key. In the past car thieves used an ordinary screwdriver to force the ignition switch in your car into the "on" mode, or hot-wire it in order to bypass the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will send an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. 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 valid and allow fuel to flow, power up the starter, or even start it.
Some vehicles only recognize specific type of transponder chip, depending on the manufacturer. Therefore, it is essential that your locksmith in the automotive industry is equipped with the right equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have a multi-vehicle key programming tool that works with different models and car brands. This is a much cheaper alternative than buying individual tools for each brand of vehicle. There are also specially-designed automotive key programmer devices that can only be used on specific brands of vehicles, but these are less common. The top automotive locksmiths have the appropriate tools to work on any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
The key FOBs are programmable transponder chips that allow your vehicle to open doors and start the engine with the push of a button. They also have buttons that you can press to trigger features such as door locks, trunk release or control of the fuel flap. Certain fobs can be controlled by pressing buttons. For example, a "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the assistance of a user's manual, you'll often need an automotive locksmith to have a new one programmed if yours stops working. This is because a professional locksmith has the right equipment and access to the programming tools required to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to replicate and clone the signals they transmit. Some key fobs have pseudo-random code generators that generate a different unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many cases you can buy an alternative key fob from the dealership or another retailer and have it programmable by a locksmith for your vehicle to work with your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that produce the tools used by locksmiths for programming their customers' keys.
While some aftermarket key fobs are advertised as compatible with all vehicles, most automotive locksmiths don't recommend using them because they are likely to function poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your specific vehicle so that you can be sure they'll function properly and be less prone to issues such as interference or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have advanced considerably and modern vehicles require computer technology in order to function. One key element of this technology is a transponder chipset that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs with embedded security features that will prevent hot-wiring (like in a film) and the car will not start if you don't have the right key.
Key fobs are more complex than your traditional mechanical keys and that's why you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
Car key fobs are more complex due to the fact that they use an operating system that communicates with the computer onboard of the car. The software blocks access to unauthorized users by allowing the key to operate only if it's programmed to the car in question. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car in order for it to work.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter the programming mode. The key programming device could be a handheld device that is inexpensive or one that is sophisticated and capable of doing more than just programming keys (like reading the eeprom file in the ECU).
While some people may attempt to program their own keys using these tools, this is something best left to an experienced auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's easy to accidentally alter settings that could cause damage to the vehicle. The most important thing to remember is that a professional with experience can assist you in avoiding these issues.
On-Board programming
If your car is old enough it could still be equipped with a key made of metal that can be used to open doors and turn on the ignition. However, car key programming have a transponder chip that must be recognized by the car's computer system in order to start. This adds an extra layer of protection that can stop car thieves from starting a car stolen and driving off with it. A locksmith who is certified will have the right tools and software to create a new key that works with your car's security system.
Your locksmith will need to purchase a blank key that is compatible with the vehicle's model and make. Once the key is in hand the locksmith will connect the programming scanner to the diagnostic port of your car. This will put the vehicle into an exclusive programming mode that will allow the locksmith to add a new key into the system.
The key scanner is programmed to communicate with the computer in the vehicle to transmit an electronic code. The computer will recognize the code and add it to the list of keys that are approved. In certain instances the scanner will be able to remove lost or stolen keys from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires an in-depth understanding of how electronic systems work. This is why it should be left to a professional who has years of expertise working on these types of systems.
Onboard programming is the quickest method for locksmiths to program a new key. It takes as little as a minute when everything is executed correctly. If the key is not in the correct condition or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are a variety of key programmer scanners on the market that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they cover a wide range of vehicle models. No system can program every vehicle. These devices are also expensive. It is a good idea to purchase a computer that is updated regularly when the manufacturer introduces new technologies. In the event that your machine is not updated, it will soon become obsolete.
