automotive locksmith Key Programming (
hns.tium.co.kr)
Modern vehicles 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 automakers have a programming protocol that they share with auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in a lot of modern cars to stop theft of cars. These are tiny computer microchips which emit radio waves of low-level. The microchips are equipped with 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 proven to be an incredible success in preventing auto theft. It also saves many car owners a lot of money because they don't need to replace their cars.
The principle of the transponder system is to make it difficult for thieves to get into 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 even wire it hot to evade the system. These kinds of thefts have been drastically reduced with the introduction of the transponder chip.
When you place the transponder key into the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will recognise that the key is legitimate and allow fuel to flow, turn the starter or begin it.
Depending on the manufacturer certain vehicles can only accept the specific type of transponder chip. This is why it's crucial to make sure that your automotive locksmith is equipped to program your vehicle's keys and fobs correctly.
A good automotive locksmith will possess a multi-vehicle programing device that can be used on many different models and brands of cars. This is a cheaper option than purchasing specific tools for each type of vehicle. There are also specialised key programming tools for automobiles that can only be used on specific brands of vehicles however they are not as popular. The most reliable automotive locksmiths will have the appropriate equipment to tackle any type of vehicle, so make sure you choose a reputable firm with these kinds of tools.
Key FOBs
The name implies that key FOBs are home to the programmable transponder chips that enable your vehicle to identify and unlock the doors or start the engine using push-button ignition. They also have buttons you can push to activate features like trunk release, door locks or fuel flap control. Certain fobs can be controlled by pressing buttons. For instance the "smart key" which allows you to summon your car into tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the help of a user manual but you'll usually need an automotive locksmith to get a new one programmed if the one you have isn't functioning. This is because a professional has the equipment that is specialized and access to the tools for programming needed to connect your car's computer to the OBD (OBD) port beneath the steering wheel.
The majority of key fobs are equipped with security features that make it difficult for attackers to replicate and clone the signals that they transmit. These include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on the key fob. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most cases you can purchase a replacement key fob from the dealer or from another retailer and have it programmable by your automotive locksmith to fit your particular vehicle. This is because the majority of the major US and Asian automobile manufacturers share their key fob programming protocols with third-party companies that create the tools auto locksmiths utilize to program keys for their customers.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, automotive locksmiths recommend against using them because they are likely to work poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they work correctly and are less susceptible to issues like interference or incompatibility. This will save money over time, as you avoid costly repairs or replacements of your fobs.
Tool for programming the vehicle manufacturers
The automotive industry has made great advances in the last couple of decades. Today's vehicles are computer-driven. A transponder chip is an essential part of this technology. It needs to be programmed by a locksmith, mechanic or dealer to function. Key fobs come with built-in security features that prevent hot-wiring (like in a film) and the car won't start without the proper key.
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 and $400. This includes the labor to program the key fob and the costs for any necessary replacement parts.
To complicate the process, these 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 that have been programmed for a specific car to function. This means that if your keys replaced, you'll need to have the new key fob programmed to the

This is done by using a programming tool for car keys that is compatible with the vehicle's brand. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming device can be a handheld device that's inexpensive or one that is fancy and can do more than just program keys (like reading the eeprom file inside the ECU).
While some may try to program their own keys using these tools, this is something best left to a professional auto locksmith. If you're not aware of all the details of the various software systems, it's easy to accidentally change settings that could cause damage to the vehicle. The most important thing to remember is that a skilled professional can assist you in avoiding these issues.
On-Board programming
If your car is of a certain age, you'll still have a key from the past to use to unlock the doors and turn off the ignition. Modern cars come with transponders that need to be recognized and accepted by the computer system to start. This is an additional layer of security that prevents car thieves from stealing a car and then driving off with the car. A locksmith who is certified will have the tools and software needed to program a key that can function in your
car keys cut and programmed's system.
The locksmith needs to purchase a blank key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will place the car into the mode of programming that allows the locksmith to add a new key into the system.
The key scanner that is programmed communicates with the computer in the vehicle to send a code. The computer will recognize the code and add it to the list of keys approved by. In some instances the scanner will be able to remove lost or stolen keys from the system.
Programming EEPROM is another method that can be used to program new car keys.
