My Jeld-Wen patio doors (french doors) have single cylinder locks. Burglars used these doors to break in this past weekend. They simply broke the glass and reached in and unlocked the door. Fortunately, I have an alarm system.
I contacted Jeld-Wen and they do not offer a double cylinder key option. (They reminded me this was a fire hazard and I reminded them that home invasion is also a hazard.) Jeld-Wen simply had no options for me other than to "call a locksmith."
Does anyone know how to add a double cylinder lock to these doors? Please see the attached photos.
