Car Keys and Remotes

•Main Types of Car Keys and Remotes:
•Traditional mechanical key: A basic metal key without electronic components. It works manually to open the doors and turn the ignition cylinder in older vehicles.
•Transponder key (with chip): Features a plastic head that hides a programmed microchip. The car must read the chip’s code through the immobilizer to allow the engine to start.
•Traditional remote control / Key fob: A plastic casing with buttons to lock, unlock doors, open the trunk, or activate the alarm from a distance using radio frequency signals.
•Flip or “switchblade” key: Combines a remote control with a metal blade that folds into the casing via a spring-loaded button.
•Fobik: A thick plastic remote (very common in brands like Chrysler, Dodge, and Jeep) that includes buttons and a removable emergency key.
•Smart Key or proximity key: Does not require inserting a key into the lock. It uses proximity sensors (RFID or NFC) to automatically unlock the doors when nearby and starts the engine using a push-button start. It features a hidden mechanical emergency key.
•Key Card: Similar to a thin credit card, it performs access and proximity functions without the shape of a traditional remote control.
•Digital Key: A smartphone or smartwatch application that communicates with the vehicle via Bluetooth or NFC.
