Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Based on the model and manufacturer, the process may be as simple as using an additional key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to guard against theft of vehicles. These are microchips in the form of computers that emit low-level radio signals. The microchips have a unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle doesn't 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 lot of money since they don't have to replace their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to open the doors of your car without the right key. In the past, thieves would simply force the ignition switch of your car into the "on" position using the flat screwdriver, or make use of hot-wires to bypass the system entirely. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you insert the transponder keys into the ignition the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will detect that the key is legitimate and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer certain vehicles can only recognize certain types of transponder chip. This is why it is important to ensure that your locksmith in the automotive industry is equipped to program your vehicle's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that is compatible with different models and manufacturers of cars. This is a cheaper solution than buying individual tools for every brand of vehicle. These are less common however, there are specialist automotive key programmers that are able to only work on a specific brand of vehicle. The best automotive locksmiths will have the proper tools to deal with any kind of vehicle, so make sure you choose a reputable firm with these kinds of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to unlock doors and start the engine with the push of a button. You can also use the buttons to activate features such as trunk locks, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled by the button presses, such as a "smart" key fob that allows you to get your car to parking spots that are tight as you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith if the one you have has stopped working. A professional is better equipped to connect the computer of your car via the OBD port under the steering wheel.
The majority of key fobs come with security features that make it difficult for attackers to duplicate and copy the signals they transmit. These include pseudo-random sequence generators that generate a new unlock code each time you press the button on the key fob. This prevents attackers capturing and replaying the unlock signal in order to gain access to your vehicle.
In many instances you can buy a replacement key fob from the dealer or from another retailer and have it programmed by your locksmith in your car to work with your specific vehicle. This is because the majority of the major US and Asian automobile manufacturers use key fob programming protocols with third-party companies that make the tools that locksmiths for auto employ to program their customers' keys.
Some aftermarket key fobs may be marketed as compatible with any vehicle. However, professional locksmiths recommend against using them because they're more likely to perform poorly or not even work at all. They suggest buying fobs designed specifically for your vehicle to ensure they will work properly and are less susceptible to issues such as interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made huge advances in the last couple of decades. Today's vehicles are computer-driven. A transponder chip is an essential part of this technology. It must be programmed by a locksmith, mechanic or dealer to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a movie) and the car won't start without the proper key.
These key fobs are a bit more complex than your traditional mechanical key and that's why you'll usually find them in the hands of an expert professional auto locksmith. The cost of the car key fob can vary according to the model and type of key, but it is typically between $85 and $400. This includes the labor cost to program the keyfob as well as any replacement parts.
The car key fobs are more complicated because they utilize a software system that works with the onboard computer of the car. The software prevents unauthorised access by only allowing keys programmed for a specific vehicle to function. 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 common method to do this is by using the car key programming tool that is compatible with the brand of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle, and then enter the programming mode. The key programming tool could be a programming keys handheld device that is inexpensive device or a fancy one that can perform various things that go beyond key programming (like reading and cloning eeprom files in the ECU).
Although some people might attempt to program their own keys using these tools, this is an activity best left to a professional auto locksmith. Unless you're familiar with all the ins and outs of the various software systems, it's possible to accidentally alter settings that could damage 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 you can use to unlock doors and turn on the ignition. However, modern vehicles have transponder chips that need to be recognized by the computer system of the car to begin. This is an extra layer of security that stops car thieves from starting a stolen car and driving away with it. A locksmith who is certified has the tools and software to create a 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 car. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. This will put your car into the mode of programming that will allow the locksmith to add a new key into the system.
The key scanner that is programmed communicates with the computer in the vehicle to transmit a code. The computer will recognize the code and add it to the list of keys approved by. In some instances scanners can delete lost or stolen keys.
You can also program new keys with EEPROM. It is more complicated and requires a thorough understanding of electronic systems. It is best to delegate it to a professional who has knowledge of these systems.
Locksmiths can program a key quickly using onboard programming. It can take as little as an hour if everything is done correctly. If the key is not in the correct condition or the procedure isn't being followed precisely, the procedure could take as long as a half hour.
There are many different key programmer scanners that can be used with various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both popular amongst locksmiths because they can be used with a variety of automobile models. However, neither will be able to program every vehicle on the market. Additionally, these devices are expensive. It is best to buy a programmer which will receive regular updates from the manufacturer as new technologies are developed. In the event that your machine is not updated, it will become obsolete quickly.
