Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the model and make the procedure could be as simple as using an extra key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian car makers have programming protocols that they share with auto tool manufacturers to allow them to develop tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips have a unique serial number which authenticates your key when you connect it 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 a huge success in preventing theft of cars. It also saves many car owners a lot of money as they don't have to replace their vehicles.
The fundamental 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 the flat screwdriver to push the ignition switch of your car to go into "on" mode or even hot-wire it to evade the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys in the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed to read the specific frequency of the chip inside the key. The car's computer onboard will recognize that the key is legitimate and allow fuel to flow, turn up the starter or begin it.
Some vehicles only recognize specific type of transponder chip depending on the manufacturer. This is why it's essential to ensure that your locksmith for automotive has the right equipment to program your vehicle's keys and fobs correctly.
A reliable locksmith for cars will have a multi-vehicle programming device that can be used with different automobile models and manufacturers. This is a much more cost-effective approach than purchasing individual tools for each brand of vehicle. These aren't as popular however, there are specialist automotive key programming tools that can only work on a specific brand of vehicle. The best automotive locksmiths will have the proper tools to work on any type of vehicle, so be sure you find a reputable company that has these types of tools.
Key FOBs
The name implies that key FOBs contain programmable transponder chips that enable your vehicle to identify and unlock the doors, or start the engine using push-button ignition. It is also possible to press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled by pressing buttons. For instance an "smart key" that allows you summon your car to tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from a user guide, but you'll need to call an automotive locksmith if the one you have has stopped functioning. A professional locksmith is more equipped to connect your computer to the vehicle to the OBD port under the steering wheel.
Today, most key fobs include security features that make it difficult for hackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase the replacement keyfob at an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party companies who make the tools used by auto locksmiths to program their customer's keys.
Certain key fobs from the aftermarket may be marketed as being compatible with all vehicles. However, automotive locksmiths advise against using them since they are likely to work poorly or even not at all. Instead, they recommend purchasing fobs specifically designed for your specific vehicle so that you can be sure they'll function properly and be less susceptible to issues like interfering or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Tool for programming the vehicle manufacturers
The automotive industry has made huge strides in the last few decades. Today's vehicles are computer-driven. One of the key components of this technology is a transponder chip which must be programmed into the vehicle by an auto locksmith or dealer/mechanic order to function. Key fobs with embedded security features that will prevent hot-wiring (like in a movie) and the car won't start without the correct key.
Key fobs are more complex than the traditional mechanical key and that's why you'll typically find them in the hands of an expert professional auto locksmith. The cost of a car key fob varies according to the type and model of key, but it is usually between $85 and $400. This includes the labor to program the key fob, as well as the costs for any necessary replacement parts.
To make the process more difficult, these 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 vehicle to function. If you replace your keys, you will need to program the new key fob in the car to allow it to function.
The most common method to accomplish this is using a car key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. Key programming devices can be a handheld device that is affordable or extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
Although some people might attempt to program their own keys with these tools, it's a job best left to an experienced auto locksmith. It is easy to make mistakes using the software systems if you don't understand the intricacies. This could result in damage. The most important thing to keep in mind is that a professional with experience can assist you in avoiding these issues.
On-Board programming
If your car isn't as old that it has a key, it might still come with a metal key that you can use to open doors and turn off the ignition. However, modern vehicles have a transponder chip that must be recognized by the computer system to begin. This is an extra layer of security that stops car thieves from starting a car stolen and driving away with it. A certified locksmith will have the necessary tools and software to create a new key that is compatible with the security system in your car.
Your locksmith will first need to obtain an uncut key that is that is compatible with the vehicle's model and make. Once the key is received the locksmith will connect the scanner for programming to your car's diagnostic port. This will place the car into the mode of programming which will allow the locksmith to add a new key to the system.
The key programmer scanner communicates website with the computer in the vehicle to send the code. The computer will detect this code and include it to the list of keys that are approved. In some cases, a scanner can also remove keys that have been stolen or lost.
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 function. This is why it's best left to a professional who has extensive expertise working on these types of systems.
Locksmiths can program a key quickly using onboard programming. If everything is done correctly it could take just one minute. If the key isn't in the correct state or the procedure is not adhered to, it could take up to a half hour.
There are many key programmer scanners available that can be used with different car models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they can be used with a variety of vehicle models. There is no system that can program every vehicle. These machines are also quite expensive. It's a good idea purchase a computer that will get regular updates as the manufacturer releases new technologies. In the event that your machine is not updated, it will be obsolete in a short time.
