Vault Lock Adapter Kit

Being locked out of your garage is undeniably frustrating, whether caused by a power outage or simply forgetting your transmitter. Fortunately, the Marantec Vault Lock kit provides a practical solution. This kit, when paired with a standard vault lock (readily available at most hardware stores) and the included adaptor, enables the addition of a keyed entry to your main garage door. With this setup, you can release your garage door from the outside, ensuring you're never left stranded.
To unlock the door, simply insert the key, turn it to unlock, and pull the vault lock handle back until you feel a gentle pop in the cable. This pop indicates that the door is unlocked and ready to be raised manually.
