Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the vehicle's make and model, the procedure could be as simple as onboard programming using a spare key that works or as complicated as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio signals of 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 isn't able to recognize the signal, the engine will be shut down. This technology has proved to be an enormous success in preventing auto theft. It has also saved many car owners a lot of money because they don't need to replace their vehicles.
The principle behind the transponder system is to make it impossible for thieves to get into your car without the proper key. In the past car thieves used the flat screwdriver to push the ignition switch of your car into the "on" mode or even hot-wire it in order to evade the system. These types of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it will transmit the signal which is received by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow and power the starter to start the engine.
Depending on the manufacturer some vehicles will only recognise the specific type of transponder chip. This is why it's essential to ensure that your automotive locksmith is equipped to program your vehicle's keys and fobs properly.
A reputable locksmith for cars should have a multi-vehicle key programming tool that is compatible with different models and manufacturers of cars. This is a cheaper option than buying individual tools for each brand of vehicle. There are also specific key programming devices for automotive that can only be used on specific brands of vehicles, but these are less frequently used. The best automotive locksmiths will have the appropriate tools to deal with any kind of vehicle, so be sure you find a reputable company that has these types of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and begin the engine with the push of a button. You can also use the buttons to activate features like trunk releases, door locks or fuel flap controls. Some fobs can be controlled with the press of buttons. For example, a "smart key" that lets you call your car to parking spaces, like a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual, you'll often require an auto locksmith to have a new one programmed if yours stops working. This is because a professional locksmith has the equipment that is specialized and access to the programming tools required to connect your car's computer to the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs today include security features that make it difficult for criminals to duplicate or copy the signals they transmit. Certain key fobs come with pseudo-random code generators which generate a different unlock code each time you press the button. This prevents attackers capturing and playing back the unlock signal to gain access to your vehicle.
In some instances you can purchase an alternative keyfob from an authorized dealer or another retailer. The locksmith you choose to use will then program it to work with your vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party companies who produce the tools used by locksmiths who program their customers' keys.
Certain aftermarket key fobs can be marketed as compatible with any vehicle. However, professional locksmiths recommend against using them because they're more likely to perform poorly or not work at all. Instead, they suggest purchasing fobs that are specifically made 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 over the long term by avoiding expensive repairs or replacing the fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have progressed a lot and modern vehicles require computer technology to function. One key element of this technology is a transponder chip that requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to function. These key fobs are equipped with security features to prevent hot-wiring, as in a film. The car won't start without the correct keys.
These key fobs are a little more complex than your traditional mechanical key and are the reason you'll typically find them in the hands of an expert professional auto locksmith. The cost of a car key fob varies dependent on the type and model of key, but is typically between $85 to $400. This includes the cost of labor to program the key fob, as well as the cost of any needed replacement parts.
Car key fobs are more complex because they utilize software that interacts with the computer onboard of the car. The software prevents key programer unauthorised access by only permitting keys that have been programmed specifically for a particular car to work. This means that if you need your keys replaced, you'll have to have the new key fob programmed to the car in order for it to function.
The most common method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter an programming mode. The key programming device can be a handheld device that's affordable or sophisticated and capable of doing more than just program keys (like reading the eeprom file inside the ECU).
Some people try to program their keys by themselves using these tools. However, this is best left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's possible to make a mistake and alter settings that could potentially damage the vehicle. The most important thing to keep in mind is that a professional with experience can assist you in avoiding these problems.
On-Board Programming
If your vehicle is old enough, you'll still have a traditional metal key to open the doors and turn off the ignition. Modern cars come with transponders that must be recognized and accepted by the computer system before it can start. This adds an extra layer of protection that can stop car thieves from starting a stolen car and driving off with it. A certified locksmith will have the necessary tools and software to create a key that is compatible with the security system of your vehicle.
Your locksmith will need to purchase a blank key that is compatible with your car's model and make. Once the key is in your possession, your locksmith will link the scanner for programming to your car's diagnostic port. This will put your car in a special programming mode, which will allow locksmiths to add a key to the system.
The key scanner that is programmed communicates with the computer of the car to send the code. The computer will be able to recognize the code and add it to the list of keys that are approved. In some cases, the scanner will also be able to delete keys that have been stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complicated and requires a deep understanding of how electronic systems function. It is best to delegate it to a professional who has experience with these systems.
Locksmiths can program keys quickly by using onboard programming. If everything is done correctly, it can take as little as one minute. If the key isn't in good working order or the procedure isn't followed precisely, the procedure could be as long as half an hour.
There are many key programmer scanners available that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they can be used with a variety of vehicles. However, no system can program every single vehicle that exists. In addition, these machines cost a lot. It's best to purchase one that will receive regular updates from the manufacturer whenever new technologies are released. Your computer's programming software will soon become obsolete if you don't take this step.
