It's not easy to keep track of the tenants when there are a hundred apartments in the same block. It is ideal to hand over the key to the tenant with key tags. The Homesmiths key tags are plastic key tags that come with write-on inserts that are attached to the metal key holders. These key tags are especially great to use with Security Key Cabinets. They are of great help for storage facilities, fleet truck companies, offices and rental management companies. And if you have got a key with information written on it, it's always easier to find it when it's lost.
