My iMac does not have a memory module door release button above the ac power cord jack. There is a small horizontal open slot below the power cord jack. Should I use a plastic spudger to release the cover or will I wreck it ?
The late 2013 iMac does NOT have user upgradeable memory. That is why there is no memory module door.
Only the 27" iMac has user upgradable ram. Did you remove the power cord? https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2639+RAM+Replacement/20249
Sorry I must have been looking at something else.
Mike post a link to the iMac 27" RAM replacement instructions.
Here is the link to the 21.5" RAM replacement instructions (not for the inexperienced) -> https://www.ifixit.com/Guide/iMac+Intel+21.5-Inch+EMC+2638+RAM+Replacement/28795

Is your iMac a 21.5" or 27" model? If it is a 21.5" model RAM is not upgradable.
The RAM in the 21.5" is upgradeable but not "user upgradeable" as defined by Apple.
Some further info regarding the 21.5" Late 2013 iMac from EveryMac.com…
*By default, this system has 8 GB of 1600 MHz DDR3 SDRAM. Apple does not intend for one to upgrade the RAM in this system. However, as first reported by site sponsor OWC, this system has two SO-DIMM slots (204-pin). Unfortunately, accessing these slots requires one to pry off the display that is glued to the case and remove the logic board.
I'm sorry. I should have said my iMac is a 27" model from late 2013.
It does have a memory module access door but no release button over the power cable jack.
If the memory upgrade page is accessed, you will see that the late 2013, 27" model has no reference saying one way or the other whether it can be upgraded or not.
Do you know what the horizontal slot below the power cord jack is for ? I thought it might be the unlock to allow the door to be opened but perhaps it is a test cord jack.
Mike, do you know what the horizontal slot below the power cord jack is for ?
P.S. I tried removing the power cord but the door did not open. 😮
Did you take a look at the page referenced by Mike? It clearly shows a button above the power cord that you push and the RAM door opens.
Unfortunately a button on a page does not help me. My 27", late 2013 iMac has no such button.
Go to "About this Mac" and post what it says after iMac. If you don't have that button you probably don't have a late 2013 27"iMac.

According to Apple, when I access the service and support page, my iMac is a late 2013 model per my serial number.

There is confusion here. The link that Mike posted above shows clearly how to upgrade the RAM in a 27" late 2013 iMac. That is why I am asking you to check and post the information from "About this Mac" .
