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 a spare key to program the onboard computer or as complex as OBD2 programming or EEPROM.
The majority of US and Asian automakers have a programming protocol that they share with auto tool makers, which means they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are found in a lot of modern cars to guard against theft of vehicles. These are small computer microchips that emit radio signals at a low level. They have a unique serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proven to be extremely successful in preventing theft of cars. This technology has also saved car owners a great amount of money by not having to buy new vehicles.
The principle behind the transponder system is to make it impossible for thieves to start your car without the proper key. In the past, thieves used a flat screwdriver to force the ignition switch of your car into the "on" mode or even wire it hot to bypass the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is received by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip within the key. The onboard computer in the car will recognize the key as valid and will allow fuel flow, power the starter or start the engine.
Some vehicles only recognize specific type of transponder chip, depending on the manufacturer. This is why it's crucial to make sure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs properly.
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 more cost-effective alternative to purchasing individual tools for every brand of vehicle. There are also specific automotive key programmer devices that are only suitable for specific models of vehicles, but these are less popular. The best automotive locksmiths have the tools to work on any vehicle. Make sure you choose a reliable company that is equipped with this type of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and begin the engine with a push 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. Certain fobs can be controlled with the press of buttons. For example, a "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement key fobs can be programmed with the aid of a user's guide however, you'll typically require an automotive locksmith to have a new one programmed in case yours stops functioning. A professional is better equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
The majority of key fobs today come with security features that make it difficult for criminals to duplicate or duplicate the signals they transmit. Certain key fobs come with pseudo-random code generators, which generate a unique unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal in order to gain access to your vehicle.
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 because the majority of major US and Asian auto manufacturers use the same key-fob programming protocol with the third-party firms who produce the tools used by locksmiths for programming their customer's keys.
While some aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them since they're likely to work poorly or not at all. Instead, they suggest purchasing fobs designed specifically for your vehicle, so that you can be certain they'll function correctly and are less prone to issues such as interfering or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tool
The automotive industry has made great strides in the last few decades. Today's vehicles are computer-driven. One key element of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs are fitted with security features that prevent hot-wiring, as in a movie. The car won't start if the keys are not correct.
These key fobs are a little more complicated than a traditional mechanical key and are the reason you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob may vary based on the vehicle model and the key type however they usually cost between $85 to $400. This includes the cost of labor to program the key fob, as well as the read more costs for any required replacement parts.
To make the process more complicated the car key fobs use a special software system to work with the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys programmed for a specific vehicle to work. This means that if you need your keys replaced, you'll need have the new key fob programed to the car in order for it to work.
The most popular method to do this is by using a car key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. The key programming device could be a handheld device that is cheap or fancy and can do more than just program keys (like reading the eeprom file in the ECU).
While some may try 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 ins and outs of the various software systems, it's easy to make a mistake and alter settings that could cause damage to the vehicle. The most important thing to keep in mind is that a professional with experience can assist you in avoiding these issues.
On-Board Programming
If your car is older than, it may still come with a key made of metal that you can use to open doors and turn off the ignition.

This is an additional layer of security that prevents car thieves from starting a car stolen and then driving off with the car. A locksmith who is certified will have the necessary tools and software to create a key that is compatible with your car's security system.

Once the key is received, your locksmith will link the scanner for programming to the diagnostic port of your car. This will place the 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 specific code. The computer will recognize this code and add it into the list of approved key. In certain instances, the scanner will also be able to delete lost or stolen keys from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of how electronic systems function. This is why it's best left to a professional that has a lot of expertise working on these types of systems.
Locksmiths can program keys quickly by using onboard programming. It can take as little as a minute when everything is executed correctly. However, if the key isn't placed in the proper condition or the procedure is not followed exactly, it can take up to a half hour.
There are numerous key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they support a broad range of automobile models. The system cannot program every vehicle. These devices are also expensive. It is best to buy one that will receive regular updates from the manufacturer as new technologies are developed. Your computer's programming software will soon become obsolete if you don't do this.
