I can't specifically talk about Lowes, but my GEMB JcPenney card stayed opened for 10 years without me using it. I noticed recently that it was still updating every month on my CRs so I went out and was able to use it without trouble. Now, this account wasn't doing my scores any good since it was inactive so long which was my reason for awakening it from its slumber. I suspect what will govern it closing is how Lowes set up their accounts with GEMB.
Changingmantra,
If you don't use a card within a 6 month period then the card is treated the same as a closed card by the scoring model. I read that in an interview with someone who worked for FICO. Many people here advocate using your cards at least once every 4 months. The good news is you only need 1 store/gas card to report as active to be of use in your scoring.
Even if they are actually reporting on Equifax? I just reordered Equifax 
Looks like I have to start all over AGAIN. Score is now 569 after 4 medical collections in one day! Dumb *&*Y*( billed the wrong insurance company! And I have high utilization, nothing but time will fix that.
Ok, so I have these 3 GE/M accounts, which I have never used. They are reporting on Equifax... so does that mean they are being calculating in my score even though I have not used them? Firestone, is reporting as 0 balance 0 CL, even though I have a 1200.00 CL with them but that is a whole other mess I wrote about earlier.
