My son who was an avid bit-coiner just passed away suddenly (couple of weeks ago), he has mentioned in earlier conversations that he has a "large" amount of BTC in several encrypted wallets. He was using Ledger and Razor - I found the keys and recovery sheets among his belongings, but not a password. Is there a way that the Ledger and/or Razor sites may be approached to access his account since I do have most of the info for the account? Any help or guidance will be appreciated.
Sorry for your loss. 
Ledger wallet are special wallet especially made for storing Bitcoin. I'm afraid those site owner can't help you with passwords. You must have password to gain access the Bitcoins stored in wallet.
Can you tell more about it.. Did you try opening Ledger wallet on Laptop? What did it asked? You need either PIN number or 24 words secret password to unlock the wallet.
