A vault door is more than a slab of steel. It is a system of bolts, hinges, combination locks, time locks, and day gates that must work together. When one part slips out of adjustment, the whole vault is at risk. King Locksmith and Doors services UL 608 rated bank vault doors, GSA Class 5 vault doors, and modular vault entrances. We inspect bolt work, oil hinges, check the emergency ventilator, and test every lock so your vault opens on time and stays shut when it should.
Many vaults in the DMV must meet strict rules. Federal sites that store classified material rely on GSA Class 5 vault doors built to AA-D-600D and locks that meet FF-L-2740. Drug distributors and narcotic treatment programs that keep Schedule I and II drugs in a vault must follow DEA rules under 21 CFR 1301.72. Banks depend on UL-rated doors and working time locks. Our technicians help you stay compliant with careful service and clear records.

A GSA Class 5 vault door is built to federal spec AA-D-600D. Government agencies use it to protect classified material, weapons, and other sensitive items. A UL-rated vault door is tested under UL 608 and is common in banks. UL classes range from Class M, rated for 15 minutes, to Class 3, rated for two hours of attack resistance. We service both types.
A day gate is a second, lighter door that sits inside the vault door frame. It lets staff keep the main door open during work hours while still limiting who can walk in. Banks use day gates for daily access. DEA rules under 21 CFR 1301.72 call for a self-closing, self-locking day gate when a Schedule I or II drug vault must stay open for frequent access.
Yes. Our technicians can open vault doors that are locked out by a lost combination, a failed electronic lock, or a time lock problem. We use careful, non-destructive methods whenever possible to protect the door and its rating. Forced entry by an untrained person can damage the bolt work and lead to a costly door replacement. Call us before anyone tries to force it.
