Facts And Tips About Transponder Keys

Most, but not all modern cars have keys that have to be programmed using RFID transponder technology

. Most cars made since the mid-1990s have transponder keys. There are lots of different ways of programming these keys, and most of the time you need a professional from a car dealership or you'll need a professional locksmith to do this.

To make a new key, a locksmith can use a key code to automatically cut a key to factory specifications. The process uses a machine that has instructions in its memory to perfectly cut all kinds of keys based on their key code. Some car models make it difficult, however, to access this numerical code. Many Asian cars have the key-code displayed in at least one of the locks - often in the passenger door lock. Authorized dealerships can get you the key code as long as the car is not too old. Some key-codes are no longer available, unfortunately.

If your key code cannot be found or easily accessed, and you need replacement car keys, you may have to contact a car locksmith to decode the locks. So you can see why it's important that you choose a Chicago area locksmith who has experience making replacement car keys for a large variety of car models. It's worth checking to see if you can find your car's key code. If so, write it down and save it in a safe place, because it can save you trouble if you need to replace your car keys.

Chicago local locksmiths can also replace keys using the car's VIN. However, if your ignition or your locks have been changed, replacement car keys made using the key code or the VIN might not work on the new locks or ignition.

People often wonder if they transponder keys can get deprogrammed. Well, they may stop working, but often it isn't the key itself that has the problem. Sometimes, a key suddenly stops working and the "theft" light comes on in the car. While the key might not be programmed correctly, more likely the car's computer or electrical system is where the problem is located. Often you need to have an automotive electrician look at your car rather than a locksmith if your transponder keys suddenly stop working.

Your best security measure for coping with lockouts is to have a spare set of car keys made before you need them and store them with someone trustworthy who's easy to get hold of should you lose your keys. It's no fun starting from scratch trying to find a Chicago locksmith late after a night out when your keys have gone missing. When you get your spare keys made, you have the time luxury of being able to check out several locksmiths so that you can find one that's trustworthy, professional, and easy to work with. Once you find that locksmith, program the number into your phone for easy access should you find yourself in a lockout emergency.
