Why Get Your Car Key Programmed?
Many people need to get their car keys programmed. If you have kids that press the button too often or you've lost your keys, then your remotes require reprogramming.
Some dealerships and auto locksmiths have special equipment to do this. They can also clone an existing key, if that's possible.
Transponder Keys
A transponder key is another name for an electronic car key, also sometimes referred to as chip keys or smart key. Transponder keys contain an embedded microchip that can store and send information, which helps to prevent your vehicle from being stolen. The microchip transmits a unique identification code each time the key in the ignition is turned. When the ID code matches in your car's computers the immobilizer is disabled and your engine will start to run.
This is a far more sophisticated security method than non-transponder keys, that do not have a chip inside and are not compatible with most modern anti-theft devices in cars. Transponder chips were introduced to cut down on car thefts, and they have been a success - car thefts have dropped substantially since their introduction.
When the key is inserted into the ignition the small antenna known as an inductive coil on the transponder of your car key will power up. The transponder then transmits the radio frequency signal which contains the unique "password". This is sent to the anti-theft device of your vehicle. If the password is correct your car will deactivate the immobilizer, allowing you to start the vehicle.
If the password is wrong the immobilizer will remain active and the engine will not start. This is a great way to protect your car from theft because even if the key can be duplicated, thieves won't have access to the correct code to fool your car into getting started.
The only downside to transponder keys is that it isn't compatible with mechanical non-transponder keys. These kinds of keys for cars work by physically moving the lock mechanisms on doors or the cylinder that controls the ignition like GM's VATS (Vehicle Anti-Theft System) system which requires the correct amount of resistance to turn the cylinder.
The non-transponder keys of the past are still able to be copied at an locksmith, however the thief will have to manually move the locks to start the engine and will likely need a special transponder-programming device to do so. This is the reason that you should always consult a professional locksmith such as Pop-A-Lock, if you require a new car key or transponder cut.
Electronic Key Fobs
A key fob emits a signal which activates your car's locking system which allows you to unlock the door and access your vehicle. It also lets you control the alarm and trunk according to your vehicle's features. The microchip inside the fob transmits codes which are then interpreted by the receiver. The code corresponds to a certain frequency, and if the reader detects that frequency, it transmits an instruction to your lock to start working.
If you're using fobs for commercial purposes it is possible to integrate it into an existing security system. This can add additional levels of security. Fobs are able to be immediately blocked when they're stolen or lost, which is an added security measure in a business where a key might fall off on a desk or be taken by unauthorised individuals. Fobs are also cloned and created as unauthorized copies floating around with your security code, making your vehicle vulnerable to unauthorized access.
Fobs are extremely useful and can be used to unlock your doors without the need of a traditional key. It is not difficult for a common person to program a fob, even though it requires some knowledge of technology. Fobs can be programmed by using a special tool or following the instructions in the vehicle's user manual.
The process of reprogramming your key fob is similar to the process used by all models, and you will often find more detailed information regarding your specific model in the owner's manual or on the manufacturer's site. However, it is important to note that these steps might not work for all models, and if you encounter difficulties you might consider consulting with your dealer or calling an expert locksmith.
Begin by stepping into the driver's seat and putting the key fob you want to reprogram in your hands. Make sure that your door is shut and there are no other keys in the ignition. Press and hold the lock on your fob for a few seconds until you hear the chime or the sound of the locks turning. This means that you have entered program mode. Repeat these steps as necessary to program other fobs.
Enhanced Security
Transponder keys offer an additional security layer that is not available with traditional key fobs. Transponder keys are less likely to be taken by thieves since the chip only matches the code with the immobilizer inside your car. If it fails to do so it will cause the vehicle to refuse to start, making the process of stealing your car much more difficult.
Unlike old-style keys the modern transponder key chips are not part of the lock itself but are located in a special area inside 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 on your vehicle and the car can be started. Modern keys must be programmed correctly to work.
While it is possible to reprogram your own car keys, this process can be very dangerous and should be left to experts. It's not common for a novice to attempt this, only to find that the key doesn't function properly or causes damage to the immobilizer system of your vehicle. A professional locksmith for cars or dealer will have plenty of experience in these types of situations and can help you out in the most efficient way possible.
Beyond this, many advanced anti-theft systems depend on the proper programming of your key to operate effectively. It is recommended that you have your keys reprogrammed as soon as possible after you lose them or have lost them to ensure that thieves will not be able to gain access to your vehicle.
