How It Works



A remote car key, often referred to as a key fob or remote keyless entry (RKE) system, works by using radio frequency (RF) communication to remotely control various functions of a vehicle, such as locking and unlocking the doors, opening the trunk, and sometimes even starting the engine.

    1. Key Fob: The remote car key is a small handheld device that typically contains buttons for different functions, like lock, unlock, trunk release, and panic alarm.

    2. RF Transmitter: Inside the key fob, there's an RF transmitter, which generates a specific radio frequency signal when a button is pressed.

    3. Vehicle's Receiver: The car is equipped with a receiver unit, usually located in or near the vehicle's dashboard. This receiver is programmed to recognize and respond to the specific RF signal sent by the key fob.


Whether you need a new key, key programming, or assistance with a car lockout situation, we can provide the expertise and assistance you require. A car key transponder, also known as a transponder key or simply a “chip key,” is a key that contains a small electronic chip (transponder) embedded in the plastic head of the key. The transponder key is designed to work with the car’s immobilizer system, which is a security feature used to prevent unauthorized starting of the vehicle. Here’s how a car key transponder works:

  1. Code Matching: The key fob and the vehicle are paired using a unique code or encryption. When you press a button on the key fob, it sends a signal containing this code to the vehicle’s receiver.

  2. Authentication: The vehicle’s receiver checks the incoming signal against the stored code. If the code matches, the receiver recognizes the key fob as authorized and authenticates the command.

  3. Function Activation: Once authenticated, the receiver activates the requested function. For example, if you press the “lock” button, the receiver will lock the car doors. If you press the “unlock” button, it will unlock the doors.

Authentication: The receiver or antenna sends the signal to the car’s onboard computer, often referred to as the Engine Control Unit (ECU) or Electronic Control Module (ECM). The ECU compares the received signal with the stored codes in its database.

Matching Codes: If the transponder chip’s identification code matches one of the codes stored in the vehicle’s database, the ECU considers the key to be legitimate and authorizes the vehicle to start.

Engine Start: If the transponder chip is authenticated, the ECU allows the engine to start. If there is no match or if the signal is invalid, the engine will not start, and the car remains immobilized.
