Automotive Locksmith Key Programming
The majority of modern cars require some type of key programming. Depending on the model and manufacturer the procedure could be as simple as using a spare key to program the onboard computer or as complicated as OBD2 programming or EEPROM.
Most US and Asian car makers share their programming protocols with auto tool makers in order to create hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio waves. The microchips are equipped with a unique serial number which authenticates your key when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an enormous success in preventing theft of cars. It also saves many car owners a significant amount of money as they don't need to replace their vehicles.
The principle behind the transponder system is to make it impossible for thieves to start your car without a key. In the past car thieves would use a flat screwdriver to force the ignition switch in your car into "on" mode, or wire it hot to get around the system. These types of thefts have drastically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send a signal that is detected by a hidden antenna around the barrel of the ignition. This antenna is programmed so that it can read the specific frequency of the chip within the key. The car's onboard computer will then recognise that the key is valid and allow the fuel to flow, then power up the starter, or even begin it.
Certain vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different models and manufacturers of cars. This is a far more cost-effective approach than purchasing specific tools for each model of vehicle. They are not as common however, there are specialist automotive key programmers that can only work on a particular brand of vehicle. The top automotive locksmiths have the appropriate tools to work on any type of vehicle, so ensure you choose a reputable business with these kinds of tools.
Key FOBs
Key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and start the engine with the push of a button ignition. You can also use the buttons to trigger features such as trunk locks, door locks or fuel flap controls. Certain fobs can be controlled by pressing buttons. For example an "smart key" that lets you call your car to tight parking spaces, like a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the help of a user manual but you'll usually need an automotive locksmith to get a brand new one programmed if the one you have isn't functioning. This is because a professional has the specialized equipment and access to the programming tools needed to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators, which generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase an alternative keyfob from a dealership or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that produce the tools used by locksmiths who program their customers' keys.
Although some key fobs from the aftermarket are advertised as compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them as they are likely to function poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they function properly and are less prone to issues such as interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has progressed a lot and modern vehicles require computer technology to function. A transponder chip is an essential component of this technology. It has to be programmed by a locksmith mechanic or dealer to function. Key fobs come with security features that prevent hot-wiring like in a movie. The car will not start without the correct keys.
These key fobs are a bit more complicated than a traditional mechanical key and that's why they are usually in the hands of a reputable, professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the type of key however they usually cost between $85 and $400. This includes the labor required to program the key fob as well as the cost of any needed replacement parts.
These car key fobs are more intricate because they utilize an operating system that communicates with the computer onboard of the car. The software prevents unauthorized access by only allowing the key to function only if it's programmed to the car in question. If you replace your keys, you'll need to program the new key fob to the car in order for it to function.
The most common method to do this is by using a car key programming tool that is compatible with the model of the vehicle. This tool G28 Car Keys 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 that go beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people might attempt to program their keys on their own using these tools. However it's best to leave this task to an expert auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's very easy to accidentally change settings that could damage the vehicle. The most important thing to keep in mind is that an experienced professional can help you avoid these issues.
On-Board Programming
If your car is old enough it could still be equipped with a metal key that can be used to open doors and turn on the ignition. Modern vehicles have transponders that must be acknowledged and accepted by the computer system to start. This adds another security measure to prevent thieves from starting and then driving off with a stolen vehicle. A locksmith who is certified will have the tools and software needed to program a key that can work in your car's system.
Your locksmith will need to obtain a key blank that is that is compatible with your car's model and make. Once the key is received, your locksmith will link the scanner that is used for programming to the diagnostic port of your car. This will place the car into a special programming mode which will allow the locksmith to add a new key into the system.
To do this, the key programming scanner will communicate with the car's computer to send a particular code. The computer will be able to recognize the code and add it to the list of approved key. In some cases 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's best to leave it to a professional who has experience with these systems.
Locksmiths can program a key quickly using onboard programming. It takes as little as an hour if everything is executed correctly. If the key isn't in the proper state or the procedure isn't strictly followed, it could take up to a half hour.
There are a variety of key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their broad range of vehicle models. There is no system that can program every vehicle. They are also expensive. It is recommended to purchase a programmer which will receive regular updates from the manufacturer whenever new technologies are introduced. Your programming machine will quickly become obsolete if you do not do this.
