Automotive Locksmith Key Programming
Most modern-day cars require some type of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming with a spare key that works or as complex as OBD2 or EEPROM programming.
Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can create 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 low-level radio waves. 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 been an incredible success in preventing auto theft. It has also saved many car owners a lot of money as they don't need to replace their vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to get into your car without the proper key. In the past, car thieves used the flat screwdriver to push the ignition switch of your vehicle to go into "on" mode or even hot-wire it to bypass the system. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder key into the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to read the specific frequency of the chip within the key. The onboard computer in the car will then recognise the key as being valid and will allow fuel flow and power the starter to begin the engine.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have a multi-vehicle key programming tool that can work on many different models and car brands. This is a far cheaper alternative than buying separate tools for each type of vehicle. These aren't as popular, but there are specialised automotive key programming tools that can only work on a specific type of vehicle. The top automotive locksmiths have the proper tools to deal with any kind of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs
The key FOBs are programmable transponder chip devices that allow your vehicle to unlock doors and begin the engine with the push of a button ignition. They also have buttons you can press to trigger features such as door locks, trunk release or fuel flap control. Certain fobs can be controlled by pressing buttons. For instance, a "smart key" which allows you to summon your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help of an instruction manual, however you'll need to call an automotive locksmith in the event that yours has stopped working. This is because a professional has the right equipment and access to the programming tools required to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
Most key fobs today include security features that make it difficult for hackers to clone or replicate the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code each time you press the button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your car.
In certain instances you can purchase an alternative keyfob from an authorized dealer or another retailer. Your locksmith at your auto will then program it to work with your vehicle. This is due to the fact that most of the major US and Asian automobile manufacturers have key fob programming protocols with third-party firms that create the tools locksmiths utilize to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with any vehicle however, the majority of locksmiths for automotive do not recommend using them because they are likely to function poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle so that you can be sure they'll work properly and are less susceptible to issues such as interfering or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has made great advances in the last couple of decades. Today's vehicles are computer-driven. One key element of this technology is a transponder chipset that must be programmed into the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs are fitted with security features to stop hot-wiring, like in a movie. The car won't start if the keys are not correct.
These key fobs are a bit more complex than the 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 depending on the model and type of key, but it is usually between $85 and $400. This includes the labor required to program the key fob as well as the costs for any required replacement parts.
To make the process more complicated to make the process more complicated, these key fobs for cars make use of a special software to connect to the car's onboard computer. The software blocks unauthorized access by permitting the key to function only if it's programmed for the specific car. If you replace your keys, you'll have to program the new key fob in the car for it to function.
This is done by using a programing tool for car keys that is compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port in the vehicle and then enter the programming mode. The key programming device could be a handheld device that's cheap or fancy and can do more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys using these tools, it's something best left to a professional auto locksmith. If you're not familiar with the aspects of the various software systems, it's possible to accidentally alter settings that could potentially damage the vehicle. It's important to keep in mind that an experienced professional will assist you in avoiding these issues.
On-Board Programming
If your vehicle is of a certain age that you'll have a traditional metal key to use to unlock the doors and turn over the ignition. Modern vehicles have transponders that need to be acknowledged and accepted by the computer system before it can start. This is a further layer of security that prevents 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 work in your car's system.
First, your locksmith will require a blank key that is compatible with the make and model of your vehicle. Once the key is received, your locksmith will link the scanner for programming to your car's diagnostic port. This will put your car into an exclusive programming mode which will allow the locksmith to add a new key to the system.
To accomplish this, the key programmer scanner will communicate with the car's computer and send a particular code. The computer will be able to recognize the code and add it to the list of approved keys. In certain instances the scanner may also be able to delete keys that have been stolen or lost from the system.
You can also program new keys by using EEPROM. It is more complex and requires an in-depth understanding of how electronic systems work. This is why it should be left to a professional that has years of experience working with these kinds of systems.
Onboard programming is the quickest way for a locksmith to program a new key. It can take as little as an hour if everything is done correctly. If the key is not in the right condition or the procedure isn't being followed exactly, the process could be as long as half an hour.
There are many different key programmer scanners that can be used with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their wide selection of vehicle models. However, neither can program every vehicle in existence. They are also expensive. It's a good idea buy a programmer that receives regular updates when the manufacturer introduces new technologies. Your programming machine will quickly become obsolete if you don't take this step.
