Progress the main quest until you can return with the required lockpicks
Buy lockpicks from a merchant if one is available
Pickpocket lockpicks from a guard or trader
Check nearby chests, sacks, and containers for spare lockpicks
Complete a side quest or activity that rewards lockpicks
Reload an earlier save before reaching the point where you need them
Use a different character or companion if the game allows it
Return later after obtaining lockpicks through crafting, trading, or looting
Look for an alternate route or key if the door or container has one
Avoid forcing the lock if the game offers no other option until you have lockpicks
