The only lock alternative for this model is with a key lock,
Securikey Mini Vault Deposit 2K. Due to the fiddly nature of dial combination locks many safe manufacturers have moved away from them in favour of electronic combination locks and they are rarely offered as an option.
The only comparable Deposit Safe we can offer with a Dial combination lock is the
Burton Teller Deposit V51 but there would be an additional cost to upgrade the lock.
