Why Monrovia Homeowners Choose Strongbox Lock & Safe Co.
Monrovia sits where the flat San Gabriel Valley meets the steep rise of the San Gabriels, and that geography shapes how we serve it. We’ve rekeyed bungalows north of Foothill Boulevard after the Bobcat Fire evacuations and replaced swollen mortise bolts on Myrtle Avenue homes when the Santa Ana winds hit. Our technicians carry ID, wear uniforms, and quote the full price on the phone - no $19 bait, no surprise charges at the door.
Homeowners in the historic districts around Canyon Boulevard and those in the foothill tracts near Monrovia Canyon Park call us because we show up when we say. Over 42 years in these communities, we’ve learned that a locksmith who understands old-growth fir door frames and evacuation rekeying patterns is not the same as one who works strip-mall storefronts on flatland boulevards. Our 90-Day Done Right Promise covers every job in writing. If it is not right, we come back. No paperwork to file, no argument to have.
We answer calls live, 24/7, including holidays. Seniors and veterans receive a standing 5% discount. If you have a written estimate from another company, we will give you a free second opinion.

Why Monrovia’s Climate & Housing Affect Locksmith Work
Monrovia’s position at the base of the San Gabriel Mountains creates conditions you will not find in neighboring Duarte or Arcadia. The cool, damp marine layer that rolls in most mornings gives way to hot, desiccating Santa Ana winds each fall. That swing causes old-growth fir and redwood door frames on pre-WWII homes to swell and contract on a seasonal rhythm. Every October and November, we see a predictable spike in calls from the historic districts: mortise bolts that bound in summer now stick completely, deadlatch faceplates no longer align with strikes, and skeleton-key locks that worked in June refuse to turn.
This is not a matter of forcing the mechanism. A technician who treats a swollen Craftsman door like a modern steel-frame install will split the jamb or destroy irreplaceable hardware. We carry specialty fitting tools and custom strike shims for exactly this work.
Then there is the fire zone reality. Monrovia’s dual identity as a historic bungalow city and an active wildfire evacuation zone - demonstrated starkly when the 2020 Bobcat Fire burned into Monrovia Canyon - creates locksmith demand patterns no flatland city replicates. We regularly handle pre-evacuation key duplication for foothill residents who want family members to have access, and post-evacuation rekeying when homeowners return to properties that emergency personnel accessed or that sat unsecured during panicked departures. A Pasadena shop would not think to market this service. We have been doing it since 2013.

Yes. The pre-WWII Craftsman and Colonial Revival homes north of Foothill Boulevard frequently retain original mortise cylinders and skeleton-key hardware with non-standard door prep. We carry the specialty tools and fitting experience to repair or replace these without damaging original trim. If we cannot source a matching replacement, we will tell you that upfront, not after we have taken the lock apart.

Yes. Properties in the foothill tracts near Monrovia Canyon Park sit in High Fire Hazard Severity Zones, and we have provided post-evacuation rekeying since the Bobcat Fire in 2020. We also offer pre-evacuation key duplication packages so family members or neighbors have access if you are away when evacuation orders hit. Call (877) 664-8139 to arrange either service.

Rekeying is almost always less expensive, typically $25-$45 per lock versus $140-$220 for new deadbolt installation. If your hardware is sound and you simply need old keys to stop working, rekeying is the square deal. We only recommend replacement when the lock is damaged, obsolete, or does not meet your security needs. We will explain which applies to your situation and let you decide.

Our emergency response target is 20-30 minutes across most of Monrovia, including the historic district and Huntington Drive corridor.
