Converting a double cylinder gate latch to single cylinder?

Hi all, the security gate to my complex is a double cylinder, as in requiring a key to enter and to exit (similar to these). Not only is that illegal and dangerous, but also quite inconvenient.

I'm assisting the HOA with the complex. If we were to convert it to single cylinder (knob on the inside), can we purchase the knob and switch it out? Or is it not worth the trouble/cost and better off buying a single cylinder set? Thanks!

We can't see the gate, but if you can reach your hand through it, whats the point in having just a knob on the inside?

You might have to replace the entire handle set with one that when locked with the key, can be opened from the inside, but is still locked when it closes. The problem might be that if someone unlocks with a key for access, they may forget to relock it after opening.

I'm sure there are specialized locks that would meet your requirements. Our Pro's will be around....

As mentioned, you can install a storeroom door lock that is key operated outside (always locked) and always unlocked inside. You need to shroud the inside handle so it cannot be accessed from outside.

If the gate is steel, this is easily accomplished by welding a large plate to the door.

What you have there is essentially the same thing but with key inside. You cannot use the inner thumbturn from another product because the tailpiece will be too short (on the external cylinder)

At the condo where I used to live, we had 5 pedestrian gates into the common area...we used expanded metal to cover the gates, and used Grade 2 "storeroom function" cylindrical locks with knobs, not levers. (there were only 20 apartments so the locks did not get very heavy use. If you anticipate a lot of traffic, get Grade 1).

Perhaps a simple and inexpensive solution may be to use a standard entrance set that can be used like a storeroom lock and fit one of those child protective plastic spinners over the inside knob. While not a perfect solution, it might help to make operating the inside knob more difficult from outside.

A quick note about knobs vs. levers: In the USA, the ADA (Americans with Disabilities Act) mandates that on "public use" doors with existing "knob" latches or locks, when repair or replacement is necessary, OR if a handicapped person requests it, a lever type latch/lock be installed as a replacement.

A HOA, whether of a condo or group of detached homes, is not exactly "public use" so the law doesn't technically apply here, but, especially in a really large complex, where there's a likelihood of having a few handicapped owners who might be adversely affected by the proposed changes, it's advisable to get their input to get the best balance between accessibility and security.

that is not entirely accurate rstripe. the rules read "locks than can operate with a clenched fist".

Yes, lever locks do this, but so do locks that operate with a press button or push/pull paddle.

Yes global, I'm aware of the range of acceptable lock handles under ADA, but the type of handle is determined by the door prep....in OP's case, (per his photo example anyway) the popular ANSI 160/161 prep would call for a cylindrical lever lock as replacement. Push buttons and paddles are acceptable, but, with very few exceptions, they do not easily adapt to this door prep.

perhaps you need to look a little deeper into products and availability. There are really excellent quality products designed to fit this door prep, that are competitively priced, simple to operate, easy to install and good looking. Rules here prevent handing websites for those products. If interested PM me.
