Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process could be as simple as onboard programming using an extra working key or as complex as OBD2 or EEPROM programming.
The majority of US and Asian automakers share their programming protocol with auto tool makers, so they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be a huge success in preventing theft of cars. This technology has also helped car owners save a good amount of money as they do not have to buy new vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would use a flat screwdriver to force the ignition switch in your car to go into "on" mode, or hot-wire it to bypass the system. These kinds of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert the transponder keys into the ignition the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to detect the specific frequency of the chip inside the key. The car's onboard computer will then recognize that the key is legitimate and allow fuel to flow, turn the starter or start it.
Certain vehicles only recognize a specific type of transponder chip according to the manufacturer. This is why it's crucial to make sure that your automotive locksmith is equipped to program your car's key and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming tool that works with different models and manufacturers of cars. This is a cheaper option than purchasing specific tools for each type of vehicle. There are also specific key programming devices for automotive that are only suitable for specific brands of vehicles, but these are less frequently used. The top automotive locksmiths have the right equipment to tackle any type of vehicle, so be sure you choose a reputable business with these kinds 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 ignition. You can also use the buttons to activate features such as trunk releases, door locks or control of the fuel flap. Some fobs can be controlled with the press of buttons. For example, a "smart key" which allows you to summon your car to parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the help of a user manual but you'll usually need an automotive locksmith to get a new one programmed if yours stops working. A professional is better equipped to connect the computer of your car via the OBD port under the steering wheel.
Most key fobs today have security features that make it difficult for hackers to duplicate or copy the signals they transmit. They include pseudo-random generators that generate a new unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some instances you can purchase the replacement keyfob at a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is due to the fact that most of the major US and Asian car manufacturers have key fob programming protocols with third-party companies that make the tools that auto locksmiths utilize to program their customers' keys.
Certain key fobs from the aftermarket may be advertised as compatible with any vehicle. However, automotive locksmiths advise against using them since they're more likely to perform poorly or not even work at all. Instead, they recommend purchasing fobs specifically designed for your vehicle, so that you can be sure they'll work properly and are less susceptible to issues like interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing your fobs.
key reprogramming ' Programming Tools
The automotive industry has advanced considerably and today's vehicles need computer technology in order to function. A transponder chip is an essential part of this technology. It must be programmed by a locksmith mechanic or dealer to function. Key fobs with embedded security features that stop 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 keys and are the reason you'll typically find them in the hands of an expert professional auto locksmith. The cost of the car key fob can vary dependent on the model and type of key, but it is usually between $85 to $400. This includes the labor required to program the key fob and the cost of any needed replacement parts.
To complicate the process the car key fobs make use of a special software to connect to the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys programmed for a specific car to function. If you replace your keys, you will have to program the new key fob in the car to allow it to work.
This is done by using a tool for programming car keys that is compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. Key programming tools can be a handheld device that is inexpensive device or a high-end one that is capable of performing a wide range of things beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people might try to program their keys on their own using these tools. However this should be left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's very easy to make a mistake and alter settings that could potentially damage the vehicle. It's crucial to remember that a knowledgeable professional can assist you in avoiding these issues.
On-Board programming
If your vehicle is older than you, you'll still have a traditional metal key that you can use to open the doors and turn over the ignition. Modern vehicles have transponders that must be recognized and accepted by the computer system to start. This adds an extra layer of security that prevents car thieves from starting a car stolen and then driving off with it. A licensed locksmith will have the right tools and software to program a new key that will work with your car's security system.
Your locksmith will have to purchase a blank key that is compatible with the 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 put the vehicle into the mode of programming which will allow the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer in the car to send the code. The computer will be able to recognize the code and add it into the list of keys that are authorized. In some instances the scanner will be able to delete keys that are stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complex and requires a thorough understanding of electronic systems. It is best to leave it to a professional who has experience with these systems.
Locksmiths can program keys quickly with onboard programming. When everything is done correctly it can take just one minute. If the key isn't in proper condition or the procedure isn't strictly followed, it could take up to a half hour.
There are a variety of key programmer scanners which can work with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular with locksmiths since they cover a wide range of vehicle models. However, neither will be able to program every single vehicle that exists. Additionally, these devices are expensive. It is best to buy an instrument that receives regular updates from the manufacturer whenever new technologies are developed. Otherwise, your programming machine will become obsolete quickly.
