Transponder keys are a type of car key that has a microchip inside that can communicate with the car’s immobilizer system. The microchip sends a low-level signal to the receiver near the ignition, and if the signal matches the code programmed in the car, the car will start. Transponder keys are more secure than non-transponder keys because they prevent car theft by hot-wiring or using the wrong key.
Transponder keys can be copied by a locksmith or a dealership, but they need to be programmed to match the car’s code. Transponder keys are more expensive than non-transponder keys because they require more technology and work to make and program.
Laser cut car key: This is a thicker key that has matching teeth and grooves on both sides. It is laser-cut to make it more difficult to copy. It may also have a remote handle with a transponder chip inside.
Flip-style car key: This is a compact key that folds into the key fob when not in use. It may also have a transponder chip inside the fob.
Remote car key combo: This is a key fob that has a transponder chip and buttons that can lock or unlock the doors or activate a panic alarm. The key portion does not have a chip and can be used as a backup.
Encrypted car key: This is a type of transponder key that has an extra layer of security by encrypting the code that is sent to the car. It makes it harder for thieves to intercept or clone the signal.
