Just a bad product unable to write blk 0 manually or during a clone always fails, if you force it it bricks. Do not buy this trash waste of money. Get a S50 + T5577 Combo Key Fob | HF 13.56MHz + LF 125KHz from mtools tec.

The blue ones are circular not rectangular as advertised. These are not writable as described

I use Flipper ZERO to write keys, and if the key is branded, then you can only write the information that a specialized device for this type of key adds. Accordingly, these keys are not for everyone, and I consider them unsuitable! Buy the one in my picture, blue, it works without problems with all devices!

This may be dual frequency but it's not the two frequencies listed in the description. I was able to write the 13.56 to it but not 125Khz so they were no better for me than single frequency but clunkier.

They work but they don't seem as reliable as others we have and are kind clinky, meaning the plastic they are made from makes a lot of noise hitting against my keys

They don’t work! Emailed support and they were not any help.
