Compare of Transponder key and a Remote Key Fob

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.

Transponder key and a Remote Key

Remote keys

Most people refer to remote keys as key fobs, and if you’ve got one of those with a couple of buttons on it, that’s exactly what we’re talking about. Remote keys are designed for user convenience rather than security. Remote keys allow you to lock and unlock your car at will, which is much more timely and easy than putting your metal key in the lock every single time.

Transponder keys

Remote transponder key has a control chip inside of the unit that is a vital part of a vehicle’s security system, which provides an extra level of anti-theft. Without it, the engine cannot start and the alarm system cannot be disarmed, only an experienced auto locksmith trained in transponder technology can help.

Most cars today come with remote keys, instead of “just” a traditional flat car key, the latest automobile models are equipped with key-less transponder locks, thus eliminating the need for physical car keys altogether.

Some types of remote control keys have the remote unit mounted on the head of the key and is basically a separate piece, and others have the remote unit built into/onto the key. If the remote is not functioning, either the battery is dead or the unit is broken, then the remote controlled locking system can be bypassed using the traditional key to unlock the vehicle without causing the alarm to go off.
