My mom, 94, has recently progressed from banging at the entrance door to the apartment calling "mother, mother" to going downstairs at 2:30 in the morning, knocking on the superintendent's door and wandering around the lobby in her nightdress. Thankfully, the superintendent brought her safely up. As it turned out, the locksmith was in the building the next day to change the locks on the entrance doors in the lobby, and I spoke with him. He gave me three options: door guardian, barrel bolt with padlock and double cylinder deadlock. Since mom would be able to reach the door guardian despite her short stature, I am afraid she'll soon figure out how it works, even though it is childproof.
The barrel bolt with padlock would require a key. My two concerns are not that mom will get upset/angry at the sight of the padlock. Also, I am in and out six times a day, and sometimes she gets angry and locks me out by putting on the chain. The other concern is accessing the key in an emergency.
The third option was a double cylinder deadlock, again requiring a key that opens from the inside and outside. My concern again, is having to get out in case of emergency (although the superintendent would also have a key) , and the frequency of my coming and going.
Are there other options that the locksmith has not mentioned? What has your experience been with child/senior proof locks?
