Monrovia locksmith work splits two ways: rekeying original mortise locks on 1920s craftsman bungalows near Old Town, and cutting transponder keys for late-model cars parked in 91017 driveways. Glendale Lock & Key has served Monrovia since 2018, and we stock hardware for both ends of that spectrum. If you need a rekey, a car key, or someone at your door at an unreasonable hour, call (855) 791-2710.
Why Monrovia Homes Are Different
Monrovia’s housing stock runs in two distinct generations, and each one shapes the work we do. North of Foothill Blvd and east of Myrtle, you’ll find 1920s through 1940s craftsman and Spanish colonial homes. Many still carry their original mortise locksets with skeleton-key cylinders. Those locks were built to last a century, but the climate works against them. Hot, dry foothill summers and Santa Ana wind events pull moisture out of wooden doors until they warp. Deadbolts bind. Old locks seize. When we’re called for a simple rekey on a 1923 bungalow, we often have to source antique mortise cylinders or retrofit modern hardware to match the old door prep.
The 91016 and 91017 zip codes also include 1950s through 1970s ranch tract homes. Those were built with builder-grade knob locksets and hollow-core doors that age poorly. A rekey on a 1962 ranch home frequently turns into a longer conversation about door reinforcement and a Schlage or Kwikset deadbolt upgrade. Winter rains swell frames and misalign strikes, so a lock that worked in October may not throw in February. Monrovia’s terrain adds one more layer: streets climb the San Gabriel foothills, and older homes on raised foundations shift seasonally, which knocks door preps out of square. A good Monrovia locksmith has to read the house before touching the lock.
Styles & brands we work with







Our Main Monrovia Services
Two calls dominate our Monrovia board: people who’ve lost or broken a car key, and people who need a door opened or secured right now. Here’s how each one works in this city.
Car Key Replacement in Monrovia
Modern car keys are not what they were in 1995. A transponder key or proximity fob has a chip that must be programmed to your vehicle’s immobilizer before the ignition will turn. We handle that on-site, in Monrovia driveways and at the curb on Myrtle Ave, including late-model push-to-start systems. Whether you lost the only key or just want a spare before the one you have gives out, we cut and program on the spot. Full breakdown on costs, car makes, and what to bring: Car Key Replacement in Monrovia.

Emergency Locksmith in Monrovia
A lockout on a Monrovia foothill street at midnight is a different problem than a lockout at noon. You need someone who can get there, open the door without damaging a 1920s mortise lock or a 1970s aluminum frame, and charge what they said they would. That’s the service we run. Residential lockouts, broken keys in locks, deadbolts that failed while you were out. Full response details and what to expect: Emergency Locksmith in Monrovia.

Rekey Locks in Monrovia

Rekeying in Monrovia means working around two problems most cities don’t have: original mortise locksets from the 1920s that no longer have replacement cylinders at the hardware store, and modern deadbolts on warped doors that bind when the Santa Anas blow. We rekey the lock you already have rather than replacing it. That keeps your hardware investment intact and eliminates the key-control risk from previous owners, tenants, contractors, or a spare key that’s been circulating the neighborhood. For a deeper look at the service, see Rekey Locks.
Lock Rekey
Signs you need it
You bought a home in Monrovia and you don’t know who still holds a key to the existing deadbolt.
What it costs in Monrovia
A standard single-cylinder deadbolt rekey typically runs $75 – $150 depending on the lock’s condition and whether the cylinder needs cleaning or repair.
How we do it
We remove the cylinder, replace the internal pins so the old keys stop working, and cut you a new set of keys on the spot, keeping your existing hardware in place.
Keyed Alike
Signs you need it
You’re carrying four different keys for your front door, back door, garage side door, and a padlock, and you’re tired of the keychain guessing game.
What it costs in Monrovia
Keying multiple locks alike generally adds $25 – $40 per additional cylinder beyond the first rekey.
How we do it
We pin each of your locks to match a single key, so one key turns every cylinder you want on the same system, without replacing any hardware.
What Rekey Locks Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Standard deadbolt rekey (single cylinder) | $75 – $150 |
| Antique mortise lock rekey | $110 – $190 |
| Key additional locks alike | $25 – $40 per cylinder |
Can you rekey a 1920s mortise lock in Monrovia?
Yes. We stock mortise cylinders for older Schlage and Yale-compatible locksets and can re-pin the original skeleton-key cylinder in most cases. When the cylinder is too worn, we retrofit a modern cylinder into the existing door prep.
How long does a rekey take in Monrovia?
Most residential rekeys run 30 to 45 minutes per lock, though antique mortise locks can stretch closer to an hour if the cylinder needs disassembly and cleaning. Call (855) 791-2710 for a specific estimate.
Brands We Service in Monrovia
We work on the lock you already have, which means carrying parts and pins for the brands Monrovia homes actually use: Schlage, Kwikset, Medeco, and Yale among them. Most common cylinders are restocked in the van. Rare or high-security parts we source through our brands network, usually within one business day.

What Monrovia Customers Say
"Got me back in and the price was fair for the hour. He did arrive closer to 45 minutes than the 20 he estimated, which felt long standing outside, but he was honest that traffic was the problem."
— Megan Norris"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without a fuss."
— Alejandro Morales"Rekeyed every lock in the house the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
— Divya Patel
