Why Car Key Programmed Is More Tougher Than You Think
Why Get Your Car Key Programmed?

Many people should have their car keys programmed. If you have children who press the button too many times or you've lost your keys, then the remotes need reprogramming.

Some auto locksmiths and dealerships have the equipment needed to do this. They can also copy your key if possible.

Transponder Keys

Transponder keys can also be referred to as chip keys or smart keys. Transponder keys contain microchips that store and transmit information, which helps to protect your vehicle from being stolen. The microchip transmits a unique identification code every when the key is turned in the ignition. Once the ID code matches the one in your car's computer the immobilizer will be turned off, and your engine will start.

This is a much more advanced security option than non-transponder keys that do not have a chip inside and are not compatible with all modern anti-theft systems for cars. Transponder chips were introduced to cut down on car thefts, and they have proven successful - car thefts have dropped significantly since their introduction.

When the key is inserted into an ignition the small antenna known as an inductive coil located on the transponder on the car key will be powered up. The transponder will transmit the radio frequency signal along with a unique "password" to the vehicle's anti-theft device. If the password is correct, the car will disable the immobilizer, allowing you to start your vehicle.

If the password isn't correct, the immobilizer will remain in effect and the engine will not start. This is an excellent way to prevent car theft because even if the key could be duplicated, thieves cannot access the correct code to fool your car into starting.

The only drawback to transponder keys is that it is not compatible with mechanical non-transponder keys. These car keys work by physically moving lock mechanisms on doors or the ignition cylinder. For instance, GM's VATS system (Vehicle Anti-Theft System) requires the correct amount of resistance to turn the cylinder.

These traditional non-transponder keys can still be copied at locksmiths, but the criminal will have to manually move the locks in order to start the engine. He will likely need a special transponder key programming device to accomplish this. This is why it is imperative that you should always contact an expert locksmith, like Pop-A-Lock, when you require a new car key or transponder cut.

Electronic Key Fobs
