I bought a used safe — should I change the combination?

The short answer

Absolutely, before anything valuable goes in — the seller, their family and possibly a locksmith all know the current one.

A professional combination change is quick and keeps the lock healthy. We'll inspect the bolt work while we're in there.

People also ask

I forgot my safe combination — is it ruined?

Usually not. Professional opening typically preserves the safe, and afterward we change the combination so it opens for you again. Full answer →

My safe's electronic keypad is dead — is everything stuck inside?

No — dead keypads are among our most common safe calls. There are proper ways in, and the lock usually gets repaired or replaced after so the safe ends up better than before. Full answer →

What safe should I buy for home documents and valuables?

Decide fire vs. burglary vs. both (they're different ratings), buy one size larger than today's pile needs, and plan for anchoring — an unanchored safe is a carrying case. Full answer →
