How to Open Valve for Sprinkler System

I'm trying to turn on the main valve for my sprinkler system. It's in a valve box near the sidewalk. I usually have my sprinkler company do the opening every year, but they are so late getting out. I have a hose bib that's connected to the system, which I use a lot when it gets warmer. I expected it to be the usual type (with the long valve key), but it's not that style. It has a yellow Rainbird cap on it. I'm not sure if it's some type of quick coupling valve. Can anyone tell me what I would use to open this? Is it something that I can get at Lowes/Home Depot, or would I likely have to order this online? Thank you!

Here is a picture (it's not a very good one, unfortunately):

I feel so stupid. I think that is actually a quick coupler and not the main shutoff.
I'm going to take another look as soon as I get home.

Looks like some kind of shaft in the middle.
That could be an underground water shut off.

A water main from the street would have a valve like that.
Typically a sprinkler system would not be controlled with a valve like that.

This is a picture zoomed out. When I've seen them open it in the past, I usually see them with one of those long valve keys. Is it possible that it's down that PVC pipe? I don't see any other boxes for the sprinkler, but I know the main is somewhere in this area.

That looks the key location for the water main.
Where is your water meter ?
The sprinkler system must be connected after or on the house side of the water meter.
There would also need to be an anti-siphon valve... like in the picture... near the shutoff valve.

The water main is right below the sprinkler box and is closest to the street. The anti-syphon valve is on the side of my house. When I've had my sprinkler opened in the past, I've seen them near the street turning on the water. I assume it's in this green sprinkler box, as I see nothing else in the area. The previous picture that I posted is the inside of that box. I believe the valve with the yellow cap is a Rainbird quick coupling valve. All I can think of is that the PVC pipe leads to the shutoff for the sprinkler? It appears to go down about 30-36".

Look into Yo-Link motorized water valves that can be controlled with a smart phone and app from anywhere. Perfect for irrigation systems, etc. I just had two 2" stainless-steel motorized ball valves installed recently for a loop irrigation system fed by two 2" city water meters.
