Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian automobile manufacturers share their programming protocols with auto tool makers to allow them to develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Transponder chips are found in a lot of modern cars to stop theft of cars. These are microchips in the form of computers that emit low-level radio signals. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has been a huge success in preventing theft of cars. It also saves many car owners a significant amount of money because they don't have to buy new their vehicles.
The fundamental idea behind the transponder system is to make it impossible for thieves to start your car without a key. In the past, thieves would simply push your ignition switch to the "on" position with a flat screwdriver or even use hot wires to disable the system completely. Transponder chips have drastically reduced the number of thefts.
When you place the transponder key into the ignition, the signal is received by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow and power the starter to begin the engine.
Based on the manufacturer, certain vehicles can only accept a specific type of transponder chip. Therefore, it is essential that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have a multi-vehicle key programming tool that can work on many different models and manufacturers of cars. This is a less expensive alternative to purchasing specific tools for each type of vehicle. There are also specialised automotive key programmer devices that are only suitable for specific models of vehicles however, they are less common. The best automotive locksmiths are equipped to work on any vehicle. Make sure you select 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 unlock doors and begin the engine with the push of a button ignition. You can also press buttons to activate features like trunk releases, door locks or controls for the fuel flap. Certain fobs can be controlled with the press of buttons. For example, a "smart key" that allows you summon your car to parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the assistance of a user's manual however, you'll typically require an automotive locksmith to get a new one programmed in case yours stops working. A professional is better equipped to connect the computer of your vehicle via the OBD port located under the steering wheel.
Most key fobs today come with security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random generators that generate a new unlock code every time you press the button on your key fob. This is to prevent attackers from capturing and replaying the unlock signal to gain access to your car.
In most instances you can buy a replacement key fob from the dealership or another retailer and then have it programmed by a locksmith for your vehicle to fit your particular vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with third-party companies that produce the tools used by locksmiths for programming their customer's keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them as they're likely to work poorly or not at all. Instead, they suggest buying fobs designed specifically for your vehicle so that you can be sure they'll work properly and are less prone to issues like interference or incompatibility. This will save you money in the long run by avoiding costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers
Automotive technology has come a long way 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 an expert locksmith or dealer/mechanic in order to function. These key fobs are equipped with security features to prevent hot-wiring, like in a movie. The car will not start without the correct keys.
These key fobs are a bit more complex than the traditional mechanical key, which is why you'll usually find them in the hands of an expert, professional auto locksmith. The cost of a key fob will vary depending on the car model and the key type, but they typically run between $85 and $400. This includes the labor cost to program the keyfob, as well as any replacement website parts.
These car key fobs are more complex due to the fact that they use a software system that works with the onboard computer of the car. The software prevents unauthorised access by only permitting keys that have been programmed specifically for a particular car to function. If you change your keys, you'll need to program the new key fob to the car to allow it to function.
This is done by using a programming tool for car keys that is compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. The key programming tool could be a simple handheld device or a more expensive one that can perform many things beyond just key programming (like reading and cloning Eeprom files within the ECU).
Although some people might attempt to program their own keys using these tools, this is an activity best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's easy to accidentally alter settings that could potentially damage the vehicle. The most important thing to remember is that a skilled professional can assist you in avoiding these problems.
On-Board Programming
If your car is old enough that it has a key, it might still come with a metal key that can be used to open doors and turn off the ignition. Modern cars come with a transponder chip that must be recognized by the car's computer system to allow it to start. This adds another layer of security that prevents thieves from stealing the car and then driving off with a stolen car. A locksmith certified has the tools and software needed to program a key that can work in your car's system.
Your locksmith will first need to acquire a key blank that is that is compatible with the vehicle's make and model. Once your locksmith has the key, he will connect the programming scanner to the diagnostic port of your vehicle. 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 programming scanner will communicate with the car's computer system to transmit a specific code. The computer will detect the code and add it to the list of keys that are authorized. In certain instances the scanner will be able to remove lost or stolen keys from the system.
You can also program new keys using the EEPROM. It is more complicated and requires a thorough understanding of electronic systems. It is best to leave it to a professional with experience with these systems.
Onboard programming is the quickest way for a locksmith to program the new key. When everything is done correctly it could take just one minute. If the key isn't in good working order or the procedure isn't being followed exactly, the process can take up to half an hour.
There are many different key programmer scanners which can work with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular among locksmiths due to their wide range of models for vehicles. However, no system will be able to program every vehicle in existence. They are also expensive. It's a good idea purchase a computer that receives regular updates when the manufacturer introduces new technologies. Your machine for programming will quickly become outdated if you don't take this step.
