I tried my US atm card in Banamex, and a few other banks and could not get any $. I tried Bank Norte on the corner of Juarez and the highway and at that time they would allow withdrawals with non chip cards. I know the problem was chip vs non chip because my bank knows I live here and I know what I have for funds. Also, I was with a Mexican who had atm cards with chips and he had no problem getting cash out of the same machines that denied me cash.
I don't think this is accurate information.
Nor is the 'you need a 4 digit PIN'. Longer PINs will work in Mexican ATMs too.
