Fast, Reliable Lock Installation & Rekey Across Monrovia
Lock installation and rekeying in Monrovia means working with houses that are often a century old, built tight against the San Gabriel foothills. We know the difference between a 1920s mortise lock that can be rekeyed in 20 minutes and a worn-out Kwikset that should be replaced outright. If you’re in Monrovia and need new locks, a rekey after moving in, or a smart lock retrofit on a Craftsman door that’s settled out of square, call us at (331) 310-8471. The price we quote on the phone is the price on your invoice - that rule has been in place since 2002 and it’s the reason people in Monrovia call us first.
Why Novak Lock & Security Is Monrovia’s Preferred Lock Installation & Rekey Company
Daniel Novak founded this company in 2002 with one rule: write the price down before any work begins. That rule holds for every job in Monrovia, from a basic rekey near Myrtle Avenue to a full Lock Installation & Rekey retrofit in a hillside home off Canyon Boulevard. We’ve installed or serviced more than 60,000 locks and systems, and every single one came with a written price up front and a documented photo record when we left.
Our technicians are background-checked and uniformed, which matters when you’re letting someone into your Monrovia home. Every visit includes a photo record of the work, left with you before we go. And every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. Monrovia homeowners call us because they’ve read the three-star reviews elsewhere and they want the price visible before anyone gets in a van. That’s how we work.
Our Lock Installation & Rekey Services in Monrovia
Smart Lock Installation
Smart lock installation in Monrovia often means retrofitting a door that was hung in 1925 and hasn’t been square since Eisenhower was in office. A Schlage Encode or Yale Assure doesn’t simply drop into a sagging frame - the strike plate has to be adjusted for seasonal movement, because Santa Ana-driven thermal cycling warps those old wooden doors. We install smart locks on original doors north of Foothill Boulevard regularly, and we set the strike so the deadbolt throws cleanly even when the frame moves. Done right, a smart lock on a Monrovia bungalow works every time.
Keyless Entry and Keypad Locks
Keyless entry in Monrovia has a specific wrinkle that flatland cities like Arcadia or El Monte don’t face: evacuation cycles. When a mandatory order lifts, we get calls from homeowners whose keypad locks died during vacancy - batteries drained, codes forgotten, doors seized. A keypad lock installed in Monrovia should be chosen with battery life and remote access in mind, because the next Bobcat Fire scenario will strand you without a working code if the hardware wasn’t set up right. We stock keypad deadbolts and lever sets in our service vehicles and can often retrofit a keypad the same day.
Key Duplication
Key duplication in Monrovia covers more than the Kwikset keys at the hardware store. Homes in the historic district south of Foothill Boulevard frequently run on original mortise keys or obsolete cylinder formats that a big-box machine can’t cut. We duplicate standard keys, high-security Medeco and Mul-T-Lock keys (with proper authorization), and antique mortise keys for Craftsman lock sets. Daniel Novak has been cutting keys for Monrovia’s older homes for over two decades, and we keep the blanks in stock that most locksmiths in the San Gabriel Valley don’t bother carrying.
Biometric and Electronic Locks
Biometric lock installation in Monrovia is growing, particularly in homes north of Hillcrest Boulevard where residents want remote monitoring during fire season. Fingerprint and electronic deadbolts give you audit trails and the ability to grant temporary access - useful if you’re out of town and need to let a neighbor check on the house while evacuation warnings are active. We install and service biometric locks from Baldwin, Yale, and other factory-authorized lines, always with the written price before we start and the photo record when we finish.

Trusted Brands We Service in Monrovia
We’re factory-authorized on Medeco, Mul-T-Lock, Abloy, Baldwin, and Schlage, and we service Yale and Kwikset hardware daily. That means we carry the right pins, cylinders, and tailpieces for Monrovia’s mix of antique mortise work and modern smart locks. If you have a high-security Medeco or Mul-T-Lock system that needs rekeying, we can do it in one visit - no sending keys out, no waiting for a second appointment. Monrovia homeowners with original Baldwin mortise locks get the same treatment: rekey or cylinder swap, not a drill-out.
Common Lock Installation & Rekey Problems We See in Monrovia Homes
- Seized mortise locks after evacuation vacancy. Homes in Monrovia’s foothill neighborhoods sat empty for weeks during the 2020 Bobcat Fire evacuations. When owners returned, many found their 1920s mortise locks seized from disuse and ash infiltration. We rebuild the original cylinder rather than destroying the lock body - a rekey or swap that preserves the hardware a flatland locksmith would drill out.
- Warped original doors throwing deadbolts out of alignment. Canyon mouths above Monrovia funnel Santa Ana winds that heat and cool wooden doors in repeated cycles. A deadbolt installed flush in spring will bind by October. We adjust the strike plate to the frame’s seasonal movement, and we show you what we adjusted.
- Wildfire ash and debris gritting exterior keyways. Ash drifts down through Monrovia Canyon and settles into exterior locks, jamming pin stacks weeks after a fire event. A gritty keyway is a telltale sign. We clean and re-lubricate the cylinder, and if the pins are scored, we rekey it - cheaper than waiting for a key to break off in the lock.
- Keypad locks dead after mandatory evacuations. Batteries drain during vacancy, and the first thing a returning homeowner tries is the keypad. We see this constantly after evacuation orders lift in Monrovia. We install keypad locks with fresh batteries and show you the mechanical key override, because the next evacuation will happen and you don’t want to face it locked out.
Pricing for Lock Installation & Rekey in Monrovia, CA
Here’s what we charge in Monrovia, in writing, before we leave the shop. A standard deadbolt or knob rekey runs $25-$45 per cylinder. Installing a new basic deadbolt on a prepared door runs $95-$160 including hardware and labor. Smart lock installation (Schlage Encode, Yale Assure) runs $180-$320 depending on whether the strike plate needs adjustment for warped frames - and on Monrovia’s older homes, it usually does. Rekeying a mortise lock runs $65-$110 per lock if the cylinder is salvageable. If the mortise body is seized and we have to rebuild the cylinder, that’s $140-$220. Key duplication is $2-$8 for standard keys and $15-$45 for high-security or antique keys with proper authorization. You’ll get the full price on the phone before anyone is dispatched, and there is no call-out surcharge added on arrival. Haven Standard Clause 1: the price on the phone is the price on the invoice.

FAQs - Lock Installation & Rekey in Monrovia
Check the keyway for grit and the throw of the deadbolt on every exterior door, especially if the house sat vacant for more than a week. Ash infiltration and thermal cycling during vacancy are the two failure modes we see most after Monrovia evacuations. If the key feels gritty or the bolt scrapes, call (331) 310-8471 before you force anything - a seized cylinder broken inside the lock is a harder fix than a clean rekey.
Yes, in most cases a 1910s-1930s mortise lock in Monrovia can be rekeyed or cylinder-swapped without replacing the whole lock body. We rebuild original cylinders rather than drilling out the mortise case, which preserves the hardware and costs less than a full replacement. Full replacement is only warranted when the lock body is cracked or the internal springs are spent. Call (331) 310-8471 and describe the lock - Daniel Novak can usually tell you over the phone whether it’s salvageable.
Two reasons: evacuation vacancy drains batteries, and canyon-funneled Santa Ana winds push fine grit into the keypad mechanism. A keypad lock in Monrovia’s foothill neighborhoods faces more environmental stress than the same lock in Arcadia or Temple City. We install keypads with battery indicators and mechanical key overrides, and we show you both before we leave. For an exact quote on a keypad retrofit, call (331) 310-8471.
Yes. In most forced-entry cases the door and frame are structurally sound and only the lock itself is damaged. We rekey or replace the lock hardware, repair the strike plate, and leave the door intact. You don’t need a new door because a deadbolt was forced - you need a locksmith who can assess the actual damage. Call (331) 310-8471 for a written estimate before any work starts.
If you’ve had forced entry during an evacuation, rekey immediately. Otherwise, rekey whenever keys go missing, after a tenant or contractor moves out, or after any period of weeks-long vacancy where you can’t account for every key. Monrovia’s evacuation cycle doesn’t change the basic rule, it just makes the periodic rekey more urgent. Call (331) 310-8471 and we’ll give you a per-lock price in writing before we schedule the visit.
