Utilizing a bike or fridge lock is also an excellent option if you have kids. You can set a combination that your kids don’t know so they can’t open the door to leave. However, this French door lock is only feasible with certain door handles. 

If you have a twist handle on the interior of your French doors, you will find attaching the lock difficult. For turn handles, you will need to wrap the bike lock around the handles numerous times until you achieve tension.

Rulart Double Keyed Deadbolt Lock

Rulart Double Keyed Deadbolt Lock

One of the main security concerns of French doors is the glass that makes up the doors. If someone wants to enter your home, they can bypass your French door lock by breaking the glass and removing it. 

The best solution we have found to securing French doors from this weakness is a double-cylinder deadbolt. A double-cylinder deadbolt requires a key to open and close the lock on the French door. 

While this will enhance the security of your French doors, it comes with a fire safety risk. Most fire departments don’t recommend a double-cylinder deadbolt because it impedes your ability to escape unrestricted from a property.

Frequently Asked Questions

Do French Doors Need Special Locks?
