Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can develop tools or hardware for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit radio waves at a low level. The microchips are equipped with a unique serial number which authenticates your key when you plug it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proved to be an immense success in stopping auto theft. It also saves many car owners a lot of money since they don't have to replace their cars.
The fundamental idea behind the transponder system is to make it impossible for thieves to get into your vehicle without a valid key. In the past, thieves would force your ignition switch to the "on" position using a flat screwdriver or even use hot wires to disable the system altogether. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The car's computer onboard will detect that the key is legitimate and allow fuel to flow, turn the starter or start it.
Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it's essential to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs properly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming tool that works with different models and car brands. This is a cheaper option than buying specific tools for each model of vehicle. They are not as common, but there are specialised automotive key programmers that are able to only work on a particular model of vehicle. The most reliable automotive locksmiths will have the appropriate tools to deal with any kind of vehicle, so be sure you choose a reputable business that has these types of tools.
Key FOBs
Key FOBs are programmable transponder chips that allow your vehicle to open doors and start the engine with the push of a button. You can also press buttons to trigger features such as trunk locks, door locks or fuel flap controls. Certain fobs can be controlled with the press of buttons. For example, a "smart key" that allows you summon your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the assistance of a user's manual, you'll often need an automotive locksmith to get a brand new one programmed if yours stops functioning. This is because an expert locksmith has the equipment that is specialized and access to the tools for programming needed to connect your car's computer via the OBD (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to duplicate and copy the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances you can purchase an alternative keyfob from an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your car. This is because the majority of major US and Asian automakers share their key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customer's 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're likely to work poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your vehicle so that you can be sure they'll function correctly and are less susceptible to issues like interfering or not working. This will save you money over the long term by avoiding expensive repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tools
The automobile industry has made significant advances in the last couple of decades. Nowadays, cars are computer-driven. A transponder chip is an essential part of this technology. It needs to be programmed by a locksmith, mechanic or dealer to function. Key fobs with embedded security features that stop hot-wiring (like in a movie) and the car will not start if you don't have the proper key.
These key fobs can be a little more complex than a standard mechanical key. This is why they are usually handled by experienced professional auto locksmiths. The cost of a car key fob varies according to the type and model of key, but is generally between $85 and $400. This includes labor costs to program the keyfob and any replacement parts.
The car key fobs are more complicated because they utilize software that interacts with the onboard computer of the car. The software blocks access to unauthorized users by only allowing the key to function if it has been programmed to that specific car. If you decide to replace your keys, you'll need to program the new key fob into the car to allow it to function.
The most common way to accomplish this is using a car key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port of the vehicle and then enter the programming mode. The key programming device could be a handheld device that is affordable or fancy and can do more than just program keys (like reading the eeprom file inside the ECU).
Some people might attempt to program their keys by themselves using these tools. However this should be left to an experienced auto locksmith. It's easy to make mistakes using the software systems if you don't understand the intricacies. This could result in damage.

On-Board programming

Your locksmith will first need to obtain an uncut key that is that is compatible with your car's make and model. Once the key is received, your locksmith will link the scanner for programming to the diagnostic port of your car. This will put the vehicle into an exclusive programming mode which will allow the locksmith to add a new key to the system.
The key programmer scanner communicates with the computer in the car to send a 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 erase keys that have been stolen or lost from the system.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a thorough understanding of electronic systems. This is why it should be left to a professional who has years of expertise working on these types of systems.
Locksmiths can program keys quickly with onboard programming. It takes as little as one minute if everything is executed correctly. If the key isn't in the proper situation or the procedure isn't followed exactly, it can take up to an hour.
There are numerous key programmer scanners that can be used with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their wide range of models for vehicles. However, neither can be programmed for every vehicle in existence. These devices are also expensive. It's a good idea to purchase a computer that receives regular updates as the manufacturer releases new technologies. In the event that your machine is not updated, it will soon become obsolete.
