How to Replace the Battery in a FAW-Volkswagen Magotan Key?

[MacMakayla]

Method for replacing the battery in a Magotan key is as follows: 1. Remove the spare mechanical key, then take off the silver decorative piece at the bottom of the key. 2. Use your thumb to push firmly towards the hidden button side to slide off the silver decorative cover. 3. Open the rear cover of the key, pry off the back cover, remove the old battery, replace it with a new one, and then reassemble following the original steps. Below are some relevant details: 1. The battery life in a car remote key is typically around 3 years. When the battery runs out, you need to open the key casing to replace it with a new one. 2. The Magotan key operates via coil induction. During the unlocking process, the vehicle's RF transceiver verifies if the key matches to determine whether the engine can be safely started. 3. In special cases where the key battery is dead, the car can still be started normally. However, using the mechanical key to open the door in this scenario will trigger the anti-theft alarm, resulting in a beeping sound from the front of the vehicle. Inserting the key into the ignition switch will allow the chip to match successfully, stopping the alarm. This serves as the final security mechanism.
