YARONGTECH ISO 14443A 13.56MHZ RFID 1K Keychain Blue color pack of 10 (Blue-ID Printed)

I really did not expect much and, was unsure if these would work on my door locks but, for this price, I took a chance and ordered them. I'm glad I did. I simply put in the code to add user, touched each of the IC chip to the door and they were immediately recognized, and programed. Now my family has access to my house without remembering the code.

Honestly, not sure if it was our air or listing here the frequency supposedly matched however, these did not work on our electronic locks. Return was easy.

I just purchased these key fobs and they are not working. Where can I get customer service to help me figure this out?

These fobs work with my KeyInData 6500 series locks, five stars. I purchased the fobs with the ID# engraved on the shell. The ID's do not match what is programmed into the RFID chip. For this, minus two stars for the hassle of having to determine the correct ID#.

These key fobs work great with the EMKA Agent E Electronic Swinghandle. I am glad these are individually printed on, clearly, and are lighter than the standard key fobs we have to get into our building. Very useful for our employees who are running around the building all the time.

Ok

I purchased in June 2022. I'm able to get a HEX8 code from the card (for example 124AED1B) which seems appropriate, however, the decimal code 0468535826 printed on the back does not match this in any way. I've tried reversing binary digits and a few other conversions, but it does not appear the code on the back corresponds in any way to the chip UID. The fobs are good quality and each one has a unique code, however, the mismatching codes on the back make it useless for my project.

Easy to write, and perfect to take and put anywhere.

Cumple con las especificaciones pero me gustaría un mejor precio
