Ok, I finally got around to trying this out.

i successfully added a fourth key to my 2004 - with a few minor bumps along the way.

- I bought a 35113-S9A-A01 key from Honda Automotive Parts, it cost $30.62 + shipping.
- My local Ace Hardware cut it for $10.

I found the first iPadOS session with the AP200 to be frustrating. A confusing setup process, but as a software engineer, I am a bit critical...
The biggest surprise was that the app will download a second, country of manufacture app.

The menu tree needed to get to the key panel is :

Service-->Immo keys-->Honda-->USA-->System Selection-->Hot Functions-->Special Functions

The bump along the way of adding a key was that the AP200 will ask for the number of original keys (3 in my case) and how many to add.

It needs ALL of the original keys that you have. I did not expect that and ended up erasing all the keys except for the one I was using.

After getting my original keys, I re-ran the process but said that I had one original key and was adding three.

You need to start the session with a functioning key and are then instructed to remove that key and then follow prompts to use each additional key to turn the ignition On and Off within a specified time limit.

So, $125 total I have a new key and an AP200.

 

I was able to get a new key have it programed by Ace Hardware. They charged $89 US for the key and programming service. It was a bit a challenge for them, but they were able to do it. They had to copy the key by hand since the automated key copy machine would not allow them to make a copy of the key. Once they copied the key by hand, they used a tablet and connected to the ODB port in the car to program the new key to the car. It works and it is much less expensive route than having it done at the dealership!

It was important to relay that it is a chipped key. They could not detect that with their automated key copying machine.

I initially tried Lowes Hardware. They could not make a copy.

 

Me if you still have them.

 

Still have them but new users can't receive/send messages. Post a # and I will txt you.

 

'the keys are just sitting here. Will wait in until one of us can message the other.

 

I'm confused now? I thought the Autel works good? Or, is it cuz a specific model Autel for specific MY S2k?

 

It worked and I am happy. I was skeptical at first and worried that I had wasted money on the Autel. See my later comment.

 

Ah, I see. Cool.

Please post specifics too - what model Autel (100 or 200?) and also MY S2k.
