Commercial pin tumbler, Medeco Maxum, transponder — all on board.
38 locks.
One weekend.
Priya Ramanathan manages a 38-unit residential portfolio across the Tenderloin and Lower Haight. On Thursday at 4 PM, she learned Monday's new tenant wave was moving in four days early. Every cylinder needed rekeying before Saturday noon.
Two previous locksmiths quoted 10 days and $6,200. She called Deadbolt at 6:30 PM.


The contractor
kept a copy.
A Pacific Heights estate owner discovered their renovation contractor had duplicated the front door key. Three months later, tools went missing. The homeowner needed every copy invalidated — immediately, permanently.
Standard pin tumbler locks can be copied at any hardware store. Deadbolt installed a Medeco Maxum system with a patented restricted keyway. No locksmith in California can legally cut a duplicate without written authorization from the owner.
Three floors.
One master key.
A 60-person SoMa startup moved into a three-floor building. The CEO needed one key that opened everything. Department heads needed keys that opened their floor and shared spaces. Individual contributors: their office only.
Deadbolt designed and implemented a Grand Master Key hierarchy across 34 cylinders — four access tiers, zero overlap errors. Delivered a cut-sheet and key control log the same day.
