The keys

There are no basic, if you mean cheap, campgrounds in the Keys. This is off season right now so at least they won't be charging winter rates. We like Pirates Cove on Marathon.

Where in the keys do you want to be ? It's a little over 100 miles from Key largo to Key West and there are many CG's along the way.

Point of view key largo

And most of the islands are only wide enough to support the road and Henry Flagler's railroad tracks. The keys are a string of coral atolls 100 miles long from Key Largo to Key West. That means 100 miles south and 100 miles north on the other side of the road. Some of the larger islands have CGs and some have imported sand to build a beach. Otherwise, bring shoes or you'll cut your bare feet to ribbons on the coral.
As you can tell, I considered the drive several hours of my life that I'll never get back.

The 4 state parks offer basic camping at the best rates in the keys.

Marathon is a good area to camp. Around 52 miles to key west and around 50 miles to key largo. Jolly Roger is a good cg. There are around 6 or so cgs around marathon.

Jolly Roger worked out well for us a couple of years ago - also got the P.A. rate which was a bonus. The pool is great and the waterfront area is very nice. We hope to go back again.

But you can't get waterfront sites with the PA...

State parks will run you about $38/night for water and electric. If you go somewhere like Jolly Roger and use PA, you might pay around $40-50 (depenfding on how many people you have). Go to somewhere like BlueKey and you will pay $100 or more per night. Although they are real nice sites. But more than basic.

A couple of years ago we stayed in Marathon at Knight's Key RV Resort. Basic campground with a nice tiki bar to watch sunsets. It's at Mile Marker 47. Reasonably priced. No sewer, but they will pump you out at your site. We like to walk in the mornings and you're right at the 7 Mile Bridge with the old bridge to walk/bike on for several miles. There are others in this area. Jolly Roger appears to be favored by many.
