Understanding Transponder Keys

Transponder keys are keys designed to transmit radio signals to a remote receiver from a handheld device. They are typically used to start and unlock vehicles, though they are also used in gate openers and systems with keyless entry. Each transponder key is programmed to start only for a specific vehicle. This reduces the chances of a vehicle being stolen. This particular type of key was introduced in 1995.

How it Works in Vehicular Use

The transmitter has a small microchip in the key, and this has a unique serial number, which is set during initial programming. In case a person wants to start or unlock the car, the chip sends a signal to the car to validate the serial number and turn the immobilizer off. If the car does not recognize this, it will not start. Transponder key is commonly used for latest car models. Cars can be retrofitted to for this system but it can be costly since it will require reprogramming the electrical system and making a new key. A professional locksmith can do this, but an auto dealer may not easily release programming data.  It is a good idea to keep two copies of transponder keys since replacement can be expensive. An auto locksmith can provide replacement if needed.

It is also possible for drivers to program their blank keys but the process may vary by vehicle model. It is quite common for drivers to lose or break car keys.

Besides vehicular use, transponder technology is used in other applications, such as garage doors, wireless alarm system, gate opener, and wireless home entry systems. Recent advances in technology led to keyless entry and starting system development. With these, signals are sent out continually from the fob, and it is in range of its receiver. The car can be started or doors will be unlocked using a push-button ignition. The door automatically locks and an immobilizer is activated if the key is removed from an active range. In the next few years, the technology is expected to continue to develop.
