Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the model and manufacturer, the process may be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian car manufacturers have programming protocols that they share with auto tool manufacturers in order to create tools and hardware for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. This technology has also saved car owners a great amount of money by not having to replace their vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to open the doors of your car without a key. In the past, car thieves would use a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode or even hot-wire it to get around the system. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder keys into the ignition, it transmits the signal which is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Some vehicles only recognize a certain type of transponder chips according to the manufacturer. It is therefore important that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive will utilize a multi-vehicle programmable tool that can be used with different models and brands of cars. This is a less expensive option than purchasing individual tools for every brand of vehicle. There are also specific key programming devices for automotive that can only be used on specific models of vehicles, but these are less frequently used. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reliable company that is equipped with this type of equipment.
Key FOBs
As the name suggests, key FOBs are home to the programmable transponder chips that allow your vehicle to recognize and open the doors, or start the engine using push-button ignition. They also have buttons you can press to trigger features such as door locks, trunk release or control of the fuel flap. Certain fobs can be controlled using buttons. For instance the "smart key" that lets you call your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from the user guide, however you'll need to contact an automotive locksmith if yours has stopped working. A professional is better equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
The majority of key fobs come with security features that make it harder for attackers replicate and clone the signals that they transmit. Some key fobs have pseudo-random code generators which generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many instances, you can purchase a replacement key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to fit 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 locksmiths use to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them since they will likely only work poorly or not at all. Instead, they suggest purchasing fobs designed specifically for your specific vehicle so that you are certain they'll work properly and are less prone to issues such as interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has made huge strides in the last few decades. Today's cars are computer-driven. One of the key components of this technology is a transponder chip which requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to work. automotive key programming have built-in security features that stop hot-wiring (like in a movie) and the car will not start if you don't have the correct key.
These key fobs are a little more complex than your traditional mechanical key and that's why you'll usually find them in the hands of a skilled, professional auto locksmith. The cost of a key fob can differ based on the vehicle model and the key type, but they typically run between $85 and $400. This includes the cost of labor to program the key fob and the cost of any needed replacement parts.
Car key fobs are more complex because they use software that interacts with the onboard computer of the car. The software blocks access to unauthorized users by permitting the key to function if it has been programmed to that specific car. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car for it to work.
The most popular method to do this is by using a 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. Key programming tools can be a handheld device that is inexpensive device or a high-end one that is capable of performing a wide range of things beyond just key programming (like reading and cloning EEEPROM files in the ECU).
Some people may try to program their keys themselves using these tools. However, this is best left to an experienced auto locksmith. If you're not familiar with 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 remember that an experienced professional will help you avoid these issues.
On-Board programming
If your vehicle is of a certain age, you'll still have a key from the past that you can use to open the doors and turn on the ignition. However, modern cars come with transponder chips that must be recognized by the computer system of the car to allow it to start. This is an additional layer of security to keep car thieves from starting and then driving off with a stolen car. A locksmith certified will have the tools and software needed to program a key that can be compatible with your car's security system.
The locksmith will need to get an uncut key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he will connect the scanner for programming to the diagnostic port of your vehicle. This will place the 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 of the vehicle to transmit an electronic code. The computer will be able to recognize this code and add it to the list of approved key. In some instances scanners can remove keys that have been stolen or lost.
Programming EEPROM is another method that can be used to program new car keys. It is more complex 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 keys quickly using onboard programming. When everything is done correctly, it can take just one minute. However, if the key isn't in the right situation or the procedure is not strictly followed, it could take as long as a half hour.
There are a variety of key programmer scanners which can work with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicles. There is no system that can program every vehicle. They are also expensive. It's a good idea to buy a programmer that receives regular updates when the manufacturer introduces new technologies. Your computer's programming software will soon become obsolete if you don't take this step.
