1 Answers
To replace the battery in a Ford Escort key, follow these steps: 1. Press the button on the back of the key; 2. Slide the back cover forward to open it; 3. Replace the battery in the slot and reattach the back cover. Functions of the key: 1. After turning off the vehicle, long-press the lock button on the remote key to close the windows; 2. The red horn-shaped button on the key serves both as a car locator and an emergency signal; 3. Features an automatic trunk opening function. Key principle: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the locking or unlocking action.
