Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the process can be as simple as onboard programming using an extra working key or as complicated as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool makers so that they can develop software and hardware for automotive locksmiths to use.
Transponder Chips
The majority of newer cars have what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. They have an unique serial number that authenticates your key when you connect it 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 a huge success in preventing theft of cars. It has also saved many car owners a lot of money because they don't need to replace their cars.
The principle of the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past, thieves used a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode, or wire it hot to evade the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert the transponder keys in the ignition the signal is picked up by an antenna hidden around the barrel. This antenna is programmed so that it can detect the specific frequency of the chip within the key. The onboard computer of the car will recognize the key as valid and allow fuel flow and power the starter to start the engine.
Based on the manufacturer, certain vehicles can only recognize the specific type of transponder chip. This is why it's essential to ensure that your locksmith in the automotive industry has the right equipment to program your car's key and fobs correctly.
A reputable locksmith for cars should have a multi-vehicle key programming device that works with different models and car brands. This is a far cheaper alternative than buying specific tools for each model of vehicle. They are not as common however, there are specialist automotive key programmers that are able to only be used on a specific model of vehicle. The most reliable automotive locksmiths will have the proper tools to deal with any kind of vehicle, so ensure you choose a reputable business with these kinds of tools.
Key FOBs
Key FOBs are programmeable transponder chips that allow your vehicle to unlock doors and begin the engine with the push of a button. You can also press buttons to activate features like door locks, trunk releases or control of the fuel flap. Some fobs have additional functions that can be controlled by the button presses like the "smart" key fob that allows you to summon your car into tight parking spots as you would with a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the help of a user manual but you'll usually require an auto locksmith to get a new one programmed if the one you have isn't functioning. This is because a professional locksmith has the equipment that is specialized and access to the tools for programming needed to connect your car's computer through the OBD (OBD) port that is located under the steering wheel.
Today, most key fobs come with security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. Certain key fobs come with pseudo-random code generators that generate a unique unlock code each time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most cases you can purchase an additional key fob at the dealer or from another retailer and have it programmed by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that create the tools used by auto locksmiths to program their customer's keys.
Certain aftermarket key fobs can be advertised as being compatible with vehicles of all kinds. However, automotive locksmiths strongly discourage using them as they're more likely to perform poorly or even not at all. They recommend buying fobs made specifically for your vehicle so that they will work properly and are less prone to issues such as interference or incompatibility. This will save money in the long run by avoiding costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
The automotive industry has made huge advancements in the past few decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chipset that requires to be programmed to the vehicle by an auto locksmith or dealer/mechanic order to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car won't start without the proper key.
Key fobs are slightly more complicated 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 model and type of key, but is generally between $85 to $400. This includes the cost of labor 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 utilize a specific software system to communicate with the car's onboard computer. The software blocks access to unauthorized users by only allowing the key to operate only if it's been programmed to that specific car. If you replace your keys, you'll have to program the new key fob in the car in order for it to work.
This is accomplished by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. Key programming tools can be a simple handheld device or a fancy one that can perform various things that go beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people try to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith. If you're not aware of all the details of the various software systems, it's possible to accidentally change settings that could damage the vehicle.

To accomplish this, the key programming scanner will communicate with the car's computer system to transmit a specific code. The computer will be able to recognize the code and add it to the list of keys approved by. In some cases, the scanner will also be able to erase lost or stolen keys from the system.
You can also program new keys by using the EEPROM. It is more complex and requires a deep understanding of how electronic systems function. This is why it should be left to a professional who has years of experience working on these types of systems.
Locksmiths can program keys quickly using onboard programming. It can take as little as a minute when everything is completed correctly. If the key isn't in proper state or the procedure is not adhered to, it could take up to a half hour.
There are many different key programmer scanners that support various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their wide selection of models for vehicles.

It is best to buy an instrument that receives regular updates from the manufacturer as new technologies are introduced. Your machine for programming will quickly become obsolete if you do not do this.
