I found Clone My Key doing a Google search seeking a trusted company who could reliably copy our encrypted office (HID Poly) key cards, onto key fobs.
I decided to contact two companies, and after reading the reviews on YELP! decided to go with Clone My Key. It's been a great experience! I emailed them asking a ton of questions, and sent them a photo of our HID cards to ensure they could help. They promptly replied with confidence and answered all of my questions.
The next day, I mailed them my card and about 4 days later had all of my key fobs as requested. I went with black, without logos. These are GREAT!
Every single one works like a charm. The range seems as good, if not better than our cards', and they are SO MUCH better than the chunky and enormous cards we were issued for our office building.
I highly recommend Clone My Keys, and plan to recommend them to all of our office tenants!
