Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Based on the car's make and model, the process could be as simple as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian car makers use the same programming protocols as auto tool makers to allow them to develop hardware and software for locksmiths working in automotive vehicles.
Transponder Chips
Transponder chips are in many newer cars to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be a huge success in preventing theft of cars. This technology has also helped car owners save a good amount of money as they do not have to replace their vehicles.
The transponder system's basic idea is to make it difficult for thieves to get into your car without the right key. In the past, car thieves would force your car's ignition switch into the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system completely. Transponder chips have dramatically decreased the likelihood of theft.
When you insert the transponder keys into the ignition, the signal is received by an antenna that is concealed around the barrel. This antenna is programmed to detect the specific frequency of the chip within the key. The computer onboard of the car will then recognize the key as being valid and will allow fuel flow and power the starter to begin the engine.
Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it's essential to ensure that your automotive locksmith has the right equipment to program your car's keys and fobs properly.
A reliable locksmith for cars will have a multi-vehicle programming device which can be used on many different car models and manufacturers. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. There are also specialised key programming devices for automotive that are only suitable for one particular brand of vehicle, but these are less frequently used. The most reliable automotive locksmiths will have the right tools to deal with any kind of vehicle, so be sure you find a reputable company that has these types of tools.
Key FOBs
The name implies that key FOBs house the programmable transponder chips that enable your car to recognize and unlock the doors, or start the engine using push-button ignition. You can also press buttons to trigger features such as trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled by pressing buttons. For instance the "smart key" that allows you summon your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program replacement key fobs yourself with the help of the user guide, however you will need to call an automotive locksmith if the one you have has stopped working. This is because an expert locksmith has the equipment that is specialized and access to the programming tools required to connect your car's computer to the on-board diagnostics (OBD) port beneath the steering wheel.
Today, most key fobs have security features that make it difficult for hackers to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a unique unlock code each time you press the button. This is to prevent attackers from capturing and replaying the unlock signal in order to gain access to your vehicle.
In certain instances you can purchase the replacement keyfob at a dealership 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 create the tools used by auto locksmiths to program 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 even not even work at all. They suggest buying fobs designed specifically for your vehicle to ensure they function properly and are less susceptible to issues such as interference or incompatibility. This will save money over time by avoiding costly repairs or replacements for your fobs.
Tool for Programming Vehicle Manufacturers'
The automotive industry has come a long way and modern vehicles require computers to function. 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 stop hot-wiring (like in a movie) and the car won't start if it doesn't have the correct key.
Key fobs can be a little more complex than a conventional mechanical key. This is why they are in the hands of seasoned professional auto locksmiths. The cost of a key fob can differ based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the key fob and the costs for any required replacement parts.
To complicate the process the car key fobs make use of a special software to connect to the car's onboard computer. The software prevents unauthorized access by allowing the key to function if it has been programmed for the specific car. This means that if you need your keys replaced, you'll have to have the new key fob programmed to the car for it to function.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. The key programming device could be a handheld device that is cheap or extravagant 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. Unless you're familiar with all the details of the various software systems, it's very easy to accidentally alter settings that could cause damage to the vehicle. It's important to keep in mind that a knowledgeable professional can assist you in avoiding these issues.
On-Board Programming
If your vehicle is of a certain age to be considered old-fashioned, you'll have a key from the past that you can use to open the doors and turn on the ignition. Modern cars have a transponder chip that must be recognized by the car's computer system to begin. This is an additional layer of security that stops car thieves from stealing a car and driving off with it. A licensed locksmith will have the right tools and software to program a new key that is compatible with the security system of your vehicle.
First, your locksmith will require an uncut key that is compatible with the model and make of your vehicle. Once the key is in hand the locksmith will connect the scanner for programming to the diagnostic port of your car. This will put the vehicle into the mode of programming that allows the locksmith to add a new key to the system.
The key scanner that is programmed communicates with the computer of the car to send an electronic code. The computer will be able to recognize this code and add it into the list of keys that are authorized. In some instances the scanner will be able to remove lost or stolen keys from the system.
You can also program new keys by using EEPROM. It is more complex and requires a deep understanding of how electronic systems operate. It's best to leave it to a professional with experience with these systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. It can take less than a minute when everything is completed correctly. If reprogram car key is not in good working order or the procedure isn't being followed precisely, the procedure could take up to half an hour.
There are many key programmer scanners that can be used with different vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their wide range of vehicle models. However, no system can program every vehicle in existence. They are also expensive. It's a good idea to purchase a computer that will get regular updates when the manufacturer introduces new technologies. Otherwise, your programming machine will become obsolete quickly.
