Until the remote fails and the lift is halfway between ground and the van. Not electrical ground but the sidewalk, driveway or parking lot.

Suddenly you find yourself with a 300 pound client in the air and no easy way to get them off the lift. It happens.
And in this situation, if I had replaced the remote, I guarantee there would have been at least one lawsuit.

But what do they say for when the lift is stuck? Or when the interlocks fail and the lift descends in a rapid uncontrolled descent?
They don't go into details, and I do not know anything of the NHTSA regs, but I am assuming that if the vehicle lost power or similar instance there would be built in auto slow descent.
Some are hydraulic, or hydraulic assist, it should be possible to build in auto safety features in the event of power loss etc.
I cannot see any there being an alternative as this would raise all kinds of safety concerns.
Hence the regulating body.

Well, at least in one case I can confirm that In some situations, there is not a slow auto descent. It happened to me. I’m not telling any story.

Well the events that may occur in the event of a malfunction I have no knowledge of, never having any experience with said lifts. Which may indicate that replacement of any remote may not require any great concern as to fail safe etc!
I would have expected some kind of emergency override procedure.

I have no knowledge of your experiences, I respect you have obviously more exposure to the issue than me.
I am just voicing what I would have expected, having worked with industrial equipment and the multitude of safety precautions that are in place, I assumed, rightly or wrongly, the same would apply.;)

Sure! That appears to be a reasonable assumption. But it’s wrong and that’s what I was trying to illustrate.

No worries! It’s all good.,,

At this point it is not known if it is as Post#9.

Max, it is wireless. It has a range of at least 50 feet which is the most I have used it at. Max range I do not kno

To address the concerns about failure of the equipment in question. This unit would just stop if the remote failed and there are manual over rides in this case. The thing that is important is that there is another person with you to operate the lift if it failed. It will not drop unless something mechanical broke, which there is no control over fate.
No worries! It’s all good.,,

I am still jumping through hoops to see if there is a replacement remote available. If I figure out how to upload attachments to this site I will put pictures of inside and outside of this remote.

The "Upload a File" button below the edit box allows it.

When you start to type in a reply, at the bottom of the reply box there are 4 other "buttons" - "post reply" - "upload file" - "my attachments" - "more options". If you click on the "up load file" you then browse in your computer and open the file you want to up load to the site.

You can also drag and drop photos from your drive into the post's text entry box. They'll be automatically uploaded. Be patient, it may take a minute especially if you upload several at once. I've also had success using copy and paste to place photos into a post but it isn't 100%.

How many functions does the remote have?
Apart from the expected UP/DWN ?

There is such a thing as a learning remote. If the old remote is still working a bit, you may be able to train the new, learning remote to execute the same codes as the old remote. That's if the old remote uses 'standard' signals. It could be purposefully built to use non-standard communication, just to enforce that you buy remotes only from the supplier.

I hope these files will help. It has six functions. The yellow wire is where I jumped it. It appeared that the battery was so hard to be removed that the trace was broken and soldered a couple of times before so I installed the wire.

From my experience with those kind of button contacts, that maybe where the problem lies, it may be possible to rehouse the board and use/install/wire in a different style of P.B. if this appears to be the problem.

I agree with Max. It is probably the conductive surface on the rubber buttons that short the conductive tracks on the PCB when they are pressed. This is a common problem with TV remotes. Try and see if it works shorting the black conductive tracks with a small piece of metal fixed to the end of a piece of insulating material. (If the metal is in contact with your fingers it may not work.) If it works that way then there are some conductive varnishes available that can be painted on the underside of the buttons to repair the conductive part. If you search for "remote control repair kit" on ebay you will find some possible solutions. This is a product that I have used. It works but has to be re applied after a few months.

I hate that kind of button. My Yamaha receiver has a very expensive (to replace) remote that is nearly useless because of those buttons. I've cleaned it extensively but some buttons work and some don't.
