Accessibility of Key-Operated Locks

I haven't found anything in the accessibility standards that addresses keys, or locks operated by keys, and I've heard that this is because the key is not a permanent part of the door/hardware and is therefore not covered. But if a lock requires a key for operation, it seems like it would be difficult for someone with a disability to operate it. I've seen deadbolts that use a keypad instead of a key, but you have to turn a turn-piece to retract the bolt. This may be easier for someone to operate than inserting and turning a key, but the turn-piece may not be considered accessible depending on who is evaluating it.

I would appreciate your thoughts on this. Is it ok to install a key-operated lock knowing that it may be impossible for some users to operate but is not officially addressed by the ADA, or would it be better to install a keypad-operated lock with a turn-piece that is easier to operate than a keyed deadbolt but may not be operable by anyone. Is there anything in writing about the ADA's stance on keys?
 
Is this for residential or commercial?

My initial thought, if commercial is:

1008.1.9.1 Hardware. Door handles, pulls, latches, locks and other operating devices on doors required to be accessible by Chapter 11 shall not require tight grasping, tight pinching or twisting of the wrist to operate.

--AND--

1008.1.9.3 Locks and latches. Locks and latches shall be permitted to prevent operation of doors where any of the following exists: (I didn't list all the exceptions, but one requires a sign stating the door is unlocked when space is occupied)

I'd say a key would require tight pinching? JMO

Other than that, I am not sure it would be applicable in a private setting because if the owner is the person needing the key to get out, they would have the option to buy/install something else (I am thinking mostly residential here).
 
Sorry, my reference was IBC and you asked for ADA

4.13.9* Door Hardware. Handles, pulls, latches, locks, and other operating devices on accessible doors shall have a shape that is easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting of the wrist to operate. Lever-operated mechanisms, push-type mechanisms, and U-shaped handles are acceptable designs. When sliding doors are fully open, operating hardware shall be exposed and usable from both sides. Hardware required for accessible door passage shall be mounted no higher than 48 in (1220 mm) above finished floor.

Similar language

It is not an issue, unless you have a disabled employee. It becomes a reasonable accommodation issue . The public does not have or need keys.

If you have a disabled employee you will need to install a keypad

And if they cannot work a keypad?
 
My question was general, but key-operated locks are prevalent in both commercial and residential (multi-family) applications.

In a commercial application, the public does not typically use the key - the door is unlocked before they enter the building. But think about a restroom that requires a key to retract the latch. Does the ADA prohibit that type of lock with the no-pinching/twisting language, or are keys not addressed by the ADA so the lock is acceptable?

In a multi-family application, an apartment resident either uses their key or some other method to enter their apartment. An accessible unit has to meet the no-pinching/twisting requirements, but what is the accessible alternative to a key-operated deadbolt? I have not seen any code officials reject the use of key-operated locks (except when the key is on the egress side).

So is it just an urban myth that the ADA doesn't address keys?
Yes the ADASAD does not address keys

404.2.7 Access gates in barrier walls and fences protecting pools, spas, and hot tubs shall be permitted to have operable parts of the release of latch on self-latching devices at 54 inches (1370 mm) maximum above the finish floor or ground provided the self-latching devices are not also self-locking devices and operated by means of a key, electronic opener, or integral combination lock.

ADASAD Advisory 404.2.7 Door and Gate Hardware. Door hardware that can be operated with a closed fist or a loose grip accommodates the greatest range of users. Hardware that requires simultaneous hand and finger movements require greater dexterity and coordination, and is not recommended.
