Great modern key solution
I use this to store keys for the clients in the van. Its very sturdy and feels rigid providing good protection for the keys within. Touchpad is easy to use and the voice prompts are helpful. The box connects to your phone and is easy to unlock, however the fobs are very small. Its also quite heavy so might not be suitable for all walls or doors. Very expensive however. Attached is a photo of the keys I store as an example of the size suitable.
