How do you manage your keys list?

I dont

A spreadsheet, several tabs, some highlights when they are "used" in a GA, and remove entirely a week after they are marked as received. Listed where I want to give them away.

I also have a calculated field to tell me how many times I have GA'd each game on SG (to inform me when I'm hitting the 5 per game threshold), and I have a status for running GAs, but otherwise that pretty much covers my one tab (minus the Steam stuff - that's all in another set of tabs to keep track of my collection, wishlist, etc.).

Name | Steam link | Key/Gift link | Price | Source
Link is colour coded for games under 65% ratings, price is colour-coded for bundle and non-bundle according to site rules.
Used keys are moved to a different tab immediately so the available list doesn't get cluttered.

I just use IsThereAnyDeal but I don't trade.

I do everything with flat files, usually comma separated.

Also a spreadsheet user here. OpenOffice Calc in my case, I go pretty basic and just do Title-Source-Key-Status-Notes.

As an alternative, you may want to consider using a database like MS Access or MySQL. It would take a bit longer to get set up, but much better at things like search/sort/filter and more customizable. I currently have a WIP database solution for my games collection/wishlist and might add something in there for key management down the line, though I haven't had a huge need to organize my keys beyond what a spreadsheet can handle fairly readily.

I don't have too many keys. At the moment they are saved in my E-Mail account within the original bundle page. Since I only generate keys for games I either activate on my account of for a giveaway I can see easily which ones are used and which are not used. But like I said I have only 5 bundles bought plus minus one.

Personally, I gave up

ACE - Arena: Cyber Evolution - ACE Founder Pack DLC
H990K-V9LYK-LPFYD

Glow Ball - The billiard puzzle game
Z8HFG-XDJFD-087BN

Ionball 2: Ionstorm
DA3YZ-5P6MI-ZAZGE

Pahelika: Revelations HD
J9KAK-FN6KI-PJT9G

Siege Wars

:D

Google docs spreadsheet:
Website | PackName | GameName | AppID (currently not filled in for any game) | Key/Link | Satus (blank for available, trading, unsure) | Notes (used for trade links)

Spreadsheet with game name, full price, key, where i got it, date i got it, and any additional notes (like where/who i gave it to)

I keep on notepad =)

Haha... I don't XD
I think I tried to do a database in access(heck, I think I even finished it) but never actually used it. When I need to find a key it takes me several minutes T_T , I'm that disorganized with my stuff.

ArchiBoT database.

I'm unique yet again.

Here's my excel's fields:

Game Name, Keys, Status (Used/Unused), Type, From, Notes, Date Traded, Trader

Spreadsheet (Open office Calc)

Games for trade
Games I may want but may trade if I find something better (thus not on my "have" list in the trade forum)
Games I want but won't redeem until I've played more of my current library
Delete anything once redeemed by me or others.

Most of my gibs so far have been gifts so no category for it on my spreadsheet yet. All current keys due for giveaways are simply on the bundle website I got them from.

I get rid of leftover keys before the list gets too long....

Easy. For every new Steam key I acquire, I immediately try to redeem it on Steam. If it tells me I already own the game, I create a giveaway here, minimum duration, open to all. No need to complicate things. (I wasn't always this efficient, and it was a pain in the posterior.)

I don't have a keys list.

On Excel, these fields: Sites - Bundles - Games - Keys :)

Since you covered most of it I use Color Backgrounds on Excel Cells to see at a glance for activated, keep, given.

Also for others reference there's an app which might be useful: http://steamcommunity.com/groups/gkeybank

Google Docs

Just two columns, game name and key.
Three sheets - the main one is unused keys of course
second sheet is for keys for my currently running GAs, when all are marked as received they go to the
third sheet, which is keys I've given away. Don't know why I keep this one. Maybe just to stroke my ego at the number of rows in there?

I keep them all in an Evernote note. 4 columns: game, key, where I got it from, status (used, ongoing ga, ...) Think I might start colour coding them based on everyone else's systems.
