Sure, if the tag doesn't have the password mode set it should not be a problem.
Then you would need to know the password...

Re: Rewriting t5577 cards
I'm new to proxmark and I tun into same issue/question.
How to rewrite T5577 ?
I used t5577 card to clone an Indala card and it worked just fine then I tried to clone an Awid key (which wasn't successful yet).
So now I'm not able to clone Indala card into same t5577 card, proxmark client just says "No Known Tags Found!" after I trying to clone indala card.
Any ideas ? How to reset t5577 card ?
Thank you for advice.

Re: Rewriting t5577 cards
All right so here's what I did, I wrote All blocks 0 ... then tried to copy indala card and again i'm getting "No Known Tags Found!"
This t5577 was working fine yesterday.
I'm I doing something wrong ?

He said write a correct block 0, not all other blocks to 0
