Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers so that they can develop software and hardware for automotive locksmiths to use.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of low-level. The microchips have a unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a good deal of money as they do not have to replace their vehicles.
The fundamental idea behind the transponder system is to make it difficult for thieves to start your car without the proper key. In the past, thieves would use the flat screwdriver to push the ignition switch of your vehicle into the "on" mode or even hot-wire it to evade 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 transmits the signal which is received by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The car's onboard computer will then detect that the key is genuine and allow the fuel to flow, then power up the starter, or even start it.
Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith will utilize a multi-vehicle programmable 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. These are less common but there are automotive key programmers that can only be used on a specific model of vehicle. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. They also have buttons that you can press to trigger features such as trunk release, door locks or control of the fuel flap. Some fobs can be controlled by pressing buttons. For instance the "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from an instruction manual, however you'll need to contact an automotive locksmith if the one you have isn't functioning. This is because a professional has the specialized equipment and access to the programming tools required to connect your car's computer through the on-board diagnostics (OBD) port beneath the steering wheel.
Today, most key fobs come with security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. Certain key fobs feature 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 most instances you can buy a replacement key fob from the dealer or from another retailer and have it programmable by your automotive locksmith to fit your specific vehicle. This is because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with third-party companies that make the tools used by auto locksmiths to program their customers' keys.
Some aftermarket key fobs may be marketed as being compatible with vehicles of all kinds. However, locksmiths for automotive advise against using them since they're likely to function poorly or not even work at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements of your fobs.
Tools for programming vehicles used by manufacturers
Automotive technologies have come a long way, and today's vehicles require computer technology to function. One of the most important components of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs come with security features to prevent hot-wiring like in a film. The car won't start without the correct keys.
Key fobs are a bit more complex than your traditional mechanical keys and are the reason you'll usually find them in the hands of a reputable, professional auto locksmith. The cost of the car key fob can vary dependent on the model and type of key, but it is generally between $85 and $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
To complicate the process the car key fobs utilize a specific software system to connect to the car's onboard computer. The software prevents unauthorized access by allowing the key to operate only if it's programmed to that specific car. If you replace your keys, you will have to program the new key fob into the car in order for it to work.
This is accomplished using a programming tool for keys for cars that are 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 can be an handheld device that is affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom file in the ECU).
While some people may attempt to program their own keys with these tools, it's something best left to a professional auto locksmith. Unless you're familiar with all the details of the various software systems, it's possible to accidentally alter settings that could potentially damage the vehicle. The most important thing to remember is that an experienced professional can help you avoid these issues.
On-Board Programming
If your car is of a certain age to be considered old-fashioned, here you'll have a traditional key made of metal that you can use to open the doors and turn over the ignition. Modern vehicles have transponders that need to be recognized and accepted by the computer system before it can start. This is an extra layer of protection that can stop car thieves from stealing a car and driving away with the car. A certified locksmith will have the necessary tools and software to create a new key that is compatible with your car's security system.
First, your locksmith will require an uncut key that is compatible with the make and model of your car. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put the car in a special programming mode, which will allow locksmiths to add the key to the system.
To do this, the key programmer scanner will communicate with the car's computer system to transmit a particular code. The computer will be able to recognize the code and add it into the list of keys that are approved. 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 complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the fastest method for locksmiths to program an entirely new key. It can take as little as an hour if everything is executed correctly. If the key isn't in the right condition or the procedure isn't being followed precisely, the procedure could take up to half an hour.
There are numerous key programmer scanners on the market that support different vehicle models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide selection of vehicle models. However, neither can be programmed for every vehicle on the market. These machines are also quite expensive. It is a good idea to purchase a programer that is updated regularly as the manufacturer releases new technologies. Otherwise, your programming machine will become obsolete quickly.
