This process is similar to how you would program a new remote control to work with your TV. The reason for this is that the keys of most modern cars contain transponder chips that communicate with the computer system inside the car to switch it on and off and lock the doors, and so on. The key may have buttons to open doors or close them, trigger alarms, and so on, depending on the make and model of your vehicle. The first step is to find out which key blanks and tools you'll need for your specific vehicle. This will help you determine whether this is something you could do by yourself or if a professional should be called. Follow the directions that came along with your key fob, or transponder chip, to start the process. It is important to remember that there are some models of cars that will only allow the dealership to make a replacement key. In this situation, you will be required to contact them for help. They can design an entirely new key and program it to your vehicle so that it will start the car the same way as the original key did. Another frequent question asked by people is whether they can reprogram a key that has already been programmed to work with their car. It is possible in some cases but the majority of manufacturers will only allow the key to be used with vehicles they own. This prevents other individuals from stealing your vehicle simply by changing the code of a blank key to work. A professional is the best choice in this situation.

Key Fobs Key fobs permit you to combine a variety of functions into a portable package. They make it possible for vehicle owners to control door locks, ignition systems, and more with the press of a button, or a proximity scan.

Fobs can also be used to provide controlled entry for commercial and industrial buildings. By connecting programing car keys to a central computer, facility managers can program RFID readers and assign access levels for guests, employees or customers. While most cars are designed with security in mind, there are still people out there who want to take advantage of security weaknesses. Some criminals are able to hack into the car's security system and drive off with it by using a piece of hardware that is cheap. Fobs come with several security features that are built-in to guard against such attacks. Specifically, they transmit passcodes that change each time the fob gets activated, and then automatically expire after a set period. Fobs are also designed to be safe from wireless hacking. Modern key fobs are fitted with advanced encryption protocols that block hackers from stealing codes. They also utilize RFID readers that have a unique ID to prevent multiple fobs from gaining access to the same area at once. Before you attempt to re-program your key fobs, check the owner's manual for specific instructions for your vehicle. The general process for reprogramming is the same for all major models, but they may differ in small details. In some instances, you may need to contact a locksmith for assistance. The first step is to remove the old fob from your car and safely store it. You'll need to have all of your other fobs in order. After you've completed this, get into the driver's seat and close all doors, with the exception of the driver's side door. This is necessary to activate your car's reprogramming function. With the engine of your car switched off, place your new fob in the window on the driver's side and press the lock button. You should hear a click sound within a couple of seconds. This indicates that your fob was successfully reset. Repeat the process for all of your other fobs. Transponder Chips Transponder chips are located in the top part of modern smart keys, fobs and remotes. They permit your car to start whenever you make use of them. The chip transmits an identification code to the car's engine immobilizer and informs it that it's a valid key and not a stolen one. The chip transmits this ID code by radio to the computer of the car. If the ID code matches with the one stored in the car's memory, the car's security system will turn off the immobilizer and allow the engine start. The security light on the dashboard will go out after this has occurred. If you own a brand new car with transponders, but it does not seem to recognize the new key, you can call an expert locksmith to cut and program a replacement for you. It is important to ensure that the replacement key is a clean one and that you purchase it from an authorized locksmith. Secondhand keys, particularly ones that have been cut prior to they can't be cut again and might not be compatible with your car. It's not as easy as copying a mechanical key to duplicate a transponder as it requires specific programming. It also requires a car key programmer that is compatible with the particular model of car. If you have a spare key, it will likely already contain a transponder chip, but you must verify this before you pay to duplicate it. The majority of car manufacturers have made their systems more secure since 1995 to prevent thieves from hot wiring a car's ignition and driving away with the ignition. However, thieves are still able to steal a car by using a laser to “read” an ID code on a stolen or misplaced smart key. They then start the engine of your vehicle. It is crucial to keep an extra key to avoid theft. A professional automotive locksmith can reprogram your transponder chip or smart key in just a few minutes with a specific device for programming. They will enter the unique codes that your car has stored and then use their tablet to make the new key work with your system. This is a very useful service and provides greater protection than a normal key replacement. Locksmith Services Modern keys are more than a piece metal. They are now loaded with technology that allows them to unlock your car and communicate with the ignition chip. If keys become damaged or lost, it isn't enough to simply replace them. They have to be programmed so that they emit the correct signals to unlock the car and communicate with the chip. It is this type of work that only a locksmith with experience can undertake. There are numerous locksmith services that provide key reprogramming. It is essential to choose your locksmith with care. It is also important to ensure whether the locksmith is licensed in your state, and also that they carry the appropriate insurance to cover any damage or loss that could occur.

In the past, locksmiths would use a blank key and move it around a bit (this works only on older locks that have notches). However, it's more difficult now. Locksmiths are equipped with advanced tools and software to program a new key to match the vehicle's existing programming. The process of reprogramming involves connecting the computer of the locksmith to the onboard diagnostics port (usually under the dashboard) of your vehicle. Then they have to enter a particular code to enter the programming mode. Entering an unique code that matches the make and model of your car is how you do it. You can locate the code by searching online or consulting your owner’s manual. Once they are in the programming mode the locksmith will then insert the key into the ignition and then turn it to the “On” position without turning on your engine.
