Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using a spare key that works or as complicated as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers so that they can develop hardware and software for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be a huge success in preventing car theft. This technology has also saved car owners a great deal of money by not having to buy new vehicles.
The principle of the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would force your car's ignition switch into the "on" position using a flat screwdriver or even make use of hot-wires to bypass the system completely. Transponder chips have dramatically reduced these types of thefts.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. The antenna is programmed with the 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.
Some vehicles only recognize certain type of transponder chip according to the manufacturer. This is why it's crucial to make sure that your locksmith for automotive has the right equipment to program your car's keys and fobs properly.
A reputable locksmith for automotive will utilize a multi-vehicle programmable tool that can be used on a variety of different automobile models and manufacturers. This is a less expensive solution than buying separate tools for each brand of vehicle. They are not as common but there are automotive key programming tools that can only work on a particular type of vehicle. The best automotive locksmiths will have the appropriate tools to work on any type of vehicle, so make sure you choose a reputable firm with these kinds 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. They also have buttons that you can push to activate features such as door locks, trunk release or control of the fuel flap. Some fobs also have additional functions that can be controlled with the press of a button like the "smart" key fob that lets you get your car into parking spaces that are difficult to access as you would with a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the help from a user guide, but you'll need to call an automotive locksmith in the event that yours has stopped working. This is because an expert locksmith has the specialized equipment and access to the programming tools required to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs come with security features to make it harder for attackers replicate and clone the signals they transmit. Certain key fobs come with pseudo-random code generators which generate a different 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 instances, you can purchase an alternative key fob from the dealer or from another retailer and have it programmed by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customer's keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, automotive locksmiths strongly discourage using them as they're more likely to perform poorly or not at all. Instead, they suggest buying fobs specifically designed for your vehicle, so that you can be sure they'll work properly and are less prone to issues like interfering or not working. This will save you money in the long run by reprogramming keys for cars avoiding costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has advanced considerably and today's vehicles need computers to function. One of the most important components of this technology is a transponder chip that must be programmed into the vehicle by a locksmith or dealer/mechanic in order to work. These key fobs are equipped with security features that prevent hot-wiring, like in a movie. The car will not start if the keys are not correct.
Key fobs are a little more complex than the mechanical keys and are the reason they are usually in the hands of a skilled professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the key type, but they typically run between $85 to $400. This includes the cost of labor to program the keyfob, as well as any replacement parts.
These car key fobs are more complicated because they use software that interacts with the computer onboard of the car. The software blocks unauthorized access by allowing the key to function only if it's been programmed for the specific car. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car to function.
The most common way to accomplish this is using the car key programming tool that is compatible with the model of the vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming tool can either be an inexpensive handheld device or a fancy one that can do many things that go beyond key programming (like reading and cloning EEEPROM files in the ECU).
Some people attempt to program their keys on their own using these tools. However it's best to leave this task to a professional auto locksmith. If you're not familiar with the aspects of the various software systems, it's very easy to accidentally alter settings that could cause damage to the vehicle. The most important thing to remember is that a professional with experience can help you avoid these problems.
On-Board programming
If your car is old enough that you'll have a traditional metal key to use to unlock the doors and turn on the ignition. However, modern cars are equipped with a transponder chip that must be recognized by the car's computer system to begin. This is an additional layer of security that stops car thieves from starting a car stolen and driving off with it. A locksmith who is certified will have the right tools and software to program a new key that works with your car's security system.
Your locksmith will have to acquire an uncut key that is that is compatible with the vehicle's model and make. Once the key is in your possession the locksmith will connect the scanner that is used for programming to your car's diagnostic port. This will put the vehicle into the mode of programming that allows the locksmith to add a new key to the system.
To accomplish 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 this code and include it to the list of keys that are authorized. In some cases the scanner will also remove keys that have been stolen or lost.
You can also program new keys using EEPROM. It is more complicated and requires a deep understanding of electronic systems. This is why it's best left to a professional who has extensive experience working on these types of systems.
Locksmiths can program a key quickly by using onboard programming. If everything is done correctly it could take just one minute. If the key isn't in the right situation or the procedure is not adhered to, it could take up to a half hour.
There are a variety of key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due their wide selection of vehicle models. However, neither can be programmed for every vehicle in existence. Additionally, these devices are quite expensive. It is best to buy a programmer which will receive regular updates from the manufacturer when new technologies are developed. Your computer's programming software will soon become outdated if you don't do this.
