So step by step:
1. Crack wep key.
2. take key convert to ascii
3. insert key in wireless connection app or commands.
4. Save key either on disk, paper, head or other place.
5. Re-use key next time key is needed.

oh so you want to run airodump-ng to collect iv's then save them and start again the next day and add them together?
so as an example

airmon-ng --bssid 11:22:33:44:55:66 -w day1 --output-format pcap mon0

then

airmon-ng --bssid 11:22:33:44:55:66 -w day2 --output-format pcap mon0

and then just

cat day1 day2  > combo

where combo is the combination of both days iv's
with linux you can merge files quite easily with cat

this will save all files in root
you may have to change it up if you are using a usb but it's still possible, i don't mess with wep its too overdone, but if you are close enough to the ap, and there's traffic on it there's no reason not to have 10,000 ivs in 10 minutes or less and most 64 bit weps can be cracked at 5000 ivs especially with ptw and 10k to 20k for 128 bit. experiment with the options for aireplay-ng
