Transponder Chip Keys: What They Are & How They Work.

If you have recently replaced your car key, you have noticed it is no longer a quick, cheap, “cut to replace” process. Instead, many vehicle manufacturers have begun using transponder chip keys for cars to ensure vehicular safety. While this relatively new key technology is great for preventing theft, it also makes replacing lost or broken keys difficult unless you know a locksmith with the correct transponder chip key programming equipment.

What is transponder chip key programming?

The technology for transponder chip key programming was developed during World War II, though it was unpopular until the 1990s. Cars with transponder chip keys or an immobilizer have an antenna coil in the ignition. Once the key is inserted and turned, the ignition coil creates an electromagnetic field. In the plastic head of modern chip keys for cars, a transponder ‘chip’ communicates with this electromagnetic field, verifying if the key is correct. If the transponder chip key programming is not programmed with the correct code, the immobilizer will prevent the car from starting.

Why are chip keys for cars so difficult to replace?

Chip keys for cars are tough to replace because transponder chip key programming involves a unique code programmed during manufacturing. When the key is lost or stolen, you no longer have a key with the code necessary to start the car. Even if you have a metal replacement cut, the missing chip will prevent the car from being used. Many auto dealers try to remedy this by replacing the entire computer system, which can cost hundreds or even thousands of dollars. However, if you find a quality locksmith, you do not have to fork over all that extra cash for a new car computer. Instead, auto locksmiths can offer key reflashing services and chip keys for cars.

What if I lose my transponder chip keys?

If you lose your transponder chip keys for cars, there are options other than a costly tow to the dealership or replacing your auto computer. Some Chicago locksmiths offer key reflashing services. Here, the locksmith relocates and removes the computer system of the car. Then, they find the chip for transponder chip key programming. With the right transponder chip key programming equipment, the computer can be hooked up to a specialty locksmith program and go into ‘learning mode’. Now, locksmiths use transponder chip key programming to create a new key and code.
