Electronic Keyless Digital Door Locks with Numerical Codes
Electronic keyless digital door locks with numerical codes are more advanced than regular maglocks. These devices must be opened using a security code which must be entered by the user. These locks are usually built with a keypad which is used to enter the password. They are frequently found in apartments and can usually be used to easily replace standard doorknobs.
