[MacMadeline]

To replace the battery in a Buick Excelle key, follow these steps: 1. Pry open the key casing: Use a tool to separate the remote key into two sections along the seam, then detach the back half. 2. Remove the circuit module: Gently turn it over to access the circuit module, where you will find the key battery. 3. Install the new battery: Remove the old battery and insert the new one. Reasons for car key failure are as follows: 1. Key issues: During daily use, car keys may run out of battery. Pay attention to the usage method when driving, keeping the locking and unlocking distances shorter, as longer remote distances consume more power. Avoid pressing the remote key multiple times when locking the car. 2. Car issues: When the car battery is low on power, the car key may also become unresponsive. It is important to monitor the car battery's charge during use to avoid running out of power while driving, which can affect normal vehicle operation.
