Rekeying locks is the most common locksmith job we handle in Monrovia, and the city’s rental-dense housing stock near Old Town and the 210 corridor drives a lot of it. Landlords call us between tenants, renters call us after a move-in, and homeowners call us after a lost key or a falling-out. The older doors here, with their original mortise lock sets and nonstandard backsets, make rekeying both more necessary and more technical than in newer subdivisions. If you need a locksmith in Monrovia, call Tumbler Lock & Key at (877) 265-3856.
Why Monrovia Homes Are Different
Monrovia’s older single-family homes and small apartment courts, especially the 1920s to 1950s bungalows near Old Town, often still have their original mortise lock sets and single-cylinder deadbolts with nonstandard backset. That means a standard replacement knob from a big-box store rarely fits without door prep, and a rekey is usually the smarter, faster fix. The dry, hot summers and Santa Ana wind events dry out and warp wooden doors and frames, so deadbolts and strikes go out of alignment and keys that used to turn smoothly start binding. Dust from those same conditions accelerates wear on exterior lock cylinders. We also get a specific kind of call from the court apartments south of Huntington Drive: a renter comes home in the afternoon, the key won’t turn in an old mortise lock, and the landlord needs it sorted that day. That’s not a job for a generic handyman. It’s a job for someone who knows how a Monrovia lock was built.
Styles & brands we work with
Our Main Monrovia Services
Most Monrovia homeowners and property managers call us for one of three things: rekeying locks after a change of occupant, replacing car keys when they’re lost or broken, or getting back inside during a lockout. Here are two of our core Monrovia services.
Car Key Replacement in Monrovia
As our home base shows, we do more than door locks. We replace car keys for Monrovia drivers, including transponder keys and fobs, which means you don’t have to pay dealership prices or tow your car across the 210. At the Gold Line station lots along Myrtle Avenue, keys get locked in cars. At the foothill trailheads near Canyon Park, keys get dropped on dirt. We come to you in Monrovia, cut and program the key on-site, and get you moving. Call Tumbler Lock & Key at (877) 265-3856 for an exact quote. See our Car Key Replacement in Monrovia page for full details on makes and models.
Emergency Locksmith in Monrovia
A lockout in Monrovia rarely happens at a good time. A renter locks themselves out of a court apartment on a Saturday evening. A family comes back from dinner in Old Town and the front door deadbolt won’t budge. A hiker returns to a locked car at a foothill trailhead after dark. Our Emergency Locksmith in Monrovia service is built around fast response and a calm, direct approach. We tell you the full price on the phone before we dispatch anyone, and that is the price on the invoice. No surprise trip fees, no upsell pressure. Call (877) 265-3856.

Rekey Locks in Monrovia
Rekeying a lock in Monrovia means changing the internal pins so the old key stops working and a new key takes over, and for most Monrovia homes it makes more sense than replacing the hardware. The old mortise locks on a 1930s bungalow near Old Town or a court apartment off Foothill Boulevard are often solid brass and built better than anything new, but they use nonstandard backsets that make replacement knobs a poor fit. Rather than rip out good hardware and prep the door for new parts, we rekey the cylinder. That’s the full Rekey Locks service we bring to Monrovia, and it’s faster and cheaper than replacement in most of the housing stock this city actually has.

What it costs in Monrovia
Standard lock rekeying in Monrovia typically runs $75 to $160 for a single door, depending on the cylinder type and number of keys needed.
How we do it
We remove the cylinder, replace the pins to match a new key, and test the lock for smooth operation, usually in under an hour.

A housemate, caretaker, or contractor still has a key, or you’ve lost one copy and can’t account for it.

What Rekey Locks Costs in Monrovia
| Item | Typical range in Monrovia |
|---|---|
| Single lock rekey | $75 – $160 |
| Additional locks, same visit | $25 – $40 each |
| Labor (standard rekey job) | $50 – $100 per hour |
How long does rekeying take in Monrovia?
Most single-door rekey jobs in Monrovia take 30 to 60 minutes. Old mortise locks on 1920s to 1950s doors can take a little longer if the cylinder needs cleaning or the interior thumb-turn has been painted over. Call (877) 265-3856 for an exact quote.
Is rekeying better than replacing locks in Monrovia?
In most Monrovia homes, yes. Rekeying keeps the original hardware that matches the door’s nonstandard backset, and it costs less than buying and installing new locks. We rekey, we replace, we respond; we’ll tell you honestly which one your door actually needs.
Brands We Service in Monrovia

Pricing for Locksmith in Monrovia, CA
| Service | Typical range in Monrovia |
|---|---|
| Lock rekey, single door | $75 – $160 |
| Additional locks, same visit | $25 – $40 each |
| Standard locksmith labor | $50 – $100 per hour |
| Emergency lockout service | $75 – $150 |
| Car key replacement | $150 – $350 |
| High-security rekey (Mul-T-Lock, Medeco) | $100 – $300 |
What pushes price up in Monrovia is the age of the lock. A painted-over mortise cylinder in an Old Town bungalow takes more labor than a standard deadbolt, and high-security brands like Mul-T-Lock and Medeco cost more because the cylinders and keys are engineered to tighter tolerances. Every quote we give on the phone is the full price; there is no call-out surcharge added on arrival, and no bait-pricing.

What Monrovia Customers Say
"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Ernesto Hernandez"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Ramon Flores"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Beatriz Torres
