How can you lock your Renault laguna the key card is broken?

If your Renault Laguna's key card is broken, you can lock the vehicle manually using the physical key, which is usually hidden inside the key card. To access it, slide the release button on the key card to extract the metal key. Use this key to lock the driver's side door. Alternatively, you can use the vehicle's central locking system from inside to secure all doors.
