For years Tidel has made a great electronic safe that vends money. Over the years some of these safes have become obsoleted and very difficult to maintain. We are running into some challenges with the tacc IIR. If you need parts or service please feel free to contact us. www.esilock.com We can guide you as needed. Another place to look for parts would be ebay or perhaps craigslist. Keep in mind these parts are NLA from tidel, so you are basically looking for wrecking yard style parts.
