Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as programming onboard using a spare working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers have programming protocols that they share with auto tool manufacturers to allow them to develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have transponder chips to stop car theft. These are microchips in the form of computers which emit radio signals of 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, the engine will be shut down. This technology has proven to be an incredible success in preventing auto theft. This technology has also helped car owners save a huge deal of money as they do not have to replace 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 a flat screwdriver to force the ignition switch of your car to go into "on" mode or even hot-wire it to get around the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will send a signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's onboard computer will recognize that the key is valid and allow the fuel to flow, then power up the starter, or even start it.
Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip. This is why it is important to ensure that your locksmith for automotive is equipped to program your car's key and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different car manufacturers and models. This is a cheaper solution than buying separate tools for each brand of vehicle. They are not as common however, there are specialist automotive key programming tools that can only be used on a specific model of vehicle. The top automotive locksmiths have the tools to work on any vehicle. Make sure you select a reliable company that is equipped with this type of equipment.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. It is also possible to press buttons to activate features like trunk releases, door locks or fuel flap controls. Certain fobs can be controlled using buttons. For example, a "smart key" which allows you to summon your car to parking spaces, such as a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the assistance of a user's 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 your computer to the vehicle via the OBD port located under the steering wheel.
Today, most key fobs come with security features that make it difficult for hackers to duplicate or copy the signals they transmit. They include pseudo-random sequence generators that generate a new unlock code each time you press the key fob's button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your vehicle.
In most cases you can purchase an additional key fob at the dealer or from another retailer and have it programmed by your locksmith in your car to be compatible with your specific vehicle. This is because most of the major US and Asian car makers share their key fob programming protocols with third-party companies that create the tools auto locksmiths use to program keys for their customers.
Some aftermarket key fobs may be advertised as being compatible with all vehicles. However, automotive locksmiths strongly discourage using them as they're more likely to perform poorly or not work at all. Instead, they suggest purchasing fobs specifically designed for your specific vehicle so that you can be certain they'll function correctly and are less prone to issues like interfering or not working. This will save you money over time by avoiding costly repairs or replacements of your fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technology has advanced considerably, and today's vehicles require computer technology to function. Transponder chips are an essential component of this technology. It needs to be programmed by a locksmith mechanic or dealer to work. These key fobs have built-in security features that will prevent hot-wiring (like in a film) and the car will not start if you don't have the correct key.
Key fobs are a little more complicated than a traditional mechanical keys, which is why you'll typically find them in the hands of an expert, professional auto locksmith. The cost of a key fob can differ based on the vehicle model and the key type however, they generally cost between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
These car key fobs are more complicated because they utilize a software system that works with the computer onboard of the car. The software prevents unauthorized access by only allowing the key to operate if it has been programmed for the specific car. This means that if your keys replaced, you'll need have the new key fob programed to the car 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 allows a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. Key programming devices can be an handheld device that is affordable or sophisticated and capable of doing more than just program keys (like reading the eeprom file in the ECU).
While some people may attempt to program their own keys using these tools, it's a job best left to an experienced auto locksmith. If you're not aware of all the details of the various software systems, it's easy to accidentally alter settings that could damage the vehicle. It's important to keep in mind that a professional with experience will help you avoid these problems.
On-Board programming
If your car is old enough that you'll have a traditional metal key to open the doors and turn off the ignition. Modern vehicles have transponders that need to be recognized and accepted by the computer system in order to start. This is an extra layer of protection that can stop car thieves from starting a stolen car and driving off with it. A locksmith who is certified has the tools and software to create a new key that works with the security system in your car.
Your locksmith will need to acquire an uncut key that is compatible with your vehicle's make and model. Once your locksmith has the key, he will connect the programming scanner 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 into the system.
The key scanner that is programmed communicates with the computer of the vehicle to transmit an electronic code. The computer will recognize this code and include it into the list of approved key. In some cases the scanner may also be able to remove 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 deep understanding of electronic systems. This is why it's best left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the quickest method for locksmiths to program an entirely new key. It takes as little as an hour if everything is completed correctly. However, if the key isn't in the proper situation or the procedure isn't strictly followed, it could take up to an hour.
There are many different key programmer scanners that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide range of vehicle models. However, neither can program every vehicle in existence. In addition, these machines are quite expensive. It's a good idea to purchase a computer that is updated regularly as the manufacturer develops new technologies. Otherwise, your programming machine will become obsolete quickly.
