Why Get Your Car Key Programmed? Many people should have their car keys programmed. If you have kids that press the button too often or you've lost your keys then the remotes need reprogramming. Some dealerships and auto locksmiths have the tools needed to accomplish this task. They also can clone your existing key if it's possible. Transponder Keys A transponder keys is a different term used to describe an electronic car key. It is sometimes referred to as a chip key or a smart key. programming car key contain an embedded microchip that can store and transmit information, which helps to protect your vehicle from being stolen. The microchip transmits a unique identification code every time the ignition is turned. If the ID code matches the code in the car's computer, the immobilizer is disabled and the engine will start. This is a much more advanced security measure than non-transponder keys, which do not have chips inside and are not compatible with most modern anti-theft devices in cars. Transponder chips were used to decrease car thefts. They have proven to be hugely successful. When the key is inserted into the ignition an antenna that is small, called an inductive coil that is located on the transponder of your car key will be powered up. The transponder transmits a radio frequency signal containing a unique “password”. This is transmitted to the anti-theft system in your vehicle. If the password is correct, the car will disable its immobilizer and allow you to start the engine. If the password is incorrect, the immobilizer remains active and the engine won't start. This is a great way to prevent car theft since even if the key could be duplicated, a thief will not have access to the correct code to fool your car into starting. The only drawback to a transponder key is that it isn't compatible with mechanical keys that are not transponder. The keys for cars work by physically adjusting lock mechanisms on doors or the ignition cylinder. For example the VATS system from GM (Vehicle Anti-Theft System) requires the correct amount of resistance to turn the cylinder. These traditional non-transponder keys are still able to be copied at an locksmith, however the criminal will have to manually move the locks to start the engine. He will likely require a transponder key programming device to do this. This is among the main reasons that it is advised to contact a professional car locksmith such as Pop-A-Lock whenever you need a new transponder keys cut or a car key that has been programmed. Electronic Key Fobs A key fob emits a signal to activate the locking system in your car, allowing you unlock your door and access your vehicle.

The code corresponds with an exact frequency. If the reader detects this frequency, it will issue an instruction to your lock. If you're using a fob in commercial settings, they can be integrated into your existing security system to add additional levels of protection. Fobs are instantly blocked when they're stolen or lost and add an additional layer of security for a business. A key can fall from a desk in an office that is crowded and taken home uninvited.

Fobs are typically programmed with the aid of a specific software tool or by following the instructions in the user manual for the vehicle. The process of reprogramming your key fob is similar to the process used by all models, and you will often find more detailed information about your model in the owner's manual or on the website of the manufacturer. However, it is important to keep in mind that these steps might not work for all models. If you have issues, it might be worth talking to your dealer or an expert locksmith. Start by getting into your driver's seat and holding the key fob you wish to re-program in your hand. Make sure your door is shut and there are no other keys in the ignition. Press and hold the fob's lock for a few seconds until you hear the chime or the sound of the locks revolving. This means that you have entered program mode. Repeat these steps if needed to program other fobs. Enhanced Security Transponder keys add an additional security feature that isn't always available with traditional key fobs. Transponder keys are less likely to be stolen by thieves because the chip can only match the code with the immobilizer inside your vehicle. If it does not then the car will not start which makes it harder to take. Modern transponder keys do not include a chip inside the lock, but rather in a specific part of the key. When you insert the key into the ignition a radio signal is transmitted to the transponder. If the code is correct it will match with the immobilizer in your vehicle and the car can be started.
