What is the Difference between a Transponder and a Remote Control Key

The most basic difference between the two is that a transponder unlocks a vehicle without using a physical locking mechanism or key, and the engine will not start without it. A remote key can also unlock the vehicle’s doors, but if the remote control unit does not function, the traditional flat key can be used.

Without it, the engine cannot start and the alarm system cannot be disarmed, only an experienced auto locksmith trained in transponder technology can help.
