Automotive Locksmith Key Programming
Modern cars need some type of key programming. Based on the model and make, the process may be as simple as using an additional key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian auto manufacturers share their programming protocol with auto tool manufacturers, so they can develop software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also helped car owners save a good deal of money since they don't have to buy new vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without the correct key. In the past, thieves would simply push your car's ignition switch into the "on" position using the flat screwdriver, or make use of hot-wires to bypass the system altogether. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which is received by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow fuel to flow, power up the starter, or even begin it.
Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have a multi-vehicle key programming tool that works with different models and manufacturers of cars. This is a cheaper alternative to purchasing separate tools for each brand of vehicle. These aren't as popular however, there are specialist automotive key programming tools that can only be used on a specific type of vehicle. The most reliable automotive locksmiths will have the appropriate tools to work on any type of vehicle, so make sure you choose a reputable business with these kinds of tools.
Key FOBs
As the name implies, key FOBs house the transponder chips that can be programmed to allow your car to recognize and unlock the doors or start the engine using a push button ignition. It is also possible to press buttons to activate features such as door locks, trunk releases or control of the fuel flap. Some fobs have additional functions that can be controlled by the press of a button for example, the "smart" key fob that allows you to get your car to parking spots that are tight, like you would with a Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the help of a user manual however, you'll typically require an automotive locksmith to have a new one programmed if yours stops working. This is because an expert locksmith has the equipment that is specialized and access to the tools for programming needed to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features to make it difficult for attackers to replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In many instances you can purchase an alternative key fob from 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 the majority of major US and Asian auto manufacturers share their key-fob programming protocols with third-party companies that create the tools used by locksmiths for programming their customer's keys.
Some aftermarket key fobs may be marketed as being compatible with all vehicles. However, professional locksmiths advise against using them since they are likely to work poorly or not work at all. They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Vehicle Manufacturers' Programming Tool
The automobile industry has made significant strides in the last few decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chipset that needs to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. These key fobs are equipped with security features to stop hot-wiring like in a film. The car will not start without the correct keys.
These key fobs are more complex than your traditional mechanical keys, which is why you'll usually find them in the hands of an expert professional auto locksmith. The cost of a key fob will vary depending on the car model and the key type however, they generally cost between $85 and $400. This includes the labor cost to program the keyfob as well as any replacement parts.
These car key fobs are more intricate because they utilize a software system that works with the computer onboard G28 Car Keys of the car. The software blocks access to unauthorised users by only allowing keys that have been programmed for a specific car to work. This means that if you get your keys replaced, you'll have to have the new key fob programmed to the car in order 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 allows a locksmith to connect to the OBD port in the vehicle and then enter the programming mode. Key programming tools can be a simple handheld device or a high-end one that is capable of performing many things beyond just key programming (like reading and cloning the Eeprom files within the ECU).
While some people may attempt to program their own keys with these tools, this is an activity best left to an experienced auto locksmith. It's easy to make mistakes with the software systems if you aren't aware of the intricacies. This could lead to damage. It's important to remember that an experienced professional will help you avoid these issues.
On-Board programming
If your vehicle is old enough that you'll have a traditional key made of metal to open the doors and turn on the ignition. However, modern vehicles have transponder chips that must be recognized by the car's computer system to begin. This adds another security measure to prevent thieves from starting and driving away with a stolen vehicle. A certified locksmith will have the right tools and software to create a new key that is compatible with your car's security system.
The locksmith will require a blank 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 an exclusive programming mode which will allow the locksmith to add a new key into the system.
To do this, the key programmer scanner will communicate with the car's computer system to transmit an exact code. The computer will recognize this code and include it into the list of keys that are authorized. In some cases, a scanner can also remove keys that have been stolen or lost.
You can also program new keys using the EEPROM. It is more complicated and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has expertise with these systems.
Locksmiths can program keys quickly using onboard programming. It takes as little as an hour if everything is completed correctly. However, if the key isn't placed in the correct state or the procedure isn't adhered to, it could take up to an hour.
There are a variety of key programmer scanners that can be used with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they support a broad range of automobile models. There is no system that can program every vehicle. They are also expensive. It is a good idea to purchase a computer that will get regular updates when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you don't do this.
