ASSA Code Handle /Local/EE/Images/Codehandle_524x224.jpg Now you don’t have to bother with keys to your patio doors and window locks. Our Code Handle security handle opens and locks with a code – easier and extra secure! Existing security handles are often at risk because people leave the key in the lock or on the windowsill. And for those who don’t do that, it’s often a hassle to find the key when you want to lock or unlock the window or door. The Code Handle eliminates these problems. The lock mechanism is maneuvered with a built-in keypad. Press a 6-digit code to unlock; a green light blinks for each press of a key. To lock, press the button with the padlock symbol and a red lamp lights. The code is easy to change whenever you like. The lock can remain in the current position, locked or unlocked, for an unlimited time without affecting the lifespan of the batteries. The two batteries have power to lock and unlock the handle about 100,000 times. The handles come in both right and left-hung varieties in shiny or matte chrome. Easy to install with two accompanying security screws. The handles meet the mechanical requirements of the SS 3620 class B standard, which is what insurance companies require for locking patio doors. You can find the Code Handle at locksmiths and select home improvement stores.
