What does 'chip key' mean? How do I know if I have a 'chip key'?

A 'chip key' usually refers to one of two types of keys that have an electronic component to them. The first has a visible chip located on the key and is normally on a General Motors vehicle. This is called a Passkey system or VATS (Vehicle Anti-Theft System). These appeared in 1986 on the Corvette and certain Cadillac models. The second type refers to a key with an RFID (Radio Frequency Identification Device) located in the head of the key, these type are not normally visible unless the bow or head of the key is transparent.

Both of these systems add a layer of security to the vehicle by having the vehicle check the value of the electronic component on the key before allowing the vehicle to be started. Some systems prevent the vehicle from attempting to crank while others prevent the fuel system from working.

If you have the first type, VATS it is obvious because you can see the chip on the key. The other type is more difficult to determine because the RFID is embedded in the plastic head. The only real way to know for sure is to use an electronic device designed to detect the chip. You could destroy the key to see it but that would likely ruin the key and would be costly to replace.

One thing is for certain, you should always have at least three of these keys. Why three and not just two? In many vehicle systems you can program in a new key yourself but have to have at least 2 working master keys for the system to do it. If you get down to 1 working key then you will have to contact a service person such as a locksmith or automotive security specialist to program they key as special diagnostic equipment is needed to complete the task.

Does this really stop thieves? This is a percentage question, from an insurance carriers perspective the 'chip keys' or transponders have have eliminated a great deal of vehicle theft. But no security system can stop a well prepared thief, especially if they own a helicopter and just fly off with the car. Interestingly enough though, even if a vehicle is taken by force such as with a tow truck or helicopter the thief still has to 'restore driveaility' at some point by making the keys or bypassing the security system. Yes, they can do it but it is certainly a deterrent and adds real cost to their thieving operation.

If all keys are lost for a vehicle that has a chip on the key, you usually have two options: The dealer or a locksmith. Because the keys have to be programmed you cannot normally go to a dealer and pick up a key that will work the vehicle. You will usually have to have the vehicle TOWED to the dealer for them to service it. Most locksmiths however will come to the vehicle with all of the necessary machines, transponder key blanks and equipment to cut a key on-site to get you on your way immediately.

If you ever find yourself in need of extra keys, replacement keys or replacement remotes/key fobs such as found on newer vehicles make sure you call a bona fide locksmith. Look for a Pop-A-Lock(r) provider or an ALOA (Associated Locksmiths of America) locksmith. Always ask for the EXACT FINAL PRICE that you will have to pay including service charges, labor or any other 'fees'.
