# Step 5: Program Door Locks

Once you have [set up door locks](/latest/device-and-system-integration-guides/assa-abloy-visionline-access-control-system/visionline-acs-setup-instructions/developing-and-launching-your-visionline-mobile-key-app/launching-your-visionline-mobile-key-app/step-4-set-up-door-locks-with-ble-profiles.md) in the Visionline application, use the Lock Service 3G application to program the door locks themselves. When you program a lock, you download the identity and settings for the lock from Lock Service 3G to the lock.

This process consists of the following basic steps:

1. [Configure the Visionline application to download door lock data to Lock Service 3G.](#configure-visionline-for-lock-service-3g)
2. [Configure Lock Service 3G to connect to the Visionline server.](#configure-lock-service-3g-to-connect-to-the-visionline-server)
3. [Download door lock data from the Visionline server to Lock Service 3G.](#download-door-lock-data-to-lock-service-3g)
4. [Initialize each door lock to program it with the correct settings.](#initialize-door-locks)
