The installation of the Console Vault with four digit combination lock was easy to install. The instructions were easy to follow, but did not mention that once you get vault into place and fastened correctly you replace the trim piece that you removed in step one. It takes a little maneuvering, but everything fits just fine. One thing I wish Console Vault would explore, is a sectioned tray that would fit in the bottom of the vault to help organize the items that are placed inside. All in all, the vault is well made and very sturdy. I highly recommend it.
