Conclusion

There are many different types of locks that can be used on french doors, but the most common and effective type is the deadbolt lock. This type of lock is very strong and difficult to break, making it an ideal choice for security.

Deadbolt locks can be either single or double, and most french doors will have at least one of each. The double deadbolt lock is the most secure, and is often used in combination with another type of lock, such as a keyed lock.
