How to Lock a Door from Both Sides: Secure Locking Solutions Explained
Published Date: Aug 20, 2025
Looking to add more privacy or control to a room in your home? Whether it's for a bedroom, office, closet, or unique door style like a barn or pocket door, the question of how to lock a door from both sides is more common than you might think. Sometimes standard locks don’t cut it — or aren’t there at all. This guide breaks down your best options and practical alternatives to help you secure your space the way you need.
Understanding Your Options for Locking a Door from Both Sides
Not all interior doors come with locks, and even when they do, they might only work from one side. If you're looking to lock a door from both the inside and outside — whether for privacy, security, or access control — there are a few ways to go:
- Double-cylinder deadbolts: These locks use a key on both sides, offering controlled access in either direction. They’re best for doors where safety outweighs quick exits, like storage areas.
- Privacy locks with exterior access: These often have a button or thumb turn inside, and a small hole outside for emergency access using a pin or flat tool.
- Electronic or smart locks: These allow you to lock or unlock from both sides via code, app, or fob. Many models work with interior doors and can be a sleek upgrade.
In cases where a permanent lock isn’t possible or necessary, you might consider surface bolts or latch-style hardware that can be locked and unlocked from either side. If you’re not sure what suits your space, a home locksmith can assess your needs and help you choose the right setup.
How to Lock a Sliding Barn Door from Both Sides
Figuring out how to lock a barn door from both sides takes a bit of creativity, since these doors don’t sit flush with the frame. Still, there are several hardware options available:
- Hook-and-eye latches (double-sided): With careful placement, you can install these to allow locking from both sides.
- Barrel bolts: Mounted on the door surface, these can slide into an anchored piece on the wall. Some versions have exterior key access.
- Sliding latch kits: These are designed specifically for barn doors and often include dual-sided locking mechanisms.
If you need a simple fix or are renting and can’t drill holes, temporary solutions like a wedge or floor stopper can provide light-duty locking when you're on one side of the door. Just remember, these won’t lock from both sides unless mirrored on each side — and they’re easy to bypass.
How to Lock a Pocket Door from Both Sides
Pocket doors are another challenge since they slide into the wall and leave no space for standard locks. Wondering how to lock a pocket door from both sides? Here’s what works:
- Recessed privacy locks: These are specially made for pocket doors and allow locking from the inside with a turn or button and unlocking from the outside with a coin or flathead tool.
- Keyed pocket door locks: For stronger security, some models allow key access on both sides — ideal for offices or closets where privacy is key.
- Magnetic or adhesive locks: While not heavy-duty, they’re great for closets or light-use doors when drilling isn’t an option.
