CDVI KTAG key fobs are low-frequency (125 kHz) tags based on EM4100 technology. The key fobs do not have the full serial number printed on them, therefore, CDVI KTAG key fobs can only be copied by renting our cloner or mailing your key fob in.

We now partner with the RFID duplicator leader Tiny Labs to make the duplication even easier, you can also purchase a Keysy device to duplicate the tag yourself, please check the instruction video below:

We support the following duplication methods for CDVI tags:

• We ship you a Keysy RFID Duplicator along with blank key fob(s). A deposit is required. A return shipping label is included with your purchase for USA customers. Canadian customers need to pay for the return shipping themselves.
• Mail your key fob to Mr. Key Fob. Please contact us first, we will provide the shipping address for you to send your key fob in. Please place an order after you ship your original key fob to us with the tracking number so that we know which package we receive belongs to which customer.
