It's not for me. I have thick plastic coated Toyota keys and a door locking device. This unit does not manage these keys well at all. One either has to create a very wide holder with spacers on the opposite side or one has to pay for additional accessories to have the keys hang off the end of the unit, so the key holder begins to look and act like yet another key chain ornament. If you use standard, thin, uncoated keys, like a janitor with 10 keys, this might be for you, but non-standard keys on this is not worthwhile.
